The Design Structure Matrix (DSM) is a project management tool that visualizes management processes, identifies and represents project elements, and assists in analyzing improvements in system dependencies. DSM is used in various industries and software programs, including system design, and can streamline processes and manage changes efficiently.
The Design Structure Matrix (DSM) is a project management tool that assists in business analysis and project management. The DSM facilitates the visualization of the management processes, allowing to identify and represent the elements in a project, following the cyclic dependencies of the tasks, as well as the flows of tasks, and assisting in the analysis of how and where to make improvements in the dependencies between the systems. The Project Breakdown Matrix management tool can produce a good flow of information between departments, so that each department, knowing the progress of other departments, can plan accordingly. The DSM is also used as a problem solver in software and systems architecture development. DSM has been used in many top tier companies since its development in the 1970s as it has proven to be beneficial in solving problems and improving organizations. The Design Structure Matrix is sometimes called the Design Precedence Matrix, Dependency Structure Matrix, and Problem Solving Matrix (PSM).
Unlike the usual project management programs that produce pages and pages of circles and arrows representing a workflow graph in the development of a piece of technology, DSM tracks information across departments and therefore can shrink a 50-page graph. for a page that is easy to prepare and can be easily modified if needed. Thus, systems engineering analysis and project management planning can be aided, as all subsystems and modules in complex systems can be represented and the flow of information between them mapped. As representations of large complex systems take shape, patterns begin to emerge in feedback loops. These patterns can be analyzed by matrix-based analysis to produce guidance for improvements to the system as a whole.
Measures for adaptations can be managed efficiently within an organization using the Project Framework Matrix. When a component in a design changes, due to the interdependencies of the other components in the design, there needs to be a flow of information that instructs the departments in charge of those other components what changes they need to make to their components. Managers can use the DSM to plan for changes, map risks, and learn the resulting costs in people, resources, and time to determine whether changes should be made and, if so, how. Because the DSM highlights iterations, task sequences, and information flows, it helps team managers streamline their processes. The Design Framework Matrix is now used across industries such as electronics technology design and production, automotive, aerospace, construction, and real estate development planning, among others, and as developed through projects at the Massachusetts Institute of Technology (MIT), Harvard, and the University of Illinois, more uses are found.
In system design, the Design Structure Matrix creates a clean programming architecture that produces a software model. Developers can represent design rules that allow and disallow dependencies and produce a contextual map of dependencies between subsystems and their dependencies in design rules. If a developer makes a change to a design rule, he can track the resulting changes across all subsets of the architecture that inherit that change. Features like these in DSM create high-specificity opportunities to keep components independent, map and keep subsystems hidden, and even manage the use of external libraries.
There are at least half a dozen software programs for using DSM as tools in research and development, and nearly a dozen or more for DSM as tools in commercial sectors. Some of these came about through research at MIT, Harvard, and the University of Illinois, and others were developed through use at the Engineering Design Center at the University of Cambridge and government agencies such as the NASA Langley Research Center. All of these programs integrate DSM with other commercial and research software to meet individual research and industry needs. These programs interface with other office, spreadsheet, and data processing programs on the market and may be adapted to similar industries adopting the use of the Design Structure Matrix in the future.
