In other words, software testing is a process of verification and validation. The Six Sigma Philosophy of Cost of Quality. Cost of quality is an important concept in the project quality management knowledge area. Carrying out a complete quality audit; Installing software to gather more accurate data on quality management; Appraisal Costs. Testing has many benefits and one of the most important ones is cost-effectiveness. The poor quality costs include the cost of lost business, dissatisfied customers, poor reputation, product refunds, rework, etc. Quality costs are categorized into four main types. Cost of Quality (CoQ) is a concept used in Six Sigma to determine all the costs associated with not producing a quality product or service. Software quality measurement quantifies to what extent a software program or system rates along each of these five dimensions. But quality is not the sole responsibility of the testing team. The term refers to the costs that are incurred to prevent, detect and remove defects from products. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. CoQ influences the Cost Estimate of a project. This is a key concept for your PMP preparation. Many These include costs incurred on inspecting raw materials, work-in-progress and finished goods. An aggregated measure of software quality can be computed through a qualitative or a quantitative scoring scheme or a mix of both and … CoQ is an important consideration when you apply Life-Cycle Costing (LCC). Reliability – Refers to the level of risk inherent in a software product and the likelihood it will fail. By conducting an analysis of cost of software quality you would know what the return on that investment (ROI) is. Static testing is done to avoid errors at an early stage of development as it is easier to identify the errors and solve the errors. Two of these groups are known as prevention costs and appraisal costs.These are incurred in an effort to keep defective products from falling into the hands of customers.

Reality − There is a saying, pay less for testing during software development or pay more for maintenance or correction later. The challenge facing any software development manager is how to balance the natural tension that exists between time, cost and quality. 1.

The art of software development lies in continuous testing and improvement. The economics of Software Testing. A few examples of software quality metrics are below – these do not assess the test metrics, they only asses the quality of the software.. Appraisal costs are costs incurred to identify defective products before they are shipped off. This is because of a factor called the Cost of Poor Quality, sometimes called Cost of Quality (COQ). The software is designed to enable users to establish testing standards, effectively measure and achieve desired performance levels, and spot and address defects to further enhance quality, bring down costs, and provide applications quickly and with confidence. Software Testing - Myths. Properly tested software product ensures reliability, security and high performance which further results in time saving, cost effectiveness and customer satisfaction. The process is simple: you must test and retest a software as you move towards the completion of your product. Testing can be considered an investment.
