Cooja simulator coding implementation Quality Assurance

QA, QC, and testing are a part of Quality Management however QA is focusing on preventing defect while QC is focusing on identifying the defect andTesting is focusing onexecuting a system all are much similar but not the same and interchangeable. Which is tightly linked and sometimes it is very difficult to identify the differences. Here all are related to each other but they are having different approaches.

Quality Assurance:

Quality Assurance will mainly focuses on preventing the defects. It ensures that the techniques, methods, approaches, and the working processes are designed for the projects are implemented correctly. For Successful software projects, critical strategic and competitive necessity for firms in all industrial sectors today. However, due to cost overruns, schedule delays, unfilled requirements and poor quality, which reported that 30% of software projects are perceived to be successful. It describes the causes of project failure and critical success factors for effective management projects, yet projects still continue to fail.  To overcome the systemic causes of project failure we propose a unified definition of software quality assurance (SQA). It is a practice of monitoring the software resources and its methods used in a project to ensure proper quality of the software. It mainly focuses on preventing defects, controlling the risks and provide a framework for assuring the development and project management life cycles.

Quality Control:

Quality control (QC) is a process by which entities review the quality of all factors involved in production likewise in software quality control it is the set of procedures used by the companies to ensure that a software product will meet its certain quality goals at the best value to the customer, and to continually improve the organization’s ability to produce software products in the future.

Testing:

Testing is a common activity aimed to detecting and solving technical issues in the software source code and assessing the overall product usability, performance, security, and compatibility. It has a very narrow focus and is performed by the test engineers in parallel with the development process or at the dedicated testing stage depending on manual and automation testing approach to the software development cycle.

Overall QA, QC and Testing are required to ensure a successful product launch and continued success as the program continues to run. Changes in data are sometimes not reported and having a strong QC system assists in detecting issues
