What is to be said of the personal rapport and trust that a client develops with the actual fellows handling their job and with whom they are in constant contact in the course of performance? Does this count for anything?
If it does, is it in order to then require the client to start developing new relationships with new people when the employees leave, yet the self-same employees are capable of performing/implementing the project as originally envisioned?
Life is like playing a violin solo in public and learning the instrument as one goes on.
