The Project Life Cycle

Project management life cycle

According to the Project Management Body of Knowledge, the foundation of project management rests upon the five phases that every project goes through:

  1. Initiating.  The tasks required to authorize, fund and define the project, generally on the organizational level (above the project).  The organization defines a business need and commissions the project to meet it.
  2. Planning.  The project management team define how the project will be carried out, who will do the work, how long it will take, and so forth.  The planning phase defines the project in sufficient detail that all stakeholders’ expectations are understood.
  3. Execution.  The project work is completed and the end product or service is achieved while secondary stakeholder requirements are satisfied.
  4. Monitoring & Controlling.  Concurrent to the project work (execution phase) the project management team monitors and controls all aspects of the project – schedule, cost, stakeholder’s requirements, etc.  If problems are encountered, changes to the project plan are made.
  5. Closing.  The project has completed it’s product or service, and the necessary documentation and adminstrative work must be done to close the project.

Just to make it sound more complicated than it is, these phases are also called process groups, but I will try to use the term phase wherever possible.

In each phase, one or more project management documents are created.  These consist of:

Phase Project Documents
Initiating
  • Project Charter
Planning
  • Project Management Plan
Execution
  • Status Updates
  • Stakeholder Communications
Monitoring
  • Earned Value analysis
  • Project change documentation
Closing
  • Final reporting

The planning group is by far the largest within the PMBOK, and is the most intensive for the project manager, although the execution phase is the most intensive for the project team.  It contains more than half of the processes even though it is only one out of five process groups.  The project management plan that is generated during the planning phase encompasses all of the knowledge areas, and it should be scaled to the size of the project.

Project Initiation

This process group includes the basic groundwork necessary to create the project and define the guidelines and criteria under which it will operate.  Authorizations from the performing organization are given and funding is put in place.  An initial scope statement can be made, because executives generally have an idea what the project should accomplish when they authorize it.  Any initial project boundaries are determined and stakeholders identified.

This phase produces a document called a Project Charter.  This document contains the relevant project authorization and funding information, as well as scope statements and the like, to get the project going.

Project Planning

Upon authorization of the project, the project must be planned.  This phase is usually the most underrated and underutilized.  Planning is the most intense part of the project management process, because a lack of planning can result in cost and schedule overruns, as well as other project changes which look bad on the project manager and sponsor.  Because of the potential for problems, it is important that the project manager carefully follows each item in the knowledge areas for the project planning phase.

This phase produces a document called a Project Management Plan.  This is the master planning document which establishes stakeholder expectations and makes it clear how the project will be managed.  In the PMBOK, all ten knowledge areas are well served within the planning phase.  It should outline the project’s scope, cost, deadlines, milestones, communication needs, and anything else that shows the stakeholders how the project will be managed.  It is highly specific to individual industries and organizations.  It should be distributed to the major project stakeholders, including the project sponsor.

Project Execution

The execution of the project requires coordination of human resources, managing stakeholder expectations, and dealing with project changes.  The project manager must be on top of issues that arise, as well as making regular forecasts of future schedule and cost problems to deal with changes as far in advance as possible.  Change requests must be handled and documented throughout this phase, and stakeholders must be kept informed.

During the project execution phase, most of the technical work gets done.  Status updates and other project communications are sent to the relevant stakeholders according to the project management plan.  Documents are stored and archived, and stakeholders are managed according to the plan.

Monitoring and Controlling

Throughout the project, the project manager must monitor and control the project work to ensure that project deliverables are on time, on budget and of acceptable quality.  Also, stakeholders must be kept satisfied and the project team must be kept motivated and coherent.  Monitoring and Controlling the project work occurs concurrently to the Execution phase, therefore the two Process Groups occur in parallel.

Tracking of time (deadlines, milestones, etc.) and cost are most commonly done via Earned Value Analysis, which provides a strong early warning of schedule and cost variances.  Quality of deliverables, stakeholder communication, and high risk potential problems are other areas of regular monitoring.  At any time, monitoring can result in changes to the project.

If changes are required to any part of the project as documented in the project management plan, they need to be documented and result in an updated plan.  This includes changes to deadlines, costs, deliverables, and any other change to the project as envisioned.

Project Closing

As underrated phases go, Closing comes in a close second to Planning.  There are almost always a handful of tasks involved in closing the project and moving on, and they are usually high on the visibility scale to executives and project sponsors.  Contractual obligations must be completed and contracts closed, final details submitted, and funding requirements finalized.
