Pros
Extensive information sharing between various employees at different locations, which will help greatly in starting on a new project in a new area. I can vouch for this from my personal experience because I had to start on a project that was located in a new geographical area that required application of procedures that were different from what I had been used to before I joined Jacobs. There was a lot of help from within the company to guide me with the initial stages of the project - and the time the employees spent on my project was not even billed!! High focus on safety of employees.
Cons
Bureaucracy. It takes forever for each decision to go all the way to HQ and come back. It took almost three months for a simple decision to be made about a software that cost less than $2000, to go all the way to HQ in California and get back. There is way too much red tape to be passed before any conceivable results can be achieved. The adjustment process from Jacob's recent acquisition of Carter-Burgess is still underway, and it is obvious that the folks at Carter and Burgess are not extremely pleased with the way this acquisition went at all.
