Research Work

The task is to find information about a specific market segment in the area of project-management. What kind of tools are there available (free / with charge) for teams to allocate the single tasks most efficiently to the person, that can accomplish tha task in the best and fastest way? What are the Methods behind these tools? How many users do they have? Who uses them? I would need a comprehensive study, that lays emphasis on single tools in this segment, but information about bigger software packages which include such functionalities can not be left aside. BUDGET: $5 dont bid if you put higher amount.
