The Power of a Project Charter: Purpose, Creation, and Best Practices

What is a Project Charter?

A project charter is a formal document that establishes the existence of a project and grants the project manager authority to expend organizational resources on project deliverables and objectives. This is the PMBOK definition, which views a project charter as one of the initial processes of a project's Initiating phase.

Unlike many other project-management documents, a project charter is supposed to be brief — ideally, one to three pages in length. It serves as a starting point for a project, providing a high-level overview of what the project will and will not accomplish. It should be completed before any other planning processes take place, serving as the foundation for a project. Unlike other documents, such as a project plan, a charter serves as a formal declaration that the project has been approved for initiation, which is why its creation is so critically important.

The terms "charter," "business case," and "project plan" are often conflated in project management, so comparing them is a good idea: 

Document	Purpose	Created When	Owned By	Length
Business Case	Establishes that a project should happen, based on ROI, cost/benefit analysis, and strategic fit	Before project initiation	Sponsor and/or finance team	Varies, often several pages
Project Charter	Formally authorizes the project and defines its high-level goals, scope, and management authority	Immediately after approval, when planning begins	Sponsor, signed off by project manager	1–3 pages
Project Plan	Describes how the work will be done in detail; includes schedules, assignments, budget, etc	When planning begins, after the charter is created	Project manager	Often dozens or hundreds of pages

A few simple observations can be made from this comparison. First, a business case is created by the sponsor and/or finance team long before the project can formally begin, whereas a charter is created immediately after a project's approval and serves as the foundation for the creation of the rest of the project's documents. Second, it is critically important that a business case, charter, and project plan be created in this particular order, without skipping between them, as doing so will lead to the majority of scope-creep and stakeholder dissatisfaction issues down the road. 

The Real Purpose of a Project Charter

A project charter serves a variety of essential functions in a project, most of which stem directly from its definition.

• Authorization and PM authority: A project charter is the only method of formally authorizing a project, which means that every time a project manager attempts to utilize the organization's time, money, or human resources, they will be questioned in terms of whether this expenditure is explicitly approved by the sponsor.
• Alignment: Because a project charter is created jointly between a project manager and stakeholders, it serves as an early opportunity to identify and resolve disagreements regarding what a project should and should not deliver.
• Scope creep prevention: A project charter is the only document that formally lists what a project will and will not include, which makes it the best tool for resolving new requests for additional deliverables. With 70% of all projects suffering from some form of scope creep, the value of this function cannot be understated.
• Strategic benefit: A project charter provides the project scope with a strategic benefit, linking it to an objective in order to ensure that the project continues to be prioritized when company priorities change.

These functions are deeply intertwined with each other: a charter's mere existence serves as a form of authorization, but if the conflicting project needs are not aligned, the value of that authorization is significantly reduced. A project with aligned needs but no strategic benefit is one that the stakeholders will value in the short term but that lacks long-term viability. All the functions of a project charter serve together to increase the chances of a project's success, which is why skipping its creation is rarely a wise decision.

Key Elements of an Effective Charter

As mentioned, a project charter is not a long document, but there are certain essential elements that, when expanded upon, provide the project with the necessary structure to ensure its viability. These elements are as follows:

• Project's purpose and justification: A description of the problem this project is supposed to solve or the opportunity it is supposed to capitalize on, as this serves as the project's justification.
• Objectives: The specific project deliverables, preferably written as SMART goals if possible.
• Scope: A description of what the project will and will not include, as previously mentioned the most crucial tool for avoiding scope creep.
• Stakeholders: A list of all the stakeholders for this project, along with their roles and areas of responsibility.
• Budget, cost estimate, and resources: An overview of the project's costs, as well as the resources it will require.
• Timeline and milestones: An overview of the project's timeline, divided into clearly defined milestones.
• Risks and assumptions: A list of risks associated with the project, as well as the assumptions that the project planning is based on.
• Success criteria/KPIs: The measurable factors that will be used to determine the project's success.

The stakeholder list should also include a clearly defined RACI matrix, where applicable. If a project charter includes an entry for stakeholders without defining their roles in the project, it has failed to serve its basic functions.

How to Create a Project Charter: Step-by-Step

While the creation of a charter is a collaborative effort between a project manager and stakeholders, it is important to approach the task in an orderly manner, using the following steps:

1. Clarify the business problem: Before creating the charter, define which business need the project was created to address and what strategic objective it serves, as this will form the foundation for the charter. This is particularly important for the justification section.
2. Plan objectives and success criteria: Define exactly what project deliverables are required, and write them as SMART goals if possible. Since objectives are essentially the project's goals, they must be clearly defined if success criteria are to be reached.
3. Create a scope list: Define what this project will and will not accomplish — it is vital that both the included and excluded project elements are explicitly listed, as any new requests for deliverables that fall under the "excluded" category will need to be formally rejected.
4. Identify stakeholders: The stakeholders must be brought onboard and made aware of their responsibilities, as opposed to simply being given the document at the end of the process. The most frequent cause of project delays is a lack of stakeholder clarity, so this element should include a stakeholder RACI matrix, identifying who is responsible for what.
5. Define the project's budget, timeline, and risk: If possible, base the budget on similar past projects, as attempting to estimate costs from scratch is frequently inaccurate. The same applies to timelines.
6. Have the charter reviewed and sign off: The document must be formally approved, which serves to officially authorize the project.

Every element of the charter supports the next one, which is why the process of creating the document must follow a strict order. Scope is vitally important, but defining it before objectives have been reached is a pointless exercise, as the objective serves to define the scope. The same applies to stakeholder alignment: unless the stakeholders fully understand the project's scope, no meaningful alignment can take place.

Agile vs. Waterfall: Does Your Methodology Need a Different Charter?

One question that is seldom asked is whether an Agile project even requires a project charter, given that Agile methodologies lean towards adaptability. The truth is that Agile project management methods actually benefit from having a project charter, although it is frequently much more light-weight than the one used for a waterfall project. A project charter for an Agile project will typically include high-level information on the product vision, whereas a traditional charter will explicitly list every single deliverable. Agile project managers also tend to pair their charters with product vision statements or working agreements, which define how the team will operate.

Hybrid projects, as one might expect, fall somewhere in the middle: they require a charter that explicitly lists the project's constraints and approval requirements, while also being light on the details of deliverables, since Agile methods were adopted specifically to handle changing requirements. Getting this right is critically important, as PMI's Pulse of the Profession 2026 research has found that over 50% of projects are now classified as "complex" rather than "simple," and the rate at which complex projects fail to deliver their intended scope of benefits has jumped from 12% in 2024 to 31% in 2026. Failing to properly tailor the project charter to the methodology used is one reason why projects are increasingly failing to deliver their intended scope of benefits, and the correct alignment of the charter with the methodology is a key factor in reducing this failure rate.

Best Practices vs. Common Mistakes

It is much more useful to think of best practices and common mistakes in the same breath, as the two concepts are intrinsically linked. For instance, most common mistakes in creating a project charter are best practices when they are not made, which is why avoiding all common mistakes is effectively the most optimal way of creating a project charter. Here are several common mistakes that should be avoided when creating a project charter, paired with best practices: 

Best Practice	Common Mistake That It Prevents
Keep it short and simple (ideally, 1–3 pages)	Writing an unnecessarily long document that nobody reads
Collaborate with stakeholders to create the charter	Presenting a finished charter to stakeholders for their approval
Write out your goals using SMART guidelines	Having vague or unrealistic project goals that are impossible to measure
Specify exclusions	Failing to identify project scope boundaries, leading to frequent change requests
Use plain language	Compiling a document only project managers can understand
Treat the charter as a living document that guides the project	Filing the charter away and ignoring it once the project has launched
Get explicit sponsor approval for the charter	Continuing to work on the project based only on verbal approval

The common mistakes listed here are invariably the result of not following best practices, which is why "best practices" and "common mistakes" are really two sides of the same coin.

Case Study: Why This Company's Project Failed (With a Template!)

The case study below is not based on a real project, though it reflects many real-life details that can be found in PMI's requirements-management research as well as public post mortems from companies that have launched similar software projects. This composite illustrates the typical missteps that occur when a project charter is either poorly structured or entirely skipped:

A fictional 150-employee SaaS company launches a customer self-service portal with a single Slack message from the VP of Operations ("Let's get it built by the third quarter"). The project manager begins organizing the team around this goal, determining that a 5-person team is sufficient for the task, and moves on to planning the sprints for the project. Two separate issues emerge ten weeks into the project: the marketing team assumed the self-service portal would include a rewards module, which they had previously included in a roadmap presentation for the all-hands meeting; the customer support team, on the other hand, expects the portal to include multilingual support, since it was previously mentioned in another unrelated initiative. Neither team realized that this functionality had not been explicitly approved for the self-service portal project — in fact, this project did not even have a formal scope document, since the VP of Operations only approved the project verbally.

By the time these issues were discovered, it was too late to add the requested features without significant architecture reworks, which would push back the launch date by approximately six months and add $85,000 to the project's costs. It is important to note that this project was cancelled several months later and placed on indefinite hold, but not because of these issues — they were merely the proximate cause for the project's cancellation, which was ultimately the result of a 15-minute conversation that never took place because there was no document to force that conversation to happen.

A project charter's most basic use is to serve as a tool for communication, which is why its mere creation forces the project stakeholders to engage in that vital conversation. The sample charter below contains the information that, if present in this case study, would have been sufficient to prevent this project from wasting 10 weeks of development time on the architecture required to support features that the project sponsor explicitly did not want:  

Sample Charter: What Should Have Existed

Here is the one-page charter that, had it existed before the sprint planning started, would have surfaced the loyalty-module and multilingual questions in a 15-minute review instead of a 6-week rework:

Project Name	Customer Self-Service Portal (Support Deflection Initiative)
Sponsor	VP of Operations
Project Manager	[PM Name] — authorized to allocate engineering resources and approve sprint-level scope decisions
Purpose / Justification	Reduce inbound support ticket volume by giving customers a self-service portal to manage their own accounts, billing, and common troubleshooting steps. Directly supports the FY26 goal of cutting support cost-per-customer by 15%.
Objectives (SMART)	1) Launch a self-service portal covering account management, billing history, and a troubleshooting knowledge base by end of Q3 2026. 2) Reduce Tier-1 support tickets by 20% within 60 days of launch, measured against the trailing 90-day ticket average.
Scope — In	Account management (profile, password, plan changes); billing history and invoice downloads; searchable troubleshooting knowledge base; English-language UI only.
Scope — Out (explicitly excluded)	Loyalty-rewards module — deferred to a future phase; not part of this release regardless of prior roadmap mentions. Multilingual / localized support — deferred; this release ships in English only. Any expansion to either must go through a documented change request, not an assumption.
Stakeholders & RACI	VP of Operations — Accountable (sponsor, final sign-off). Project Manager — Responsible (delivery, scope enforcement). Engineering Lead — Responsible (build). Marketing — Consulted (messaging only; not scope). Customer Support Lead — Consulted (knowledge base content); Informed on release date.
Budget	$120,000 (engineering time, QA, and infrastructure), with a 10% contingency reserve for rework.
Timeline & Milestones	Kickoff: Week 1. Design sign-off: Week 3. Build complete: Week 8. QA: Weeks 9–10. Launch: End of Q3 2026.
Risks & Assumptions	Risk: stakeholders may assume features from prior roadmap conversations are included — mitigated by the Scope-Out section above. Assumption: existing billing API can support the account-management features without a separate integration project.
Success Criteria / KPIs	20% reduction in Tier-1 tickets within 60 days of launch; portal adoption by 30% of active accounts within 90 days.
Sponsor Approval	Signed: _______________________ Date: _______________

Scope conversations like this one shouldn't happen by accident — Sprintzeal's CAPM® Certification Training covers exactly this: how to structure a project from initiation onward, so it never gets this far off track.

Grade Your Own Charter: A 5-Point Maturity Scorecard + Using AI to Draft It

Before submitting a charter for sign-off, score it honestly across five dimensions, rating each from 1 (weak) to 5 (strong):

1. Clarity — Could someone outside the project team read this and understand the goal in under two minutes?
2. Stakeholder buy-in — Have the actual stakeholders reviewed and agreed to this, not just been copied on the email?
3. Measurability — Are the success criteria specific enough that success or failure will be obvious later?
4. Scope precision — Are exclusions stated as clearly as inclusions?
5. Risk coverage — Are the two or three most likely risks named, along with the assumptions they depend on?

A charter scoring below 15 out of 25 typically needs another revision pass before it goes to the sponsor.

Drafting the first version doesn't have to start from a blank page. AI tools like Claude or ChatGPT can generate a solid first draft when given the right prompt. Try something like:

"Draft a one-page project charter for [project name]. The business problem is [X]. The objective is [Y], measured by [Z]. Known stakeholders are [list]. Budget ceiling is [amount]. The deadline is [date]. Include sections for purpose, objectives, scope (in and out), stakeholders, risks, and success criteria."

This produces a structured starting point in seconds, which the team can then refine together — saving the drafting time without skipping the collaborative review that makes a charter actually work.

Frequently Asked Questions on Project Charter

1. What is the main purpose of a project charter?

A project charter formally authorizes a project and gives the project manager the authority to use organizational resources — while aligning sponsors and stakeholders on scope, objectives, and success criteria before detailed planning begins.

2. Is a project charter legally binding?

No. It's an internal authorization document, not a contract. It carries organizational weight as formal sponsor approval, but it doesn't create legal obligations the way a signed contract with an external party would.

3. Who is responsible for writing the project charter?

The project manager typically drafts it, but the project sponsor authorizes and signs it, and key stakeholders should review it before it's considered final.

4. How long should a project charter be?

One to three pages. If it's longer, it's drifting into project-plan territory — the charter should stay high-level.

5. Does a small project still need a project charter?

Yes, even a simplified one-paragraph version. The discipline of stating scope, objectives, and exclusions up front scales down just as well as it scales up, and it costs far less than the cost of resolving a scope disagreement mid-project.

6. What's the difference between a project charter and a project plan?

The charter authorizes the project and defines why it exists and what its boundaries are; the project plan is created afterward and defines how the work will actually get done — tasks, schedules, and resource assignments.
