In his post, The Secret Life of CEP, Tim Bass is unimpressed by the claim that CEP vendors have dozens of unnamed customers doing unspecified things.
Twelve paying customers may not be much to boast about. For most new software tools, a typical breakdown would be as follows. Three of the companies are doing small pilot studies, three of them have finished the pilot and don't know what to do next, two of them have started a high risk project with little chance of delivering before 2027, three of them have been distracted by some other shiny new tool, and the one remaining company might possibly be using your tool on serious and achievable projects. Is CEP doing better than this? I think we should be told.
