5 Phases of Project Management Life Cycle You Need to Know

Successful completion of a project is not an easy endeavor. It calls for a series of tasks to meet stakeholder and client requirements; a lot is involved in the project management life cycle process before the project reaches the completion phase.

No matter what type of project you are working on, having comprehensive knowledge about the Project life cycle, project phases, or process groups is essential. It keeps your ongoing projects more organized and viable from ideation to completion.

What is Project Management Life Cycle?

A Project Management life cycle (Process Group) is a five-step framework to assist project managers in successfully completing projects.

The primary competency of a project manager is to gain a thorough understanding of project management stages. Knowledge and planning for the five Project Management steps will help you plan and organize your projects so that it goes off without any hitches.

It is simpler for a project manager to handle all the current details of the project when the project is broken down into various phases. Each cycle phase is goal-oriented, has its own characteristics, and contains product deliverables, which are reviewed at the end of the Project Management steps.

Why Process Groups in Project Management?

For a project to be successful, the project team should:

  1. Determine suitable processes required to meet the project objectives
  2. Work to achieve requirements by using a defined approach
  3. Arrange and maintain appropriate communication and engagement with stakeholders
  4. Comply with requirements to meet stakeholder needs and expectations
  5. Balance the critical constraints of scope, schedule, budget, quality, resources, and risk to produce the particular product, service, or result

The project manager and his team are responsible for deciding which processes are appropriate and how to utilize them to get the best out of the project.

The processes in Project Management are connected and aligned to each other in one way or the other. Modifications and changes performed during one process affect other related processes also. For instance, a change in scope typically affects project cost, but it may not affect the level of risk. These process interactions often require compromises among project requirements and objectives. These adjustments could vary from project to project and organization to organization. The role of a project manager is to manage these interactions to meet sponsor, customer, and other stakeholder needs. Sometimes, a process or set of processes may need to be iterated several times before achieving the required outcome.

Characteristics of a Project Life Cycle

The generic life cycle structure commonly exhibits the following characteristics:

  • At the start, cost and staffing levels are low and reach a peak when the work is in progress. It again starts to drop rapidly as the project begins to halt.
  • The typical cost and staffing curve do not apply to all projects. Considerable expenses secure essential resources early in their life cycle.
  • Risk and uncertainty are at their peak at the beginning of the project. These factors drop over the project’s life cycle as decisions are reached and deliverables are accepted.
  • The ability to affect the final product of the project without impacting the cost drastically is highest at the start of the project and decreases as the project advances toward completion. It is clear from figure 2 that the cost of making new changes and rectifying errors increases as the project approaches completion.

These features are present almost in all project life cycles but in different ways or degrees. The intent of the adaptive life cycles lies particularly with keeping stakeholder influences higher and the costs of changes lower throughout the life cycle than in predictive life cycles.

Let’s take a look at how knowledge of the project life cycle benefits an organization:

  • It helps professional services teams to be more proficient and profitable.
  • The project life cycle helps the organization.
  • It makes the flow of communication easier.
  • The knowledge emphasizes reporting and examining previous projects.

Important Elements of Project Management Process Groups

There are some Project Management processes, apart from the five above, which run through all of the phases:

  • Phase Management: As the name suggests, a project manager’s job is to satisfy the conditions for completing each phase and starting the next one. Before exiting a phase, he must be fully aware of the deliverables that must be completed and accepted by the concerned stakeholders.
  • Communication: Communication plays an integral part in any project. A project manager must ensure that communication responsibilities are clear with team members, the project board, the different stakeholders, and related third parties. Insufficient or improper communication is a common problem area for projects and needs to be appropriately addressed.
  • Procurement: This is a specialist area. Some projects, like the ones involving information technology, hire third parties to manage purchasing or any other department. Efficiently managing these third parties is an essential task for a project manager.
  • Integration: Many projects impact their department or area and other business areas. As a project manager, one must ensure that he reflects on how the project will interface with other projects or functions or affect other businesses.

Predictive Life Cycles

In predictive life cycles, also known as fully plan-driven the three major constraints of the project, the scope, time, and cost, are determined early in the project life cycle. These projects progress through a series of sequential or overlapping phases. Now the planning can be done for the entire project at a detailed level from the beginning of the project. Different work is usually performed in each phase. Therefore, the composition and skills required of the project team may vary from phase to phase.

5 Phases of Project Management Life Cycle

1. Project Initiation

Project initiation is the first Project Management life cycle phase, where the project starts. It provides an overview of the project and the strategies required to attain desired results. It is the phase where the feasibility and business value of the project are determined.

The project manager starts a meeting to understand the client and stakeholders’ requirements, goals, and objectives. It is essential to go into minute details to understand the project better. Upon making a final decision to proceed, the project can move on to the next step: assembling a project team.

The Project Charter is considered to be the most important document of any project as it comprises:

  • Business vision and mission
  • Project goals and benefits
  • List of stakeholders
  • Scope of the Project
  • Project deliverables
  • Risks associated with the project
  • Project budget and resources

1. Undertake a Feasibility Study

In the initial stage, it is essential to understand the project’s feasibility. See if the project is viable from the economic, legal, operational, and technical aspects. Identifying problems will help you analyze whether you can solve issues with appropriate solutions.

2. Identify the Project Scope

Identifying the project scope involves defining the project’s length, breadth, and depth. On the other hand, it’s equally essential to outline functions, deadlines, tasks, features, and services.

3. Identify the Project Deliverable

Upon identifying the project scope, the very next step is to outline the project deliverables. The project deliverables include defining the product or services needed.

4. Identification of Project Stakeholders

A thorough identification of project stakeholders is essential. It is better to meet with team members and experts to identify project stakeholders. Documentation of relevant information on stakeholders and their impact on the successful completion of the project is required.

5. Develop a Business Case

Before developing a business case, check whether the essential pillars of the project such as feasibility, scope, and identification of stakeholders, are in place. The very next step is to come up with a full-fledged business case.

The creation of a statement of work (SoW) and the formation of a team wrap up the project initiation phase.

 2. Project Planning

A lot of planning related to the project takes place during this phase. On defining project objectives, it is time to develop a project plan for everyone to follow.

The planning phase frames a set of plans that help guide your team through the implementation and closing phases. The program created at this point will help you manage cost, quality, risk, changes, and time.

The project plan should include all the essential details related to the project goals and objectives and how to achieve them. It is the most complex phase in which project managers take care of operational requirements, design limitations, and functional requirements.

The project planning phase includes the following components:

Project Planning

1. Creating a Project Plan

A project plan is a blueprint of the entire project. A well-designed project plan should determine the list of activities, the time frame, dependencies, constraints involved, and potential risks. It assists the project manager in streamlining operations to meet the end objective and tracking progress by taking appropriate decisions at the right time.

2. Creating a Resource Plan

The resource plan provides information about various resource levels required to accomplish a project. A well-documented plan specifies the labor and materials to complete a project. Resources used should have relevant Project Management expertise. Experience in the concerned domain is a priority.

3. Budget Estimation

Framing a financial plan helps you to set the budget and deliver project deliverables without exceeding it. The final budget plan lists expenses on material, labor, and equipment. Creating a budget plan will help the team and the project managers to monitor and control the costs throughout the Project Management life cycle.

4. Gathering Resources

Gathering resources is an essential part of project planning as it helps monitor the project’s quality level. It is not enough to assemble a well-balanced team from internal and external resources. Resources like equipment, money, software solutions, and the workplace should be given to complete the assigned tasks.

5. Anticipating Risks and Potential Quality Roadblocks

The risk plan will help you identify risks and mitigate them. It will comprise all the potential risks, the order of severity, and preventive actions to track it. Once threats are under control, it is possible to deliver the project on time, adhering to quality.

3. Project Execution

Project execution is the phase where project-related processes are implemented, tasks are assigned, and resources are allocated. The method also involves building deliverables and satisfying customer requirements. Project managers or team leaders accomplish the task through resource allocation and keeping the team members focused.

The team involved will create project deliverables and seek to achieve project goals and objectives as outlined in the project plan. This phase determines whether your project will succeed or not. The success of the project mainly depends on the project execution phase. The final project deliverable also takes shape during the project execution phase.

There are a lot of essential things that are taken care of during the execution phase. Listed below are a few of them:

Project Execution

1. Reporting Progress of a Project

During the project execution phase, it is essential to get regular project updates as it provides the required information and even identify the issues.

2. Hold Regular Meetings

Before you kick off a project meeting, be clear about the agenda and inform team members of the meeting well in advance. If communication is timely and straightforward, the productivity of ongoing projects and those in the pipeline will not be affected.

3. Manage Problems

Problems within the project are bound to occur. Issues such as time management, quality management, and a weakening in the team’s morale can hinder the success of a project. So make sure all problems are solved in the beginning.

4. Project Monitoring and Control

The project monitoring and control phase is about measuring the project’s performance and tracking progress. It is implemented during the execution phase. The main goal of this phase is to check whether everything aligns with the Project Management Plan, especially concerning financial parameters and timelines.

It is the responsibility of the project manager to make necessary adjustments related to resource allocation and ensure that everything is on track. A project manager may conduct review meetings and get regular performance reports to aid this.

Monitoring project activity after the project execution phase will allow the project manager to take corrective actions. Meanwhile, considering the quality of work will also help to make the necessary improvements. Keeping an eye on the budget will help to avoid unnecessary expenses and resources.

5. Project Closure

With much time and effort invested in project planning, it is often forgotten that the final phase of the Project Management life cycle is equally important.

The project closure phase represents the final phase of the Project Management life cycle, also known as the “follow-up” phase. Around this time, the final product is ready for delivery. Here the main focus of the project manager and the team should be on product release and product delivery. In this stage, all the activities related to the project are wrapped up. The closure phase is not necessarily after a successful completion phase alone. Sometimes a project may have to be closed due to project failure.

Upon project completion and timely delivery to clients, the project manager’s role is to highlight strengths, list the takeaways of the project, identify the ambiguities, and suggest how they could be rectified for future projects. Taking time to recognize the strengths and weaknesses will help to handle projects with more dedication; this, in turn, builds the project manager’s credibility.

Once the product is handed to the customers, the documentation is finalized, the project team is disbanded, and the project is closed.

Types of Project Management Life Cycle

There are several different types of project management life cycles, each with its own set of steps and processes. Some of the most common types include:

  1. Waterfall: This is a linear, sequential approach in which each phase of the project must be completed before moving on to the next. It is often used for projects with well-defined requirements and a clear end goal.
  2. Agile: This is a flexible, iterative approach that emphasizes rapid development and continuous improvement. It is often used for projects with rapidly changing requirements or unclear end goals.
  3. Iterative: This is a cyclical approach that involves repeating the project life cycle multiple times in order to refine and improve the project. It is often used for projects with complex requirements or a high level of uncertainty.
  4. Hybrid: This approach combines elements of two or more project management life cycle types. It is often used for projects that have characteristics of different types of projects and require a tailored approach.
  5. Lean: This approach is based on the principles of Lean manufacturing, it emphasizes on reducing waste, maximizing value, and empowering the team.
  6. Kanban: This approach is a scheduling system for lean manufacturing and just-in-time manufacturing (JIT). Kanban is a visual process-management system that tells team members what to produce, when to produce it, and how much to produce.

Each type of project management life cycle has its own set of advantages and disadvantages, so it’s important to choose the right one for your specific project.

IT Industry

The project management lifecycle in this industry includes the phases of initiation, planning, execution, monitoring and controlling, and closing. This process involves coordinating the efforts of IT professionals, such as network administrators, software developers, and IT managers, to design, implement, and maintain IT systems and infrastructure.

The project life cycle can vary depending on the industry and the specific project. Still, these examples give you an idea of the stages and activities typically included in different projects.

Project Management Lifecycle example

One example of a project management lifecycle case study is the construction of a new hospital.

  1. Initiation: The project is initiated by the hospital board, which identifies the need for a new facility to meet the community’s growing healthcare needs. A project manager is appointed to lead the project, and a project charter is developed outlining the project’s objectives, scope, and stakeholders.
  2. Planning: The project manager works with architects and engineers to design the new hospital, considering factors such as patient flow, medical equipment needs, and building codes. A detailed project plan is developed outlining the schedule, budget, and resources required for the project.
  3. Execution: The project manager coordinates the efforts of the construction team, including workers, subcontractors, and suppliers, to build the new hospital. Regular progress meetings are held to ensure the project stays on schedule and within budget.
  4. Monitoring and Controlling: The project manager closely monitors the project’s progress and makes adjustments as necessary to keep the project on track. This includes identifying and addressing any risks or issues that may arise.
  5. Closing: The project manager reviews the project to ensure that all objectives have been met and that the new hospital is ready for operation. The project is formally closed, and the project team is disbanded.

Throughout the project, the project manager communicates regularly with the hospital board and other stakeholders to keep them informed of the project’s progress and to address any concerns they may have.


It’s vital that professional project managers are familiar with the practice and execution of five main process groups. The only way to make oneself most worthy or valuable to a company is to know how one can effectively initiate, plan, execute, monitor, and close a project. As the project manager undertakes and leads more projects, he/she gains enough experience which is necessary to understand what works best for the progress and growth of the company.
