WebIn this article, the tool Design Structure Matrix (DSM) is explained. The theoretical concepts and applications are explored with a focus on the application of DSM within program management. Using Pratt and Whitney’s PW4098 engine development as a case, the application of DSM as an Alignment Matrix is explained. In statistics and in particular in regression analysis, a design matrix, also known as model matrix or regressor matrix and often denoted by X, is a matrix of values of explanatory variables of a set of objects. Each row represents an individual object, with the successive columns corresponding to the variables and their specific values for that object. The design matrix is used in certain statistical models, e.g., the general linear model. It can contain indicator variables (ones and zeros) that ind…
