– How can we measure software code quality?

Weighted Micro Function Points:

Weighted Micro Function Points (WMFP) is a modern software sizing algorithm that is a successor to solid ancestor scientific methods. It produces more accurate results compared to traditional software sizing methodologies. It requires less configuration as most of the estimation is based on automatic measurements of an existing source code.

Reliability:

Reliability measures the probability that a system will run without failure over a specific period of operation. It relates to the number of defects and availability of the software.

Number of defects can be measured by running a static analysis tool. Software availability can be measured using the mean time between failures (MTBF). Low defect counts are especially important for developing a reliable codebase.

Testability:

Testability measures how well the software supports testing efforts. It relies on how well you can control, observe, isolate, and automate testing, among other factors.

Testability can be measured based on how many test cases you need to find potential faults in the system. Size and complexity of the software can impact testability. So, applying methods at the code level — such as cyclomatic complexity — can help you improve the testability of the component.

Reusability:

Reusability measures whether existing assets — such as code — can be used again. Assets are more easily reused if they have characteristics such as modularity or loose coupling.

Reusability can be measured by the number of interdependencies. Running a static analyzer can help you identify these interdependencies.

Count of open reported defects in a given product.

Defect density. Take the number of defects found per the number of source lines of code in the product. Lower is better. However, this metric does ignore defects that haven’t been recorded.

– What metrics could we measure?

– Qualitative metrics are subjective measurements that aim to better define what good means.

There is a number of metrics available based on which software quality is measured. But among them, there are few most useful metrics which are most essential in software quality measurement. They are

Reliability – Reliability metrics express the reliability of software in different conditions. The software is able to provide exact service at the right time or not is checked. Reliability can be checked using Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR).

Performance – Performance metrics are used to measure the performance of the software. Each software has been developed for some specific purposes. Performance metrics measure the performance of the software by determining whether the software is fulfilling the user requirements or not, by analyzing how much time and resource it is utilizing for providing the service.

Usability – Usability metrics check whether the program is user-friendly or not. Each software is used by the end-user. So it is important to measure that the end-user is happy or not by using this software.

Correctness – Correctness is one of the important software quality metrics as these checks whether the system or software is working correctly without any error by satisfying the user. Correctness gives the degree of service each function provides as per developed.

– Give recommendations to improve code quality as feedback from quality team after code inspection.

Analyze Code — Before Code Reviews:

Quality should be a priority from the very start of development. There isn’t always the luxury of time as development progresses. That’s why it’s important to analyze code before code reviews begin. And it’s best to analyze code as soon as it’s written.

Follow Code Review Best Practices:

Manual code reviews are still important for verifying the intent of the code. When code reviews are done well, they improve overall software quality.

Refactor Legacy Code (When Necessary):

One way to improve the quality of an existing codebase is through refactoring. Refactoring legacy code can help you clean up your codebase and lower its complexity.

– How can we measure the software processing in term of time?

By breaking the measurement periods into smaller time frames, the software development team can check the software metrics — and the trend line — to determine how well they are progressing.

Yes, that is an interruption, but giving software development teams more time to analyze their progress and change tactics when something is not working is very productive. The shorter periods of measurement offer more data points that can be useful in reaching goals, not just software metric targets.

– How can the results of these measurement relate to managerial skills?

– Because managers have some qualities through which they can affect many things, not just measurement, and through this characteristics that managers have, you can notice these effects on measurement in a very short period, and from these characteristics we have our technical ability through which managers can They use a set of techniques to achieve the desired goals in a short time, and this benefits the measurement and does not include the operation of programs only, but also includes the skills necessary to increase sales and his ability to create new things to increase production, and this affects the measurement in the organization and the characteristics of managers that also make it different from Others are his ability to deal with many people and understand what they need in a simple way and his ability to translate their problems into solutions they want.

– Using the classic cost quality model, mention two examples of typical costs within each category?

– Classical cost quality control includes two example important for cost.

Costs of Software Quality

1- Costs of control 2- Costs of failure of control

Costs of control :

Prevention costs include investments in quality infrastructure and quality activities that are not directed to a specific project or system, being general to the organization.

Appraisal costs include the costs of activities performed for a specific project or software system for the purpose of detecting software errors. They are devoted to detection of software errors.

Costs of failure of control :

Internal failure costs include costs of correcting errors that have been detected by design reviews, software tests and acceptance tests (carried out by the customer) and completed before the software is installed at customer sites.

External failure costs include all costs of correcting failures detected by customers or the maintenance team after the software system has been installed.
