Divergent thinking

Dear Readers,

I would like to resume my blog today with an Easter egg. 

I stumbled upon this talk given by Tina Seelig about Divergent Thinking and related subjects.

Divergent thinking, when combined with convergent thinking results into Design Thinking.

 

Design Thinking is what is needed to create new things and change the world. Sometimes people only see the "convergent" side of this process, because they can only see the result of it. Instead, ideas generation is the most challenging part and often hidden. Even Steve Jobs, before getting it right, have explored plenty of designs he did not hesitate to throw away if they did not meet his standards. 

Nobody get it right from the beginning. But everybody is able to explore the search space of ideas. But also people are afraid to explore this, possibly large, space because they can get lost. Moreover, many assume that sharing one idea means believing that the idea is the best or the right one from the perspective of who generated it. This a wrong assumption. Generated ideas are not right or good. They are just ideas... that need to be validated. Ideas are assumptions, and assumptions need to be validated. Only after this process, one can say if they are good or bad. If you don't do that, you are simply biased. 

This is where convergent thinking unfortunately kick off prematurely. Once an idea is generated, instead of taking position in favor or against it, one should think about how to validate it with a neutral standpoint. Validating, means setup experiments and put the idea at work. Sometimes is very straightforward and brainstorming might be sufficient. Some other times, it can be very challenging and it would require a complex experiment.

In no case, an idea should be classified immediately as a non-sense. Moreover, ideas can be tweaked and made feasible and valuable just by changing the some assumptions that don't work. That is "morphing". As I said before, nobody get it right from the beginning, but there is a high chance that they get it "almost" right.

Another situation is when some assumptions are believed to be validated and in fact they are not. When implemented, these ideas fail just because some of their assumptions were believed true and in reality they were not (e.g. customers like it because I like it). In these situations, one has to have the courage to throw away work done and start from the beginning. This is called "pivoting". 

In my opinion, if pivoting is required often later in the process of developing an idea, it means that too little has been done in the "divergent" phase of design. In other words, ideas were not explored adequatelly.

In the divergeng phase, one can use the "re-framing" technique. This is when, one tries to see things from different perspectives. The idea can be the same, but you look at it in a different way. You do this when you say "let's see this as it was that". In other words, you can use different metaphors.

As pointed out by Tina Seelig, metaphors are a very powerful tool to change perspective. Metaphors are orthogonal to ideas. Of course, adding an additional dimension makes the process more complex and difficult to manage. However, the chances to find the best idea are higher. 

Dealing with metaphors requires to see things differently. If you see ideas differently, the assumptions might change and turn out to be validated. This is something we do for instance when we change market segments or consider a different use of a product. Well, in reality we don't do this, our users do. Yes, because they are not biased like us by "convergent" thinking: they are naturally "divergent". 

That is why, "validated learning" is very helpful. Validated learning is a technique promoted by the Lean Startup Model proposed by Eric Ries. The idea is that assumptions are validated through the building of a Minimal Viable Product (MVP)t that users can test and provide feedback to. Then you learn by measuring the feedback and then iterate the process by integrating what is learned in the next version of the MVP. 

To conclude this post, I would like to stress that being a Design Thinker might be challenging if you work with "convergent" thinkers. They tend to see in black and white whereas you see colors. They see one dimension where you see two (like in Flatland). They blame you to bring distraction where they need focus. They see threats where you see opportunities. And most of all, they fear "pivoting" because they have focused so much energy in developing one single idea that throwing it away would represent a big failure for them. 

Design thinkers know that faillure is the only way to success and they are just fine with it. For 100 bad ideas there might be a good one. They know that the only way to seize it is to rule out the other 99.

So don't be disappointed if you don't find what you expected in the Easter egg.

Happy Easter to everybody!

Usability is not just about flashy animations...

I was browsing the IKEA web site in order to find a suitable carpet for my living room. For this task you need two basic information:

1. the size of the carpet
2. the picture of the carpet's texture

Typically, the previews show the carpet's texture but in the IKEA's web site they do not include the size that it is shown when clicking on the item's preview.

This is a very simple case of usability issue that can be easily solved. It is not about the appearance of the web site but just about what information is relevant and useful for navigating the site.

If the web site is an e-commerce portal, then this issues can result into a loss of revenue due to the increasing customer's abandon rate (i.e. the user visit the site, tries to make a purchase, but the task is boring or too difficult, or just it does not find the necessary information to make the purchase).

If you want to check whether your site have usability problem you can ask help to a usability consulting company such as SimpleUI with which I am currently collaborating.

Less Features, More Freedom!!

Yesterday, I participated to a very interesting workshop part of the LIFT08 conference where one topic of discussion was how to design a mobile infrastructure and interface for empowering and enabling marginalized people to produce multimedia art and eventually get some revenues.

Well, being the topic very interesting, one thing that emerged from the discussion was about design choices. With a vague idea of potential users, it is very difficult to select those features that are expected to be useful to them. So the tendency is to add more and more features with the hope that some of them will be actually be used.

Experience tells us that this is a bad practice. In fact there are two important usability factors here:

  1. Users will use technology in an umpredictably way.
  2. Users will not use (unless forced) messy and cluttered interfaces.

The combinination of these two simple (verifiable) factors led us to the conclusion that it might be better to have simple objects with a great freedom of use. This will enable unpredicted and serendipitous interactions that might be used to understand user needs and improve the design.

So I came with a motto that I checked is not yet present on the web:

Less Features, More Freedom!

Flip3D vs CoverFlow

There is a lot of discussion on the Web about similarities and differences between Vista's Flip3D and Leopard's CoverFlow. Below you can see screenshots of the two interfaces:








Well, the point is: apart from aesthetics, from the user point of view, which one is more useful?

Vista's Flip3D is a substitute of the the ALT-Tab applications switcher. You can now visualize ALL the application windows in the middle of the screen as being "documents" from which select the relevant one.

Leopard offers the same Desktop functionality in a less "obtrusive" way: it's what they call Stacks. Stacks are expandable icons placed in the Dock. You can see below a screenshot of this functionality:




CowerFlow is a new visualization techniques that Apple has bought from SteelSkies. Unlike Flip3D, this technology is not bound to the desktop and can be used in different applications (API). In fact, it is already available in applications such as iTunes, AppleTV, and FrontRow. Enhancing the Finder by CoverFlow allows Mac OS-X user to visually access any type of document by its preview. CoverFlow has been proved to be useful in iTunes because it simply provides user with a better experience.

I did not try Vista's Flip3D, but intuitively I can imagine how much this tool might enhance my user experience with the OS. Switching application should very fast and when I move from an application to another, I don't really care about the preview. I want to switch to the application, that's all. In contrast, is when I browsing the content of my hard-drive that I need to preview the content of the documents.

So what? I believe that, as usual, Microsoft policy is about being impressive but not effective. Vista designers don't care about users, they just wanted to show how good they are at programming 3D interfaces. Maybe, Mac OS-X user interface is less impressive than Vista's one, but certainly more fluid and usable. Special effect are used with parsimony and when they can be of real help in providing a better user experience.

Once again, I am proud of Being a Mac and not a PC!

A nice workshop held in Stanford two years ago...

While trying to cope to the mess in my computer, I discovered a link to a workshop on Ubiquitous Media and Social Infrastructure I attended during my visit in Stanford (August-October 2005).

Below, you can see me while discussing with some students presenting their posters:





The workshop was organized by the Keio university, which is roughly the Japan equivalent of Stanford. The website contains the video recordings of all the speech. It is a nice memory... I hope you will enjoy the talks. One I suggest is that of Clifford Nass, maybe better known for inventing the Microsoft's (annoying) paperclip "Clippy"!!

Would you buy a computer like this?



In this article on Macsimumnews, Dennis Sellers discuss how requests for features for the new iMac might be collected from Apple fans.

Beside the interest about the technical features, it is nice to see how many designers and artists challenge themselves on the Mac playground. Mac computers are really something beyond the scope of a machine. They are a philosophy and a vision!
