Parallax Revisited 1 Year of Constraints
Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. July marks the first year of the parallax series. To celebrate we look back on the past year and review our: favourite topic, favourite personal post, favourite post of the other and a review of the formats. You can read Arjen’s post with the same title here.
When I started blogging in the summer of 2008 I decided I would stay away from writing “meta posts”. I never like it when people write about their own blog (how many posts they have made, comments received, visitors had, etc.). If you don’t like that either, then I suggest you skip this post as I am going to break my own rules.

Parallax
When Arjen Vrielink and I realised that we would no longer work together at Stoas Learning, we decided that it would be nice to stay in touch and find a way to continue the conversations we had. Arjen thought it would be a good idea to write a monthly blog post. We would share a title and we would publish at the exact same time linking to each others posts. Neither of us would read what the other had written before the posts were published. I thought “parallax” would be a good name for the series as it is the name for the fact that two viewers looking at the same thing from a different location see something different. We did as we agreed and have now written twelve parallax posts. This is number thirteen.
Formats
Each parallax post comes with restrictions. The idea being that constraints actually induce creativity. We have used different types of constraints. The most simple limitation was on the number of words. We used this a couple of times and each time it forced me to rewrite a lot. This probably created better English (which isn’t my mother tongue as you might have noticed) and more readable posts, but also forced me to leave out arguments and points that I thought were important. Other times we forced each other to use a particular medium (e.g. a video or a type of picture) , we stole a format of a magazine (e.g. the “What on earth is” series by Linux Format) or we used Tweets about an event to tell a story (e.g. Drupaljam). I have come to realise that these constraints can really be helpful in the writing process and I would like to continue to explore new formats.
My favourite post
One of the nicest things that can happen when writing a blog post is receiving comments. It is therefore that my post titled A Design Concept For a Mobile Moodle Application is one of my favourites. Writing the post allowed me to think quite deeply about what a Mobile application for Moodle should look like and it integrated some of the ideas that I had had for a long time. It triggered a lot of discussion with a fast reply from the lead developer from Moodle and it made connections to other people who are making these ideas a reality.
My favourite post written by Arjen
It has been interesting to see how often Arjen and I take a very similar approach to a topic. One example being the similar kind of caveats we have written in reaction to the title of the post. Arjen’s posts are often more blunt than mine and slightly more provocative. Many of his posts have made me laugh out loud.
My favourite post of his is the one titled What on earth is Remote Sensing?. It starts with the classic question: “I’m not interested in another Swami theory, so please …” and then goes on explaining a relatively complex topic, “remote sensing”, in an extremely clear and humorous way. I like it when writers manage to open up a new world for me and that is what Arjen did with this post.
My favourite topic
Parallax has also created the time and space to write about the things that I always meant to write about, but could never get to. The Influence of a Workspace On Performance is probably my favourite topics where this was the case. This post brought together my thoughts on how the environment affects behaviour allowing me to use great examples from people like Corbusier, Hans Monderman, Jane Jacobs and David Leon (and from products like IE6). These topic continues to fascinate me and I would gladly write another post exploring some of these ideas further.
The future of parallax
Looking back I can now clearly see the way forward for Parallax. I think it has more than delivered on what it set out to do:
- It made me stay in touch with Arjen: at least every month we have some email back and forth on the topic and the constraints and sometimes we do things together so that we can write about it.
- It helps me accomplish one of the main goals of my blog: reflection. I am not naturally a very reflective person and don’t take the time to think (every second of open time is spent reading or listening to informative podcasts, I never stare in the distance and ponder, sadly making my morning shower the most reflective part of the day). Writing is reflecting and thinking and would be worth it even if nobody would ever read this.
- It allows me to react on my very “corporate” job. I can, covertly, challenge some of the ways of working in my company and think about doing things differently.
- It opens up conversations with people from all over the world.
The one thing that I would like to do in the future is to get more guest writers to participate. I think it would be great to have a constantly changing third voice to our posts. I hope Arjen agrees!
Christopher Alexander’s “A Pattern Language”

A Pattern Language
I have just finished reading Christopher Alexander‘s A Pattern Language: Towns – Buildings – Construction, one of the most wonderful books I have read in years.
The scope of the book is incredible. It sets out, in plain terms, to empower people to design, build and shape their own surroundings. It does this by creating a “pattern language”, a kind of generative grammar with 253 patterns that can be used to make things. The patterns move from big town scale patterns (e.g. The Distribution of Towns, Magic of the City, Web of Shopping, Nine per Cent Parking), via medium building scale patterns (e.g. Wings of Light, Intimacy Gradient, Staircase as a Stage) to small construction scale patterns (e.g. Structure follows Social Spaces, Low Sill, Filtered Light, Different Chairs).
Each pattern is described in a similar way: there is a picture showing an archetypal example of the pattern, then a paragraph describing the context of the pattern (in which larger patterns does this pattern fit), next in bold a headline giving the essence of the problem, then a research based exploration of the problem, next in bold the solution stated as an instruction, then a diagram as a visual way of describing the solution and finally a paragraph describing which smaller patterns can help this pattern. Each pattern also comes with a label signifying how sure the authors are that this truly is an universal pattern.
The breadth of topics in the book is baffling (it took the authors about seven years to research and write it). Let me just give you some random quotes to show you what I mean (doing the book a gross injustice by leaving out a lot of context).
On the magic of a cities:
The magic of a great city comes from the enormous specialization of human effort there. Only a city such as New York can support a restaurant where you can eat chocolate-covered ants, or buy three-hundred-year-old books of poems, or find a Caribbean steel band playing with American Folk singers.
On the evils of supermarkets:
It is true that the large supermarkets do have a great variety of foods. But this “variety” is still centrally purchased, centrally warehoused, and still has the staleness of mass merchandise. In addition, there is no human contact left, only rows of shelves and then a harried encounter with the check-out man who takes your money.
On grave sites:
No people who turn their backs on death can be alive. The presence of the dead among the living will be a daily fact in any society which encourages its people to live.
On why buildings should have gradients of intimacy:
When there is a gradient of this kind, people can give each encounter different shades of meaning, by choosing its position on the gradient very carefully. In a building which has its rooms so interlaced that there is no clearly defined gradient of intimacy, it is not possible to choose the spot for any particular encounter so carefully; and it is therefore impossible to give the encounter this dimension of added meaning by the choice of space. This homogeneity of space, where every room has a similar degree of intimacy, rubs out all possible subtlety of social interaction in the building.
On why your windows should have relatively small panes:
[Thomas Markus] points out that small and narrow windows afford different views from different positions in the room, while the view tends to be the same through large windows or horizontal ones. We believe that the same thing, almost exactly, happens within the window frame itself. [..] The view becomes alive because the small panes make it so.
On lighting every room from two sides:
When they have a choice, people will always gravitate to those rooms which have light on two sides, and leave the rooms which are lit only from one side unused and empty.
This pattern, perhaps more than any other single pattern determines the success or failure of a room. The arrangement of daylight in a room, and the presence of windows on two sided, is fundamental. If you build a room with light on one side only, you can be almost certain that you are wasting your money.
On modern impersonal interior design:
Do not be tricked into believing that modern decor must be slick or psychedelic or “natural” or “modern art,” or “plants” or anything else that current taste-makers claim. It is most beautiful when it comes straight from your life – the things you care for, the things that tell your story.
On high buildings (imposing a four story limit):
There is abundant evidence to show that high building make people crazy.
High buildings have no genuine advantages, except in speculative gains for banks and land owners. They are not cheaper, they do not help create open space, they destroy the townscape, they destroy social life, they promote crime, they make life difficult for children, they are expensive to maintain, they wreck the open spaces near them, and they damage light and air and view. But quite apart from all this, which shows that they aren’t very sensible, empirical evidence shows that they can actually damage people’s minds and feelings.
I could go on and on…
Written in 1977 it is clear that this is a very “seventies” book. The belief in what we in The Netherlands would call “De maakbaarheid van de samenleving” (the ability to create/design/mold society) is very high. It was interesting to reflect on where I grew up and how much of that place was designed according to the same kind of thinking and ideals. I could also find many of seventies based educational philosophy of the school I used to work at in the book. The open doors, the integration of inside and outside, there are even some very explicit ideas on education and learning in the book.
Although many of the patterns are probably very universal (they are very human), I do think the book has some strong cultural biases. This doesn’t make it less valuable though.
The book has really made me want to scratch my own creator’s itch. It makes you want to design things. (Apparently Will Wright, the creator of SimCity, wanted to create this game after reading the book).
What I want to create, inspired by this book, is not a town or a house. I want to write a new pattern language. Wouldn’t it be great if we had a generative grammar for technology enhanced education (or using another term, online learning events)? I see that there have been some attempts to do this already (here and here), but I would love to create a much more extensive work that is in the style of Alexander. Is there anybody who would like to help me? Shall I start a wiki?
If you want more information about the book, then go to its website or read hyperlinked summaries of all patterns.
ReWork Rehashed
Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. For this post we agreed to write about the 37signals book Rework. Each of us will write about the three things in the book that we already do, about three things we will do from now on going forward and about three things that we wish our employers would do from now on. You can read Arjen’s post with the same title here.
Jason Fried and David Heinemeier Hansson of 37signals and Ruby on Rails fame have just written a new book titled: Rework (you can download a free PDF excerpt). Reading it gave me an ambivalent feeling: these authors are obviously very good in what they do and they have managed to build a successful business monetizing different parts of their talents, but the book feels like a monetization effort too and the number of words per Euro are very low. Arjen Vrielink has written a quite damning review on Goodreads.
Nonetheless it has some interesting lessons to offer. It has about 100 pieces of advice for people starting their own business or working in a business. Some of the advice I already practice, some advice I will try to practice from now on and I wish that the company I work for would practice some of the advice going forward.
Three chapters about things I already do:
Build an audience (page 170)
Traditional PR and marketing is about going out and trying to reach people. The ubiquity of the Internet allows you to let people come to you instead of the other way around.
When you build an audience, you don’t have to buy people’s attention – they give it to you. This is huge advantage.
So build an audience. Speak, write, blog, tweet, make videos – whatever. Share information that’s valuable and you’ll slowly but surely build a loyal audience. Then when you need to get the word out, the right people will already be listening.
Emulate chefs (page 176)
In this chapter the authors make a case for sharing everything you know, something which is anathema in the business world. They use famous chefs as an analogy. The best chefs share their most valuable recipes in their cookbooks. Why? Because they know that their business as a whole cannot be copied. What better way to show you are an excellent cook, then by sharing your recipes?
I am convinced that there are only benefits to sharing everything I know about educational technology and innovation with anybody who is willing to listen. Doing this is the only way to take part in the incredibly valuable discourse on this topic and taking as much out of it as possible.
Forget about formal education (page 215)
Companies still over-value formal education from. I have personally decided to attend as little formal education as possible from here on further. The key qualities that somebody needs to have are curiosity and the ability to learn. If you combine these two, then there is a whole world out there from which you educate yourself. You don’t have to go and sit in a stuffy classroom and listen to some academic lecturing. Don’t get me wrong: academics are hugely valuable. It is just that you don’t have to join a university to engage with them.
Three chapters about things I will try to do from now on:
Embrace constraints (page 67)
This chapter starts as follows:
“I don’t have enough time/money/people/experience.” Stop whining. Less is a good thing. Constraints are advantages in disguise. Limited resources force you to make do with what you’ve got. There’s no room for waste. And that forces you to be creative.
This is a principle that I am already highly aware of (it is actually embedded in every introduction to any Parallax post on this blog). It is not something I am naturally good in though. I love gadgets and these things often create a lot of extra affordances and thus complexity. I need to tone this down to allow a better focus on things that really matter. First step: “downgrade” my current Ubuntu 10.04 setup which allows me a lot of flexibility (and gives me wobbly windows, that’s not me by the way) to the Ubuntu Netbook edition.
Focus on what won’t change (page 85)
This is probably advice that anybody tasked with working on innovation should heed to. Naturally we like to be focussed on the next big thing. The danger is that you will focus on fashion instead of on substance.
The core of your business should be built around things that won’t change. Things that people are going to want today and ten years from now. Those are the things you should invest.
I will try and use this advice while thinking about the next iteration of our learning landscape. Which aspects are lasting needs and wishes and which are just fads?
Interruption is the enemy of productivity (page 104)
I work in an office with about 10 other colleagues (if everybody is in). During a working day I receive about 50 emails in my work Outlook inbox and have multiple instant messaging conversations. This means that I barely have a couple of minutes without any interruptions. I have to admit that I am probably the cause of many interruptions too, as I constantly share the things I find fascinating or funny with my co-workers.
This is definitely not beneficial for my ability to do work on things that require a bit more concentration and need me to be focussed. It takes a lot of time to write anything which is more than a page of two for example. Usually I can only do it if I work from home and I turn Outlook off. From now on I will try to block a couple of hours every week during which I will sit by myself, turn off my phones, IM and email, refuse to look at Google Reader and just work.
It is as the authors say:
Your day in under siege by interruptions. It’s on you to fight back.
Three chapters about things I wish my employer would do going forward:
Meetings are toxic (page 108, available in the free excerpt)
This one is pretty obvious, but we still have a complete meeting culture. Everybody knows that meetings are not very effective at what their intent is to do and still we have way to many. Some of the reasons the authors give for why meetings are this bad are:
- They usually convey an abysmally small amount of information per minute
- They require thorough preparation that most people don’t have time for.
- They often include at least one moron who inevitably gets his turn to waste everyone’s time with nonsense
- Meetings procreate. One meeting leads to another meeting leads to another…
If you still need to have a meeting I like their simple rules:
- Set a timer. When it rings, meeting’s over. Period.
- Invite as few people as possible.
- Always have a clear agenda.
- Begin with a specific problem.
- Meet at the site of the problem instead of a conference room. Point to real things and suggest real changes.
- End with a solution and make someone responsible for implementing it.
I think we are especially guilty of inviting too many people to meetings and I would love to meet at the site of a problem instead of a conference room, but am not sure how this is done with IT related issues.
Don’t write it down (page 164)
We spend an inordinate amount of time capturing everything everybody says, needs and wants. We have hundreds of Excel files containing lists of requirements, feature/enhancements requests, issues, etc. We probably spend more time managing these spreadsheets than working on the issues that these spreadsheets are an abstraction of.
There’s no need for a spreadsheet, database, or filing system. The requests that really matter are the ones you’ll hear over and over. After a while, you won’t be able to forget them. Your customers will be your memory. They’ll keep reminding you. They’ll show you which things you truly need to worry about.
Don’t scar on the first cut (page 260)
The second something goes wrong, the natural tendency is to create a policy. “Someone’s wearing shorts!? We need a dress code!” No, you don’t. You just need to tell John not to wear shorts again.
This is how bureaucracies are born according to the authors. They consider policies “organizational scar tissue”. I work for a company that, like most other I am sure, is very scarred. Let’s all stop scarring it more!
I have to admit that a list of three was severely limiting when it came to wishes for my employer. I would have like to have the opportunity to add: Ignore the real world (page 13), Illusions of agreement (page 97), Hire managers of one (page 220) and They’re not thirteen (page 255).
5 Things I Cannot Live Without
Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. For this post we agreed to write about things we cannot live without. The restriction is that the things should have a hierarchical relationship where the lowest level of hierarchy is the microprocessor and the highest level is the Internet. Each thing should be described in 100 words. You can read Arjen’s post with the same title here.
Please don’t take the title of this post too literally: yes, even I realise that I will be able to live without these things. Instead consider this a tribute to these five things. Also be aware that the title is not “The 5 Things I Cannot Live Without”, there are many other things that I find way more useful and crucial (think bed, dishwasher, etc.).
So here goes, in a loose hierarchy from local to global:
1. The Microprocessor
What do you know about the microprocessor? If it as much as I used to, then it will be very little! Did you know that the first microprocessors appeared in the early seventies and that they were mostly used for calculators? Did you know that their capacity follows Moore’s law? Did you know that microprocessors not only integrated in computers, but also in cars, toasters, TVs, dishwashers (again!) and most other electrical equipment with some advanced functionality? Finally, did you know the Wikipedia article for Microprocessors needs additional citations and references? Why don’t you get to work and fix it?
2. My iPhone
I don’t think I have yet waxed lyrical about my iPhone. First of all I am late to the party: I have only bought one last December. This is because I resisted buying a closed down Apple product for as long as possible. I really really wanted to buy an Android phone, but all the ones that I tried were seriously less capable than the iPhone. So why is it that much better? Because thought has been put into every single element of the software and hardware design. Nothing is accidental, everything is considered. No other company is there yet.
3. Xs4all
My Internet provider is XS4ALL. There are a couple of reasons why this will be the case for the foreseeable future (even though their price/speed ratio is not competitive):
- XS4ALL is consistently the best provider in the Netherlands.
- Their corporate values and activism are excellent. See this campaign for an example.
- They have repeatedly shown they have a backbone. Their support of Karin Spaink in her Scientology case is the best example of this.
- Innovation is important to them.
- When you call their helpdesk (at a number which has normal rates), you get competent staff.
4. Google Services
Over the last couple of years I have come to rely more and more on Google’s services. So much so that it has become increasingly hard to even list all the Google services that I have an account for or use regularly otherwise. As an excercise I have used this Wikipedia page to list all the products I use regularly (on Ubuntu or iPhone): Chrome, Sketchup, Gears, Calendar, Gmail, Product Search, Reader, Apps, Feedburner, Youtube, OpenSocial, Maps, Aardvark, Alerts, Translate, Groups, Image Search, Scholar, Web search, Analytics, Gapminder, Trends and Zeitgeist. Couldn’t be bothered to link them all: Google them!
5. The Internet
It is a cliché to call the Internet a “game changer”. However, it cannot be denied that it is the most disruptive technology out there. It creates feasibility spaces for social practice (thank you Benkler) and it forces you to rethink traditional ways of doing things. In the field of educational technology for example it has led to, among other things, new course paradigms, an Edupunk movement and deep critiques of the learning function. We cannot fathom what the near future of the Internet will look like as the pace of change is continually accelerating. I cannot wait for it!
P.S. This post was inspired by Techcruch’s Products I Can’t Live Without.
Learning in 3D: Please Join My Reading Group
My company is piloting serious gaming in the learning domain using an immersive 3D environment based on the Unreal engine. We are on the cusp of developing a game around hazard recognition scenarios that are based on real life experiences. Because of this I am reading up on serious gaming and game design in general. After finishing the brilliant The Art of Game Design by Jesse Schell (more about that book in a later post), I now want to tackle Learning in 3D, Adding a New Dimension to Enterprise Learning and Collaboration by Kapp and O’Driscoll.
I have decided to start a reading group which will read the ten chapters of the book in ten weeks (there is a preview of the chapters here). We will use blogs, Twitter, Delicious and a weekly teleconference to communicate around the book.
So how will this work?
Goal
The book provides principles for architecting 3D learning experiences (including a maturity model for immersive technologies) and has lessons on and examples of implementations in enterprise situations. The goal of the reading group is to actively internalise these lessons and see how they can be applied in our own organisation(s).
Participants
As I want this reading group to impact the learning function in my own organisation I intend for about 50% of the participants to work for Shell and for the rest to come from my network outside of Shell. The minimum number of participants is 5 (doing two chapters each) and the maximum is 40 (four people per chapter and incidentally the limit of our teleconferencing solution). Everybody will have to acquire their own copy of the book. (I used the Book Depository to buy this book, as they have free shipping, note that I will earn a small referral fee if you click this link and then buy the book).
Process
The reading group will have a weekly rhythm with a particular chapter of the book as the focus of attention. The following activities will happen every week:
- One or more people will be assigned to write a summary of the chapter on their blog (if they don’t have a blog, they email me the summary and I will publish it on this blog). The summary ends with at least one multiple choice poll and a discussion question/proposition, both used as input for the teleconference.
- All reading group participants will be tweeting questions and comments about the book (using a designated hashtag, see below).
- Each participant will try to add at least one interesting link to Delicious (again with a hashtag) that relates to the chapter of that week.
- At the end of the week (actually on a Monday), there is a teleconference where the summarisers for that week lead a discussion about the chapter, using the poll and the discussion question/proposition as input.
Hashtag and aggregation
All Delicious URLs, blogposts and Tweets should be tagged with the #Lin3DRG hash tag (stands for: Learning in 3D Reading Group). This will allow me to try some smart ways of aggregating and displaying the data using things like Yahoo Pipes or Downes’ gRSShopper. I promise to write another post on my aggregation strategies.
When and where?
It is going to be a virtual affair, co-creating on the web. We will start reading on April 19th, will have our first weekly 30 minute teleconference on Monday April 26th at 15:30 Amsterdam time and will close out on June 28th (so we will have 10 telcons on ten consecutive Mondays at the same time, it is not a problem if you miss one, we will record them).
Do you want to join the reading group? Then please fill out a comment with your name, email address, blog URL (not required) and any comments or questions you might have at the bottom of this post. I will get back to you with your assigned chapter(s), some more information on the process and the call in details for the teleconference. You can put your name down until Monday April 19th.
I am really looking forward to it!
Book Review: Moodle 1.9 Teaching Techniques
Just over a year ago I reviewed four Moodle books published by Packt Publishing. Since then, a lot of new Moodle titles have been added to their catalogue. Richard Dias, Marketing Research Executive at Packt, has kindly sent me a copy of one of these new titles for review: Moodle 1.9 Teaching Techniques by William Rice and Susan Smith Nash, first published in January 2010.
William Rice has already published a couple of books with Packt. This book seems to be an effort by Susan Smith Nash to build on an earlier version of the book by Rice. She adds some learning theory and instructional design essentials to the earlier text.
The fact that this is an update of a much older book, doesn’t work very well. Let me share some examples of where it goes wrong:
- Chapter 2 used to be called “Forum Solutions”, now it has been retitled to “Instructional Material”. This is weird: Moodle’s core functionality and strongest pedagogical tool is first introduced as a way to clearly display course information and structure. Then on page 25 there is a paragraph titled “Creating a Separate Group for Each Student”. The context from the earlier book (you might want to do this to create private conversations with students) is omitted, making it a confusing set of pages.
- Chapter 4 has a section that explains how you can exclude quiz grades from a particular quiz in the grade book. The screenshots and explanations are taken from an earlier version of Moodle and do not relate to Moodle 1.9. Moodle 1.9 has a completely different grade book (and has been released since March 2008). It is unforgivable for a book that is published in 2010 to get this wrong. I don’t understand how the reviewer missed this. Hopefully a corrected version will be published as an erratum.
- The introduction to the book explains that a basic level of Moodle understanding is assumed for the reader as it wants to focus on learning theory. However it then spends more than 5 (of its 193) pages on explaining what an IP address is and how it can be used to restrict access to a quiz. It gets the Linux part on how to see your IP address wrong (another one for the errata).
The book doesn’t really make optimal use of the new and advanced functionality that Moodle 1.9 has on offer. Two examples:
- The concept of “groups” is used in the book in some descriptions of course activities (although not enough to call for its own spot in the index), but the concept of “groupings” isn’t mentioned anywhere. If I were to teach a course with Moodle tomorrow, I would definitely use this functionality as it allows you to be much more flexible in your course design.
- Ever since Moodle 1.7 it has been possible to play with roles and capabilities in Moodle. That functionality is relatively hard to understand and needed some maturation. It is much more usable now in Moodle 1.9. This functionality is only used once in the book (during the discussion on forums) and isn’t explained well enough to my taste.
Does the book have some valuable things to offer? It is not all bad:
- Some of the introductions to learning concepts are theories are good starting points for further exploration. For example, I liked the reference to Bruner’s “scaffolding” concept and spent some time reading the Wikipedia article on instructional scaffolding.
- The pages on basic chat etiquette and wiki etiquette are quite useful. They describe rules you can agree on with your students to make the online learning process more pleasurable.
- The ways of using the choice activity have been slightly expanded compared to the earlier version of the book.
- The last chapter has a nice example of a capstone project assignment that you could adapt for your own teaching. To use the workshop module as the basis for this project assignment is a bit risky, as I would not recommend anybody to use the workshop module in its current state (Moodle 2.0 should solve that problem).
All in all I would not recommend anybody to get this book. If you have 30 euros to spend on a Moodle book (this book isn’t cheap!) choose one of the ones I recommend here. If you have a basic understanding of Moodle and are looking for generalised teaching techniques for online courses you are much better served by Gilly Salmon‘s work on e-moderation (see E-moderating and E-tivities).
Hopefully I can be more enthusiastic about the next Packt title I get to review…
Kaizen versus Good Enough
Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. For this post we agreed to write about how Kaizen (the philosophy of continuous improvement) relates to the rise of the Good Enough paradigm. The post also has to include a non-digital example of Kaizen versus Good Enough. You can read Arjen’s post with the same title here.
The world is full of badly designed things. I find this infuriating. A little bit of thought by the designer could make many things so much easier to use. My favourite book on this topic is The Design of Everyday Things by Donald Norman. It is years ago since I read the book, but I can still remember Norman agitating against all kind of design flaws: why would an object as simple as a door need a manual (“push”). I have therefore decided to start a new Twitter account titled unusablestuff in which I post pictures of things that fail to be usable.
Through Alper I recently learnt about the Japanese concept of Kaizen. This is a philosophy of continuous improvement that aims to eliminate waste (wasted time, wasted costs, wasted opportunities, etc.). Kaizen as described on Wikipedia is very much a particular process that you can go through with a group of people:
Kaizen is a daily activity, the purpose of which goes beyond simple productivity improvement. It is also a process that, when done correctly, humanizes the workplace, eliminates overly hard work [..], and teaches people how to perform experiments on their work using the scientific method and how to learn to spot and eliminate waste in business processes.
I’d also like to see it as being a mindset.
Another thing I recently read was a Wired article titled: The Good Enough Revolution: When Cheap and Simple is just Fine.
Cheap, fast, simple tools are suddenly everywhere. We get our breaking news from blogs, we make spotty long-distance calls on Skype, we watch video on small computer screens rather than TVs, and more and more of us are carrying around dinky, low-power netbook computers that are just good enough to meet our surfing and emailing needs. The low end has never been riding higher. [...]
what consumers want from the products and services they buy is fundamentally changing. We now favor flexibility over high fidelity, convenience over features, quick and dirty over slow and polished. Having it here and now is more important than having it perfect. These changes run so deep and wide, they’re actually altering what we mean when we describe a product as “high-quality.”
The article is full of examples where cheap, convenient and fast wins out over high quality. Think netbooks, MP3 files and the Flip videocamera.
Both ideas have their appeal to me, but at a superficial level they might seem to contradict each other. Why would you spend a lot of time trying to continually improve on something, when good enough is just good enough? This contradiction isn’t truly there. Good enough is essentially relevant at a higher level than Kaizen. Good enough means you design for a specific task, context, audience or zeitgeist and don’t add things that aren’t necessary. It is about simplicity and lowering the costs, but not about lowering the design effort. Kaizen is about the details: once you have decided to build a netbook (smaller screen, less processing power, but good enough for basic browsing on the net), you should still make sure to design it in such a way that people can use with a little waste as possible.
Let’s look at garbage bins as an example. A garbage bin is a relatively simple product. It is a bin with a lid that can hold a bag in which you put the garbage. Oscar lives in one of the classic bins. In essence this is good enough. You don’t need auto-incinerators, sensors that tell you when the bag is full, odour protection, etc. The simple bin-lid-bag concept does have a couple of issues and problems that can be solved with good design.
The Brabantia 30 liter Retro Bin is a bin that has done exactly this. What problems are solved with the design of this bin and how?
Problem: Sometimes you need two hands to get your garbage in the bin. If you have to scrape some leftover peels from a cutting board for example. In that case you have no hands free to lift the lid of the bin.
Solution: You create a bin with a foot-pedal. A foot-pedal also keeps you hands clean as you don’t have to touch the lid of the bin which is often dirty.
Problem: When the bin is empty, pressing the pedal might make the bin move.
Solution: A rubber ring at the bottom prevents the bin from moving on any flooring.

Problem: It can be irritating to constantly have to press the pedal if you want to throw away multiple things and have to walk back and forth to get the garbage to throw in the bin.
Solution: Hinge the lid in such a way that if it opens all the way it stays open. Allow this to be done by a persistent movement of the foot on the pedal.
Problem: If the bag gets really full (by pressing down the garbage) it might press against the mechanism that is used to open the bin, making it hard to open.
Solution: Make sure that the mechanism for opening the lid on the basis of the pedal movement lies completely outside of the bin and is unaffected by the pressure.
Problem: When you put in a new bag it often happens that there is air trapped between the bag and the bin. This makes it hard to throw aways things as the full space of the bag is not used.
Solution: Put little holes in the top of the bags. This allows the air to escape when putting in a new bag.
Problem: There is often a vacuüm between the bag and the bin when you try to lift a full bag out. This gives you the feeling that the bag is stuck.
Solution: Have little holes in bottom of the sides of the bin. This way air can come in, preventing the vacuüm. Brabantia rightly thought that holes at the side of a bin look a bit weird, so they have created an inner bin and outer bin. This also solves an aesthetic (if not design) problem: the top edge of the bag being shown. This top edge now hides between the inner and the outer bin.
Problem: A lot of garbage has some liquid components. These liquids sometimes drip from the bottom of the bag.
Solution: Create an extra strong bottom for the bag of an extra impenetrable plastic.
Problem: When a bag is full it can be hard to tie it up.
Solution: First make sure that the bag is slightly bigger than the bin. Once the bag is out of the bin, the garbage has more space to spread and the top of the bag will have more space to tie up. Next, have a built-in string that can be used to tie up the bag (also highly useful for lifting out the bag). Make sure that this string is long enough to make for an easy knot.
I have had all these problems with garbage bins at some point, the Brabantia bin solves them all.
Many people will probably consider me a whiner (there are bigger problems in the world, can’t you get over these minor garbage issues?) or a weirdo (garbage bins, honestly?) and both are probably true, but that doesn’t negate my point. Getting a product on the market requires that is designed. Now think about the extra design effort to create a bin that solves common bin problems. How many more man months for the Brabantia design than for the classic “Oscar bin”? Now imagine the small problems that a user of a classic garbage bin encounters and multiply them by all the garbage bin users in this world. Any idea how many times an hour something is spilled in this world because there is no pedal on the bin? People like to blame themselves (“I am so terribly clumsy”), I like to blame the designer. Why not just spend some extra design effort and get it right?
I want to draw an analogy with the design of software. I think the believe in Kaizen is what makes Apple products stand out. The example I love to show people is the difference in the calculator on the Symbian S60 3rd edition (I used it on the Nokia E71, my previous phone) and on the iPhone (my current phone).
A calculator is a simple thing. Most people only need addition, subtraction, multiplication and division capabilities. Both default calculators deliver exactly this functionality. Nokia’s effort looks like this:

Nokia's default calculator
You need to use the keyboard (there are designated keys for the numbers) and the D-pad to make a calculation. The D-pad is necessary to navigate from one operator to the next. To do a simple calculation like 6 / 2 = 3 requires you to press eleven buttons!
The iPhone calculator looks like this:

iPhone's default calculator
You just use your finger to tap the right numbers and operators. 6 / 2 = 3 only requires four finger taps.
It is not just the touch interface that makes it possible to have a great working calculator. I managed to download another calculator for the Nokia phone, Calcium. It looks like this:

Calcium calculator
This calculator makes clever use of natural mapping to create a calculator that is as easy, if not easier, to use as Apple’s calculator. 6 / 2 = 3 takes indeed four button presses. Nokia could have made this. The fact that Nokia was willing to ship a phone with the default calculator as it was is one of the reasons why I have a hard time believing they have a bright future in the smartphone space.
In a next post I might rant about how many designers think the whole world is right-handed. Do you have any thoughts on design?
