5 Software Metrics to Keep Your Product Development on Track

If you're part of an Agile team, you now metrics are your friend. Here are 5 good metrics to keep your eye on to help you optimize your Sprint.

Whatever new awaits you, begin it here. In an entirely reimagined Jira. 


Developing a quality software product falls under the realm of software engineering. The ever changing user requirements and harsh project timelines pave the way for cost overruns or delays in the delivery schedule. So, the bigger the scope of your project, the more complex the functionality becomes. With so many factors it is very easy to lose control over the quality processes.

We know that no engineering is complete without accurate measurements; which brings us to the point that all measurements are done by applying certain metrics.

For this reason, we need software metrics for transparent and quality delivery of the product. Because when you measure what you speak about, you have numbers to express your failure or success. You have a calculated expression which shows you where you lacked and places where you did well. In Bob Parsons’ words, 'Anything that is measured and watched, improves.'

Now the question arises - which software metrics to use?

One option is to pick a set of predefined metrics. The other option is to first define the product requirements, discuss them with the various stakeholders, and then set the required metrics.

For a better understanding, consider an analogy where you are packing a bag for an adventure activity. Would you pack a parachute if you are going for kayaking?

Absolutely not.

Instead, you would first decide upon the adventure sport, do a bit of research and accordingly pack your adventure gear. So, if you are going to go paragliding, pack a helmet and a harness.

You can leave the oars behind for the next time.

For this reason, it is important to apply the right metrics at the right stage in the product development cycle. As a software development company which builds engaging products, here are a few software metrics that we follow at Quovantis (with a why).

1. Team Velocity Points

Simply put, team velocity measures the average speed of your team towards achieving its goal during one Sprint. The fact that a typical Sprint goes on for about 2-4 weeks, the calculation of team velocity points proves to be a valid metric to gather the team’s efficiency.

If you want to calculate your team’s velocity, sum up the story points that were completed during that Sprint. To decide the team’s velocity, a three Sprint’s average is usually recommended.

Why? It’s an industry standard and it determines the pace at which the functionality is being developed. In simple terms, it tracks the velocity of a Scrum team over time. This metric helps in deciding whether the team can take up more work over time or if the team already overloaded and it needs to be reduced.

2. Sprint Burndown

Sprint Burndown

A Sprint burndown chart is the most effective tracking metric to visualize the health of the project. It helps in reviewing how much work is pending and if the team needs to speed up or slow down. You can also predict the expected completion date of the Sprint. A deviation from the expected burndown will send a red flag to the Scrum Master to take appropriate action.

For instance, if burndown goes up at any point during the Sprint, it reflects an addition to the existing scope. At this time, it’s important for a team to achieve the ‘team’s goal’ first before fetching new items from the backlog.

Why? The Burndown chart indicates the progress of work within a Sprint. It shows whether the amount of work a team is accomplishing every day will lead to a successful Sprint completion or not.

3. Release Burnup

Release Burnup

Product owners need to evaluate what should be out in the market first based on their discussions with other stakeholders. A Release Burnup helps POs to continuously prioritize the product backlog based on how the work is progressing.

If the release date is fixed and there have been a few additions to the initial scope, this is an important metric to align scope with the actual release date by either removing low priority backlog items or attempting to increase velocity by taking suitable measures.

Why? The Release Burnup chart indicates whether the Sprints are progressing towards successful completing the project. Also, the Release Burnup gives us a projected date of completion of the project.

4. Estimated Cost vs Actual Cost at Completion

Often there are gaps between the estimated cost projection during the start of the project and the actual cost at the completion of the project. This metric gives a measurement of what deviations could have led to this difference in the cost.

Although the project cost is almost always higher than expected, this metric helps you understand the possible causes of cost overrun - be it some design error or some changes in the scope of product development.

Why? Helps us understand what cost we had estimated and what cost was incurred. This helps us in improving our planning.

5. Number of Major Bugs per Sprint

The number is an indicator of the overall quality of the product. When you are working on an Agile project, it becomes important to put a budget, i.e. count, on the number of major defects open in a project at any point in time.

How can we stay within the budget? Reduce the count of defects reported.

How can we reduce the number of defects? Do Not Report!

Yes, I’m kidding.

Here is a better solution - during the Sprint planning session, look-ahead and clearly define acceptance criteria before jumping on a Sprint backlog item.

The priority of resolving any major bug is over and above implementing any new feature. Because, if you can’t resolve what you did wrong, you cannot pick a new feature.

At the same time, keep a close watch on the number of bugs reported after production release. If you have not been proactive in refactoring and improving the quality of your code, chances are you will receive nasty numbers in this metric. This will help you to identify gaps in testing and take corrective measures

Why? If you see it in conjunction with the overall points, the ratio over time can tell whether the quality is improving or not. More important than picking a new story point, I'd say.

Which software metrics do you follow as part of your software development process?

New roadmaps, more flexible boards, and dozens of new integrations. And that's just the beginning.
