What are the rating criteria of a completed software development project
Delivering a high-quality, bug-free product should be one of the primary goals of every product team. It doesn’t matter if the product is designed by Da Vinci and solves world poverty, if it’s buggy and has low throughput and high latency, the user will never use it. To ensure that doesn’t happen, quality testing is inevitable. And here are a few of the popular rating criteria to test completed software development projects:
1. Code Quality
Code Quality is simply measuring the quality of the software’s code. Writing bug-free/error-free and semantically right code is crucial for delivering top-notch software with which users can fall in love.
Usually, this criterion is segregated into:
Quantitative Quality Criterion: Assesses how huge or complicated a software program is, the number of bugs/errors per 1000 lines of code, etc. and the lines and functions it has.
Qualitative Quality Criterion: Attributes such as readability, clarity, maintainability, effectiveness, documentation etc., are gauged.
2. Agile Criterion
In order to refine the development process, the Agile Criterion comes in handy. Lead and cycle time, velocity, etc. are a few factors you need to take into consideration.
The time developers take to propose ideas and innovations, build and complete the project, is tested. The shorter the time taken, the faster the product launch is, and the faster the customers will be attracted by your product and you’ll gain loyal customers.
This measures the time needed for the transformation of the idea into full-fledged software. And since most of the time it is an iterative process, this is a very broad rough calculation and can be also used to measure the efficiency of the teams.
The total time consumed by the developers to develop the product for each stage in sprints is measured.
3. Production Criterion
This criterion calculates the quantity of work already performed by developers, i.e. their performance speed, productivity etc. It can be measured by the following factors:
This is the time required by developers spent only on coding. Through this metric, you can easily find out the hidden expenses and timeframes usually left out of the calculations.
Mistakes and Improvement Time
While building software from scratch, programmers are prone to making mistakes. This metric enables scaling the time required by them to fix those errors and execute the improvement.
This is the stack of codes engineers are likely to deliver yearly. Through this metric, you can determine the number of developers you’ll need for your project.
This is the volume of codes programmers delivers efficiently.
This lets you identify how reliable your software is in various circumstances. You can also check whether the exact service, by your product, is delivered on time. With Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR), reliability can be measured.
This lets you assess how well your software reacts to security threats. The risk of a cyberattack is always high and this criterion measures how quickly your product can recognize risks and discard them. With the rise of concerns around user data and privacy among them, these criteria have been in the spotlight forever.
To check whether your software is feasible and customer-friendly and whether customers are delighted using it, Usability metrics come in handy.
To examine whether your software is functioning aptly and flawlessly, the Correctness criterion is implemented. It is based on the premise that if a user performs every required action correctly, the system should reciprocate similarly. If it doesn’t, the software has a problem which the user doesn’t deserve.
8. Size-oriented Criterion
A size-oriented criterion is implemented to measure the code’s size and find out the number of flaws, bugs and expenses for every 1000 lines, by using the KLOC quantifier (an acronym for Kilo (1000) Lines of Code). This is exactly what Quantitative Quality in Code Quality means as well.
9. Function-oriented Measurement
This metric helps measure the business functionality of your delivered project. User inputs, error reports, requests and messages, user inquiries, etc. are assessed via this method.
10. QA Metrics
Once your software development is completed, you need to test the quality of your project. This is done by QA metrics. Myriad metrics are implemented to test the software’s quality and these encompass executed and written test cases.
Usually, those criteria which are done by calculation are performed by a QA Lead and comes in handy to calculate the progress of your project. And the records of these calculated metrics help ameliorate your project’s life-cycle.
11. User Satisfaction
Delivering a product that meets the requirements of and satisfies the users is the prime objective of every business. When your users are happy, it becomes easier to sell your product. Thus, this criterion is useful to check whether your customers are happy or unhappy using your software. The data is collected through user polling (or feedback) and the results are gauged in terms of percentage.
