Project Life Cycle Phases

The main purpose of a successfull project management team is to complete the project on time and budget with meeting the customer’s requirements and the project’s objectives. Typically, every project has a beginning, an execution and a closing phase and all the phases involve several processes and tasks such as defining scope, creating baseline schedule, measuring project’s performance etc. Typically, project life cyle phases create a roadmap to organize and manage any type of project  successfully. Therefore these phases are essential for all the project managers aim for completing projects effectively. In this article we will review five project life cycle phases.

What are the Five Project Life Cycle Phases ?

Project life cycle phases may vary from one project to another depending on the requirements. However, below phases can be recommended for project management.

Phase 1: The Initiation Phase

Phase 2: The Planning Phase

Phase 3: The Implementation (Execution) Phase

Phase 4: The Controlling Phase

Phase 5: The Closing Phase

1. The Initiation Phase

The Initiation phase is the first phase of project management life cycle. The product or the project is described, it’s objectives and requirements are specified during the initiation phase. A feasibility report may be created to understand whether the project is feasible or not. The aim of creating a feasibility report is to analyze the project objective, specify the solutions, highlight the opportunities and promote decision making processes. Project deliverables, financial benefits and the incomes are decided by the important stakeholders in this phase. If the project idea is adobted by the important stakeholders, the project manager creates the project charter.

2. The Planning Phase

The Planning phase is one of the most important phase of a project lifecyle. It is directly related with the success of the project. At this phase, project scope is defined and the project management plan is created. The project manager creates several project management documents including but not limited to the following;

Scope Statement
– WBS (Work Breakdown Structure)
Baseline Schedule
Baseline Budget
Risk Management Plan

After defining the project scope and key milestones clearly, WBS (Work Breakdown Structure) is created to divide and manage the project’s scope into meaningful sections. After that baseline schedule is prepared to create a roadmap for the projects objectives. Baseline budget , Risk Management Plan and other supporting documents, plans and procedures are created based on the targets emphasized in the scope statement. The project manager prepares risk management plan to identifiy the risks and estimate their impacts to the successfull completion of the project.

During the planning phase, stakeholders are analyzed, identified and classified according to their power, influence and effects on the project. Various models can be used to classify stakeholders according to the project’s requirements.

Beyond these, communication plans, quality plans, quality assurance plans, integration management plans, change management plans can be created during the planning phase.

3. The Implementation (Execution) Phase

The implementation phase comes into action after the planning phase. A kick-off meeting can be considered as a start milestone of the implementation phase. All the materials, sub contractors, manpower and various resources are organized to perform the activities. Execution phase includes to perform all the tasks and build the deliverables required to complete the project and satisfy the customer. Team is created, team responsibilities are specified, resources are allocated, status meetings are assembled and the project schedule is updated as the work performed at this step.

During the implementation phase project management activities are performed including but not limited to the following.

– Creating the Project Management Team

– Creating OBS (Organization Breakdown Structure)

– Assigning Responsibilities

– Resource Allocation

Procurement Management

– Contract and Claim Management

– Project Execution

– Updating Project Schedule and Project Plan if needed.

4. The Controlling Phase

Project performance is measured and conrtrolled at this step. Work performance reports are created in order to determine the cost and schedule variances. Baseline schedule is compared with the updated schedule and the variances are reported. In the same way baseline budget is compared with the actual budget and cost variances are calculated. Quality performance, risk status, and other related important forecasts and issues are controlled and reported at this step.

5. The Closing Phase

Project closing process is completed after completion of all the scope of work and the project management processes. A formal agreement is reqired between the contractor and the customer. A set of formal processes should be completed before prior to the closure.


In this article we reviewed Project Life Cycle Phases. Basically, the initiation phase describes the project and specifies it’s objectives. The planning phase defines the key milestones, project scope , WBS (Work Breakdown Structure) and other related important project management documents. Baseline budget and baseline schedule is created at this step. The implementation phase involves all tasks required to build the product. The controlling phase includes performance measurement and project control processes and the closing phase includes all the processes and formal agreement required to close up the project.

However projects life cycle phases may vary from project to project, industry to industry. In some projects and industries these phases may be combined considering the project’s requirements. The project management life cycle is an important concept of project management. Therefore it will be usefull to know Five project life cycle phases for a successful project management.
