| Architecture - | (Software Engineering) the overall structure of software components, the data and/or content that components manipulate, and the relationships between them |
| Aspect-oriented development - | (Software Engineering) a development approach that emphasizes "concerns" (also called "aspectual requirements" that incorporate features, functions and information content) that cut across multiple system functions |
| Automated estimation tools - | (Software Engineering) tools that help in estimating project cost or effort |
| Automatic code generation - | (Software Engineering) tools that generate source code from a representation of software that is not source code |
| Baseline - | (Software Engineering) a point at which some deliverable produced during the software engineering process is put under formal change contro |
| Basis path testing - | (Software Engineering) a white box test case design technique that used the algorithmic flow of the program to design tests |
| Basis set - | (Software Engineering) the set of tests derived using basis path testingBehavioral modeling - |
| Beta testing - | (Software Engineering) testing that is conducted by the user |
| Black box testing - | (Software Engineering) testing that does not focus on the internal details of the program but uses external requirements |
