Software Development Methodologies
Published in Marvin Gechman, Project Management of Large Software-Intensive Systems, 2019
Structured Analysis and Structured Design (SA/SD) is a traditional systems development technique that is time-tested and easy to understand. Because it describes the processes that transform data into useful information, Structured Analysis is called a process-centered technique. In addition to modeling the processes, Structured Analysis includes data organization and structure, relational database design, and user interface issues. SA/SD is used during the software requirements, Preliminary Design, and Detailed Design activities. Structured Analysis views a system from the perspective of the data flowing through it. The function of the system being designed is described by processes that transform the data flows.

Structured analysis is the process of examining the software requirements for the purposes of generating a structural model of the requirements. This activity focuses on data flowing through the system. In particular, data transformations are identified which occur in the process of delivering the required outputs from given inputs. A thorough structured analysis of the system will provide a complete and well understood set of software requirements which is highly conducive to the ensuing structured design process.
Product design improvement by a new similarity-index-based approach in the context of reconfigurable assembly processes

In cooperation with the industrial partner, manufacturer of steering columns in the automotive sector, a case study on the use of the four similarity indices for product design improvement has been realised and is presented in this article. It underlines that a comparison of different products is possible. Based on this comparison, problematic subassemblies can be identified following a formalised iterative process. The confrontation of this first case study results with the experience of the industrial partner revealed that the propositions are in concordance with what is considered possible and reasonable by the industrial partner. It emphasised the need for objective and structured analysis methods.
Object-oriented systems engineering for networked infrastructure projects
Published in Australian Journal of Multi-Disciplinary Engineering, 2020
Traditional systems engineering has used what is commonly called structured analysis to analyse user needs and develop a system model. Both structured analysis and object-oriented analysis aim to define a modular system design, but they use quite different principles to achieve it. Structured analysis and object-oriented analysis can each be implemented using MBSE tools.
