Architecture in 4 Slides

I think Bruce's idea on an Architecture in 4 Slides is the right idea for presenting such material at the executive level. Often times the C-level crowd does not have the time, nor should they take the time, to digest all the details of the full architecture description. At the end of the day, the executive wants to know "how do I get to the future state". This usually means going to the fourth slide that describes the roadmap.

I started doing some math, though, and realized that Bruce was only talking about Enterprise Technology Architecture. For those who think in TOGAFian terms, we have three other domains to describe. And maybe a 4-pack of slides each for security and SOA. So unfortunately the executive deck grows 4 slides at a time. But I think Bruce's idea is still sound. Each domain gets four slides.

I think this approach is good for the boardroom. I think this executive deck is a derivation of more detailed models. Those who need to plan and ultimately implement the architecture need more detail. I've contended in other forums that one picture is insufficient to describe. One needs multiple views of an architecture (segment) in order to fully understand it. Secondly, pictures alone are insufficient. A description of the elements and rationale for decisions made is essential to make the architecture description actionable. I'm thinking of the standard formerly known as IEEE 1471 which advocates for multiple views based on the stakeholder and their concern(s). We the architects need to consider the audience of our work and tune it accordingly. This means multiple versions, levels, of detail, and notations perhaps to make our points.
