This Microsoft Project add-on provides an improved and important analysis of the critical issues in a project plan. The Critical Chain identifies the critical path of a project based on both time and resource constrains, vs. the report based on time constraint alone! By changing the report's parameters the user can also identify future possible critical pats, thus analyze not only current status, but also have deeper understanding of future risks. If you manage resources as part of your project plan, than Critical Chain is the tool for you!
