ISO 21502:2020 Clause 7.4.2 Defining the scope

Project Management 13 Minutes

Defining the scope should clarify what the project is planned to contribute to the objectives of the sponsoring organization or customer. The defined scope should be used as a factor to consider in future decisions, as well as when communicating the importance of the project and its objectives and benefits. The scope should reflect the requirements and their associated acceptance criteria and should be refined and clarified as work progresses.
The authorized work that forms the project’s scope can be defined in terms of the project’s objectives, mapping or in a work breakdown structure. As appropriate, the scope should be further elaborated and broken down into pieces of work in a work breakdown, or other type of structure. The breakdown identifies, defines and documents the work needed to provide a basis for planning. Associated acceptance criteria should be agreed.

In project management, defining the scope is a crucial step that involves clearly outlining the boundaries, deliverables, objectives, and requirements of the project. The organization typically defines the scope through a series of steps and documents, including:

  1. Project Charter: This is often the first document created in the project management process. It provides a high-level overview of the project, including its purpose, objectives, stakeholders, constraints, and initial scope. The project charter is usually developed by the project sponsor or initiator in collaboration with the project manager.
  2. Scope Statement: The scope statement is a detailed document that outlines the specific deliverables, features, functions, and tasks that need to be completed to achieve the project objectives. It defines what is included in the project and, equally importantly, what is not included (exclusions). The scope statement is typically developed based on the project charter and further elaborated upon during the planning phase.
  3. Work Breakdown Structure (WBS): The WBS is a hierarchical decomposition of the project scope into smaller, more manageable components called work packages. It breaks down the project work into smaller, more manageable tasks, making it easier to plan, execute, and monitor. The WBS serves as a foundation for creating the project schedule, budget, and resource allocation.
  4. Scope Management Plan: This document outlines how the project scope will be defined, validated, controlled, and managed throughout the project lifecycle. It includes processes for handling scope changes, managing stakeholders’ expectations, and ensuring alignment between the project scope and objectives.
  5. Requirements Documentation: Requirements documentation details the specific needs, features, and functionalities that the project deliverables must fulfill to satisfy stakeholders’ expectations. It includes both functional requirements (what the product or service should do) and non-functional requirements (qualities such as performance, usability, and security).
  6. Scope Verification and Control Processes: Scope verification involves formal acceptance of the completed project deliverables by the stakeholders, ensuring that they meet the specified requirements. Scope control involves monitoring the project scope and managing changes to prevent scope creep (uncontrolled expansion of project scope) and ensure that the project stays within its defined boundaries.

By following these steps and documents, the organization can effectively define and manage the scope of the project, thereby increasing the likelihood of project success and delivering value to stakeholders.

Defining the scope should clarify what the project is planned to contribute to the objectives of the sponsoring organization or customer.

Defining the scope of a project should indeed align closely with the objectives of the sponsoring organization or the customer. This alignment ensures that the project delivers value and contributes meaningfully to the overarching goals and strategic priorities. Here’s how the scope definition can clarify what the project aims to contribute to these objectives:

  1. Objective Alignment: The scope definition should explicitly state how the project aligns with the broader objectives of the organization or customer. It should highlight the specific goals or outcomes that the project is intended to achieve and how these contribute to the strategic vision.
  2. Deliverables and Outcomes: The scope definition should clearly outline the deliverables and outcomes that the project will produce. These deliverables should directly support the objectives by addressing specific needs or requirements identified by the organization or customer.
  3. Value Proposition: The scope definition should articulate the value proposition of the project—how it will deliver benefits or create value for the organization or customer. This could include improvements in efficiency, cost savings, revenue generation, customer satisfaction, or other strategic advantages.
  4. Key Performance Indicators (KPIs): The scope definition may also specify key performance indicators or success criteria that will be used to measure the project’s impact on organizational objectives. These KPIs provide a clear framework for evaluating the project’s effectiveness in contributing to desired outcomes.
  5. Alignment with Stakeholder Needs: The scope definition should take into account the needs and expectations of key stakeholders, including the sponsoring organization or customer. By understanding these needs, the project scope can be tailored to prioritize activities and deliverables that directly address them.
  6. Flexibility for Changes: While the initial scope definition should align closely with organizational objectives, it’s also important to allow for flexibility to accommodate changes in priorities or requirements over the course of the project. This may involve incorporating mechanisms for scope adjustments while still ensuring alignment with overarching goals.

By ensuring that the scope of the project is closely aligned with organizational objectives or customer needs, project managers can increase the likelihood of success and demonstrate the value of the project to stakeholders.

The defined scope should be used as a factor to consider in future decisions, as well as when communicating the importance of the project and its objectives and benefits.

The defined scope serves as a critical reference point throughout the project lifecycle and beyond. Here’s how it influences future decisions and communication regarding the project’s importance, objectives, and benefits:

  1. Decision Making: The defined scope acts as a guide for decision-making throughout the project. When faced with changes, challenges, or opportunities, project stakeholders can refer to the scope to assess whether proposed actions align with the project’s original objectives and boundaries. This ensures that decisions are made in the context of the project’s purpose and priorities.
  2. Resource Allocation: The scope helps in prioritizing resource allocation by providing clarity on the project’s goals and deliverables. It enables project managers to allocate resources (such as budget, personnel, and time) efficiently, focusing on activities that directly contribute to achieving the defined objectives and benefits.
  3. Risk Management: Understanding the project scope is essential for identifying and managing risks effectively. By knowing the boundaries and objectives of the project, project teams can anticipate potential risks and develop mitigation strategies to protect against scope creep, schedule delays, or budget overruns that could threaten the project’s success.
  4. Communication: The defined scope serves as a foundation for communicating the importance of the project, its objectives, and its anticipated benefits to stakeholders. When stakeholders understand the scope and how it aligns with organizational goals, they are more likely to support the project and remain engaged throughout its lifecycle. Clear communication about the scope also helps manage stakeholders’ expectations and reduce misunderstandings or conflicts.
  5. Performance Measurement: The scope provides criteria for measuring the project’s performance and success. By comparing actual progress and outcomes against the defined scope, project stakeholders can assess whether the project is on track to achieve its objectives and deliver the anticipated benefits. This information informs decision-making and adjustments to project plans as needed.
  6. Lessons Learned: After project completion, the defined scope serves as a basis for evaluating the project’s overall success and identifying lessons learned for future initiatives. By reflecting on how well the project scope was defined, managed, and adhered to, organizations can improve their project management practices and enhance future project outcomes.

In summary, the defined scope of a project is not only a starting point for planning and execution but also a crucial reference for ongoing decision-making, communication, risk management, performance measurement, and organizational learning.

The scope should reflect the requirements and their associated acceptance criteria and should be refined and clarified as work progresses.

Refining and clarifying the scope as work progresses is essential for ensuring that the project stays on track and delivers the intended outcomes. Here’s how the scope should reflect requirements and their associated acceptance criteria, and why refinement is crucial:

  1. Reflect Requirements and Acceptance Criteria: The scope definition should be closely aligned with the project requirements and their associated acceptance criteria. Requirements outline what needs to be achieved or delivered by the project, while acceptance criteria specify the conditions that must be met for the deliverables to be accepted by stakeholders. By incorporating requirements and acceptance criteria into the scope, the project team ensures that their efforts are directed towards fulfilling specific needs and expectations.
  2. Clarity and Alignment: As work progresses, it’s common for new insights, challenges, or changes to emerge. Refining and clarifying the scope allows the project team to address these developments and ensure that the project remains focused on its objectives. This may involve updating the scope statement, revising the work breakdown structure, or modifying project plans to reflect evolving requirements and priorities.
  3. Manage Scope Changes: Refining the scope also helps in managing scope changes effectively. As requirements evolve or new information becomes available, stakeholders may request changes to the project scope. By clearly defining the scope and associated requirements, the project team can evaluate proposed changes against established criteria and determine their impact on project objectives, schedule, and resources. This ensures that scope changes are carefully considered and aligned with project goals.
  4. Avoid Scope Creep: Scope creep, the gradual expansion of project scope beyond its original boundaries, can derail project timelines and budgets. By continuously refining and clarifying the scope, the project team can identify and address scope creep early on, ensuring that the project stays within its defined scope and resources are used efficiently.
  5. Ensure Stakeholder Satisfaction: Refining the scope based on evolving requirements and feedback helps ensure that project deliverables meet stakeholders’ expectations. By actively engaging stakeholders throughout the project lifecycle and incorporating their input into scope refinements, the project team can enhance stakeholder satisfaction and foster a collaborative project environment.
  6. Continuous Improvement: Iteratively refining the scope promotes continuous improvement in project management processes and practices. By reflecting on lessons learned from past projects and adapting the scope definition accordingly, organizations can enhance their ability to deliver successful outcomes in future initiatives.

In conclusion, refining and clarifying the project scope as work progresses is essential for maintaining alignment with requirements, managing scope changes, avoiding scope creep, ensuring stakeholder satisfaction, and promoting continuous improvement. This iterative approach helps increase the likelihood of project success and delivers value to stakeholders.

The authorized work that forms the project’s scope can be defined in terms of the project’s objectives, mapping or in a work breakdown structure.

The authorized work forming a project’s scope can be defined using various methods, including:

  1. Project Objectives: Defining the scope in terms of the project’s objectives involves aligning the work directly with what the project aims to achieve. This approach ensures that the scope is tightly focused on delivering the desired outcomes. By clearly articulating the project objectives, the scope can be structured to encompass all necessary tasks and deliverables required to meet those objectives.
  2. Project Mapping: Project mapping involves visualizing the scope of work in relation to the project’s goals and requirements. This may include creating diagrams, charts, or matrices that illustrate how different components of the project fit together to accomplish the overall objectives. Project mapping helps stakeholders understand the interrelationships between various tasks and deliverables, facilitating better planning and execution.
  3. Work Breakdown Structure (WBS): A Work Breakdown Structure (WBS) is a hierarchical decomposition of the project scope into smaller, more manageable components called work packages. Each work package represents a specific deliverable or task that contributes to achieving the project objectives. The WBS organizes the project scope in a structured manner, making it easier to plan, schedule, and allocate resources. It provides a clear roadmap for project execution and helps ensure that all necessary work is accounted for.

Each of these methods offers distinct advantages in defining the project scope:

  • Objectives-based approach ensures alignment with project goals, keeping the focus on delivering value.
  • Project mapping provides a visual representation of the scope, aiding in understanding and communication.
  • Work Breakdown Structure breaks down the scope into manageable components, facilitating planning and execution.

Project managers often use a combination of these methods to define the project scope comprehensively and accurately. By leveraging these approaches, project teams can ensure that the scope is well-defined, understood, and aligned with the project’s objectives, ultimately contributing to project success.

As appropriate, the scope should be further elaborated and broken down into pieces of work in a work breakdown, or other type of structure.

Further elaborating and breaking down the scope into manageable pieces of work is essential for effective project planning and execution. The Work Breakdown Structure (WBS) is a widely used method for structuring and organizing the project scope into smaller, more manageable components. However, other types of structures or techniques can also be employed depending on the nature of the project and specific requirements. Here’s how this process works:

  1. Work Breakdown Structure (WBS): The WBS is a hierarchical decomposition of the project scope into smaller work packages, each representing a specific deliverable or task. The WBS organizes the project scope in a structured manner, with higher-level elements representing major project phases or deliverables and lower-level elements breaking down these phases into more detailed tasks. This hierarchical structure helps in identifying all the work required to complete the project and provides a framework for planning, scheduling, and resource allocation.
  2. Organizational Breakdown Structure (OBS): The OBS is a hierarchical representation of the project organization, typically depicting the project team’s structure, roles, and responsibilities. While the WBS focuses on the breakdown of work, the OBS focuses on the breakdown of organizational units or resources involved in executing the project. Integrating the OBS with the WBS can help in ensuring that the right resources are assigned to the appropriate tasks and that responsibilities are clearly defined.
  3. Product Breakdown Structure (PBS): The PBS is a hierarchical decomposition of the project scope based on the products, services, or deliverables that the project will produce. Unlike the WBS, which focuses on the breakdown of work, the PBS focuses on the breakdown of project deliverables or outputs. This structure helps in understanding the project’s end products and can be used in conjunction with the WBS to ensure that all deliverables are accounted for and appropriately scoped.
  4. Risk Breakdown Structure (RBS): The RBS is a hierarchical representation of project risks, organized by risk categories or sources. Breaking down project risks into smaller, more manageable components helps in identifying, assessing, and managing risks effectively. Integrating the RBS with the WBS can help in identifying potential risks associated with specific work packages or project activities, allowing for proactive risk management.
  5. Capability Breakdown Structure (CBS): The CBS is a hierarchical representation of the project scope based on the capabilities or competencies required to deliver the project. This structure helps in identifying the skills, expertise, and resources needed to execute the project successfully. Integrating the CBS with the WBS can help in ensuring that the project team possesses the necessary capabilities to complete the work effectively.

By elaborating and breaking down the scope into pieces of work using appropriate structures or techniques, project teams can ensure that the scope is well-defined, understood, and manageable. This process facilitates more accurate planning, better resource allocation, and more effective execution, ultimately increasing the likelihood of project success.

The breakdown identifies, defines and documents the work needed to provide a basis for planning.

Breaking down the project scope into smaller, manageable components serves as the foundation for effective planning. Here’s how the breakdown process identifies, defines, and documents the work needed:

  1. Identification: The breakdown process begins with identifying all the tasks, activities, and deliverables required to complete the project. This involves analyzing the project scope statement, requirements documentation, and other relevant inputs to ensure comprehensive coverage of all necessary work. The goal is to capture every aspect of the project that contributes to achieving its objectives.
  2. Definition: Once the work components have been identified, they are further defined and clarified to ensure a common understanding among project stakeholders. This includes specifying the scope, objectives, requirements, and acceptance criteria for each work package or task. Clear definitions help in avoiding misunderstandings and ensure that everyone involved in the project knows what needs to be done.
  3. Documentation: The breakdown process involves documenting the identified work components, their descriptions, and associated details. This documentation typically takes the form of a Work Breakdown Structure (WBS), which organizes the work into a hierarchical structure. Each level of the WBS represents increasingly detailed levels of decomposition, providing a clear roadmap for project planning and execution. Additionally, other documents such as task lists, schedules, and resource assignments may be created to support planning efforts.
  4. Basis for Planning: The breakdown of work serves as the basis for developing project plans, including schedules, budgets, resource allocations, and risk management strategies. By having a clear understanding of the project’s scope and work breakdown, project managers can create realistic and achievable plans that account for all necessary tasks and activities. The breakdown provides the granularity needed to estimate time, cost, and resource requirements accurately, facilitating effective project management.
  5. Continuous Refinement: Throughout the project lifecycle, the breakdown of work may be refined and updated as new information becomes available or project requirements change. This iterative process ensures that the project remains aligned with its objectives and adapts to evolving circumstances. By continuously refining the breakdown, project teams can optimize planning efforts and improve project outcomes.

Overall, the breakdown of work into smaller components serves as a critical step in project planning, providing the detailed foundation needed to effectively manage and execute the project. By identifying, defining, and documenting the work, project teams can ensure that all necessary tasks are accounted for and that plans are based on a comprehensive understanding of the project scope.

Associated acceptance criteria should be agreed.

Agreeing on associated acceptance criteria is crucial for ensuring that project deliverables meet stakeholders’ expectations and requirements. Acceptance criteria define the conditions that must be met for a deliverable to be considered complete and acceptable. Here’s why agreeing on acceptance criteria is important:

  1. Clear Expectations: Acceptance criteria provide clear, objective standards for evaluating the quality and completeness of project deliverables. By defining specific criteria that must be met, stakeholders can set clear expectations for what constitutes a successful outcome.
  2. Alignment with Requirements: Acceptance criteria ensure alignment between project deliverables and stakeholder requirements. By explicitly stating the conditions that must be satisfied, acceptance criteria help ensure that deliverables meet the intended purpose and functionality.
  3. Verification of Success: Acceptance criteria serve as a basis for verifying the success of project deliverables. Once the deliverable is completed, stakeholders can use the acceptance criteria to validate whether it meets their needs and expectations.
  4. Reduced Ambiguity: Clearly defined acceptance criteria reduce ambiguity and misunderstanding regarding project requirements. By establishing specific, measurable criteria for success, stakeholders can avoid subjective interpretations and ensure a shared understanding of project deliverables.
  5. Facilitates Communication: Agreeing on acceptance criteria facilitates communication between project stakeholders, including the project team, customers, sponsors, and end-users. By collaboratively defining acceptance criteria, stakeholders can ensure that everyone has a common understanding of project expectations and goals.
  6. Mitigates Risks: Establishing acceptance criteria early in the project lifecycle helps mitigate risks associated with unclear or changing requirements. By documenting and agreeing on acceptance criteria upfront, project teams can reduce the likelihood of scope creep, misunderstandings, and project delays.
  7. Improves Accountability: Acceptance criteria provide a basis for holding project teams accountable for delivering high-quality results. By clearly defining the standards for success, stakeholders can evaluate whether project deliverables meet the agreed-upon criteria and hold the project team accountable for any deficiencies.

Overall, agreeing on acceptance criteria is essential for ensuring project success by establishing clear expectations, aligning deliverables with requirements, facilitating communication, reducing ambiguity, mitigating risks, and improving accountability. By collaboratively defining acceptance criteria, project stakeholders can increase the likelihood of achieving project objectives and delivering value to stakeholders.
