Define Success Criteria That Steer Project Decisions and Deliver Results

Establishing project governance
Written By Stephen Reed

Strong success measures help you lead with confidence, deliver with focus, and finish with proof.

Every large project is launched with good intentions, but intentions don’t drive results. If you want to show that your initiative is contributing toward the bigger-picture — and help the team make better decisions along the way — you need to define what success looks like from the start.

Why Success Criteria Matter More Than You Think

Launching a project doesn’t mean that it succeeded, or that it met the original objectives you set out to achieve. That’s why success criteria are so powerful:

  • They can build confidence with project sponsors by showing that you understand what matters.

  • They define for the team how they’re going to be judged.

  • They steer decisions during the project, preventing wasted effort on features that don’t move the needle.

  • They can highlight that the team accomplished what they set out to achieve.

Strong success criteria turn fuzzy ambitions into clear outcomes. As you can guess from the above, they’re not just for the end of the project. When you define success early on, your whole team has a shared understanding of where you need to go.

Quick Tips for Writing Strong Success Criteria

Strong success criteria are meaningful, measurable, and actionable:

  • Tie them to the objective. They should directly answer: “How will we know we achieved the goal?” If you can’t draw a line between the success measure and the objective, it probably doesn’t belong.

  • Limit to 3–5. Focus on a few meaningful indicators. Too many and you dilute focus — too few and you may miss some important nuances.

  • Establish a baseline. Without a clear before-state, it can be impossible to prove real progress. Try to baseline your success measures before launch (or right after) so you can compare performance over time.

  • Measure outcome instead of output. Saying “we launched the system” isn’t the same as proving it changed behavior or improved results. Look for metrics that capture impact: are users actually engaging, converting, or returning more frequently?

  • Include guardrails. Consider what shouldn’t decline (like customer satisfaction or gross margin). A success measure that increases at the cost of something else may not be a true win.

Common Pitfalls to Avoid

  • Picking what’s easy to measure instead of what matters
    Some of the most important business outcomes are harder to track. Don’t default to simple metrics if they don’t represent success. That’s why it’s worth defining these early — so you have time to build and track what really matters before you launch.

  • Neglecting segmentation
    Aggregate results often mask issues or hide key insights. Success in one market, team, or customer type may be hiding underperformance somewhere else. Plan to drill down and understand the segments that are contributing to (or holding you back from) key results.

  • Ignoring leading indicators
    Waiting until weeks or months after post-launch to measure success often means it’s too late to course-correct. Mix in early signals (like adoption or usage) to show whether you’re on the right track.

A Real-World Example of Quality Success Measures

Here’s how the above principles can come together in practice:

Objective: Implement a gamified loyalty program with personalized rewards, interactive challenges, and tiered incentives to strengthen customer engagement and increase repeat visits — while maintaining alignment with our brand’s family-focused storytelling experience. The solution should be intuitive to use and supported by clear onboarding and feedback mechanisms to avoid confusion and encourage sustained participation.

Success Criteria:

  • Achieve 30% loyalty program adoption among eligible customers within 9 months

  • Drive 3+ loyalty interactions per user per month

  • Increase repeat visits among loyalty members by 15% within 6 months

  • Maintain or improve NPS among loyalty members

  • ≥80% of surveyed members say the program is easy to understand and use
