Project Life Cycle and PMI Project Management Processes (#5 in the series PMI Project Life Cycle)
By Brian Denis Egan, B.Sc, M.Sc., M.B.A., PMP – Global Knowledge Course Director

As explained, the project life cycle has five stages (initiate, plan, execute, control and close). The PMI refers to these stages as “process groups” for reasons that will be explained.

In order to understand project management according to PMI, it is necessary to understand the boundaries between the project-life-cycle stages or process groups. For example, it is necessary to know when initiating is over and what documents must be ready in order to begin execution.

In order to understand the boundaries between the stages, it is necessary to know what management activities (called processes) are included within each of the stages (called process groups).

The five stages in the project life cycle are subdivided by PMI into 44 management processes as illustrated in the table below. Each column represents a stage. Within each column are a number of management activities that PMI refers to as processes.
