Edwards Deming, a statistician, a doctor of physics, and a pioneer of quality in production, was the first person to establish and articulate the cause-and-effect link between product quality and profits. He was also the first person to tie product quality to profits. In the 1980s, the accomplishments he had achieved while working at Toyota’s facilities were referred to as a “miracle” in Japan.
The happiness of one’s customers and the pursuit of continuous improvement at all stages of product creation are two fundamental tenets of Deming’s management philosophy. This enhances customer qualities, helps to assure competitiveness, and, as a result, increases profitability.
What is quality assurance in software development?
When responding to this question, you should always keep in mind that this criterion is in some ways subjective and cannot be seen from a single perspective. In practice, a software product is evaluated from four vantage points: the perspective of the developers, managers, customers, and quality assurance engineers.
The quality of the product is determined, as previously said, by the aforementioned professionals according to their own standards. For instance, the customer may define “quality” as the complete absence of any flaws as well as the successful resolution of the problem for which it was intended.
- For the developer and management, quality is shown by a clear solution to the business problem and the lack of software faults that prevent its effective use.
- For the tester (or QA Engineer), the degree of quality must be much above average. At this level, developers must provide a product devoid of faults that substantially detract from the user experience.
Conforming to the international quality standard, the quality is measured.
This global quality standard establishes:
- How well functioning fulfills requirements;
- Whether it is appealing, intuitive, and user-friendly;
- How consistent the system is;
- Whether material resources are used effectively;
- How uniformly it will provide advantages across various contexts, circumstances, and configurations;
- The work required by the project team to plan the scaling, implement modifications, test, and troubleshoot the performance of the system.
How much does inadequate software cost?
Frequently, software QA consulting services attempt to defend a software product of questionable quality via the client’s eyes by using the Agile Manifesto’s phrase “functioning software above thorough documentation.” Although this strategy results in a product that is ready for launch, it may incur extra expenses. Even a single problem might need considerable time and resources to fix. Let’s compute!
Typically, there are 11 stages:
- Confirmation of errors;
- Elimination of errors;
- Prevention of errors
- Error management
- Avoiding errors
- Support engineer
- QA engineer
- Final user
You should also examine the expenses associated with a potential loss of income and reputation.
A real issue is how to at least limit the number of such errors. As coding is a creative endeavor, it is impossible to expect coders to consistently produce bug-free code. Instead, it is preferable to consider how you and each team member can enhance the process at each level.
The team shares responsibility for quality.
Conclusion – Software Quality Assurance as an Integral Process
The whole team, not just the QA engineer, contributes to the creation of high-quality software QA consulting services. Customer comprehension of the desired outcome, a well-thought-out testing plan, and an appropriate technique are the keys to a product’s success.
