No matter how well we plan and execute software development, defects are generated and can escape to the customers. Failure to quickly resolve software problems leads to negative consequences for our customers and increases internal business costs. A quick deterministic
method to prioritize problems and implement their solution helps to reduce cycle time and costs. Achieving this goal requires several steps. The first is to determine a model that links problem resolution performance to institutional variables and problem characteristics. Statistical Design of
Experiments (DOE) is a tool that provides data requirements for estimating the impacts of these variables on problem resolution. Once data has been gathered, the results of statistical analysis can be input into a mathematical optimization model to guide the organization.
This paper describes such an analysis.
Lights. Camera. Action! This article suggests using multimedia tools that combine a visual display, voice recording, and screen annotations to illuminate the steps required to isolate a bug. The result is an effective means of simplifying the process for both testers and developers. Yogita explains the benefits and risks associated with producing your own bug movie.
With all of the advancements in defect tracking systems within the past few years, companies are still using the same ambiguous, canned fields known as Severity and Priority to categorize their defects. Let's examine a better way to assign importance to a defect.
This Software Test Incident Report template is based on the IEEE 829-1998 test standard and additional information added from various sources—actual test plans, instructor experience, student comments, etc.
Defect counts are often considered as measurements of product quality. However, the most important defect count in that respect is by definition unknown; the number of undiscovered errors. Defect counts can be used as indicators of process quality. In doing so, one should avoid assuming simple causal relations. Defect counts can provide useful information but have to be presented with care.
