"Dark side" of the contract. Look from the customer
When we work at "the light side" (in the IT companies, outsourcers, integrators), we consider that customers don't know that want, specially tighten the solution of questions and want for few money too much.
I will tell how it looks from one of "dark sides". Why "all so slowly and difficult". As performers in the opinion of the customer look. What mistakes from managers and team of the performer meet most often and as to avoid them.
