| Modular design - | (Software Engineering) a design approach that stresses modularity |
| Modularity - | (Software Engineering) an attribute of a design that leads to the creation of high quality program components |
| Object-oriented design (OOD) - | (Software Engineering) a technique for translating the OOA model into an implementation model |
| OCL (Object Constraint Language) - | (Software Engineering) a supplement to UML, this formal language allows a software engineer to construct unambiguous statements about the characteristics of various design model elements |
| Pair programming - | (Software Engineering) two people work together (side-by-side) to design and construct a software component, providing real-time problem solving and quality control. |
| PDL - | (Software Engineering) program design language; a combination of natural language with programming language-like constructs |
| Preliminary design - | (Software Engineering) creates representation of the data and architecture |
| Procedural design - | (Software Engineering) creates representations of algorithmic detail within a module |
| Refactoring - | (Software Engineering) changing software in a way that improves its internal structure but does not change it external behavior; often conducted iteratively as design evolves into code. |
| Reverse engineering - | (Software Engineering) trying to develop design models or an understanding of design using program code as a starting point |
