Project scope is the part of project planning that involves determining and documenting a list of specific project goals, deliverables, tasks, costs and deadlines. The documentation of a project's scope, which is called a scope statement, terms of reference or statement of work, explains the boundaries of the project, establishes responsibilities for each team member and sets up procedures for how completed work will be verified and approved. During the project, this documentation helps the project team remain focused and on task. The scope statement also provides the project team with guidelines for making decisions about change requests during the project. Please note, a project's scope statement should not be confused with its charter; a project's charter simply documents that the project exists.

It is natural for parts of a large project to change along the way, so the better the project has been "scoped" at the beginning, the better the project team will be able to manage change. When documenting a project's scope, stakeholders should be as specific as possible in order to avoid scope creep, a situation in which one or more parts of a project ends up requiring more work, time or effort because of poor planning or miscommunication. Effective scope management requires good communication to ensure that everyone on the team understands the scope of the project and agrees upon exactly how the project's goals will be met. As part of project scope management, the team leader should solicit approvals and sign-offs from the various stakeholders as the project proceeds, ensuring that the finished project, as proposed, meets everyone's needs.
The importance of defining a project's scope
Here are the benefits a project scope statement provides to any organization undertaking a new initiative. It:
- articulates what the project entails so that all stakeholders can understand what's involved;
- provides a roadmap that managers can use to assign tasks, schedule work and budget appropriately;
- helps focus team members on common objectives; and
- prevents projects, particularly complex ones, from expanding beyond the established vision.
Project managers generally find that establishing project scope ensures projects are focused and executed to expectations. The scope provides a strong foundation for managing a project as it moves forward and helps ensure that resources aren't diverted or wasted on out-of-scope elements.
How to define the scope of a project
Defining project scope requires input from the project stakeholders, who together with project managers establish the key elements of budget, objectives, quality and timeline. To determine a project scope, project managers must collect requirements for what the stakeholders need from the project -- this includes the project's objective or the project's deliverables, when the project needs to be completed, and how much they can pay for it. The goal is to gather and record precise and accurate information during this process, so that the project scope effectively reflects all requirements and thus improves the chances for project leaders to deliver products that meet stakeholder expectations on time and on budget.
Writing a project scope statement
A project scope statement is a written document that includes all the required information for producing the project deliverables. More detailed than a statement of work, the project scope statement helps the project team remain focused and on task. The scope statement also provides the project team leader or facilitator with guidelines for making decisions about change requests during the project. It is natural for parts of a large project to change along the way, so the better the project has been scoped at the beginning, the better the project team will be able to manage change.
The project scope statement also establishes what is not included in initiatives, either implicitly or explicitly. Objectives and tasks not listed in the project scope statement should be considered out of scope. Project managers can also list specific work that will not be part of the project. As such, this statement establishes the boundaries of each specific project. Project leaders need to take those requirements and map out what should happen and in what order those items need to occur. This generally leads to the creation of a work breakdown structure (WBS). As the name states, the work breakdown structure breaks down the totality of planned work into smaller portions and required tasks.
A well-articulated scope statement is considered a critical part of effective project management and project scope should be determined for every project, regardless of what project management methodology is used. Stakeholders for the project should have the opportunity to review the project scope statement, revise it as necessary and then approve it. Once a project scope is completed and approved, project managers can effectively allocate tasks and give their teams directions on what they each need to do to meet the target timelines and costs.
Scope management and planning
Project managers should anticipate the need for updates and changes as projects progress, carefully control what changes are made to the established project scope and document all changes made during the process. This requires strong project management skills. It also requires project managers and stakeholders to adhere to the project scope statement by recognizing what pieces are within the project scope and what requests are out of scope.
Project managers should rely on change management processes that determine how such requests should be evaluated while considering updates and alterations to the project. The ability to distinguish between which requests are truly needed and which are out of scope allows organizations to avoid scope creep. Scope creep happens when more and more work is tacked onto projects as they're underway. Scope creep frequently adds extra costs and unnecessarily work while muddling objectives and threatening the quality of the intended deliverables.
Project scope vs. product scope
Project scope should not be confused with product scope. Product scope defines the capabilities, characteristics, features and functions of the end result of the project. Project leaders should create a product scope statement and they should use both the project scope and the product scope statements to support each other and establish for their organizations a clear understanding of what every project aims to achieve.
