Understanding the 5 Essential Phases of the Project Management Life Cycle

The project management life cycle provides a structure for managing all aspects of a project from start to finish. Breaking the cycle down into five phases enables project managers to lead, plan and deliver projects effectively to achieve desired outcomes. This article explores the key phases in detail so you can confidently manage projects. 

Why Follow the Project Management Life Cycle?

The project management life cycle serves as a valuable framework when executing projects in any industry. It outlines the major process groups needed to practice effective project management and take projects from conception through to completion. Structuring your project using the project life cycle phases promotes visibility, accountability and coordination across the team. It also ensures the necessary steps are completed at the right times to realize success. Understanding the methodology helps project managers - whether beginners or experts - carry out projects systematically through each phase. Ultimately, leveraging the project life cycle leads to higher quality project outcomes achieved more efficiently.

What are the 5 High-Level Phases of the Project Life Cycle?

The 5 overarching phases that make up the project management life cycle are:

1. Initiation 

2. Planning

3. Execution

4. Monitoring and Controlling

5. Closure

Let’s explore each of these phases and key activities involved in further detail.

Phase 1: Initiation

What happens during project initiation?

The initiation phase signifies the formal start of a project. It's about defining key information upfront before detailed planning begins.

During initiation, the project manager works with stakeholders, subject matter experts and other contributors to frame project objectives, scope, costs and timelines at a high level along with risks, assumptions and constraints.

What are the key deliverables of this phase?

Main deliverables from the initiation phase include:

• Project charter: Documents high level information about the project goals, timeline, budget, resources, risks and approvals required. It formally authorizes the project.

• Preliminary scope statement: Outlines key objectives, deliverables, constraints and boundaries of the project.

• Business case: Captures the rationale and expected business benefits used to justify initiating the project such as increased revenue, decreased costs or improved services.

What role does the project manager play during initiation?

The project manager spearheads key activities in the initiation phase including:

• Identifying the need or demand for the project from customers and stakeholders

• Defining and documenting project goals aligned to business objectives

• Assessing feasibility of the project given constraints

• Determining level of executive sponsorship and getting buy-in

• Establishing the project team roles

• Developing rough order of magnitude estimates for budget and timing

Careful initiation activities set the stage for the planning phase to build on.

Phase 2: Project Planning

Why is planning vital to project success?

The planning phase represents a critical juncture in the project where a clear roadmap is created for how objectives will be achieved before execution starts. Thorough planning improves ability to manage projects effectively throughout subsequent phases. It helps coordinate tasks, resources and stakeholder involvement optimally. Planning allows project managers to map scope, timing, costs, quality, staffing, procurement and other aspects in detail.

What are key activities involved in project planning?

Major activities that occur during this phase include:

• Defining precise project requirements and scope: All components of the project deliverables and work involved are clearly delineated.

• Creating a project management plan: This comprehensive plan captures how the project will be executed, monitored, controlled and closed out. It houses the schedule, budget, quality plan, risk management plan, staffing plan, communications matrix and all other subsidiary plans.

• Developing a work breakdown structure (WBS): The WBS provides granular definition of each project task or activity needed to fulfill the end product.

• Establishing the project schedule and budget: Detailed timelines and costs are developed during this activity based on the work scope.  

What are the main planning phase deliverables?

Key deliverables from the planning phase include:

• Approved project management plan

• Requirements documentation

• Resource management plan

• Detailed project schedule

• Cost baseline and budget

• Procurement plan

• Quality management plan

• Change management plan

• Risk management plan

• Staffing management plan

• Communications matrix

Having all planning components meticulously prepared allows smooth execution.

Phase 3: Project Execution

What takes place during project execution?

The execution phase focuses on completing project deliverables and fulfilling the work as outlined in the project management plan. The project manager and team perform defined activities, allocate resources, manage vendors, and report status during execution. Most resources, time and money are spent on the project during this phase as the products or services are created.

What is the role of a project manager in execution?

The project manager puts project plans into motion and leads the team during execution. Their oversight role includes:  

• Guiding and managing the team to complete assignments

• Tracking activity progress against the schedule

• Driving tasks towards milestones

• Managing changes using change control processes

• Updating stakeholders regularly on status  

What factors lead to successful execution and delivery?

Factors enabling effective execution and ultimate project success include:

• Detailed project plans: Having meticulous project plans containing all baselines and subsidiary plans allows smooth implementation.

• Resource availability: Ensuring resources outlined in the resource management plan are actually available as needed is vital.

• Executing tasks methodically: Completing work packages using defined procedures, quality standards and acceptance criteria results in quality deliverables. 

• Proactive communication: Keeping the team, sponsors and stakeholders consistently updated prevents surprises and issues.

• Change control: Effectively managing change through documented change control processes avoids negative impacts on the project.

Mastering execution delivers project objectives.

Phase 4: Monitoring and Controlling

Why actively monitor and control projects?

The monitoring and controlling phase oversees project progress to guarantee it stays on track according to plan. This oversight is essential because it:  

• Enables deviations from the baseline to be spotted early 

• Allows preventive or corrective actions to be taken in a timely manner

• Improves accountability through ongoing tracking and measurement

• Provides key status updates to keep stakeholders informed

• Helps contain overall risk 

Careful monitoring combined with appropriate adjustments steers the project successfully towards desired outcomes.

What activities are involved?

Major actions performed in this phase include:

• Measuring project performance such as schedule progress and budget expenditure  

• Managing variances by comparing progress to baselines

• Verifying project deliverables meet defined acceptance criteria  

• Updating project documentation such as status reports, issues logs, risk registers etc.

• Implementing corrective actions where needed to remedy problems

• Managing scope changes through change control processes

• Controlling procurements from vendors and suppliers 

What common tools and techniques help monitor and control projects?

Useful tools leveraged include: 

• Project tracking software to monitor key metrics 

• Written status reports detailing up to date progress

• Scheduled project team meetings and steering committee updates  

• Change control logs to assess impact of proposed changes

• Risk monitoring through risk reassessment

These tools facilitate oversight needed to keep projects on track.

Executing rigorous monitoring and control until the end enables project success.

Phase 5: Project Closure

Why properly close out projects?

The project closure phase focuses on formally wrapping up the project and team’s involvement. It verifies project objectives defined in the charter were met. Closure provides that important opportunity to recap lessons learned, ensure knowledge transfer occurs, celebrate wins, recognize team members for their efforts, archive documents, and close contracts.

What activities happen in closure?

Typical closure activities include: 

• Obtaining final acceptance: Seek formal sign-off from project sponsors and key stakeholders indicating deliverables align to expectations documented in the project charter.  

• Transferring products: Hand over end products to the appropriate groups providing ongoing operations and maintenance.

• Reassigning resources: Release resources from the project so they can be allocated to new initiatives. This starts with notifying team members their project work is ending.  

• Closing supplier agreements: Finalize payments and close contracts for any vendors or suppliers that provided goods or services during execution.

• Conducting post-project review: Perform assessment to identify best practices and improvement actions for future projects based on insights uncovered.

• Archiving project documents: Gather and store all final project documents in accordance with corporate policies related to records retention.

What are common closure phase deliverables?

• Signed project acceptance form

• Completed punch list

• Final procurement audits  

• Post-project evaluation report

• Lessons learned documentation

• transferred project products and archived project documents

Bringing rigorous closure provides that valuable opportunity to learn from the project experience.
