Sorry, I should mention that I’m a bit behind the curve in terms of tracking estimates vs actuals in terms of time. In some ways though, it does not matter, better to value price the work then set deadlines/benchmark dates for your staff and let them figure out how to hit the deadlines. If your staff is on salary, the only point to time tracking is to have a database of time req’d for past jobs to refer to when pricing new jobs. If you decouple time tracking from profitability you stop putting your thumb on your employees, give them the tools to hit the deadlines and destress yourself from worrying about time. Efficiency should be about profitability, not about time.
