"Make it measurable" is the most common feedback on a draft goal, and one of the least explained. A goal is measurable when you and someone else would agree, without arguing, whether it was achieved. That can be a number, but it does not have to be.
Three ways to make a goal measurable
1. Quantity or rate. The classic metric: revenue, response time, error rate, number of clients. Use this when the data already exists and is trusted.
2. Milestone or deliverable. For projects and one-off improvements, the measure is completion of a defined output: "New onboarding guide published and used for all hires from 1 May". Being specific about "done" is what makes it measurable.
3. Observable evidence or feedback. For skills and behaviours, measure what others can see: stakeholder feedback scores, number of presentations delivered, a manager's rating against agreed criteria.
Measuring soft-skill goals
Soft skills are where people give up on measurement. You do not need to. "Become a better communicator" becomes measurable when you add evidence:
- Run the weekly team update for a quarter.
- Ask three colleagues for feedback using the same three questions at the start and end.
- Reduce follow-up clarification emails after your project briefs.
More examples are in soft skill goals examples.
Pick a baseline and a target
A measure means little without a starting point. Before setting a target, find out where you are today. "Reduce onboarding time to 10 days" is only ambitious if it currently takes 20. If there is no baseline, make your first goal "establish the baseline by month two".
Did you know? "When a measure becomes a target, it ceases to be a good measure" is known as Goodhart's law. The popular wording comes from anthropologist Marilyn Strathern in 1997, summarising a point economist Charles Goodhart made in 1975.
Watch out for gaming
Once a number becomes a goal, people find ways to hit the number rather than the purpose. Call handlers rush calls to cut handling time. Sales teams discount heavily to hit volume. Protect against this by pairing measures: speed with quality, volume with margin, output with customer feedback.
Measure progress, not just the finish
A good measurable goal has checkpoints. If your target is a 20% improvement by December, decide what "on track" looks like in March, June and September. That turns measurement into a steering tool rather than a verdict. See how to track progress on your work goals.
The bottom line
A goal is measurable when success is unarguable. Use numbers where they are meaningful, deliverables for projects and observable evidence for skills. Always set a baseline and pair metrics to avoid gaming. KPI design is a core module in our Business Planning and Goal Setting course.
