Concurrent Design in Software Development Based on Axiomatic Design

Abstract

To shorten the lead-time of software, the design tasks should be arranged reasonably. Development process reconfiguration is the key to the concurrent design. Axiomatic design builds the functional-structure model of products by zigzag mapping among domains. The independence axiom demands that the independence of the functional requirements should be maximized. The relationship between tasks is established by analyzing the design matrix. The diagonal matrix shows that the design tasks are mutually independent, and can be concurrently processed so that the overall developing time can be greatly shortened. The triangular matrix shows that the design tasks should be processed sequentially so that the whole process can be managed effectively. By using axiomatic design to analyze the design tasks, the design process can be arranged reasonably and the lead-time can be shortened. The module-junction structure diagram shows the sequence of the software development.
