Planning Support of Initial Design Process Based on Grouping and Ordering of Tasks – Design Example of an Integrated Circuit
This paper looks to support the derivation of a better design process within the early design stage, where the input and output of a task are not decided. We recognized that a good design process needs to consider the following two viewpoints.
(i) Good Task-grouping
- Each group involved has the intention to read and understand design plans from functional and structural viewpoints.
- Consideration is given to reducing the amount of influence between groups, and an optimized, whole-product design is recognized by undertaking independent design activities.
(ii) Good Order of Task-processing
- The design order should not involve a large number of design-rework and modification risks.
- The remaining areas—in which a rework is inevitable—should be clearly specified.
- Important values can be decided in the upper stream of design, where designers have a relatively high degree of freedom.
These two viewpoints are supposed to influence each other. Through them, we tried to derive a good design process by examining the group and the overall process bilaterally.
