Modular function deployment

Modular function deployment (MFD) is a systematic method and procedure for company-supportive product modularization.

Five steps

MFD consists of five major steps. It starts with quality function deployment (QFD) analysis to establish customer requirements and identify important design requirements with a special emphasis on modularity. Functionality requirements for the product are analyzed, and technical solutions are selected. This is followed by systematic generation and selection of modular concepts, in which the module indication matrix (MIM) is used to identify possible modules by examining the interrelationships between "module drivers" and technical solutions.

MIM also provides a mechanism for investigating opportunities of integrating multiple functions into single modules. The expected effects of the redesign can be estimated, and an evaluation can be carried out for each modular concept. The MIM is then re-used to identify opportunities for further improvements to the single modules.
