Web Application Development Business Case
This is a practical guide to building a business case for a web application development project — the justification that weighs the costs, benefits and risks of doing the project, adapted to the realities of building a custom web application.
What a Business Case is
A business case is the justification that weighs the costs, benefits and risks of doing the project. For the full concept and how it works in general, see Business Case. On a web application development project it plays the same role, tuned to this kind of work.
Why it matters for a Web Application Development project
Web Application Development projects live or die on building a custom web application. A well-built business case gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how web application development projects drift into avoidable delay and cost.
What to include
- Problem or opportunity
- Options considered
- Costs and benefits
- Financial appraisal (ROI/NPV/IRR)
- Recommendation
Web Application Development-specific considerations
Tailor the business case to the risks that most often derail web application development projects:
- Unclear or shifting requirements
- Technical debt
- Security and performance at scale
Example
On a real web application development project, the business case would be shaped by building a custom web application. In particular, it should explicitly account for the project’s biggest risks — unclear or shifting requirements, technical debt, security and performance at scale — rather than treating them as afterthoughts.
