Case selection

To investigate the phenomenon of engagement I need a collection of instrumental case studies. It would be nice to have a formal sample, because I might expect that such samples would represent some population of cases {Stake, 2005 #1371}. But the sample size I have is "too small to warrant random selection". So I have a purposive sample instead, a variety that represents different types of organisation, different IT projects and different types of third parties (consultants, suppliers, contractors). So I've chosen cases that seem to offer opportunities to learn and because these cases are accessible.

The other thing my cases seem to have in common is something successful about them - the participants are proud of their work.
