--- name: business-case-builder description: "Build business cases with cost-benefit analysis, ROI calculations, risk assessment, implementation timeline, and stakeholder analysis" --- # Business Case Builder ## Overview Develop compelling business cases that justify investments, align stakeholders, and enable informed go/no-go decisions. Comprehensive business cases combine financial analysis, risk assessment, and strategic alignment to make the case for action. ## Core Components ### 1. Executive Summary - **Investment Required**: Total cost in dollars and timeline - **Expected Benefit**: Quantified returns (revenue, cost savings, efficiency) - **ROI**: Payback period, IRR, NPV - **Strategic Alignment**: How this supports company goals - **Recommendation**: Proceed / Proceed with conditions / Do not proceed ### 2. Problem Statement - **Current State**: What's broken or missing today - **Impact**: Business cost of status quo (missed revenue, inefficiency, risk) - **Why Now**: Urgency drivers and market windows - **Success Criteria**: How we'll measure improvement Example: ``` Problem: Manual invoice processing takes 40 hours/week, error rate 3%, 60-day payment cycle Impact: $180K annual cost in labor + 2% revenue impact from late payments Why Now: Volume growing 25% YoY; competitors process faster Success: Automate 80% of invoices, reduce cycle to 10 days, <0.5% errors ``` ### 3. Solution Overview - **Proposed Approach**: High-level solution design - **Key Features**: Core capabilities and benefits - **Differentiation**: Why this solution over alternatives - **Implementation Path**: Phased rollout or big-bang ### 4. Financial Analysis **Cost Structure**: ``` Category | Year 1 | Year 2 | Year 3 | Total ---------|--------|--------|--------|------- Software License | $50K | $60K | $70K | $180K Implementation | $100K | $0 | $0 | $100K Training | $20K | $5K | $5K | $30K Support/Maintenance | $30K | $35K | $40K | $105K Total Cost | $200K | $100K | $115K | $415K ``` **Benefit Stream**: ``` Category | Year 1 | Year 2 | Year 3 | Total | Type ---------|--------|--------|--------|-------|------- Labor Savings | $140K | $140K | $140K | $420K | Hard Improved Collection | $30K | $50K | $50K | $130K | Hard Reduced Errors | $10K | $10K | $10K | $30K | Soft Faster Reporting | $0K | $20K | $20K | $40K | Soft Total Benefit | $180K | $220K | $220K | $620K | ``` **Financial Metrics**: - **Net Present Value (NPV)**: Benefits - Costs (discounted at 10%) - Year 1: $180K - $200K = -$20K - Year 2: $200K / 1.1 = $182K - $100K = $82K - Year 3: $220K / 1.21 = $182K - $115K = $67K - **Total NPV**: ~$131K - **ROI**: (Total benefit - Total cost) / Total cost - ($620K - $415K) / $415K = 50% total ROI - Payback period: ~15 months - **Internal Rate of Return (IRR)**: Break-even discount rate = 22% **Sensitivity Analysis**: ``` Scenario | Impact | Cost | Benefit | ROI ----------|--------|------|---------|----- Base Case | 1.0x | $415K | $620K | 50% Pessimistic | 0.8x | $450K | $500K | 11% Optimistic | 1.2x | $400K | $750K | 88% Delayed 6 Mo | Impact | $435K | $580K | 33% ``` ### 5. Risk Assessment **Risk Matrix**: ``` Risk | Probability | Impact | Mitigation | Owner -----|------------|--------|-----------|------- Scope Creep | High | Medium | Change control process | PM Adoption | Medium | High | Extensive training | HR/PM Integration | Low | High | Technical POC pre-sales | Tech Vendor Risk | Low | High | Service level agreements | Procurement Delayed ROI | Medium | Medium | Phased implementation | Finance ``` ### 6. Implementation Timeline ``` Phase | Duration | Deliverables | Risks | Dependencies -------|----------|-------------|-------|--------------- Discovery | 4 weeks | Requirements, design | Requirements change | Exec sponsorship Setup | 6 weeks | System config, data migration | Data quality | IT resources Pilot | 4 weeks | Pilot results, training | Low adoption | Vendor support Rollout | 8 weeks | Full deployment, supportGitHub で全文を読む (外部ページ)
