Risk Management Professional: Prep for the PMI-RMP Exam

The critical path is the longest chain of dependent activities through a project's schedule, which sets the earliest possible finish date and on which any delay delays the whole project.

A Gantt chart is a schedule drawn as horizontal bars against a calendar, one bar per activity, with dependencies drawn between them and progress shown along each bar.

A risk register is the project's living list of things that might happen and would matter, each with an estimate of likelihood and impact, a planned response, an owner and a review date.

A retainer is a recurring fee that holds a supplier's time or availability open across a period, so what the client buys is first call on somebody's attention rather than any named artefact.

A day rate sells a bounded unit of a supplier's working time rather than a finished result, so the client rather than the supplier carries the risk that the job turns out bigger than it looked.

A client brief is the short written statement of what a piece of work has to achieve, for whom, and under which fixed constraints, agreed before either side commits to a solution.
