Putting all pitfalls together in one simple 10 item list quickly reveals a grouping of types pitfalls. Number #1 and #2 are both related to organizational aspect. If the culture, mindset and attitude are not right, these are typically the pitfalls that a SOA endeavor may run in to. The next group covers the items #3 till #7, these are all related to architectural/design skills. And the last group, numbers #8 till #10, relates to implementation issues (although proper design could help to prevent these pitfalls from manifesting themselves).
The complete Top 10 SOA pitfalls list is:
- #7 - Incorrect Granularity of Services
- #6 - SOA does not solve complexity automatically
- #5 - Big Design Upfront
- #4 - Incorrectly applied Canonical Data Model
- #3 - Missing skills
It was great fun to compile this list with the four of us and it also helped us to get a sharper view on why SOA projects or programs are challenging and hard to complete succesfully. Hopefully you've learned a thing or two and are able to prevent or at least recognize the pitfalls in your day-to-day work.
