ABSTRACT
This chapter illustrates the modeling process with a case study conducted in the field of space systems product development. Systems developed for space applications, whether for ground systems or for satellites, are often large, complex, and software-intensive. These systems are developed for missions critical to both government and commercial interests and have to meet schedules for deployment. Static tools, such as size estimation algorithms, Program Evaluation Review Technique (PERT) charts, and Gantt charts are typically used to produce schedules, but they lack feedback loops for representing the dynamic behavior of rework cycles. Thus simulation, with its ability to represent dynamic behavior in product development, was indicated. Understanding the TaF cycle dynamics enabled recommending a set of guidelines for reducing the duration of this cycle, ordering the first four based on the relative influence of factors.
