It's a good idea to keep records and charts regarding the people on a project team. You'll want to keep a Human Resources Assessment, a Skills Inventory worksheet, and a Responsibility Assignment document as well.
The Human Resources Assessment template, illustrated below, allows you to perform a basic assessment of each of your team members to identify their skills. You can use a scorecard rating of N = Neophyte, J = Junior, S = Senior for their experience level, or simply key in some text describing their experience. Note that you might have to fill out this matrix by visiting with the supervisors of the various team members on the matrix.
Similarly, the Skills Inventory worksheet, illustrated here, will allow you to assess the education, training, and certifications of your various team members.
The Responsibility Assignments document, allows you to note a task, and then fill in the team members that will be working on that task. The legend provides a way for you to describe the level of involvement in a percentage of his or her time for a particular person.
