A Scrum Board is a tool that helps Teams make Sprint Backlog items visible. The board can take many physical and virtual forms but it performs the same function regardless of how it looks. The board is updated by the Team and shows all items that need to be completed for the current Sprint.
Ad hoc Testing
Ad hoc testing is an informal or unstructured Software Testing type that aims to break the testing process in order to find possible defects or errors at an early possible stage. Ad hoc testing is done randomly and it is usually an unplanned activity that does not follow any documentation and test design techniques to create test cases.
Sprint planning is an event in Scrum that defines what can be delivered in the upcoming sprint and how that work will be achieved.
A board displays issues from one or more projects, giving you a flexible way of viewing, managing, and reporting on work in progress. There are 3 types of boards in Jira Software: Next-gen Board, Scrum Board, and Kanban Board.
Application Lifecycle Management (ALM)
A continuous process of managing the life of an application through governance, development, and maintenance. ALM is the marriage of business management to software engineering made possible by tools that facilitate and integrate requirements management, architecture, coding, testing, tracking, and release management.
Defect leakage is a metric that measures the percentage of defects leaked from the current testing stage to the subsequent stage as well as proves the effectiveness of testing executed by software testers.
Defect Removal Efficiency (DRE)
The defect removal efficiency (DRE) gives a measure of the development team’s ability to remove defects prior to release. It is calculated as a ratio of defects resolved to the total number of defects found. It is typically measured prior to and at the moment of release.
