In software development productivity, where changes are almost inevitable, productivity plays an essential role in deciding upon the success rate of that particular project and the efficiency level in the specific field of the software development team. In the ever-growing technological world and an ever-changing market, development teams have to assess the efficiency of software development productivity to make improvements when needed.
Performance indicators are thus of utmost importance when it comes to this issue, in the sense that they afford different angles of information concerning the development process. Thus, these measures help teams to define weak links, adjust and improve the processes, and make accurate decisions based on effective results. In this qualitative systematic review, the focus will be made on the major factors affecting software development productivity that the analyzed indicators can support. Code quality and the frequency of code deployments to collaboration between developers and lead time are some of the metrics that, if well understood and applied, can improve efficiency in software development productivity.
1. Cycle Time
The cycle time indicates the time taken to complete work on a task from the time work begins until its completion. This metric enables the teams to have an appreciation of how fast they are going to deliver the features or fixes. The shorter cycle time means that the software development productivity workflow process was more efficient as compared to before. As for cycle time, teams need to make efforts to decrease the time spent on any activity that is not the core of the process, like waiting for code review or testing.
2. Lead Time
Lead time is the total time taken to address a given request right from the time it was made until it was delivered. This is the total amount of time required to complete the work involved in accomplishing the task, and this time includes time spent on the actual work as well as time spent waiting for something to happen. Lead time tracking allows teams to realize when their processes need to be brought to order to deliver what is required on time. Reduction of lead time usually entails the right adjustments on various developmental processes from the time the request is made to the time the actual product is delivered.
3. Deployment Frequency
The frequency of deployments defines how often the particular team sends new code to the production environment. Expressions such as high frequency show how fast a team can develop updates and new features of the product. This metric is essential, especially in the engineering settings that use the agile and DevOps approaches. To increase the frequency of deployment, much effort should be taken on how to automate the deployment procedures and also to ensure that their code is always ready for deployment.
4. Change Failure Rate
The degree of change failure rate is the extent to which some of the changes deployed will fail to work as expected, for instance, a bug or an outage. This metric gives teams insight into the stability of their releases and how stable those releases are likely to be. It means that there should be more testing and Quality Assurance before the application is deployed into production environment if the change failure rate is high. To help avoid a high change failure rate, the teams can adopt practices such as testing, integrating, and reviewing the code frequently.
5. Mean Time to Recovery (MTTR)
MTTR gives an average time taken to be back to a production level after a failure has occurred. This metric is essential to how a team will be able to respond to problems and find solutions to challenges promptly. A decrease in MTTR means the work of a more tolerant and reactive team has been done. Furthermore, the management of the MTTR mainly requires having accurate monitoring and alerting methods implemented together with proper management of the incidents.
6. Code Churn
Code churn means code changes, that is to say, how many lines of code are added, modified, or deleted in a specific time frame. Large values probably signify instability in relative code base retrieval, as many changes are likely to introduce errors in addition to other shortcomings. Measuring code churn allows a team to find out which parts of the code can be considered to be rewritten frequently and thus might need refactoring or more code test coverage. Looking at the prevention of code churn, it is therefore very important to enhance the quality and stability of the codes used by designing and testing.
7. Code Review Metrics
The measurable factors of code review are the number of code reviews conducted, the time it takes to do code review, and the number of comments or problems found during the code review. Some of these metrics are useful in identifying the efficiency of a group’s code review procedure. Possibly thorough code reviews can detect all the bugs, increase the quality of the code, and help the team to share their knowledge. It appears that to avoid deterioration of code review metrics, teams can set specific requirements and remind the participants when the feedback has to be provided.
8. Defect Density
Defect density defines the number of defects within a given product of the software development productivity and the size, generally in terms of line of code. This metric is beneficial in analyzing the work accomplished by teams to increase the quality of the code that they produce. It also shows that a product with a smaller number of defects will have better quality code. To resolve this issue, teams can introduce proper testing standards that can be periodically checked and increase the level of developers’ training and code reviews.
9. Customer Satisfaction
Satisfaction of customers is one of the important measures for the success of a software product. It can be assessed using questionnaires, feedback, and customer reviews. That is why customer satisfaction reveals that the developed or purchased software corresponds to the customers’ requirements. This means that teams can concentrate on providing high-quality features, solving every bug that a user may find on the application, and ensuring that the users are well attended to.
10. Team Velocity
The team velocity is that which defines how much the team can accomplish within the specified duration, which is normally a sprint in the usage of agile frameworks. This metric is greatly beneficial to enhance long-term planning and, therefore, allows teams to gain better estimations of the work in the future. It is therefore clear that employer participation implies an efficient operation of the team regarding velocity, which can either be stabilizing or increasing at some point. To increase velocity, teams can thus concentrate on four areas: increasing the removal of impediments; increasing cooperation; and increasing the accuracy of useful estimating.
11. Work in Progress (WIP)
WIP quantifies the number of tasks in progress and also gives us a tool to track the number of tasks in each state. WIP limits are effective in managing the team’s attention and preventing multitasking, which is likely to cause an efficiency decrease. WIP tends to increase if there are bottlenecks or other systemic issues along the value stream. To control WIP, it is possible to use Kanban boards and adjust WIP constraints for various phases of the team’s work.
12. Escaped Defects
The escaped defects are those quantities of defects that are found in the total production after a particular software has been released into the market. This metric assists the teams in finding out how efficient the testing and quality assurance are in the team. If the number of escaped defects is high, this means that more testing is required before a product is released into the market. The best ways of managing escaped defects include the following: using automated tests; completing comprehensive code reviews; and testing for regression at regular intervals.
13. Technical Debt
Technical debt is defined as the cost of important additional effort required to correct problems that are created by shortcuts and suboptimal design decisions taken during the technical implementation process. This metric enables teams to measure the long-term value of one developmental practice against another. High technical debt may hamper the future development process and also cost a lot in the maintenance process. For dealing with this type of debt, the teams are encouraged to refactor, increase generally the quality of code, and plan time for paying this type of debt.
14. Build a Success Rate
Build success rate aims at measuring the efficiencies of successful builds in the continuous integration processes. This metric benefits the teams to quantify the stability within their code base and also the efficiency of the build process. A good build success rate proves that the code is right and also the build process is effective. The way to enhance the possibility of build success is the usage of automated testing, correct handling of dependencies, as well as the absence of extra or unnecessary code.
15. Time to Market
Time to market is the period taken to have an idea a new feature or a product to be in the market. This metric gives a mean to an end by assisting some teams to relate their capacity to meet market needs and generate values for customers within the shortest duration.
This means that the shorter the time it took to develop the product, the better it is in terms of efficiency The total time taken for development can be measured in the number of months it took for the products to be produced and marketed. Some common choices containing the time-to-market pressure include teaming, development process optimization, and the tendency to deliver minimum viable products within the shortest time possible.
16. Employee Satisfaction
Work satisfaction is also an essential measure of the employees’ condition and the incentive of the software development productivity team. This metric can be measured through self-administered questionnaires, feedback forms, and during one-on-one interviews with employees. A low turnover implies that the company is creating a good environment for its employees since a high satisfaction level results in high performance and thus higher retention rates. To make the employees happier, the teams can turn their attention to software development productivity, relationships, and balance between work and the rest of their lives.
17. Feature Usage
Feature usage deals with the determination of how frequently various features of the software are accessed by the users. This measurement assists groups in determining which function is highly demanded by consumers and which one should be fine-tuned or eradicated. A large number of features used signifies that user requirements are being met by the software development productivity. To increase the use of features, feedback can be collected from the users, usability tests can be conducted, and maximum perceived value for its customers can be selected.
18. Cost of Delay
COAM represents the cost of delay, which regulates the financial consequences of a delay in the delivery of a feature or a product. This metric assists in segmenting tasks as per a probable revenue or cost saving possible if features are delivered early. Hodgson and Johnson (1992) proposed that the higher the cost of delay, the more important it is to deliver the project on time. From the above understanding of the cost of delay, teams can utilize methods such as Weighted Shortest Job First (WSJF) to undertake work that has a bigger economic effect.
19. Release Burndown
Release burndown is used to track the effort made on a release, the amount of effort that still needs to be done, and the efforts that have been accomplished within a specified period. This metric assists the team to monitor their progress and modify their overall strategy to enable them to achieve the set release dates. It therefore shows how the team progresses in ideally a smooth curve, while a wavy curve may indicate problems or setbacks. There are three recommended improvements: firstly, work should be finely divided to make it easier to plan and track progress, secondly, work pace should be consistent, and thirdly, problems should be resolved as soon as they are identified.
20. Sprint Burndown
Sprint burndown tracks the amount of effort that has happened in the course of a sprint and the amount of effort that needs to be done. Sprint velocity is used as a measure so that it can be seen whether the different teams are on track or not concerning achieving the goals set for a given sprint. The sprint burndown chart that has a smooth wave shows that the team is right on course, while the jagged one may be a result of some problems or setbacks.
To enhance sprint burndown, several approaches can be adopted, the first one being the practice of detailed sprint planning, second, the maintenance of a constant work rate, and finally, tackling impediments as they occur.
