When starting a new project, organizations need a solid foundation to ensure success. Two critical documents that help guide project planning and execution are the business case and the project charter. While these documents serve different purposes, they are often confused with each other.
In this blog, we will explore the differences, similarities, and importance of these two documents by covering:
What is a business case?
What is a project charter?
Project charter vs. business case: key differences
When to use each document
How the business case and project charter work together
Best practices for creating both documents
By the end of this guide, you will have a clear understanding of how to effectively use a business case and a project charter to drive project success.
What is a Business Case?
A business case is a formal document that justifies why a project should be initiated. It provides a high-level analysis of the benefits, costs, risks, and expected return on investment (ROI) for a project.
Key Elements of a Business Case
A well-structured business case typically includes:
✅ Executive Summary – A brief overview of the project’s purpose and expected benefits.✅ Problem Statement – The business challenge or opportunity that the project addresses.✅ Project Objectives – Clear goals that the project aims to achieve.✅ Cost-Benefit Analysis – A detailed assessment of the financial implications, including estimated costs and potential ROI.✅ Risks and Assumptions – Key uncertainties that could affect the project’s success.✅ Alternatives Considered – Other potential solutions that were evaluated before selecting this project.✅ Recommendation – The final decision on whether or not to proceed with the project.
Purpose of a Business Case
Justifies project approval to senior management or stakeholders.
Helps decision-makers determine if the project is worth the investment.
Aligns the project with business goals and strategic objectives.
Provides a cost-benefit analysis to evaluate financial feasibility.
A business case is often created before the project officially starts and is reviewed by stakeholders who have the authority to approve or reject the project.
What is a Project Charter?
A project charter is a formal document that authorizes the project and defines its scope, objectives, and key stakeholders. It serves as a reference document throughout the project lifecycle.
Key Elements of a Project Charter
A strong project charter includes:
✅ Project Title and Description – A brief summary of the project.✅ Project Objectives – The specific goals that the project will achieve.✅ Scope Statement – Defines what is included (and excluded) in the project.✅ Key Stakeholders – Identifies sponsors, team members, and other key individuals.✅ Project Deliverables – The tangible or intangible results expected from the project.✅ Project Timeline – High-level milestones and deadlines.✅ Budget Overview – Estimated costs and resources required.✅ Roles and Responsibilities – Defines who is responsible for what.✅ Project Risks and Assumptions – Identifies potential challenges and considerations.✅ Approval and Authorization – Signatures from project sponsors to officially start the project.
Purpose of a Project Charter
Formally authorizes the project and assigns responsibilities.
Provides a high-level overview of the project’s scope, objectives, and key details.
Serves as a reference document for all stakeholders.
Helps prevent scope creep by clearly defining what is included in the project.
The project charter is created after the business case and is usually developed by the project manager, with input from key stakeholders.
Project Charter vs. Business Case: Key Differences
While both documents play a crucial role in project management, they serve different purposes. Below is a comparison of the project charter vs. business case:
Aspect | Business Case | Project Charter |
Purpose | Justifies the need for the project and evaluates its financial viability | Formally authorizes the project and defines its scope |
Timing | Created before project approval to assess feasibility | Created after project approval to initiate and guide execution |
Key Audience | Senior management, executives, financial decision-makers | Project team, sponsors, stakeholders |
Content | Focuses on why the project should be done (cost-benefit analysis, ROI, risks) | Focuses on how the project will be executed (scope, objectives, deliverables) |
Decision Making | Helps decision-makers determine whether to approve the project | Gives the project manager authority to begin work |
Flexibility | Can be modified if business priorities change | More rigid once the project begins |
When to Use Each Document
Use a business case to determine whether a project should be undertaken.
Use a project charter once the project has been approved to define its execution.
How the Business Case and Project Charter Work Together
Even though the business case and project charter serve different purposes, they are closely linked:
The business case provides the justification and financial analysis needed for project approval.
The project charter builds upon the business case by providing detailed execution plans and assigning roles.
Both documents help ensure that the project aligns with business goals and stakeholder expectations.
Think of the business case as the "why" and the project charter as the "how."
Best Practices for Creating a Business Case and Project Charter
Business Case Best Practices
✔ Be Clear and Concise – Avoid unnecessary complexity; focus on the key benefits and costs.✔ Include Data and Evidence – Use market research, case studies, or financial projections to support your justification.✔ Consider Multiple Scenarios – Compare different approaches and explain why your chosen solution is the best.✔ Engage Stakeholders Early – Get input from finance, operations, and leadership to ensure alignment.✔ Use Visuals – Charts and graphs can help illustrate financial projections and cost savings.
Project Charter Best Practices
✔ Clearly Define Scope – Avoid scope creep by outlining project boundaries.✔ Specify Measurable Objectives – Use SMART (Specific, Measurable, Achievable, Relevant, Time-bound) goals.✔ Identify Key Stakeholders – Ensure all roles and responsibilities are well-documented.✔ Keep It High-Level – The project charter should be a summary, not a detailed project plan.✔ Secure Executive Buy-In – Get formal approvals from sponsors before starting work.
Agile Project Charter: A Guide to Project Success
In Agile project management, a Project Charter serves as a high-level document that defines the project's purpose, objectives, and key stakeholders. Unlike traditional project charters, which are highly detailed and rigid, an Agile Project Charter is lightweight, flexible, and focused on guiding teams through an iterative and adaptive process.
An Agile Project Charter typically includes:✅ Project Vision – A clear statement of what the project aims to achieve.✅ Objectives and Goals – High-level, outcome-driven targets aligned with business value.✅ Scope Overview – A broad definition of what is included, allowing for flexibility.✅ Key Stakeholders – Identifies the product owner, Scrum Master, and development team.✅ Success Criteria – Defines what success looks like for the project.
Unlike traditional project management, Agile frameworks (Scrum, Kanban, SAFe) emphasize continuous learning and adaptation. The Agile Project Charter is not a static document but evolves with the project. It empowers teams with autonomy, collaboration, and shared accountability, ensuring alignment with business goals while allowing for change and innovation.
A well-crafted Agile Project Charter helps teams stay focused, fosters agility, and ensures that everyone is working toward a common vision. 🚀
Final Thoughts
Understanding the project charter vs. business case is essential for effective project planning and execution. While the business case provides the justification for starting a project, the project charter serves as the official authorization document that guides execution.
By using both documents correctly, organizations can improve project success rates, reduce risks, and ensure alignment with business goals.
If your organization struggles with project planning, start by creating a well-structured business case and project charter to set your team up for success! 🚀
