Which metrics tell the truth about your project?
Good KPIs for a development project measure delivered value, not activity. Track delivered functionality against plan, bug trends over time, and how predictably the team delivers. Avoid hours and lines of code – they measure effort, not results. A handful of robust metrics in a simple monthly report is enough for a client to see whether a project is on track.
As a client, you want to know one thing: is the project heading in the right direction? The problem is that the development world offers a glut of metrics, and most of them are made for the developers’ own work – not to give you the answer. Choose the wrong metrics and you drown in numbers that look impressive but say nothing. Choose the right ones and a handful of metrics is enough to sleep soundly at night.
Metrics that measure value, not activity
The basic rule is simple: measure what’s been done and works, not how much has been worked. A handful of robust metrics is enough.
- Delivered functionality against plan. How much of what was planned for this period is actually done, tested, and approved? It’s the closest you’ll get to a true measure of progress.
- Bug trend. The number of known bugs and, more importantly, whether the trend is up or down. Falling bug counts mean quality is being built in; rising ones are an early warning sign.
- Predictability. Does the team roughly deliver on what it commits to from period to period? A team that delivers evenly is easier to plan around than one that swings wildly, even if the erratic one sometimes delivers more.
- Risk overview. Not a figure, but a short list of what could upend the plan. Risks surfacing early is in itself a sign of a mature project.
These metrics have one thing in common: you can’t fake them just by working harder. They reflect results.
The metrics that are theater
Some numbers look like they measure progress but don’t. The most common are hours spent and lines of code.
Hours measure effort, not results. A team can show full utilization and still have built the wrong thing, or spent the week fixing its own mistakes. Hours are a cost metric, not a progress metric – treat them accordingly.
Lines of code are even worse, since they reward exactly the wrong behavior. More code means more to maintain and more places for errors to hide. Often the most skillful solution is the one that solves the problem with the least code. Measuring lines of code is like judging a writer by page count.
Watch out for “health scores” that are always green. If every report shows everything is on plan, right up until the week everything is suddenly delayed, the report is measuring appearances rather than reality.
A concrete example
Picture two monthly reports for the same project. One says: “The team has logged 320 hours, written 12,000 lines of code, and morale is good.” The other says: “Of the six features planned, four are done and approved, one is delayed due to an unexpected integration, and the number of open bugs has gone from 18 to 11. The biggest risk ahead is the payment provider’s testing.”
The first sounds busy but leaves you just as in the dark as before. The second is shorter, but now you know exactly where the project stands, what’s rubbing, and what you might need to decide on. That’s the difference between measuring motion and measuring direction.
A simple report template to require
You don’t need to specify advanced dashboards. Instead, ask for a short monthly report that answers four questions:
| Question | What you get |
|---|---|
| What got done against plan? | Actual progress |
| What's the bug status and trend? | Quality over time |
| What risks are visible ahead? | Early warning |
| What happens next? | Direction and expectations |
If the report fits on one page, it’s about right. The goal is material for decisions, not a stack that impresses but no one reads.
At Weapp, we work in short cycles with open reporting precisely so you see the direction early, not get surprised late. Want that visibility in your project? Read more about our services or get in touch with a short description of what you want to build.
Frequently asked questions
Why are hours spent a poor metric?
Hours measure how much has been worked, not what's been accomplished. A team can spend hundreds of hours on the wrong things, or fixing its own mistakes, and still show full utilization. Hours tell you something about cost, but nothing about progress or value. Track instead what's actually been delivered and works.
Are lines of code a measure of productivity?
No, quite the opposite. More lines of code often mean more code to maintain and more places where errors can occur. Often the best solution is the one that requires the least code. Measuring lines of code rewards the wrong behavior and says nothing about whether the product does what it's supposed to. Avoid it entirely as a governance metric.
Which metrics are enough for a non-technical client?
Three to four go a long way: delivered functionality against plan, the number of open bugs and whether it's rising or falling, and how well the team holds to its commitments per period. Add a short risk overview. More metrics rarely lead to better decisions, just more to interpret and easier to hide behind.
What is bug trend, and why does it matter?
Bug trend is how the number of known bugs changes over time. A decreasing number suggests quality is being built in; a steadily increasing number is an early warning that debt is building up under the surface. The trend says more than any single figure – a short rise ahead of a launch can be completely normal.
How often should I get a report?
Monthly is enough for most projects, with shorter check-ins in between if something requires a decision. The report should be short and understandable – what's been delivered against plan, the bug status, the risks, and what happens next. If the report turns into a thick stack of paper, it has become theater instead of a decision-making tool.
