Trap: Use the same person as the PM and the architect
Using the same person as the project manager and the architect will work only on small projects (5-10 peopole). For larger endeavors, having the same person play the role of both project manager and architect will usually end with the project neither properly managed, nor well architectured.
First, the roles require different skill sets.
Secondely, the roles in and of themselves, are more than a full-time job.
...
When the same person plays the same two roles, the project rarely succeeds.
