ISO 21502:2020 Clause 4.4 Project life cycle

The following should be considered when defining a project’s life cycle:

1. organizational and project governance;
2. risks;
3. control factors;
4. the nature or characteristics of the project;
5. other organizational and environmental factors.

The number and names of a project’s phases depend upon the type of project being undertaken, desired governance, and the anticipated risk. The phases can reflect the delivery approach being taken, such as predictive, iterative, incremental, adaptive or a hybrid of approaches. Management methods often use different words to denote phases, such as “stage”, “iteration” and “release”.
The phases should have a defined start and end. Each phase of the project life cycle should have specific milestones that relate to the decisions, key deliverables, outputs or outcomes. Each phase should be preceded by a decision point. These decision points, often referred to as “gates”, are essential aspects of project governance. The criteria to be met to authorize the start of a phase should be defined but can vary depending on the organizational environment, the specific life cycle being used and the established project governance. In some cases, phases can overlap.
The decision points and phases, should be defined and can vary depending on the organizational and external environments, funding, benefits required, risk and constraints.
Figure below illustrates the linkages between the project life cycle, integrated project management practices and the management practices for a project.

A project life cycle is a series of phases that a project goes through from initiation to completion. It provides a structured framework for planning, executing, and closing a project. The life cycle defines the key stages, milestones, and deliverables involved in managing a project. While the specific phases and terminology may vary across different project management methodologies, a common project life cycle typically includes the following stages:

1. Initiation: This is the starting point of the project. During this phase, the project is defined at a broad level. The goals, scope, purpose, and feasibility of the project are identified. Key stakeholders are identified, and initial resources are allocated.
2. Planning: In this phase, detailed planning takes place. Project managers and teams develop a comprehensive project plan that includes scope definition, project schedule, budget, risk management plan, communication plan, and other essential components. The planning phase lays the foundation for project execution.
3. Execution: This is the phase where the project plan is put into motion. Resources are allocated, teams are informed, and tasks are executed. The project manager’s role is crucial during this phase as they coordinate and direct project activities to achieve the defined objectives. Monitoring and controlling activities are also crucial to ensure that the project stays on track.
4. Monitoring and Controlling: Throughout the project, progress and performance are monitored against the project management plan. Changes to the plan may be made based on the monitoring results. This phase involves tracking, reviewing, and regulating the progress and performance of the project.
5. Closing: The closing phase occurs when the project is completed or terminated. This involves finalizing all project activities, completing any remaining deliverables, obtaining customer or stakeholder acceptance, releasing project resources, and formally closing out the project. A post-project review or lessons learned session may also be conducted to capture insights and improvements for future projects.

Determining the appropriate project life cycle for an organization involves considering various factors, including the nature of the project, organizational goals, industry standards, and stakeholder requirements. Here are steps to help organizations determine the project life cycle:

1. Understand Project Characteristics: Examine the nature of the project. Is it a highly innovative project with evolving requirements, or is it a well-defined project with stable requirements? Consider the size and complexity of the project. Larger and more complex projects may benefit from a different life cycle approach than smaller, straightforward projects.
2. Assess Stakeholder Expectations: Understand the expectations of key stakeholders. Some stakeholders may prefer a more iterative and flexible approach, while others may prefer a structured and linear process.
3. Consider Industry Standards: Evaluate industry standards and best practices. Certain industries or types of projects may have established norms for project life cycles. For example, software development often uses iterative approaches like Agile, while construction projects may follow a more traditional, sequential approach.
4. Review Organizational Culture: Assess the organizational culture and the level of flexibility it allows. Some organizations are more adaptable to change and may benefit from Agile or iterative approaches, while others may prefer a more traditional, waterfall approach.
5. Evaluate Project Complexity and Uncertainty: Consider the level of uncertainty and complexity associated with the project. Projects with high uncertainty or rapidly changing requirements may benefit from iterative and incremental life cycles, whereas projects with well-defined requirements may align better with a linear approach.
6. Define Project Goals and Objectives: Clearly define the goals and objectives of the project. Understanding what the organization aims to achieve with the project can influence the choice of a life cycle. For example, if speed to market is crucial, an Agile or iterative approach might be more appropriate.
7. Consider Risk Tolerance: Assess the organization’s tolerance for risk. Some life cycles are better suited for managing and mitigating risks, while others may introduce more predictability and control.
8. Consult Project Management Experts: Seek input from project management experts within the organization or external consultants. They can provide insights based on their experience and knowledge of various project management methodologies.
9. Pilot Projects: Consider piloting different life cycles on small or less critical projects. This allows the organization to test and evaluate the effectiveness of different approaches before implementing them on larger, more critical initiatives.
10. Flexibility and Adaptability: Choose a life cycle that allows for flexibility and adaptability. The chosen life cycle should be able to accommodate changes in project requirements and respond effectively to unforeseen challenges.

By carefully considering these factors, organizations can make informed decisions about which project life cycle is most appropriate for a given project. It’s important to note that there is no one-size-fits-all approach, and the chosen life cycle may vary from project to project within the same organization.

When defining the project life cycle the organization must consider the organizational and project governance.

Considering organizational and project governance is crucial when defining the project life cycle. Governance provides the framework for decision-making, accountability, and ensuring that projects align with the overall strategic objectives of the organization.By integrating governance considerations into the definition of the project life cycle, organizations can enhance project success, manage risks effectively, and ensure that projects contribute to the overall success of the organization. Clear governance structures provide a framework for accountability, transparency, and decision-making throughout the project life cycle. Here’s how organizational and project governance considerations come into play:

1. Alignment with Organizational Strategy: The project life cycle should align with the overall strategic goals and objectives of the organization. Governance structures ensure that projects contribute to the organization’s mission and vision.
2. Decision-Making Authority: Clearly define decision-making authority at various stages of the project life cycle. Governance structures help identify who has the authority to make key decisions, allocate resources, and approve changes.
3. Risk Management: Governance mechanisms assist in defining how risks will be identified, assessed, and managed throughout the project life cycle. This includes determining risk tolerance levels and establishing processes for escalation when necessary.
4. Compliance and Standards: Ensure that the project life cycle adheres to any regulatory requirements, industry standards, or compliance frameworks relevant to the organization. Governance helps establish and enforce these standards.
5. Resource Allocation: Organizational governance structures play a role in determining how resources, both human and financial, are allocated to projects. This includes budgeting, staffing, and prioritizing projects based on organizational priorities.
6. Stakeholder Engagement: Governance outlines how stakeholders are identified, engaged, and communicated with throughout the project life cycle. This ensures that the interests of various stakeholders are considered and addressed appropriately.
7. Reporting and Transparency: Define reporting mechanisms and establish transparency throughout the project life cycle. Governance structures often include regular reporting requirements to keep stakeholders informed of project progress, issues, and changes.
8. Change Control: Clearly define processes for managing changes to the project scope, schedule, and budget. Governance structures help establish change control processes, including how changes are evaluated, approved, and communicated.
9. Quality Assurance: Determine how quality will be assured throughout the project life cycle. Governance mechanisms should include processes for defining and measuring project deliverable quality, as well as mechanisms for addressing deviations.
10. Project Closure and Evaluation: Governance structures guide the formal closure of a project, including the evaluation of project success and lessons learned. This information is valuable for continuous improvement and informs future projects.
11. Adherence to Methodologies: If the organization follows specific project management methodologies (e.g., Agile, Waterfall), governance ensures that projects adhere to these methodologies and that teams are appropriately trained.

When defining the project life cycle the organization must consider the risks.

Considering risks is a critical aspect of defining the project life cycle. A thorough understanding of potential risks and uncertainties helps organizations develop strategies for risk mitigation, contingency planning, and overall project management.By actively considering risks throughout the project life cycle, organizations can enhance their ability to navigate uncertainties and increase the likelihood of project success. The integration of risk management practices ensures that the project team is well-prepared to address challenges and capitalize on opportunities as they arise. Here are ways in which organizations can integrate risk considerations into the definition of the project life cycle:

1. Risk Identification: Begin by systematically identifying potential risks associated with the project. Consider both internal and external factors that could impact project objectives, timelines, and deliverables. Involve key stakeholders in this process to gather diverse perspectives.
2. Risk Assessment: Assess the likelihood and impact of identified risks. This involves analyzing the probability of each risk occurring and the potential consequences on the project. Prioritize risks based on their significance to project success.
3. Risk Planning: Develop a risk management plan that outlines strategies for mitigating, avoiding, or transferring identified risks. Consider creating contingency plans for high-priority risks to ensure that the project can respond effectively if certain events unfold.
4. Integration with Project Life Cycle Phases: Integrate risk management activities into each phase of the project life cycle. For example, during the planning phase, focus on risk identification and planning. During the execution phase, monitor and control identified risks, and during closure, conduct a final assessment of how risks were managed.
5. Risk Tolerance and Appetite: Define the organization’s risk tolerance and appetite. Different projects may have varying levels of acceptable risk. Some projects, especially those in dynamic environments, may tolerate higher levels of uncertainty, while others may prioritize stability and predictability.
6. Contingency Planning: Develop contingency plans for high-impact risks. Contingency planning involves identifying specific actions to be taken if certain risks materialize. This ensures that the project team is prepared to respond promptly and effectively to unforeseen events.
7. Communication of Risks: Establish clear communication channels for discussing and reporting risks. Ensure that project stakeholders are informed about potential risks, mitigation strategies, and any changes to the risk profile throughout the project life cycle.
8. Monitoring and Control: Implement mechanisms for ongoing monitoring and control of risks. Regularly review the risk landscape and update risk responses as needed. This proactive approach helps in identifying emerging risks and adjusting the project plan accordingly.
9. Lessons Learned: Incorporate a lessons learned process at the end of the project to capture insights related to risk management. Document what worked well, what could be improved, and how similar risks can be better addressed in future projects.
10. Adaptability to Change: Design the project life cycle to be adaptable to changes in the risk landscape. Flexible methodologies, such as Agile, can be particularly useful in environments where risks are dynamic and may evolve throughout the project.

When defining the project life cycle the organization must consider the control factors.

Considering control factors is essential when defining the project life cycle. Control factors help organizations establish mechanisms to monitor, regulate, and manage various aspects of the project to ensure it stays on course and meets its objectives.By integrating these control factors into the project life cycle, organizations can establish a robust framework for managing and regulating project activities. This ensures that the project is executed efficiently, risks are addressed promptly, and stakeholders are informed throughout the process. Effective control mechanisms contribute to the overall success and quality of the project outcomes. Here are key control factors that organizations should consider during the definition of the project life cycle:

1. Scope Control: Clearly define and control the project scope. Establish processes for scope identification, validation, and change management. This helps prevent scope creep and ensures that the project stays focused on its original objectives.
2. Schedule Control: Implement mechanisms for tracking and controlling the project schedule. This includes creating a project schedule, monitoring progress, identifying schedule variances, and implementing corrective actions as needed to keep the project on track.
3. Cost Control: Define processes for budgeting, tracking, and controlling project costs. Establish cost baselines, monitor actual expenditures against the budget, and implement cost control measures to manage financial resources effectively.
4. Quality Control: Incorporate quality control processes to ensure that project deliverables meet predefined quality standards. Define quality metrics, conduct inspections, and implement corrective actions to address deviations from quality requirements.
5. Risk Control: Develop strategies for monitoring and controlling project risks. Implement risk response plans and regularly review the risk landscape to identify and address new or changing risks throughout the project life cycle.
6. Communication Control: Establish communication plans to ensure effective and timely information flow within the project team and with stakeholders. Control factors should include regular status updates, issue reporting, and mechanisms for addressing communication challenges.

The phases can reflect the delivery approach being taken, such as predictive, iterative, incremental, adaptive or a hybrid of approaches.

The delivery approach is a key factor influencing the structure of project phases. Different project delivery approaches, such as predictive (Waterfall), iterative, incremental, adaptive (Agile), or hybrid models, have distinct characteristics that shape how the project is organized and executed.The choice of the delivery approach and the corresponding phases depends on factors such as project requirements, organizational culture, stakeholder expectations, and the nature of the work. Some projects may benefit from a more structured and sequential approach, while others require the adaptability and collaboration provided by iterative or Agile methodologies. The key is to select an approach that aligns with the project’s goals and context. Here’s how these delivery approaches can impact the phases of a project:

1. Predictive (Waterfall) Approach: In a predictive or Waterfall approach, the project life cycle is typically divided into sequential and linear phases. Each phase must be completed before moving to the next. Common phases include:
   • Initiation: Defining the project and obtaining approval.
   • Planning: Detailed planning of scope, schedule, and resources.
   • Execution: Implementation of the project plan.
   • Monitoring and Controlling: Tracking and managing project progress.
   • Closing: Finalizing and closing out the project.
2. Iterative Approach: In an iterative approach, the project life cycle involves repeating cycles or iterations of planning, executing, and evaluating. Each iteration enhances the project based on feedback. Phases may include:
   • Concept Development: Initial planning and idea generation.
   • Iteration: Repeated cycles of development and refinement.
   • Testing and Evaluation: Assessment of the product or deliverables.
   • Deployment: Final deployment of the solution.
3. Incremental Approach: An incremental approach involves delivering the project in increments or portions. Each increment adds new features or capabilities. Phases may include:
   • Planning: Initial planning of the entire project.
   • Incremental Development: Building the project in stages.
   • Testing and Evaluation: Assessing each increment.
   • Deployment: Deploying each increment.
4. Adaptive (Agile) Approach: Agile methodologies, such as Scrum or Kanban, emphasize flexibility, collaboration, and responsiveness to change. Phases are more fluid, often represented as iterative cycles or sprints:
   • Backlog Refinement: Planning and prioritizing work items.
   • Sprint Planning: Planning for a specific time-boxed iteration.
   • Development and Testing: Execution of planned work.
   • Review and Retrospective: Evaluation and improvement.
5. Hybrid Approach: Organizations often adopt a hybrid approach that combines elements of different delivery models to suit their specific needs. For example:
   • Combining predictive planning with iterative development cycles.
   • Using Agile practices for specific phases within a larger Waterfall structure.
   • Customizing the project life cycle based on a blend of methodologies.

Management methods often use different words to denote phases, such as “stage”, “iteration” and “release”.

Different management methods and project management frameworks often use distinct terminology to denote phases, stages, iterations, or releases. The choice of words reflects the specific concepts and processes associated with each approach.The use of different terms reflects the diverse philosophies and principles underlying each project management methodology. It’s essential for project teams to be familiar with the terminology associated with their chosen approach to ensure effective communication and understanding across all stakeholders. Here’s a brief overview of how some common management methods use different terms for phases:

1. Waterfall (Predictive) Approach: Waterfall methodology typically uses the term “stage” to denote distinct phases in the project life cycle. These stages are sequential, with each stage building on the deliverables of the previous one.
2. Agile (Scrum) Approach: Agile methodologies, particularly Scrum, use terms like “iteration” and “sprint” to denote short, time-boxed development cycles. The project is divided into a series of iterations, with each iteration delivering a potentially shippable product increment. The term “release” is also used to refer to a version of the product that is ready for deployment.
3. Incremental Approach: In an incremental approach, the term “increment” is commonly used to represent portions of the project that are developed and delivered in stages. Each increment adds new features or capabilities to the project.
4. Iterative Approach: In an iterative approach, the term “iteration” is used to describe the repetition of cycles where work is planned, executed, and evaluated. Iterations allow for continuous improvement based on feedback.
5. Hybrid Approach: Organizations using a hybrid approach may adopt a mix of terminology based on their unique project management framework. For instance, they might have a “planning phase” (similar to Waterfall) followed by “Agile sprints” for development.
6. PRINCE2 (PRojects IN Controlled Environments) Approach: PRINCE2, a popular project management framework, uses the term “stage” to denote distinct phases in the project life cycle. Each stage has specific processes and deliverables, contributing to overall project control.
7. Kanban Approach: Kanban, another Agile methodology, uses the term “board” to visualize and manage work. Work items move through different stages on the board, representing the flow of work from inception to completion.
8. Extreme Programming (XP) Approach: Extreme Programming (XP) uses the term “release” to denote a version of the software that is deemed complete and ready for deployment. XP emphasizes frequent releases to gather feedback early and often.

The phases should have a defined start and end.

One of the fundamental characteristics of project phases is that they should have a defined start and end. This characteristic helps provide structure and clarity to the project life cycle.Having a defined start and end for phases is a fundamental aspect of effective project management. It brings structure to the project life cycle, supports efficient resource utilization, enhances risk management, and facilitates communication among project stakeholders.

9. Stakeholder Engagement: Phases provide opportunities for stakeholder engagement and feedback. At the end of each phase, stakeholders can review progress, provide input, and ensure that the project remains aligned with their expectations.
10. Project Closure: The end of the final phase marks the project’s closure. This includes the formal acceptance of deliverables, the release of project resources, and the documentation of lessons learned. Clear phase boundaries contribute to a smooth and organized project closure process.

Each phase of the project life cycle should have specific milestones that relate to the decisions, key deliverables, outputs or outcomes.

Defining specific milestones for each phase of the project life cycle is crucial for effective project management. Milestones represent significant points of progress and achievement within a project, and they are typically associated with key decisions, deliverables, outputs, or outcomes.By establishing specific milestones for each phase, project managers and teams create a structured framework for project management. Milestones enhance visibility, accountability, and control throughout the project life cycle, contributing to successful project delivery. Here’s why milestones are important and how they contribute to successful project management:

1. Decision Points: Milestones often coincide with decision points where key choices need to be made. For example, at the end of the planning phase, a milestone might involve the decision to proceed with the project based on the approved plan.
2. Progress Measurement: Milestones serve as markers for measuring project progress. They provide clear indicators of how far the project has advanced and allow stakeholders to assess whether the project is on track.
3. Quality Checkpoints: Milestones are often associated with the completion of key deliverables or phases, providing natural checkpoints for quality assurance. Teams can conduct reviews and ensure that deliverables meet predefined standards.
4. Resource Allocation: Clear milestones help in the effective allocation of resources. Teams can plan resource utilization based on the timing of milestones, ensuring that the right resources are available when needed.
5. Risk Management: Milestones contribute to risk management by providing opportunities to assess and mitigate risks at specific points in the project. This ensures that any potential issues are addressed before they escalate.
6. Stakeholder Communication: Milestones are important communication tools. They allow project managers to update stakeholders on project progress, highlight achievements, and discuss upcoming phases or decisions.
7. Client and Stakeholder Involvement: Milestones often involve the participation of clients or key stakeholders. These points provide opportunities for stakeholder engagement, feedback, and alignment with project goals.
8. Change Control: Milestones are associated with the end of phases, providing natural points for change control. Any proposed changes can be evaluated and approved or rejected before progressing to the next phase.
9. Project Control and Monitoring: Milestones support project control and monitoring activities. Project managers can use milestones to track progress against the project schedule, identify deviations, and take corrective actions if necessary.
10. Documentation and Lessons Learned: At milestones, project documentation can be updated, and lessons learned can be captured. This contributes to a comprehensive record of the project’s evolution and facilitates continuous improvement.
11. Project Closure: The final milestone marks the project closure. At this point, deliverables are formally accepted, and any remaining activities, such as documentation and handovers, are completed.
12. Motivation and Recognition: Achieving milestones provides a sense of accomplishment for the project team. Recognizing and celebrating milestones can boost team morale and motivation.

Each phase should be preceded by a decision point.

The concept of decision points preceding each phase is fundamental to effective project management. Decision points are critical moments where key stakeholders evaluate the project’s status and make informed decisions regarding whether to proceed to the next phase. These decision points add a layer of control and validation to the project life cycle. By incorporating decision points preceding each phase, project managers and teams introduce a structured approach to project governance. This approach enhances control, transparency, and the likelihood of project success by ensuring that informed decisions are made at critical junctures in the project life cycle. Here’s why decision points preceding each phase are important:

1. Validation of Readiness: Decision points ensure that the project team and key stakeholders validate the readiness of the project to move into the next phase. This involves assessing whether the necessary prerequisites, resources, and preparations are in place.
2. Alignment with Objectives: Decision points allow stakeholders to assess whether the project’s objectives and goals align with the organization’s strategic priorities. This ensures that the project remains aligned with the overall mission and vision.
3. Risk Assessment and Mitigation: Before entering a new phase, decision points provide an opportunity to assess and mitigate risks. The project team and stakeholders can review potential challenges and uncertainties, making informed decisions on how to address them proactively.
4. Quality Assurance: Decision points coincide with quality checkpoints. Stakeholders can review the quality of deliverables and outputs from the previous phase, ensuring that they meet established standards before progressing.
5. Resource Planning and Allocation: Decision points allow for the review and adjustment of resource plans. Stakeholders can assess whether the allocation of resources, including personnel, budget, and equipment, is sufficient and appropriate for the upcoming phase.
6. Budget and Schedule Review: Decision points provide an opportunity to review the project’s budget and schedule. Stakeholders can evaluate whether the project is progressing according to the planned timelines and financial constraints.
7. Stakeholder Involvement and Communication: Decision points facilitate stakeholder involvement and communication. Key stakeholders can participate in reviews, provide feedback, and make decisions about the project’s direction based on the information presented at the decision point.

These decision points, often referred to as “gates”, are essential aspects of project governance.

The decision points, often referred to as “gates,” are essential components of project governance. Project governance involves the framework, processes, and decision-making structures that guide and control the project throughout its life cycle. Gates serve as checkpoints or milestones within this governance framework, ensuring that the project progresses in a controlled and well-informed manner. Here’s why gates are crucial for effective project governance:

1. Risk Management: Gates provide opportunities to assess and mitigate risks. Before proceeding to the next phase, stakeholders can review the project’s risk profile, make decisions on risk responses, and ensure that the project is adequately prepared for potential challenges.
2. Quality Assurance: Gates coincide with quality assurance activities. Stakeholders evaluate the quality of deliverables and outputs from the previous phase, ensuring that they meet specified standards before allowing the project to move forward.
3. Decision-Making Authority: Gates define decision-making points and the authority responsible for making key decisions. This clarity ensures that decisions are made by the appropriate stakeholders, considering their expertise and perspectives.
4. Alignment with Strategic Objectives: At gates, stakeholders assess whether the project aligns with strategic objectives. This evaluation helps ensure that the project remains in line with the organization’s overall goals and contributes to its long-term vision.
5. Resource Management: Gates allow for a review of resource plans and allocation. Stakeholders can assess whether the project has the necessary resources for the upcoming phase, making adjustments as needed to support successful project execution.
6. Budget and Schedule Control: Gates serve as control points for reviewing the project’s budget and schedule. Stakeholders evaluate whether the project is progressing according to the planned timelines and financial constraints, making adjustments if required.
7. Client and Stakeholder Engagement: Gates provide opportunities for client and stakeholder engagement. Clients can participate in reviews, provide feedback, and make decisions regarding the project’s direction, ensuring that their expectations are considered.
8. Change Management: Gates are integral to change management processes. If there are proposed changes to the project, stakeholders can assess the impact of these changes and make decisions on whether to approve or reject them before the project proceeds.
9. Documentation and Reporting: At gates, project documentation is typically updated, and comprehensive reports are presented to stakeholders. This ensures that all relevant information is available for informed decision-making.
10. Learning and Continuous Improvement: Gates provide opportunities for learning from project experiences. Lessons learned from the previous phase can be documented and applied to improve processes, decision-making, and overall project performance.
11. Project Closure Approval: The final gate often involves the approval for project closure. Stakeholders review the project’s achievements, ensure that all deliverables are in order, and provide formal approval for closing the project.

The criteria to be met to authorize the start of a phase should be defined but can vary depending on the organizational environment, the specific life cycle being used and the established project governance. In some cases, phases can overlap.

The criteria for authorizing the start of a phase, often referred to as entry criteria, should be well-defined, but they can indeed vary based on the organizational environment, the specific life cycle being used, and the established project governance. Additionally, the flexibility to allow phases to overlap is often influenced by the nature of the project and the chosen project management methodology.It’s essential for project managers and teams to carefully consider these factors when defining entry criteria for each project phase. A well-thought-out and tailored approach ensures that the project progresses in a controlled and effective manner, aligning with organizational goals and project success criteria.
