EA exercises involve collecting a lot of data and distilling insights from them. It seems wasteful if the fruits of these efforts are used just once and then thrown away. Instead, when collecting data and doing analysis on them, it is useful to think about how the data and analysis can be re-used.
Specifically, as discussed in Heuristics #2: Guess, Validate, Iterate: Time-bound architectural efforts, the insights are likely to contain some inaccuracies, so expect gradual refinement of the data and analysis. To do that, how the analysis is derived from the data should be clear. In addition, involve as much as possible the people who are going to update it in the future. The more familiar they are with the collected data and analysis, the more likely they will reuse it in the future.
During our EA exercise, we created a chart showing the key products offered by the organization, along with each product’s importance and satisfaction level. We created a first draft of the chart, then we explained to the organization how we did it, and then they refined it. We hope that they will reuse this chart, and we are more confident of it since they have already updated it once. In addition, when we created the summary of our key findings, we tried as much as we can to resist the temptation of listing down gut feels and focus on findings that are backed up by data.
