Project Charter
What is Project Charter?
A project charter is a short document that formally authorizes a project, stating its purpose, objectives, scope, key stakeholders, high-level budget and timeline, and the authority given to the project manager.

A project charter is usually the first formal document a project produces. It records why the project exists, what it is expected to achieve, roughly what it will cost and how long it will take, who is sponsoring it and who will manage it. Once the sponsor signs it, the project is officially approved to start, and the project manager has the authority to use the people and money assigned to it. Before that point, any work is usually limited to the analysis needed to prepare the charter. Detailed plans come later; the charter sets the boundaries those plans must fit within.
The charter's main value is shared understanding. Many projects run into trouble because the sponsor, the project team and the people affected by the work had different ideas of what the project was for. Writing these down at the start, in plain language, exposes disagreements while they are still cheap to resolve. For portfolio leaders and PMOs, the charter is also the point at which a proposal becomes a funded project in the portfolio, with an owner, a budget and objectives that can later be measured.
Definition of a Project Charter
A project charter is a document issued by a project's sponsor that formally authorizes the project's existence and gives the project manager authority to apply organizational resources to its activities.
It usually follows a business case, which justifies the investment, and precedes the detailed project plan. It marks the start of the project lifecycle and is often required at the first approval gate in a stage-gate process.
What a Project Charter Contains
Purpose and business need explain why the project is being undertaken and which strategic goal it supports.
Objectives and success criteria state what the project must achieve, in measurable terms where possible.
Scope describes what is included and, just as importantly, what is excluded. Listing exclusions explicitly prevents stakeholders from assuming that related work is covered.
Stakeholders, roles and governance name the sponsor, the project manager, key stakeholders and how decisions will be made, such as through a steering committee.
Budget, timeline, key risks, assumptions and constraints give a high-level view of cost, major milestones and what could affect success.
Project Charter vs Business Case vs Project Plan
A business case asks whether the investment is worth making, comparing expected costs and benefits with alternatives.
A project charter confirms that the project is approved and sets its boundaries, objectives and authority.
A project plan describes in detail how the work will be done, including tasks, schedule, resources and controls.
In smaller organizations these are sometimes combined into one document, but keeping their purposes distinct helps make sure each question is answered. Whatever the format, the charter should be the document stakeholders can point to when they need to confirm what was agreed.
Importance of the Project Charter in Strategic Portfolio Management
The charter links each project to the portfolio. By stating which strategic goal the project supports and how success will be measured, it makes the project's contribution visible in portfolio reviews.
It reduces scope creep. With scope and exclusions written down and agreed, requests for additional work can be assessed against the original agreement rather than accepted by default.
It also clarifies accountability. Naming the sponsor and project manager, and the authority each holds, prevents confusion about who makes decisions.
The Project Charter and Financial Management
The charter records the approved budget and any funding conditions, giving finance and the PMO a baseline against which to track spending.
Linking the charter to the business case allows benefits to be tracked after delivery, supporting comparisons of expected and actual return on investment.
Some organizations approve only the first phase of funding in the charter, with further funding released at later gates as the project proves itself.
Recording whether costs are expected to be capital or operating expense helps finance teams plan for capitalization and depreciation from the start.
Common Challenges
Charters are sometimes treated as paperwork, filled in quickly and never read again, which wastes their value as a shared reference. A charter that no stakeholder has read cannot resolve the disagreements it was meant to prevent.
Objectives are often vague, such as improving efficiency, which makes success impossible to judge.
Charters may not be updated when major changes are agreed, leaving the project working to a scope or budget that no longer reflects reality.
How to Write a Project Charter
Writing a good project charter involves agreeing the essentials with the sponsor, keeping the document short and making sure it is formally approved.
Most effective charters fit on one to three pages, focusing on decisions and boundaries rather than detail.
Drafting the Charter
Start from the business case and confirm with the sponsor which strategic goal the project supports and why it matters now.
Write objectives that can be measured, such as reducing processing time by 30% or retiring a named system, and state how they will be assessed.
Define scope and exclusions clearly, and list the main assumptions, constraints, risks and dependencies on other work. Name the people whose time the project will need, so their managers can confirm availability before approval.
Approving and Using the Charter
Review the draft with key stakeholders to surface disagreements before approval, not after work has started.
Have the sponsor formally approve the charter and record it in the portfolio, often through a project intake or PPM tool.
Refer back to the charter when assessing change requests and at major reviews, and update it formally if the project's objectives, scope or budget change significantly.
Examples of the Project Charter in Strategic Portfolio Management
The examples below show project charters in practice.
Both use illustrative figures. The first resolves a disagreement early, and the second controls scope.
In each, writing the essentials down changed how the project was run.
Resolving a Disagreement Early
A hospital plans a project to introduce online appointment booking. While drafting the charter, the project manager finds that the sponsor expects all departments to be included, while the IT team has planned for three.
The charter review brings the issue to the surface, and the sponsor agrees to a first phase covering five departments, with a budget of $1.2 million.
The project launches on schedule, and the remaining departments are added in a second phase with its own charter.
Controlling Scope
A manufacturer's project to upgrade its warehouse system receives 40 requests for additional features during delivery.
The project manager assesses each request against the charter's scope and objectives, accepting 12 that support the stated goals and deferring the rest to a later release.
The project finishes within 5% of its approved budget, while a similar project two years earlier, run without a charter, had overrun by about 40%.
Conclusion
A project charter formally authorizes a project and records its purpose, objectives, scope, stakeholders, budget, timeline and the project manager's authority. It sits between the business case and the detailed project plan.
In strategic portfolio management, the charter links each project to strategy, reduces scope creep and clarifies accountability. Agreeing the essentials with the sponsor, writing measurable objectives, keeping the document short, approving it formally and referring back to it when changes are proposed help projects start with a shared understanding of what they must deliver.
