Measuring platform ROI without vanity metrics: DORA + reliability + cost - Shalini Sudarsan

Platform engineering teams often struggle to justify their return on investment (ROI) because they rely on vanity metrics like ticket counts or adoption rates rather than business outcomes. A defensible ROI framework centers on three pillars: DORA metrics for delivery speed, reliability for risk exposure, and FinOps for cost efficiency. Transitioning from a medium to an elite DORA performer can unlock 15-25% of engineering capacity, effectively providing an organization with seven to twelve additional full-time engineers without increasing headcount. By calculating the sum of capacity unlocked, incident costs avoided, and cost efficiency deltas—then subtracting the platform investment—teams can present a clear financial narrative to leadership. Implementing this strategy requires a disciplined 90-day plan focused on instrumenting data, establishing a 90-day rolling baseline, and publishing quarterly reports that prioritize outcomes over activities.
