| Summary: | This research deals with a fonnal design method called "Design Equations for
Systems Analysis", or DESA. This method reduces system complexity, and has been
demonstrated to effectively reduce the complexity of human-machine systems. It also
increases the usability of products. The author summarized two other design methods
that reduce system complexity - Axiomatic Design (AD) and Design Structure Matrix
(DSM) - and explained their differences from DESA. A case study was then
presented to demonstrate the ability ofAD and DSM to complement each other. Since
DESA builds on AD, it can complement DSM similarly. The author revised the
framework that DESA utilizes. A tenninology was established to define the technical
tenns in DESA. DESA was then employed to design an inspection method that
evaluates usability. It was also employed to reduce the complexity of an objectoriented
software system. These two applications of DESA are presented as case
studies. These two case studies respectively demonstrate that DESA designs for
usability and effectively reduces the complexity of object-oriented software systems. |
