ASCII Consulting believes in the principle of early testing. Early test involvement not only supports effective test design, which is critically important activity when utilizing manual and automated test tool, but also provides early detection of errors and prevents migration of errors from requirement specification to design, and hence from design to code. ASCII Consultancy believes that this kind of error prevention reduces cost, minimizes rework, and saves time.
The earlier in the development cycle that errors are uncovered, the easier and less costly they are to fix. Cost is measured in terms of the amount of time and resources required to correct the defect.
A defect found at an early stage is relatively easy to fix, has no operational impact and requires few resources. In contrast, a defect discovered during the operational phase can involve several re-organisations, can require a wider range of retesting, and can cause operational downtime.
