Users, Usability, & Accessibility

In my last post, I asked how much more effective my prototype would have been if we had started with the “compelling story” and went from there? The problem from the start was failing to recognize who my user group consisted of. We assumed that since we were working on an application prototype, our users were a fictional (and generic) set of people who would eventually be our customers. The end result was a feature rich application that didn’t solve any single business problem.

In reality, the people performing the demonstration were the real users. Developing features to help them tell their story (and win the company more business) should have been our only goal.

Around the time I realized this, I also discovered two developments in user interface design - Usability and Accessibility.

Usability

I got turned on to Jared Spool through a presentation titled “Scent, Search, and the Pursuit of User Happiness”. I’ve been a big fan of his and the work being done at User Interface Engineering (UIE) ever since. Through UIE articles and podcasts, I’ve learned a lot about putting the user (and their goals) at the center of any development process. Their research has made my work better.

Accessibility

Around the same time, I discovered a presentation by Douglas Bowman (I think from the same Web Design World 2005 conference) titled “Create Beautiful Interfaces With CSS”. In this presentation he relayed a story about redesigning the Wired.com. The layout was table-less and used CSS for layout.

What made this story so powerful for me was when he described an email he received, praising the redesign. The sender ended the email with, “by the way, I’m blind”. It turns out that table based layouts play havoc with screen readers and other assistive technologies. I’ve been a big proponent of standards based layouts and CSS since hearing this.

It still amazes me how many commerce web sites are still table based. How much money is lost per year because people have difficulty accessing online services?

More astonishing is the number of charity and non-profit sites that have yet to update their layouts for accessibility.

I Believe...

A recent reorg at my company left me with a new manager - and a different approach to software development than my team had been previously following.  Our new approach is one that I don’t necessarily agree with, but it led me to think about - and reevaluate -  those tenets of software development that I think are important and that I believe lead to increased quality and productivity. This post will consist of fairly high level discussions about how to organize code, teams, and projects - but contain very little actual code. Many of these ideas will not be my own.  They are mostly ideas I’ve learned from others and their willingness to share their experiences with me.  They are, however, ideas that I’ve practiced and hardened as I’ve worked to build my own ideal environment for delivering value through software . Many of these ideas I now take for granted as commonplace (even though they aren’t).  I felt a need to document them anyway - so people can understand what to expect (a

FRail :include

I really like developing with Rails, but I've been frustrated the last few days by some things Rails should do quite easily, yet doesn't. I've already written here and here about some of my struggles with Rails :include clause. Here's one more... Let's say you have a has-and-belongs-to-many relationship. If you :include this relationship in a find query, Rails will automatically create the join clause including the lookup table! That's cool. Unfortunately, it looks as if only the :include clause provides this piece of functionality. Why isn't the same functionality provided via the :join clause or through a general purpose module? This doesn't make any sense to me! I'm working on a database application where I don't need to display a lot of data, but the data displayed is heavily filtered by it's connections to other information in the database. I need to join a lot of tables to perform the filtering operation and using :include

Performance Tuning JCAPS - Part 2

It's been close to 2 months since my first Performance Tuning JCAPS post. Since then, we've noticed our servers running out of TCP connections under heavy load. Researching this problem, we learned that the JCAPS' JMS server makes heavy use of TCP in implementing Request/Reply queues . We approached Sun for guidance and they assured us that they've had success implementing high throughput applications using the JMS request reply solution... but how? It appears a multi-step solution is needed. First, running out of TCP connections in a scenario like ours is a JCAPS bug addressed in an ESR (110348) and rolled into JCAPS 5.1.3 Update Release 3 . We installed this update and noticed a marked improvement. Running my simple 75 user simulated test, transactions took 2521 ms to round trip (compared to the previous time of 20128ms). While this is great improvement, an average of 2.5 seconds is still really slow for this simple transaction. We reported our findings to Su
