The ratings are based on six different criteria
- IT Vision - What are they going to do in IT, implementation of applications, integration with backends, sort of the technical end of SOA
- IT Implementation - Great powerpoints guys, but what about the products...
- Business Vision - What are the doing for the business, what is the content and how will it work for the business
- Business Implementation - as before, what exists beyond the powerpoints
- Standards - SOA implementation is massively about standards, how much does this company implement and drive standards
- Stability - How stable is the current product set and roadmap, will they be shifting strategy and leaving you in the lurch, or going out of business and doing the same
So to start with, and with six criteria, I've gone for six companies. IBM, SAP, Oracle, Microsoft, BEA and Sun. So how do they rate?
Bit hard to read on one diagram I know, so here is a quick over view with the pictures for each of the companies broken out.
So that is how I see it right now with these six vendors, I'll start having a hands on and eval around the other products out there (any requests appreciated), and also what would be a sensible sectorisation of the SOA marketplace to see who really plays where and what are the biggest gaps (e.g. nobody really does Business modeling, only Microsoft have made an attempt).
