Software Development Methodologies Lecturer: Raman Ramsin Lecture 17 Methodology Engineering Department of Computer Engineering 1 Sharif University of Technology Software Development Methodologies – Lecture 17 Methodology Engineering Motivated by the prevalent belief that no one methodology fits all situations. First introduced by Kumar and Welke in 1992 as a discipline aimed at constructing methodologies to match given organizational settings or ifi d l t j tspec c eve opmen pro ec s. Later came to be known as Method Engineering, a term proposed by B i kk i 1996r n emper n ; Definition: “The engineering discipline to design, construct, and adapt methods, techniques and tools for the development of information systems” . The most well-known subfield is Situational Method Engineering (SME): concerned with the construction/adaptation of a methodology specifically attuned to the project at hand.
