7 Key Software Development Metrics to Ensure Quality

7 Key Software Development Metrics to Ensure Quality

For any software development company, it’s important to ensure that whatever product they are delivering has gone through a quality check. It’s a huge topic of discussion whether a company should measure the quality of the software projects and if yes, how? One can develop as many software applications assigned to the development company that they want; however, quantity does not define the competency of the company.

It’s the quality of the output that counts by the businesses. Any business would like to associate with that software development company which promises on quality delivery and in defined timelines. Failed timelines and inferior products are always discouraged by business and the development company often lose their customers due to the challenge.

If you too are concerned about the quality of the software application, we bring to you 7 metrics to ensure the quality of the final product. Let’s start with the metrics.

1. Agile Metrics

For agile processes, the quality is measured basically by lead time, cycle time, team velocity, and open/close rates. Agile metrics do not measure the overall quality of the software but helps in the planning and explicate decisions about process improvement.

  • Lead Time: Time is taken from idea to product development. It's the cycle time that calculates the time of completion of project aiding decision making throughout the process
  • Cycle time: Time taken to change the requirements in the software and deliver it to stakeholders and clients
  • Team Velocity: How many sprints are completed by the software team and in what time
  • Open/Close rates: How many issues are open and how much time does it take to close the issue

Since agile development is all about following an iterative process to complete the software development, to ensure quality above-mentioned factors are monitored to ensure the product delivered is quality checked at each level.

2. Security Metrics

This type of quality measurement is done to check how much responsive is the software application to security. This is important as security is one major factor that decides the success of the software application. Few specific metrics by software development companies to ensure the delivered output has surpassed the security concerns are:

  • Endpoint incidents: How many endpoints have been affected by an external threat like a virus over a period of time
  • Meantime to repair: How much time was taken to discover the security breach, think of a solution, deploy the solution and the working order.

Smaller endpoint incidents and meantime imply that developers are doing great in ensuring the security of the software applications.

3. Production Metrics

This type of metric allows software developers to measure the scope of assignments to be completed and measures the productivity of the software development teams. It basically estimates the total operational and functional speed. The units to measure the quality of the software are:

  • Active Days: Time spent by developer solely in coding the software
  • Tasks scope: The scope of the volume of codes delivered by the developer in a year
  • Productivity: The efficient volume of code developed by the coder
  • Code churn: how many codes were hanged, altered, deleted
  • In-between time: Time calculated between the failure and its recovery

 
4. Functional Metrics

Functional metric measures the quality of the software by calculating the work of software by checking the underlying code of the software. This test ensures that the functioning of the software performs as expected and does not throw any errors and bugs throughout the process. A custom software development company cannot launch a software unless they are sure of software functioning as per users’ expectations.
There are different kinds of functional testing metrics which measures the quality of the software application. Few to mention here are:

  • Sanity Tests
  • Smoke Tests
  • Integration Testing
  • Acceptance Testing
  • Regression Testing

 
5. Defect Density

Another software development metric to ensure quality is Defect density. Till now we have been going through quality metrics that would generally involve checking the quality of the software application. This metric alone measures the number of defects, bugs, errors, per lines of code (LoC) changed and altered in the codebase. Defect density is required to measure the quality of the software development to check for the high priority bugs that the team is struggling with during the test suites, test cases, and even product requirements. 

6. Code Coverage

Code coverage is also known as test coverage which is not exactly a quality metric but an indicator which assists the team in attaining the quality. It calculates the percentage of the lines of code that are executed while running the entire test suite. Code coverage helps in identifying the areas of breakdown in software development and the areas that are untested. This metric usually highlights the quality of the software application by identifying the underlying challenges and then the team can come up with ideas to overcome them.

7. Customer Satisfaction Metrics

Last but not least, customers can never be ignored or neglected when it comes to measuring the quality of software development. It’s the user who is going to use the final product and hence it is important to measure the quality of the application. The quality here is measured by the feedback, surveys and is calculated in percentage to analyze the overall quality.  

Conclusion

Software quality is something that cannot be ignored and thus to be taken seriously by every custom software development company. One cannot deliver a software application that is not quality checked and offer to users to use it. Software is generally the brand face of the business and no business would want to lose its customers at all. Software development quality metrics ensure that the quality of the software is maintained before it is delivered to users for final usage.

Dignity was their first step towards the Patient Care Division. With the growing awareness of adult diapers among the people and the need to address the problem of incontinence, Dignity was born. The idea was to challenge the existing social taboos predominantly present in India about the usage of adult diapers, and to extend a caring helpful hand towards people suffering from a leaky bladder.
