As project managers, most of us have experienced problems on projects. Most of us have also received help (that seemed more like interference) from concerned colleagues and superiors. Back-seat driving, nit picking, hindsight memos -- none welcome, none helpful. There is, however, an alternative. Let's start with the usual "help" and move onto something that is helpful.

nit: noun, the egg or young of a parasite insect.

nit picking: verb, inspecting someone closely for the presence of nits and then picking them off.
