Business case: definition, purpose, structure, and examples
Key takeawaysSelect your preferred qualification or workshop.
A strong business case turns a proposal into a decision by making value, costs, and risk explicit.
- Use a business case when resources are limited and there are credible alternatives, including a do-nothing baseline.AIPGF COURSES
- Make roles clear: an author drafts, finance and risk challenge, and an executive sponsor owns benefits and alignment.Select your preferred training course below:
- Anchor the case in a measurable baseline, defined objectives, and KPIs so outcomes can be tracked after delivery.
- Compare options transparently using full costs, quantified benefits, and appraisal methods such as ROI, NPV, IRR, and payback.BCS AI COURSES
- Separate risks, assumptions, constraints, and dependencies, and include mitigations and a post-implementation review plan.Select your preferred training course below:

Decision-makers need to understand what could undermine delivery or benefits. Good business cases separate:Estonia
- AssumptionsFinland: statements treated as true for planning (for example, adoption rates or volume growth).France
- ConstraintsGermany: fixed limits (for example, deadlines, budget caps, mandated technology).Greece

Estimated annual benefits
- Time saving: 40 users x 2 hours/week x 52 weeks x 60% x GBP 35/hour = GBP 87,360 per year.
- Revenue uplift:Copied! GBP 60,000 per year.Key takeaways
- Total benefits:A project communication plan sets out who needs what information, when, and how it will be shared. GBP 147,360 per year.Start with stakeholder analysis so messages match each group’s needs, influence, and preferred channels.
- Net annual benefit after licences:Set measurable communication goals, then track signals like response times, attendance, and stakeholder satisfaction. GBP 147,360 minus GBP 24,000 = GBP 123,360 per year.Balance regular updates with information overload by aligning cadence to milestones and urgency.
Simple ROI, payback and NPV illustrationAssign clear communication responsibilities so reporting, meetings, and documentation are consistently owned.
- Initial investment (year 0):Use templates, visuals, and project tools to keep messaging clear, consistent, and easy to action. GBP 55,000.Review and adapt the plan as scope, risks, cultures, time zones, and team set-ups change.
- Payback period: GBP 55,000 divided by GBP 123,360 is about 0.45 years (about 5 to 6 months).
- Simple ROI (year 1): (GBP 123,360 minus GBP 55,000) divided by GBP 55,000 is about 124%.Contents
- NPV (3 years, 8% discount, simplified): NPV = -55,000 + 123,360/(1.08) + 123,360/(1.08^2) + 123,360/(1.08^3) = approximately GBP 262,000.
Interpretation:Contents Under the stated assumptions, the business case supports approval because value is positive, payback is short, and risks can be mitigated through adoption and data-quality controls. In practice, include sensitivity analysis (best case, expected, worst case) for decision confidence.

- ReviewA successful project communication plan requires clearly defined goals and objectives as its foundational elements. The communication plan goals need to support the project’s main objectives while fulfilling requirements. A fundamental objective of the communication plan should be delivering regular updates to all stakeholders. The objectives for project communication could focus on decreasing email response times and boosting attendance at project meetings. Create : finance and subject experts challenge costs, benefits, and assumptions; risks and constraints are refined.quantifiable goals

- Post-implementation review to determine which groups and individuals are part of or affected by your project. Key stakeholders consist of team members as well as clients, sponsors, and external partners.
