  Developing a structured method for analyzing various aspects of a system
requires a novel methodology. This study is aimed at developing such as
methodology through combining two major matrix methods, namely, Design
Structure Matrix (DSM) and Interface Structure Matrix (ISM). Through this
paper, a business process modeling method is applied to turn a real work
project to a process model. Then that process model is written in two various
matrix forms of DSM and ISM. These two matrices are analyzed by two types of
algorithm for extracting activity levels and sub-processes. In the end, a Mixed
Matrix Model (MMM) is built upon these activity levels and sub-processes, which
can be used as a framework for the engineering of real-world systems.
