Standard : Investment Allocation Ratio
Description
Investment Allocation Ratio measures the percentage of engineering and product capacity allocated to different work types — for example, features, technical debt, maintenance, and innovation. It ensures the portfolio is balanced to maximise long-term value.
This metric is essential for avoiding feature-factory behaviour and ensuring enough capacity is reserved for sustaining engineering and innovation.
How to Use
What to Measure
- Total effort (story points, hours, or capacity %) spent on each work type.
- Compare against agreed target allocation (e.g. 50% features, 20% tech debt).
Investment Allocation Ratio (%) = (Effort Spent on Category ÷ Total Effort) × 100
Example: 200 story points delivered, 40 points for tech debt → 20% allocation.
Instrumentation Tips
- Tag backlog items by work type in Jira or your tracking tool.
- Review allocation per sprint, quarter, or program increment.
- Align categories with portfolio planning process.
Why It Matters
- Sustainability: Prevents neglect of maintenance and debt.
- Strategic alignment: Ensures resources go where they create the most value.
- Transparency: Helps leadership make informed trade-offs.
Best Practices
- Agree target allocations per value stream or portfolio.
- Visualise allocations in portfolio dashboards.
- Rebalance quarterly to respond to strategy shifts.
Common Pitfalls
- Inconsistent tagging of backlog items.
- Treating targets as static rather than adaptive.
- Over-indexing on features at the expense of long-term health.
Signals of Success
- Allocation trends match strategic intent over time.
- Reduced unplanned work due to proactive debt management.
- Predictable capacity reserved for innovation.
