1. Team productivity and efficiency metrics


These metrics help you discover whether the forecasted delivery of value tousers is taking place efficiently and predictably. These metrics delvespecifically into the productivity and efficiency of the team’s developmentprocess.Here is a list of metrics to track the speed of development and delivery ofvalue in the application development process. * Lead time: This is the time elapsed between the identification of a requirement and its fulfillment. It is the duration between the formulation of a user story and its subsequent release. * Cycle time: This is the time from when the actual work is started by the agile team until the line item goes from in-progress to completed. Each team has its own definition of complete, so the definition of done should be determined right at the beginning. Since the acceptance criteria vary from person to person, defining them at the start is essential to avoid confusion. * Sprint velocity: Velocity is the amount of work completed by the agile team in a given period of time. Sprint velocity is basically the rate at which the conditions mentioned in the software requirements specifications get converted into lines of tested code, or the number of story points covered by the team on every sprint. * Flow efficiency: Lead time includes both working time and wait time. The ratio of the actual work time measured against the total wait time gives us the flow efficiency. * Stories committed vs. completed: The completion against commitment metric (CaC) is the percentage of user stories completed in the sprint against the total committed during the planning meetings. * Sprint burndown: Also known as the burndown chart, this is a graphical representation of estimated tasks planned and the actual tasks completed. * Cumulative flow diagram: This is a visual representation of the stages all the different tasks are in at any given period of time. The vertical axis denotes the various story points, while the horizontal axis is the time. * Control chart: This denotes the cycle time of issues to go from in-progress to the done stage. Agile teams with consistently shorter cycle times have greater throughput, and the control chart helps visualize any changes on an immediate basis.

2. Development quality metrics


Quality metrics deal with the quality of the application developed, namely thenumber of defects discovered either during production or as a part of userfeedback.In agile, the QA mindset is embedded into the development process. The entireteam takes ownership of the quality of the application being developed andorganic improvement in the quality of software being developed.Here are a few quality-focused agile metrics you can choose from to ascertainthe quality of the application being developed. * Escaped defects: This is the number of bugs the agile team encounters after a build, after a sprint completes, or when the release enters into production. * Defect density: This is the number of defects detected in the software module within a particular duration, divided by the size of the software being developed. * Code churn: Churn measures the lines of code added, removed, or altered. By visualization of the fluctuations in the churn rate, the quality of the software being developed can be predicted. Agile teams should aim at churn close to zero as releases approach. * Defects deferred: Bugs entering the deferred state implies that the bugs discovered are scheduled to be fixed in the next release. * Automated test coverage: Test coverage is the amount of testing performed on a product. Automated test coverage calculates the degree to which the application code is covered by test cases and what portion of it takes place in an automated manner. * Failed deployments:This is the total number of deployments released into the testing and production environments that fail. It helps in determining the reliability of these environments and whether your agile teams are developing working software.

While most agile software development metrics are aimed at assessing softwarequality and team productivity at different stages and from differentperspectives, monitoring the well-being of your team is as crucial.

Measuring Software Quality in Agile


Today, customer demand prompts companies to deliver and update their softwareproducts faster. This means frequent changes to source code that can lead toboth small and big defects. Although agile helps teams streamline the softwaredevelopment process, it is inseparable from security. While you will usemetrics like Code Coverage, it is also important to assess code quality. As aresult, conducting a comprehensive code analysis becomes crucial alongsideusing agile metrics.There are two types of code analysis and one more comprehensive approach thatcan help teams streamline their quality assurance across projects. Let’sexplore them below.

Top Useful Agile Metrics: Measure Quality, Productivity & Performance


Agile metrics are a crucial part of an agile software development process.They help software teams monitor productivity across workflow stages, accesssoftware quality, as well as introduce more clarity to the developmentprocess. Metrics in agile software development can also help scrum and kanbanmasters keep track of their teams’ well-being.For our list, we have chose the metrics that can be useful for the majority ofagile teams. There four different metrics groups in our selection — softwarequality, team productivity, general project metrics, and teamperformance/well-being agile metrics.See the list below.

Agile Productivity Metrics


The following selection of agile development metrics helps to assess yourteam’s productivity in completing stories, tasks, and bigger bodies of work.The many useful agile productivity metrics will also help you predict theproductivity of your team in forthcoming sprints, prevent bottlenecks, andtackle unexpected changes to the scope.Lead TimeThis metric will let you monitor a story from the point when it enters thebacklog until the sprint’s end or release stage. The lower the lead time, themore effective your development process is. Lead time is one of those agilemetrics that allows for gaining an overarching perspective on the productivityof your development efforts.Cycle Time (Control Chart)Part of the lead time metric, cycle time will help you assess the averagespeed with which your team fulfills a task. If your team has short cycletimes, it means they are highly effective. Concurrently, when your team’scycle team is consistent, you can better predict how they will work in thefuture. This metric will also help you to quickly pinpoint the emergingbottlenecks in your agile software development process.Sprint BurndownBefore starting a sprint, teams forecasts how much work they can finish in thecourse of it. The sprint burndown report (visualised as a chart) tracks thecompletion of story points in a given sprint. This helps the team to ensurethey will complete the sprint scope within the planned time frame.Sprint burndown chart example, Scrum InstituteSprint burndown chart example, Scrum InstituteSprint burndown is one of the most effective agile productivity metrics for afew more reasons. First, it allows you to track the progress of a sprintclosely and in real time. Second, the metric shows how agile your team reallyis.Epic & Release BurndownThese metrics (also visualised as charts) allow teams to track bigger bodiesof work than sprint burndown can cover. One of the major benefits of epic andrelease burndown is that they help to manage “scope creep” — the adding of newrequirements after the project was already defined.Thus, these agile metrics will help ensure your team will not lose inproductivity, for example, after the product owner on your project tasks yourteam to add a new, massive feature.VelocityVelocity is one of the most essential metrics in agile software development,allowing you to measure the average quantity of completed story points overseveral past sprints. Consequently, you can use the metric to foresee howeffective your team will be in forthcoming sprints, making it a ratherpowerful planning means.Velocity chart example, AtlassianVelocity chart example, AtlassianThe benefits of velocity also include: * Easy to measure * Shows a clear result right away * Lowering velocity may signal about emergings inefficiencies in a sprintAs many factors can influence productivity, it is crucial to follow how yourteam’s velocity changes over time.

Health Metrics for Agile Teams/Agile Performance Metrics


While most agile software development metrics are aimed at assessing softwarequality and team productivity at different stages and from differentperspectives, monitoring the well-being of your team is as crucial.HappinessThere is no single, tried-and-true way to measure happiness in a softwaredevelopment team. Still, a common solution is to ask every team member to ratecurrent happiness on a scale from 1 to 5. According to organizationalpsychologist Christiaan Verwijs, this can be followed by several questions,for example: * How happy are you with your company? * What feels best right now? (open question) * What feels worst right now? (open question) * What would increase your happiness? (open question)Team MoraleVerwijs proposes another way to access the well-being of members of agilesoftware development teams — measure team morale instead of happiness. Heargues that the happiness metric is unreliable due to its subjectivity, andthat measuring it entails many nuances that does not help to solve the problemneither for the individual, nor their team. Instead, Verwijs says thatmeasuring team morale is a more subtle, team and task oriented way biased orsusceptible to changes in mood.The psychologist suggests to measure team morale by asking team members torate the following statements on the scale from 1 to 5 (or from 1 to 7, as itmore nuanced): * I feel fit and strong in my team * I am proud of the work that I do for my team * I am enthusiastic about the work that I do for my team * I find the work that I do for my team of meaning and purposeThe questions are more specific, allowing you to better access the well-beingof your team members.Still, approaching and accessing such aspects is a nuanced subject, and it isup to the scrum or kanban master to choose the most fitting of these agileperformance metrics, or approach the team members’ well-being in their ownindividual way altogether.Should you use these metrics for agile teams at all is another question youmight ask, especially if you can have face-to-face discussions whenever youneed to talk through your team members’ issues. If you have doubts about agileteam performance metrics, you can start small by measuring happiness monthly,and see how everything goes.

However, in any agile softwaredevelopment, it follows iteration which ensures continuous delivery.Let’s look at some of the popular agile methodologies and their overview:Brainstormed by 17 software programming professionals in February of 2001, theagile manifesto was developed for effectively build software. The manifesto isnothing but the agreed thoughts of the leaders which focuses on four values: * Individuals and interactions over processes and tools * Working software over comprehensive documentation * Customer collaboration over contract negotiation * Responding to change over following a planAlong with that agile software development which is supposed to implementagile manifesto must follow twelve manifesto principles and these are: 1. Customer satisfaction through early and continuous software delivery 2. Accommodating changing requirements throughout the development process 3. Frequent delivery of working software components 4. Collaboration between the stakeholders and developers throughout the project 5. Motivate, support and trust the people involved in the project 6. Enable face-to-face interactions 7. Considering working software as the primary measure of progress 8. Agile processes for supporting a consistent development pace 9. Attention towards technical design and detail to enhance the agility 10. Simplicity 11. Self-organizing and motivated teams encourage great requirements, architectures, and designs 12. Focus on how to become more effective on a regular basis.> Also Read: How to build a career in Agile?Extreme Programming follows an agile software development model thatemphasizes on a high level of involvement between the development team and thecustomer. The customer makes the user stories and prioritizes them for thedevelopment. Then the development team follows the continuous iterative modelto deliver the user stories. Each iteration involves planning, programming,testing, and continuous collaboration. Furthermore, each iteration cycletypically takes 1 to 3 weeks.This is an aggressive agile development model that ensures fast delivery.However, it is among highly disciplined agile methodologies which needextremely skilled project associates.This is the mostly used agile methodologies in agile software development. Inthis method, the product owner prioritizes the iterative work based on system-wide functionality which is known as “product backlog.” In SCRUM, theiteration is known as a sprint, and it generally lasts up to 30 days.In this agile development model, the scope creep is well controlled becauseonce the sprint is committed and further development functionality is notentertained in that sprint. After every sprint the product backlog is analyzedand, they are reprioritized for the next cycle.> Try Now: Professional Scrum Master PSM I Free Exam Simulator
