RE: [agile-usability] Re: Craftmanship doesn't scale... hence usability?
- Now that's interesting. We're entering a testing phase for our latest version and I'm going to try that. Our software isn't as "project' focused as your great software is, but I'm sure we can figure out something in the same spirit.Thanks,Jade OhlhauserProduct ManagerRPM Softwarewww.rpmsoftware.com 403-265-6727

Subject: RE: [agile-usability] Re: Craftmanship doesn't scale... hence usability?This is a great way to personalize for the team the usability issues that our customers face every day. We often will assign the whole team (developers, documentation, QA, usability people, etc.) a weekly project to do. The project will focus on a real-world task that our users rely on our software for (and not something small like entering a set of data..that isn't really representative of how users will be using the whole application, is it). We try to test something that encompasses a larger workflow so we get a more realistic idea of the overall experience. Our product specialist will obtain real work samples from a customer, and that is what we will work with (instead of us providing our own work samples, which are often set-up for success). The project is something that people on the team can pick up and work on intermittently, while taking a break from their real work. At the end of the week, we have a meeting where each person on the team presents their results for the project, and talks about the experience. It is a great way for all of us to step out of our roles and find out what it's like to use the software from a user's perspective.---

I mostly agree.
Developpers can't catch ALL usability issues because they know the interface
too well. So you still need to test with real users (that's point (1)). But
in my experience, developpers CAN intercept MANY important usability issues,
especially if, as you propose in (2), they do more than "play around" with
the system and try to carry out realistic tasks (which could be crafted by a
The point I was trying to make is that I believe there is a lot of value in
having the development team as a whole be actively involed in usability
design and testing. It educates the whole team about usability issues. After
a while, I bet you would find developpers:
(a) Truly valuing usability (now wouldn't THAT be nice).
(b) Independantly finding usability issues that were missed by testing with
real users (after all, testing can only find issues that show up in the
specific scenarios that were tried)
(c) Independantly making good design decisions for minor things (as a
usability expert, wouldn't you prefer to spend more of your time on the big
picture instead of whether a list should be a pick list or a series of radio
(d) Turning to usability experts for advice on the more difficult issues.
This may sound threatening to usability experts but it's not. Basically it
means that their role would move from being the Usability Police to being a
Usability Coach and Partner.
This is exactly what has happened with unit testing and design in XP.
Instead of having a separate Architecture Police or Quality Police, everyone
is actively involed in design (constant refactoring) and testing (unit
testing) and loving it. Typically though, you still need at least one person
on the team who is an expert designer and/or tester and acts as a "gardener"
and coach for Architecture and Quality. And those people are highly valued.
(1) Developers' inside-out knowledge of how the user interface was
constructed and how it functions handicaps them in actually experiencing the
(2) "Playing around with" is not using.
More payoff can be obtained if someone independent creates realistic and
challenging usage scenarios for the developers to carry out with
representative volume and complexity ("complete the following 28 new patient
admissions and correct the following 12 billing errors while intermittently
interrupting each other"). An application that can feel just fine when you
are freely exploring it without pressure and with no particular goal in mind
can turn out to be completely unacceptable under realistic and repetitive
This sort of trial use is less fun than a "celebration" but more useful in
gaining insight into user needs. Over time, developers who do this will find
their design and development practices gradually morph. For example, some
developers tend to see modal dialogs as the solution to every interaction
problem. Only when they experience them popping up in their faces at every
turn and having to launch-act-and-close 28 times in a row do they start
thinking about within-context alternatives.
