Cost-Benefit Analysis Templates

Cost-benefit analysis templates provide structured frameworks for evaluating the financial and strategic value of experiments to prioritize optimization efforts and resource allocation. These templates transform abstract optimization opportunities into concrete business decisions by quantifying costs, benefits, and return on investment.

The Prioritization Challenge

Why Experiments Need Business Justification

Common Experiment Scenarios:

• Multiple opportunities: 20 potential optimizations, limited resources
• Unclear value: Which experiments will have the biggest impact?
• Resource constraints: Budget and team capacity limitations
• Strategic alignment: Which experiments support business goals?

Without CBA templates:

• Gut-feeling decisions: Subjective prioritization without data
• Resource waste: Investing in low-impact experiments
• Missed opportunities: Overlooking high-value optimizations
• Stakeholder confusion: Unclear rationale for experiment choices

With CBA templates:

• Data-driven decisions: Objective prioritization based on business value
• Resource optimization: Focus on highest-impact experiments
• Clear communication: Transparent rationale for stakeholders
• Strategic alignment: Experiments that support business objectives

Core CBA Framework

Basic Cost-Benefit Formula

ROI = (Benefits - Costs) / Costs × 100%

Where:

• Benefits: Revenue increase, cost savings, strategic value
• Costs: Development, testing, implementation, opportunity costs
• ROI: Return on investment percentage

Extended CBA Framework

Net Present Value = Σ(Benefits - Costs) / (1 + r)^t

Where:

• NPV: Net present value of experiment
• r: Discount rate (cost of capital)
• t: Time period (months/years)

Common Pitfalls and Solutions

Cost Underestimation

Hidden Costs

• Problem: Missing indirect costs like opportunity costs
• Solution: Include all cost categories in CBA template
• Example: Include PM time, QA time, infrastructure costs

Scope Creep

• Problem: Experiment scope expands beyond original plan
• Solution: Define clear scope and include contingency buffer
• Example: Add 20-30% contingency to cost estimates

Benefit Overestimation

Attribution Errors

• Problem: Crediting experiment for improvements not caused by it
• Solution: Use conservative benefit estimates and attribution methods
• Example: Use incremental attribution rather than total attribution

Market Assumptions

• Problem: Assuming benefits will continue indefinitely
• Solution: Use realistic time horizons and decay assumptions
• Example: Assume benefits decay 10-20% annually

Analysis Errors

Incomplete Analysis

• Problem: Focusing only on direct costs and benefits
• Solution: Include all relevant cost and benefit categories
• Example: Include opportunity costs, strategic value, risk factors

Static Analysis

• Problem: Not considering how costs and benefits change over time
• Solution: Use dynamic models that account for time value of money
• Example: Use NPV calculations with appropriate discount rates
