Todd Biske: Outside the Box

While I didn’t attend the later session on it, in the opening keynote of the AADI Summit on Monday, the term “Context-Oriented Architecture” was mentioned. A colleague (thanks Craig!) caught me in the hall and asked me what my thoughts were on it, and as usual, my brain starting noodling away and the end result was me leaving the conversation saying, “you’ll see a blog entry on this very soon!”

I’ve brought up the slides from the Gartner session on it, and they estimate that sometime in the 2010’s, we will enter the “Era of Context” where important factors are presence, mobility, web 2.0 concepts, and social computing. The slides contain a new long acronym, WYNIWYG (Winnie Wig?), which stands for “What You Need is What You Get.” While it seems that the Gartner slides emphasize the importance that mobility will have in this paradigm, I’d like to bring it back into the enterprise context. While mobility is very important, there is still a huge need for WYNIWYG concepts in the desktop context. There will be no shortage of workers who still commute to the office building each day with the computer in their cube or their desktop being their primary point of interaction with the technology systems.

I think the WYNIWYG acronym captures the goal: what you need is what you get. The notion of context, however, implies that what you need changes frequently within a given day. Keith Harrison-Broninski, in his book Human Interactions, discusses how a lot of what we do is driven by the role we are playing at that point in time. If we take on multiple roles during the course of our day, shouldn’t we have context-sensitive interfaces that reflect this? If you’re asking the question, “Isn’t this the same thing as the personalization wave that went in (and out?) with web portals?” I want to make a distinction. Context-sensitivity has to be about productivity gains, not necessarily about user satisfaction gains. Allowing a user to put a “skin” on something or other look and feel tweaks may increase their overall level of satisfaction, but it may not make them any more productivity (I’m not implying that look and feel was the only thing that the personalization wave was about, but there was certainly a lot of it). As a better example of context-sensitivity, I point to the notion of Virtual Desktops. This has been around since the days of X Windows, with the most recent incarnation of it being Apple’s Spaces technology within Leopard. With this approach, I can put certain windows on “Virtual desktops” rather than have all of them clutter up a single desktop. With a keystroke, I can switch between them. So, a typical developer may have one “desktop” that has Eclipse open and maximized, and another “desktop” that has Outlook or your favorite mail client of choice, etc. Putting them all in one creates clutter, and the potential for interruptions and productivity losses when I need to shift (i.e. context-shift) from coding to responding to email.

Taking this beyond the developer, I bring in the advent of BPM and Workflow technologies. I’ve blogged previously on how I think this will create a need for very lightweight, specific-purpose user interfaces. Going a step further, these entry points should all be context-sensitivie. I’m doing this particular task, because I’m currently playing this role. Therefore, somehow, I need to have an association between a task and a role, and the task manager on my desktop needs to be able to interact with the user interaction container (not any one specific user interface, but rather a collection of interfaces) in a context-sensitive manner to present what I need. In our discussion, he brought up an example of an employee directory. An employee directory itself probably doesn’t need to be context aware. What does need to be context-aware is the presence or lack thereof of the employee directory depending on the role I’m currently playing. Therefore, it’s the UI container that must be context-sensitive.

All in all, this was a very interesting discussion. In looking at the Gartner slides, I definitely agree that this is a 2010+ sort of thing, but if you’re in a position to jump out (way) ahead of the curve, there’s probably some good productivity gains waiting to be had. I recommend getting pretty comfortable with your utilization of BPM technology first, and then moving on to this “era of context.”
