Six Things I Think I Think About UIs

Computerworld - Software without a good user interface is -- well, it's useless. Unfortunately, UIs aren't nearly as well understood as more objective "speeds and feeds" kinds of product characteristics. Products with snazzy demos often prove disappointing in real life. Meanwhile, truly good UIs are hard to explain beyond an "I know it when I see it" vagueness. But difficulty notwithstanding, UIs are too important not to write about. And so, to steal a line from sportswriter Peter King, here are six things I think I think about UIs.

1. A good graphical user interface is the most important feature a product can have. In many cases, the GUI is the feature set, whether we're talking about operational applications, business intelligence or IT administration tools. For example, the general user analytics market is dominated by friendly BI tools. More powerful products exist, but they're mainly used by specialists, since everybody else is turned off by their clunky GUIs or command-line interfaces.

Equally dramatic is the importance of GUIs in IT administration. Check Point Software Technologies rose to dominate the firewall market because it offered a usable administrative GUI back when other products operated from command lines. Similar phenomena occurred in database administration tools, network administration and many other sectors -- and would occur in more sectors if vendors would wise up. (I've been nagging the BI industry for years about developing a stronger capability to manage alerts and custom key performance indicators.)

2. Web UIs are now, finally, much superior to the client/server systems they replaced. Usually, changes in computing platforms lead to improved user interfaces. More powerful mainframes and cheaper minicomputers allowed real-time apps to replace batch systems in the 1980s. Client/server GUIs blew out character-based apps in the 1990s. For years, Web technology was a partial exception, since it actually caused a retreat in GUI flexibility. But the group of technologies collectively labeled AJAX, has finally restored client-side parity -- or, if you like multimedia, even forged ahead -- and Web apps now boast top-tier GUI functionality. What's more, they have major application navigation advantages, via hyperlinking and search, over anything that came before.

3. BI look and feel is on the upswing. One UI area that stagnated for years was BI. Not only was it hit by the transition from client/server to the Web, but vendors also spent years upgrading their server-side infrastructures. Now, however, we're beginning to see UI advances again. Some of them are subtle, such as the care being taken to optimize the use of screen real estate. Others are flashy, such as the long-overdue mainstreaming of some cool data- visualization technologies. Either way, UI is once again an important decision factor in selecting a BI vendor.
