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

What is Project Management Life Cycle?

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

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 phase of the cycle is goal-oriented has its own set of characteristics and contains product deliverables, which are reviewed at the end of the Project Management steps.

According to the Project Management Book of Knowledge (PMBOK), the Project Management life cycle should define the following aspects:

  • What work needs to be achieved?
  • Who will be involved in the team?
  • What are the project deliverables?
  • How to monitor the performance of each phase?

Phase-to-Phase Relationships

In cases where projects have two or more phases, the phases are considered part of a sequential process. However, in some situations, the project might benefit from overlapping or concurrent phases. The phase-to-phase relationships can be of two types:

  • Sequential Relationship
    In a sequential relationship, a new phase starts only when the preceding phase is complete. In the figure given below, you can see an example of a project with three entirely sequential phases. The step-by-step nature of this approach decreases uncertainty, but may also remove options for reducing the overall schedule.
  • Overlapping Relationship
    In an overlapping relationship, as the name suggests, the next phase starts before the completion of the previous one. Overlapping phases sometimes need additional resources because work has to be done in parallel. It may increase risk or could lead to rework if a succeeding phase progresses before correct information is gathered from the previous phase.

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.

Adaptive Life Cycles

The adaptive life cycles, also known as change-driven or agile methods, are used in cases of high levels of change or application areas such as IT. Adaptive methods are also iterative and incremental, but the difference is that iterations are very rapid (typically with a duration of 2 to 4 weeks) and are fixed in time and cost. Sometimes the processes within the iterations can be going on in parallel.

5 Phases of Project Management Life Cycle

project phases - invensis learning

1. Project Initiation

Project initiation is the first Project Management life cycle phase, where the project starts. It provides an overview of the project, along with 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 kicks off a meeting to understand the client and stakeholders’ requirements, goals, and objectives. It is essential to go into minute details to have a better understanding of the project. Upon making a final decision to proceed, the project can move on to the next step: that is, 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 feasibility of the project. 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 length, breadth, and depth of the project. 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 have meetings 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 which help to guide your team through the implementation phase and closing phase. The program created at this point will surely help you to manage cost, quality, risk, changes, and time.

The project plan developed should include all the essential details related to the project goals and objectives and should also detail 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 to streamline 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 to monitor the quality level of the project. 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 by keeping the team members focused.

The team involved will start creating 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 among 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 identifies the issues.

2. Hold Regular Meetings

Before you kick off a project meeting, be clear about the agenda and make team members aware of what the meeting is all about well in advance. If communication is timely and straightforward, the productivity of ongoing projects and those that are in the pipeline will not get 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 all about measuring the performance of the project 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. To aid this, a project manager may conduct review meetings and get regular performance reports.

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 phases is equally important.

The project closure phase represents the final phase of the Project Management life cycle, which is 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, it is the role of the project manager 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.

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 life cycle of the project 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 towards 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 kinds of project life cycles but in different ways or to different degrees. The intent of the adaptive life cycles lies particularly with keeping stakeholder influences higher and the costs of changes lower all through 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.
