Présentation de l'éditeur
Designing the Obvious belongs in the toolbox of every person charged with the design and development of Web-based software, from the CEO to the programming team. Designing the Obvious explores the character traits of great Web applications and uses them as guiding principles of application design so the end result of every project instills customer satisfaction and loyalty. These principles include building only whats necessary, getting users up to speed quickly, preventing and handling errors, and designing for the activity. Designing the Obvious does not offer a one-size-fits-all development process--in fact, it lets you use whatever process you like. Instead, it offers practical advice about how to achieve the qualities of great Web-based applications and consistently and successfully reproduce them.

Hoekman proposes the "unthinkable" for those entrenched into rusty web design practices, but when you step back and reconsider the experiences you've had, his framework makes perfect sense. Here are a couple of thoughts he brings to the table, to give you an idea:
-Design an application that does one thing, and does it very well. For every additional feature, there is more to learn, more to tweak and configure, more to customize, more to read about in the help document, and more that can go wrong.
-People (users) don't always make the right choices. They make comfortable choices... they make choices they know how to make. To deal with this, he supports Goal-Directed (also called Activity-Centered) Design, as opposed to Human-Centered Design.
Web Design anathema? Violation of User Interface "basics"? Maybe it sounds so at first, but if you read through his arguments, you will find them very compelling and may end up (like myself) reconsidering some of your initial assumptions.
One of the reasons why his proposal resonated so much with me is because throughout the book, Hoekman introduces concepts that are not familiar in the Web space, borrowing them from long-established best practices in manufacturing (where I worked the first four years of my professional life), such as:
-Kaizen: improving things constantly, in little tiny ways that add up to gigantic results.
-Poka-Yoke: software "devices" meant to prevent user errors from occurring.
-Pareto (80/20 rule): Good, clean Web application design means that 80 percent of an application's usefulness comes from 20 percent of its features.
For longtime professionals and newcomers into the field of User Experience Design, Hoekman's book has turned into an absolute must read.
If you're like me there is probably considerably more than one thing.
Hoekman lays out the basic principles of web application design clearly and succinctly. He starts by describing some of the practices that designers should adopt in order to understand how their users actually behave and what they really need. These practices are meant to cure readers of the habit of asking users what they want, which frequently results in honest but inaccurate answers. Hoekman's tools of choice for generating understanding are various forms of shadowing users while they do the tasks your application will perform, and his preferred method of documentation is the use case. No one who has worked in software development for any period of time will be surprised at the use case rules he lays out, but the example he gives is a rare glimpse into how the mind of an expert polishes a basic use case into something truly professional.
He next tackles the question of what features to put into your design and which to leave out. Here Hoekman is firmly in the minimalist camp exemplified by 37 Signals. He advocates ruthlessly stripping out "nice to have" features, and simplifying the rest. Although I had previously read much the same argument in "Getting Real", ([...]) once again I found that the example at the end of the chapter gave greater practical insight into how to actually select features to remove.
I found the chapter titled "Support the User's Mental Model" to be the most valuable in the book. As someone who is more often on the project management than the implementation side of web applications, I have often had an engineer propose a feature or refinement that makes perfect logical sense, but for some reason doesn't feel right. After reading this chapter, all of those vague feelings snapped into focus for me. Engineers are so deeply immersed in how the application works, and the possibilities that are available, that they sometimes want to structure interactions in ways that reflect the logic of the code rather than the logic of the activity. Previously I had been attributing most of these errors to the desire to provide more options to the user. Being able to distinguish between the two should help me in approaching these proposals better in the future.
The chapters on helping first time visitors become intermediate users quickly and on handling errors were also valuable, mostly because they focused on the introductory experience. There are dozens of books on design and interactions, but I have yet to see one that focuses exclusively on the crucial first visit of a user to a new site. Since this is where most of our products either succeed or fail, it's great to get some practical advice on how to gently guide a neophyte while still preserving the power a more experienced user will demand. Once again the blow by blow examples that tackle specific interaction problems and solve them are worth their weight in gold.
The rest of the book emphasizes the value of uniformity and novelty, and seemed less useful to me. It's possible that at my intermediate level of knowledge, those were the obvious things I HAVE thought of!
I only had one quibble with the book. Hoekman includes lots and lots of references to web sites and online articles that could be helpful, but each one is buried in the text. A page at the back that simply listed each of these sites would have been very helpful. Or better yet, list them on the author's web site and keep them up to date! What better way to promote yourself as an author long after the original book is dogeared and falling apart?
But this book is an invaluable resource, and one I expect will still be on my shelf long after all the sites it references have gone offline.
The only issue I have with this idea is that some of the exercises he proposes to help you pare things down are (in my opinion) very hard, or impossible. After all, if we were all decisive enough to excise things from the spec when they weren't strictly useful, they probably wouldn't be there in the first place.
Basically, it boils down to this: Figure out exactly what your application does. This is ONE thing. Then, remove everything that doesn't do that. If you can still do that thing, you won, and have a good design. The book goes into greater detail about a lot of things you can do to make your application as smooth for the user as possible, and helps to avoid common pitfalls. All designers should read this book - and all engineers should read it twice.
Clearly and precisely, Robert Hoekman Jr., explains the how's and why's of proper web design. The book not only explains the concepts of common sense designs, but why they should be implemented. The reader is given examples of web sites both wrong and right, for comparison.
The book is laid out in several chapters and covers every aspect of design, from simple registration screens, to complex content editing. The techniques represented show a clear method to allow you, the designer, to create the next application that can rival even the best web sites out there.
Robert also introduces you to a set of tools that can assist you in creating the perfect web application. After reading about them, I registered for several of the free features and even upgraded one to the full pay version. (Thanks Robert!)
Don't think this book is just for programmers. This book is also for web designers, whether graphic designers, Flash designers or otherwise. The book is well rounded and teaches many design from many perspectives.
This book is a must for anyone who designs, writes, edits, critiques or reviews web sites.
5 stars is not enough.
