There are several important people metrics in software engineering that can help measure the performance and effectiveness of a software development team. These metrics include:

  1. Productivity: This metric measures the amount of work that a team is able to complete within a given time period. It can be measured by the number of lines of code written, the number of bugs fixed, or the number of features implemented.
  2. Quality: This metric measures the overall quality of the software being developed. It can be measured by the number of defects or bugs found, the number of customer complaints, or the number of support requests.
  3. Velocity: This metric measures the speed at which a team is able to deliver new features or updates. It can be measured by the number of iterations completed, the number of deployments made, or the time taken to complete a sprint.
  4. Retention: This metric measures the rate at which team members stay with the company. It can be measured by the number of team members who leave the company or the length of time team members stay with the company.
  5. Employee satisfaction: This metric measures how satisfied employees are with their work, the company and the environment. It can be measured through employee surveys, interviews, or questionnaires.
  6. Diversity and Inclusion: This metric measures the diversity within the team and the company, it helps in understanding the representation of different groups of people in the company and their inclusion in the decision making process.
  7. Team cohesion: This metric measures how well team members work together and how well they are able to collaborate and communicate. It can be measured through team surveys, interviews, or observation.

It’s important to note that, these metrics are not mutually exclusive, and a combination of them can be used to get a comprehensive view of the team’s performance. Additionally, these metrics should be tracked over time to identify trends and patterns, which can help identify areas for improvement.

According to the view point of the software developers, the various metrices are very important to all the software managers. Following are the various software developer metrices are :

  1. Lead
  2. Churn
  3. Impact
  4. Active Days
  5. Efficiency

The derivation of these five metrices are used for the version control data. The Metadata which is obtained from these modern code repositories helps to provide real-time insights into engineering work patterns and  also to the health of your team.

1. Lead Time :
Lead Time is the time between the beginning of the development of the project until it is delivered to the customer or completed. The history of any lead time will surely help the developers when an item will be ready with a high degree of accuracy. The data of lead time is also useful in case if your development team doesn’t routinely provide estimates, because the predictions for the delivery of project to customer also based on the lead times of similar projects.

2. Code Churn :
Code Churn is the percentage of a developer’s own code representing an edit to their own recent work. Basically it is the lines of code that need to be modified, added and deleted during the short period of time such as few weeks. The main objective of this is to help the software managers and the other project stakeholders to control the development process of the project, specially considering its quality.

3. Impact :
Impact can be defined as; it is the effect that produce due to the change of code within a project, and also it is a way to consider the cognitive load that is on the developer who implemented change to code. The more difficult change set to project will produce the high impact score.

 The impact of a change set depends on a variety of factors as follows :

  • The amount of code in the changes;
  • The severity of those changes;
  • The number of files that the changes affected.


4. Active Days :
The day whenever an engineer contribute code to project referred as an Active Day. Tasks that the engineer do in an active day includes such as writing and reviewing code. Engineers are uniquely skilled at building and solving difficult conceptual problems, so contributing code is one of the most important things that an engineer can do. Non-engineering tasks such as planning, meeting and chasing down specifications are inevitable.

5. Efficiency :
The efficiency is the measure of percentage of an engineer’s contributed code that’s productive, which generally involves balancing coding output against the code’s longevity. Efficiency is independent of the amount of code written. The higher the efficiency rate, the longer that code is providing business value.

Advantages Of People Metrices :

  • It assist people to speak the language of the executive teams.
  • Public Sector agencies are at various stages in their use of people metrics and collection of data.
  • Departments and agencies also have different tools and people information systems for collecting and integrating data.
  • Improved team performance: By tracking and analyzing people metrics, managers and team leaders can identify areas for improvement and take steps to increase team productivity, quality, and velocity.
  • Increased accountability: People metrics can help hold individuals and teams accountable for their performance.
  • Better decision making: People metrics can provide managers and team leaders with valuable data that can be used to make informed decisions about team structure, resource allocation, and other important issues.
  • Improved employee satisfaction: By tracking employee satisfaction metrics, managers can identify areas where employees are unhappy and take steps to improve the work environment and culture.
  • Increased diversity and inclusion: By tracking metrics related to diversity and inclusion, managers can identify areas where the team or the company is lacking in representation and take steps to improve it.
  • Better team cohesion: By tracking team cohesion metrics, managers can identify areas where team members are not working well together and take steps to improve communication and collaboration.
  • Better retention: By tracking retention metrics, managers can identify the reasons why employees are leaving and take steps to improve employee satisfaction and retention.

Overall, people metrics can provide valuable insights into the performance and well-being of a software development team. By tracking and analyzing these metrics, managers can make data-driven decisions that can improve team performance and employee satisfaction, and also increase diversity and inclusion in the organization.
