The first formal document I ever signed as a project manager was a charter, and I still remember the meeting room. It was on a wet October morning, my sponsor was running ten minutes late, and the charter I had drafted was four pages long with three pages of appendices. By the time the sponsor arrived, scanned the front page and signed at the bottom, I realised that 80% of what I had written would never be read by anyone other than me. That experience shaped how I have approached charters ever since.
A project charter is the formal authorisation for a project. In PMI terminology it is the output of Process 4.1, Develop Project Charter, and it is the single document that gives the project manager the authority to apply organisational resources to project activities. Without it, the project is informal, contested, and politically vulnerable. With it, the project has a foundation. In this article I will walk through what a charter contains, what it does not, why it matters far beyond the exam, two complete sample charters (one IT, one construction), and the formal sign-off rules that PMI expects you to know.
A project charter is a formal document issued by the project sponsor (or by a person or group with sufficient authority) that authorises the existence of a project and grants the project manager the authority to apply organisational resources to project activities. That definition, slightly paraphrased from the PMBOK Guide, is worth memorising because it contains every important word.
"Formal" means it is written. Verbal authorisation does not count. "Issued by the sponsor" means it does not come from the project manager. The PM may draft it, but the sponsor owns it. "Authorises the existence" means before the charter is signed the project formally does not exist. "Authority to apply resources" means the PM can now legitimately request budget, staff, and time.
"The charter is not just paperwork. It is the social contract between the sponsor and the project manager. Without it, every difficult conversation later is harder."
I have learned over the years to think of the charter as a piece of organisational architecture. It creates a boundary around the work. Inside the boundary the PM has authority. Outside the boundary they do not. Everyone, including the PM, benefits from that clarity.
Process 4.1, Develop Project Charter, is the first process in the PMBOK Guide Sixth Edition. It belongs to the Initiating Process Group and the Integration Management Knowledge Area. Its placement is deliberate: nothing else in the PMI framework happens before a charter exists.
The inputs to 4.1 are the business documents (business case and benefits management plan), agreements (especially for external projects), enterprise environmental factors, and organisational process assets. The output is the charter itself and the assumption log. The techniques used to produce it include expert judgement, data gathering (brainstorming, interviews, focus groups), interpersonal and team skills (conflict management, facilitation, meeting management), and meetings.
For the exam, you should know that the charter:
A frequent exam trap is to describe a scenario where a PM is mid-execution and discovers a missing element. The correct answer often references the charter, because the charter is the source of truth for high-level direction.
PMI does not mandate a fixed format, but the PMBOK Guide identifies content that should appear in nearly every charter. The components I include in every charter I write are:
| Component | What it contains | Typical length |
| Project purpose | Why this project exists, linked to strategy | 1 paragraph |
| Measurable objectives | What success looks like in numbers | 3 to 5 bullet points |
| Success criteria | How acceptance will be judged | 3 to 5 bullet points |
| High-level requirements | What must be delivered (not how) | 5 to 10 bullet points |
| High-level milestones | Major dates only | 4 to 8 milestones |
| Summary budget | Order of magnitude estimate | 1 line or 1 table |
| Key stakeholder list | Sponsor, PM, customer, key SMEs | 1 table |
| High-level risks | The top 5 to 10 risks | 5 to 10 bullet points |
| Assumptions and constraints | What we are taking for granted | 5 to 10 bullet points each |
| PM authority | Spending limits, hiring authority, escalation rules | 1 paragraph |
| Approval requirements | Who signs, what triggers re-approval | 1 paragraph |
| Sponsor signature | Name, title, date | 1 line |
If your charter contains all of the above and nothing else, it will pass any sensible review. If you find yourself adding detailed schedules, full requirements documents, or Gantt charts, you have moved into the project management plan, not the charter.
These three elements form the heart of the charter and the area where I see most candidates struggle. They are related but distinct.
The purpose answers "why are we doing this project?" It should connect to organisational strategy. Example: "To improve customer self-service capability and reduce contact-centre call volume by enabling online account management."
The objectives answer "what specifically will we achieve?" They must be SMART (specific, measurable, achievable, relevant, time-bound). Example: "Reduce call-centre volume by 25% within six months of go-live, measured against the rolling 12-month average."
The success criteria answer "how will we know if we succeeded?" They are the acceptance conditions. Example: "Project will be considered successful if (a) call volume reduction targets are met, (b) customer satisfaction NPS does not decline, and (c) cost remains within 10% of approved budget."
A trick I use: if you cannot distinguish a sentence as a purpose, objective, or criterion, it is probably none of them and should be cut. Charters bloat when sentences blur these categories.
These three sections give the charter its physical shape. The PM will refine each later, but the charter establishes the order of magnitude.
High-level requirements are not detailed user stories. They are statements of what must exist for the project to be considered complete. Example: "The system must support secure login, account balance display, statement download, and payment scheduling."
High-level milestones are not a full schedule. They are the four to eight dates the sponsor cares about. Example:
The summary budget is an order-of-magnitude estimate, often with a stated accuracy range (e.g., minus 25% to plus 75%). It is not a detailed cost baseline. Example: "Estimated total cost: 1.8 million GBP, plus or minus 30% at charter stage. Cost baseline to be established in Planning."
The stakeholder list at charter stage is short. It identifies the sponsor, project manager, customer (if external), and the four or five most senior or influential people. A full stakeholder register comes later in the Identify Stakeholders process.
High-level risks are the top five to ten things the sponsor needs to know about. Example: "Risk of vendor delivery slippage due to ongoing supply-chain disruption" or "Risk of resource contention with parallel programme."
Assumptions are things the PM is taking as true without proof. They should be tracked because if any prove false, the project is at risk. Example: "We assume the existing identity provider can be reused without modification."
Constraints are limitations the PM cannot change. Example: "The project must go live before the end of the financial year for regulatory compliance reasons."
I keep all four sections short at charter stage. The detail comes later. The charter exists to flag, not to resolve.
This section is often missing from charters I review and it is the single most useful section to get right. It defines what the PM can do without further approval.
Specific elements I include:
A charter without explicit PM authority creates ambiguity that haunts the project. I have seen PMs lose months to political battles that a single paragraph in the charter would have prevented.

The charter is not a one-time document filed away after signature. I keep it visible throughout the project and refer to it frequently. Specifically:
"If you cannot remember what was in your own charter by the time you are halfway through execution, your charter is too long, your project is off the rails, or both."
The charter also matters at closure. The closure report typically restates the original objectives and success criteria and reports against each. A clear charter makes closure straightforward. A muddy charter makes closure contentious.
PMI is specific about charter approval. The sponsor signs the charter. Not the project manager. Not a committee. The sponsor.
In practice, charters are often counter-signed by other parties (the PM, the customer, the finance director, the CTO) but the controlling signature is the sponsor's. If the sponsor changes mid-project, a fresh charter or a formal endorsement of the existing charter by the incoming sponsor is good practice.
Re-approval is required when material changes occur. Material change is judged against the original objectives. Examples:
Minor changes do not require re-charter, but should be documented as charter addenda or via the change control process described in the project management plan.
In Agile and hybrid contexts, charters are often lighter (sometimes called a "project brief" or "vision document") but the formal authorisation principle remains. Someone with authority must explicitly authorise the work.
I want to be honest about my own mistakes because they tend to repeat across PMs.
If you can avoid these five mistakes, your charters will be in the top quartile of those I have seen in audits.
Agile projects still need a charter, but the form and emphasis differ. In a Scrum-based programme I worked on a few years ago we used a one-page "Product Vision and Charter" that included:
We did not include detailed requirements (those lived in the backlog), nor a fixed scope (the backlog evolved). What mattered was the formal authorisation and the clarity around decision rights. The product owner's authority to prioritise the backlog was explicit in the charter.
For hybrid projects, I tend to include a fixed-scope element (the "must have") and an evolving element (the backlog). The charter authorises both, with different governance for each.
Practical templates I have used and recommend:

QUICK FACTS
The project manager typically drafts the charter, but it is issued and signed by the sponsor. The sponsor owns the charter and the authorisation it confers.
