2. Multiple Domain Matrix (MDM)

Application MDM is applied in product development. It could also been used for services.
Idea  MDM is an extension for DSM. Several domains could be integrated easily. MDM consists of an individual number of DSM und DMM. E.g. if two domains should be represented (processes and resources) four arrays are needed.

If required individual relationships could be divided further, e.g. into several target groups.
Phases in the modularization process Structuration
Module structure Complex structure
Input Services, which are disassembled into singular components
Output An array of dependencies that contains more dimensional interdependencies and strengthens
Application requirements Similar to the DSM the method need already decomposed services. The most important advantage is the more dimensional illustration that enables simultaneously optimizations on more dimensions. Further cluster-algorithms for module generation are needed. In an article from Dörbecker et al. (2013) the stage of module generation isn´t descripted further, so that no details about the complexity of that stage can´t be done.
Approach
  1. Identification of the examined domains (e.g. resources and processes)
  2. Design of the DSM for each dimension (one for resources and one for processes) and of the DMM for their mapping (resources-processes and processes-resources)
  3. If needed, insert several kinds of relationships (e.g. for developers, users, target groups, operative interdependencies)
Conclusion Advantage: MDM enables a more dimensional view on the interdependencies. This leads to a higher information content as like as DSM

Disadvantage: An adequate algorithm is needed for the evaluation of the arrays and the module generation (clustering procedure). It´s complexity increases with the increasing number disproportional (e.g. there are 9 arrays if three dimensions are given)
