It all depends on the situation and there are many scenarios. Scenario 1: if past variance (performance) is expected to continue (good or bad) then we can expect there will be a CPI (Cost Performance Index) for the work done to date.

Project Management Questions

I've never (officially) used a baseline survey myself and all my projects went OK without it. I personally don't know of any other project manager (and I know many) who uses a baseline survey. I also think that the definition of a baseline survey is not consistent especially when it comes to project management. It is also not defined in the PMBOK.

In other words, the project manager has to explain to the team members why the company is undertaking this project and how it will (positively) affect them when it's done. - Constantly praising team members who are obviously not happy with their tasks, this will alleviate some of the pressure off their shoulders, and will somewhat clear the air.
