Complex projects are broad in scope, resource-intensive, and of significant strategic importance. Managing them demands a higher level of project management expertise.
The Project Management Institute (PMI) developed the project management life cycle as a practical aid. It is a framework designed to guide project managers in running their projects smoothly and effectively.
For project managers, the life cycle brings greater cohesion to the project, ensuring all team members – especially those from multiple departments – are aligned and can collaborate with relative ease.
Here’s how it works.
This post covers:
What is the project life cycle?
The project life cycle defines the steps project managers follow to take a project from inception through to completion.
A defined project life cycle provides a systematic approach to managing projects. It helps project managers execute their projects smoothly and efficiently – fostering cohesion among team members and ensuring all departments involved remain aligned. By breaking the project down into manageable phases, the life cycle enables better monitoring, keeping the project on schedule and within the allocated budget.
This structured progression is essential for turning strategic goals into successful project outcomes. The framework’s value lies in its ability to provide a clear roadmap – enabling more effective control over project variables, better resource allocation, and proactive risk management. Ultimately, understanding and applying a project’s life cycle are key factors in determining project success.
The project life cycle comprises five phases. Each phase represents a group of interrelated processes that must be completed for the project to succeed.
What are the five stages of the project management life cycle?
The project lifecycle comprises five stages:
- Initiating
- Planning
- Executing
- Monitoring and Controlling
- Closing
Initiating phase
The initiating phase of the project life cycle consists of two separate processes – the project charter and the stakeholder register. This phase involves determining the vision for your project, documenting what you hope to accomplish through a business case, and securing approvals from the sanctioning stakeholder.
The key components of the project charter include:
- Business case
- Project scope
- Deliverables
- Objectives
- Resources needed
- Milestone plan and timeline
- Cost estimate
- Risks and issues
- Dependencies
Clearly defining your goals and objectives at the outset makes the project easier to manage. All stakeholders can raise their suggestions or concerns, and the budget and costs can be agreed and signed off. This initiating phase is essential – not only for the project itself, but to ensure all the teams involved have a voice in determining what is needed for its success.
Planning phase
During the planning phase, it is essential to outline and define the rationale for the project. Answering the following questions will clarify what the project needs to achieve:
- What are we going to do?
- How will we do it?
- When are we going to do it?
- How will we know when we’re done?
As part of the planning phase, you will need to work with the team to put the full infrastructure in place and delegate specific tasks. This plan should include:
- Project management plan
- Project scope
- Work breakdown structure
- Resource plan
- Budget estimation
Bringing the plan together with input from the whole team is no small undertaking. When every department has the opportunity to contribute, however, potential issues are identified at an early stage, reducing the risk of delays further into the project.
Executing phase
The executing phase should encompass the following key elements:
- Team development
- Stakeholder engagement
- Quality assurance
- Communications
- Client management
This is the phase where the real work comes to fruition – where the majority of the budget is allocated and most of the project deliverables are produced. Your project plan moves from concept into action, whether that takes weeks, months, or even years. Throughout this period, communication is essential, as there will be times when the client or stakeholders require updates and progress reports.
A reliable project management system reduces the burden on your team considerably. Tasks become easier to track, deadlines and deliveries remain clearly visible, and the team has a clear view of what still needs to be done.
With Workfront, you can keep the entire project team informed and simplify reporting to clients and stakeholders.
Monitoring and controlling phase
During the monitoring and controlling phase, it is essential to maintain visibility across both overall project progress and its individual components. Staying vigilant and keeping pace with tracking and reporting ensures you remain aware of any potential problems before they have the chance to escalate.
It is also worth appointing another member of the project team (or one from each department) to act as a quality controller or reporter. They can help maintain oversight of everything within their team, holding regular meetings to provide updates on all aspects and ensuring the project stays on track.
Closing phase
The final phase of the project life cycle is the closing phase. It is far more than simply marking the project as complete and winding it down. It’s essential to formally close the project and secure sign-off or approval from the customer, stakeholders, and/or project sponsor.
This process might include:
- Delivering the project
- Hosting a post-mortem meeting
- Archiving project records
- Celebrating or acknowledging the achievement
- Officially disbanding or releasing the team
The importance of this final step in the project’s life cycle cannot be overstated. A growing number of organisations bring in temporary teams to complete a specific project, then disband and regroup for the next. This is particularly significant for project management teams – especially those involving freelancers or consultants.
The following table provides a high-level overview of these five process groups:
Adapting project phases to different project life cycle models
The five project management process groups demonstrate their versatility through their adaptability to a wide range of project life cycle models. The core principles – initiating, planning, executing, monitoring and controlling, and closing – remain constant throughout. However, their emphasis and mode of application can differ significantly – depending on whether the project follows a predictive, iterative, incremental, agile, or hybrid life cycle.
- Waterfall life cycle:In traditional predictive models – commonly known as the waterfall model – scope, time, and cost are established at the outset. Project life cycle phases are applied sequentially, with distinct phase gates marking each transition (e.g., completing all planning before execution begins). Although progressive elaboration still occurs during planning, the overall flow remains largely linear.
- Agile life cycles:Agile approaches, such as Scrum and Kanban, welcome change and involve rapid, iterative development cycles. Within each iteration or sprint, the process groups are applied in a highly condensed and repetitive fashion.
- Iterative and incremental life cycles:These models develop the product through repeated cycles (iterative) and/or deliver outputs in a series of functional increments (incremental). For example, an iteration might involve planning the features for that cycle, executing their development, monitoring progress, and then closing the iteration with a review – before planning the next.
- Hybrid life cycles:Hybrid models blend elements from both predictive and agile approaches to address specific project requirements. As a result, the application of process groups is tailored accordingly. A project might use detailed upfront planning for overall scope and architecture, followed by agile execution for specific components or features.
This adaptability demonstrates the strength of the PMI process group framework – one that is not rigidly tied to a single methodology. It provides a universal set of management functions that can be tailored to the unique context and requirements of any project, regardless of the chosen delivery approach. Project managers therefore have a consistent yet flexible toolkit to guide their projects to success.
