Through this way, the company's reputation is also affected, positively if it can consistently deliver reliable and high-quality products. With an effective QA testing methodology, the cost of the overall lifecycle of the software can be reduced because QA testing ensures that software is conforming to requirements and standards; which is a fundamental stipulation in the development of life-critical products.
The maintenance cost of the software is also reduced since the software requires less modification afterward with adequate QA. Of course, the correction and modification of errors that are discovered only after the software's release and implementation can be costly and might affect the reputation of your company. So, it is important that QA procedures would identify errors sooner before the software gets released therefore resulting in the overall reduction of the entire lifecycle cost.
The Quality Assurance and testing process should spend the entire lifecycle of the product and every stage of the process of delivery production or maintenance should be covered by QA.
The concept of Quality Assurance isn't to test your software all at once at the end to report the bugs and then fix those bugs but is to create a quality product in the first place and then also test the quality product so in order for QA to work and to result in real process improvement. The entire organizational Culture has to be transformed and QA has become a continuous effort.
Regardless of what product you're developing, there are two principles the Quality Assurance follows. These are "fit for purpose" and "right first time". The "fit for purpose" means that the product does what it is supposed to do and is suitable for its intended purpose. Basically, your products should do that thing right reliably over extended periods of time so there are many ways and techniques to achieve this twofold Bowl. Good Quality Assurance starts with requirements.
The way requirements are captured, phrased, prioritized and managed greatly affects the quality of the end product. This means that requirements are formulated in a concise and easy-to-understand manner is crucial and this helps developers as well since they can understand what is required of them and more functionality is needed as the lifecycle moves on.
Audit comprises of some very systematic processes that define how the software testing is taking place in the organization. The audit team examines all the processes that are conducted at the time of testing. IEEE defines audit as a review of documented processes to ensure that the organization or a team is following all the processes as per the defined standards. Inspection can be a formal or an informal review of software requirement, designer or code.
It is conducted by a team or an individual person other than the author to check if there are any violations or deviations from the defined development standards. What is Software Quality Assurance? Defect Management Approach Quality Attribute Approach on the other hand focuses on six quality characteristics that are listed below: Quality Attributes Approach 1.
Cost of Software Quality Cost of quality is calculated by analyzing the conformance costs and non conformance costs. A conformance cost is related to: Prevention costs: amount spent on ensuring that all quality assurance practices are followed correctly. This includes tasks like training the team, code reviews and any other QA related activity etc.
Appraisal costs: this is the amount of money spent on planning all the test activities and then carrying them out such as developing test cases and then executing them.
The non conformance cost on the other hand is the expense that arises due to: Internal failures: it is theexpense that arises when test cases are executed for the first time at internal level and some of them fail. The expenses arise when the programmer has to rectify all the defects uncovered from his piece of code at the time of unit or component testing.
External failures: it is the expense that occurs when the defect is found by the customer instead of the tester. These expenses are much more than what arise at internal level, especially if the customer gets unsatisfied or escalates the software failure. Cost of Software Failure We know that a software failure is caused when: It displayslack of ability to keep up: this generally happens when the software starts aging.
As it grows old the size increases because the easiest way of adding a feature is by adding new code without touching anypart of code written earlier. Over a period of time it becomes bulky and it becomes difficult to identify the sections of code that need to be changed. Performance drop is observed: Every application generally slows down with age and tends to occupy more and more computer memory therefore it is better to switch to other software.
Surprisingly, this is one of the major reasons for increased failure rates and in order to save situation it is always better to ditch the project or give up bug fixing.
Testers are often looked upon as Software Quality Assurance professionals because the objectives of software testing as well as quality assurance are the same. As the name suggests quality assurance processes are carried out to assure the quality of the product is in line with the requirement of the client. The quality assurance professionals work on development and implementation of all the necessary processes to ensure that all the necessary procedures of software development lifecycle are followed correctly.
Quality assurance is a proactive activity that is focused on: Defect Prevention Processes Continuous improvement of this processes Software testing on the other hand is carried to identify or uncover defect and errors in the software. Our quality assurance tools ensure users have the information they need to do their jobs the right way.
