5 Steps to Confidently Quantify Initiative Benefits
Gartner®’s Research
A 5-step methodology to help you defend your investment decisions with evidence.

Benefit Quantification Is Now a Core Portfolio Capability
Under rising cost pressure and increased scrutiny, portfolio leaders must show clear, validated impact before capital is allocated. Inconsistent calculations and disconnected business cases make that difficult.
This research outlines a practical framework to structure outcomes, establish baselines, estimate improvement, and calculate ROI so funding decisions are grounded in measurable impact.
Our Key Takeaways:
- How to apply Gartner®’s Five “Whats”: outcome, metric, baseline, improvement rate, and ROI, to structure defensible benefit calculations.
- When not to quantify benefits, and why some outcomes such as compliance and cybersecurity are critical but may not translate to measurable financial returns.
- How to establish credible baselines and estimate improvement rates realistically using representative data, benchmarks, and leadership targets.
- How to calculate ROI using total cost of ownership (TCO) and validate financial assumptions with finance partners.
- How to standardize benefit rules, tracking, and reporting so programs and projects are comparable, credible, and visible as they roll up toward strategic goals.
