Development time

What is development time?

Development time refers to the period during the software development process specifically allocated to the actual coding or programming of a feature. This metric begins from the moment a developer starts writing code for a feature and concludes when the feature is deemed complete and ready to be reviewed by others. To calculate development time, one records the start time when coding begins and the end time when the code is ready for review. The difference between these two timestamps represents the development time for that particular feature. This calculation helps teams understand how much time is directly spent on developing new functionalities.

Why is development time important?

Efficiency tracking. Measuring development time is crucial for tracking the efficiency of the development process. Organizations can analyze how long it takes for features to move from conception to readiness for review, identifying bottlenecks and opportunities for process improvements. This time metric helps in estimating future projects more accurately, ensuring that timelines are realistic and achievable.

Resource allocation. Understanding development time allows for better resource allocation. By knowing how long certain tasks take, managers can better distribute tasks among team members, balancing workloads effectively. This ensures that no single team member is overwhelmed while others are underutilized, promoting a more efficient and harmonious work environment.

Cost management. Development time is directly linked to project costs. Longer development times can lead to increased labor costs and delayed time to market, impacting overall project budgets. By monitoring and managing development times, companies can keep projects within budget and improve profitability.

What are the limitations of development time?

Does not account for quality. Development time focuses solely on the duration of coding until it reaches the review stage. It does not measure the quality of the code or the number of defects, which are also crucial for assessing the overall health of a software project. High-speed development could lead to poor quality if not balanced with effective quality assurance practices.

Varies widely between tasks. Development time can vary significantly based on the complexity of the task, the experience level of the developer, and the specific requirements of the feature. This variability can make it difficult to use development time as a standard measure of productivity or efficiency across different teams or projects.

Excludes other crucial phases. Development time does not cover the time spent on planning, designing, testing, and deploying the feature. These phases also consume significant time and resources and are critical to the success of the project. Focusing only on development time might give an incomplete picture of the overall effort and time invested in creating a feature.

Metrics related to development time

Cycle time. Cycle time tracks the total time from when work begins on a feature until it is completed, including both development and testing phases. It is closely related to development time, as reducing development time can directly impact the overall cycle time, helping teams to deliver features faster.

Review time. Review time measures how long it takes for the code to be reviewed and approved after development is completed. It is a direct follow-up to development time. A shorter development time can sometimes lead to rushed code, potentially increasing the review time if more issues need to be addressed during the review phase.

Build time. Build time refers to the duration it takes to compile the complete software from code into a runnable state. It is related to development time because any changes in the codebase (reflected in development time) could influence the duration of the build process. Efficient coding practices that reduce development time can also lead to optimizations in build time, enhancing overall productivity.
