Process Evolution Metrics
As the name implies, these metrics keep track of how a process evolves over time, such as the number of iterations it goes through. They act as a kind of time-lapse of your experience developing software, allowing you to see how your method has changed over time.
#2. Product Metrics
These are an essential tool that aids firms and developers in ensuring the caliber of their software output. Product metrics are important indicators that track different facets of a software product, such as its size and design as well as its functionality, quality, and complexity. These indicators help developers understand and improve the quality of their software development, which leads to better products.
During every stage of the software development process, product metrics are relevant. They support requirements management, design, implementation, or maintenance of current systems. They just pay attention to software features.
There are two categories of product metrics:
- Dynamic Metrics
- Static Metrics
These are gathered by observing program execution while it is running. You can evaluate a software product’s effectiveness and dependability with the aid of dynamic metrics. For instance, you can calculate the starting time for the system and assess the execution time needed for particular operations, which is directly related to the effectiveness and dependability of the software.
Measurements taken from system representations like designs, codes, or documentation can be used to gather these metrics. Understanding and maintaining the complexity of a software system are the key goals of static metrics. Numerous static metrics have been put forth to show a correlation between complexity, understandability, and maintainability, despite the fact that they only directly relate to quality criteria. The length of the program or component and the complexity of the controls are two of the most effective predictors of these characteristics.
For software engineers and businesses to assure the quality of their products, product metrics are crucial tools. You may improve your software development process and make educated judgments by comprehending and applying these metrics.
#3. Project Metrics
These tiny pearls are essential for successfully organizing and carrying out undertakings. One type of statistic used in software testing is the project metric. They are crucial resources that aid in our comprehension of a project’s qualities and development. The amount of software developers, employment patterns, costs, schedules, and productivity are just a few of the topics they examine. Project managers can use data from completed projects to estimate the time, cost, and other aspects of new initiatives. Managers can reduce development costs, efforts, risks, and time while raising the project’s quality by routinely tracking and comparing these indicators.
Project metrics are essential for helping project managers assess ongoing initiatives and monitor potential hazards. They are a useful tool for identifying problem areas, optimizing procedures, and determining the project team’s ability to consistently produce high-quality work. It’s important to note that project metrics are frequently used for tactical goals.
Furthermore, by seeing possible hazards and making prompt adjustments to avoid delays, project metrics assist us in streamlining the development process. They also enable us to regularly check the quality of our products and respond to any emerging technical issues. As a result, we can reduce mistakes and flaws, which will ultimately result in a more affordable software project.
These metrics keep track of the faults found at every stage of development. Project metrics, for instance, evaluate the quality of the design as software proceeds from design to coding and offer signs that influence the strategy chosen for coding and testing. Project metrics are additionally used to gauge production rate in terms of models created, function points, and lines of supplied code.
Project managers should use project metrics as a kind of secret weapon. They assist manage risks, pinpoint possible trouble spots, and enhance project quality while offering crucial insights into how a project is progressing.
#4. Manual Metrics
Quality assurance professionals carry out tests manually, step by step, without the aid of automated tools or frameworks. While it could take more time, it gives testers the ability to handle more complicated scenarios, which is a big advantage.
The following two kinds of manual test measurements aid in streamlining this procedure:
- Base metrics
- Calculated metrics
Base metrics form the basis of manual testing. As they create and run test cases, test analysts gather these crucial pieces of information. Project status reports are then created using this data, keeping test leads and project managers updated on the testing status. The total number of test cases and the total number of completed test cases are a couple of instances of basic metrics.
These metrics make advantage of the information received from basic metrics to offer deeper insights. This data is gathered and analyzed by test leads who then turn it into actionable intelligence to monitor project progress at several levels, such as module and tester. Software testing metrics of this kind are essential to the Software Development Life Cycle (SDLC) because they enable programmers to make important software modifications based on factual information.
