Optimizing Development Projects With Multi-Vendor Approaches
Using multiple vendors to develop software, each with their own speciality is becoming increasingly more common. There is much sound logic in the approach. For example: internal resources may generate requirements while a second, offshore organization performs the construction, and a third, a testing specialist tests the work product. The result: often a complete system at reduced cost.
An independent test team is healthy in most circumstances because the testers will probably:
- Not make the same faulty assumptions that may have been made by developers
- Find pride in defect detection (versus developers whose sense of worth may come from development itself, not finding defects),
- Be testing specialists (rather than developers who were made to test)
- Possibly be lower cost per hour than the main development team
SEER-SEM estimates such partial (multi-vendor) projects so stakeholders have a complete picture of the costs, benefits, and schedule considerations. The included figure illustrates several examples of such estimates. Click here to download example SEER-SEM project
Note the upcoming 7.4 release of SEER-SEM includes knowledge bases out of the box for these partial development scenarios. Today, in SEER-SEM 7.3 users may simply define such multi-vendor estimates themselves or ask technical support for assistance.

In my opinion, I don’t think I have encountered a situation in 8 years that I could not represent with SEER for Software in such a fashion that it was readily defendable and logically consistent with what an experienced software engineer would expect (assuming he was honest and not just “preaching the party line”.
