A question on LinkedIn recently reminded me that, as the team leader for Segment Architecture in my former EA team, I was accountable for identifying a core set of deliverables for the team. The idea was that we could focus on defining standard formats and contents for these deliverables and, in doing so, we could start to measure both our output and our quality.
We only created pre-canned templates for a few of them. This is partly because the team was not mature enough in its practices to get consistency, and partly because Enterprise Architecture itself is not mature, or accepted, enough to have stakeholders that would notice if our deliverables meet an objective standard. Also this list is not intended to be comprehensive. The goal was to describe deliverables where it may possibly make sense to go for some level of consistency. Any EA could (and often did) create deliverables that were not on the list.
Perhaps it is time to share what we came up with.
