Every conversation I have with CTOs, Engineering Managers, and Tech Leaders eventually gets to the “Which Metrics Should We Measure?” discussion. Too often, software engineering team leaders are worried that measuring metrics could be perceived by their team as an unnecessary, intrusive complexity that will erode their culture and wellbeing. Naturally, managers are afraid of the possible fear and resistance their team members might feel at the introduction of a new measurement system. As an answer to this concern, I always explain that there are a few incredibly useful, easy to collect metrics that will help the whole team understand where they should focus next. understanding that those metrics are there to help the team focus on the next big issue for improvement. That’s the key: First: What are Agile Metrics? Agile Metrics is an umbrella term for metrics that deal with the underlying agile methodology your software team is probably already using, be it Scrum, Kanban, or any other. As such, they can be derived from a visible board with each column describing one state of work (Backlog, Committed, In Development, Approval, and Released are my starting recommendation). You can also derive these metrics from backlog management software like Jira, Trello, Clubhouse, and others. Agile Coaches, Product Managers, CTOs, CPOs, Engineering Managers Used by: Here are the top 10 software engineering team metrics I recommend, and have been using for the past 12 years. 1. User Story Lead Time Measures the time between the start and finish of a User Story. I recommend defining the start as when you move the User Story to the “In Development” column, and defining finish as the column “Released”. It’s important to use a backlog management software that helps you with that, usually by having a starting_at and finished_at fields in their API and UI. Jira and Clubhouse are the best examples. Although you can put each individual lead time on a chart, I prefer to work with percentiles (p50 and p90 give great insight) and plot them over time, on a weekly basis. 2. User Story Throughput Aggregates all User Stories that were released to the customers in a weekly or monthly base. I also like to group it by the type of User Story (usually “bug”, “feature” or “chore”) and visualize that over a period of time. 3. CFD (Cumulative Flow Diagram) I consider a CFD as a better version of a Burn-up graph. In a CFD, you can quickly analyze how much work has been done, how much work is in progress, and how much work still needs to be done to reach a predefined milestone. To build a CFD, you plot the sum of the User Stories in each column, over a time series (weekly works best, in my opinion). Engineering Metrics If we think that Agile Metrics has more to do with the agile process and user stories, Engineering Metrics tell us another story: how work is being done internally to meet the requirements of the agile process. Or put in another way, how can we explain the Agile Metrics? That’s where Engineering Managers and CTOs fall short. Agile Metrics tell us part of the story, but we also need to have a grasp on the Software Engineering process. How is quality evolving over time? How does the deployment process explain what we’re seeing at the CFD level? How good is our onboarding process for new hires? Some of the best CTOs I’ve met have some of these Engineering Metrics on-hand and can explain the action items their team is focusing on a C-Level board meeting. Tech Leaders, Engineering Managers, CTOs Used by: 4. Pull Requests Lead Time How long does it take for a Pull Request to be closed or merged? As with the User Story Lead Time, it’s best to aggregate using percentiles and group by weeks or months. Especially useful for raising questions and start investigations before it’s too late. I also prefer to merge Pull Requests Lead Time and Throughput in a single chart like this: 5. Pull Requests Throughput Takes into account how many Pull Requests were merged on a weekly basis. Good to see rapid changes in the activity level for a team. 6. Time from Commit to Deploy Even though you can have a high throughput, sometimes what’s being delivered in a deploy is “old.” Maybe you don’t have any automated deployment practice in place. Maybe people take a long time before opening a Pull Request. This is a great way to measure your overall software development process. 7. Frequency of Deploys The code not in production is just inventory getting stale. Shipping code to production should be everyone’s responsibility and having a metric showing over time how many deploys a day you’re doing can be critical to that. 8. Frequency of Rollbacks Monitoring how many rollbacks you’re dealing with relates significantly to the quality of the whole software engineering process. 9. Code to Test Ratio Another way to measure quality, although this one is tricky. This metrics is prone to be manipulated very easily by developers. Even though it’s advantageous to see how things are changing over time as the team scales up and brings new people on board. 10. Code Quality Issues Every codebase has its share of technical debt, not-so-clean code, gimmicks, and rushed work. It’s not important to have zero code quality issues, but again, it’s crucial to understand how this number works over time as a team scales up, and there are more code and repositories to maintain. You can uncover problematic areas of code that could explain rollbacks, long lead times, and bottlenecks. Conclusion These metrics have helped me on more than a dozen occasions, specifically in meeting my personal goal in every team I work with: continuous improvement. Do you think these metrics can help your team with continuous improvement? Please let me know in the comments.
