There are two significant differences between the PDP and the SDF. First for simplicity the PDP avoids a multitiered hierarchy. Second the rework cycle is not explicitly integrated into the PDP. These are some of the key differences between small product development and complex system development. It is not necessary to encumber a small-scale development task with a rigorous hierarchy of subsystems and components since it would take more energy to manage those tasks than to perform them. Also since rework does not ripple through a complex hierarchy its adverse impacts are not as great. I. Mapping in the Logical Domain Ulrich and Eppinger s Front-End Development Process is shown in Figure A1. As Figure A2 indicates below its key activities map directly from the Logical Domain view of the SDF in the categories of Requirements Development Synthesis and Trades. The Refine Specifications activity is handled via feedback loops in the SDF. The Plan Remaining Development Projects activity would be considered a management activity in the SDF elements of this task would also be covered in the Synthesis activity. Logical Domain mapping of the PDP to the SDF is straightforward. The organizing concept discussed in Chapter 3 above readily applies to the PDP. II. Mapping In the Time Domain Figure A3 depicts Ulrich and Eppinger s Product Development Process. It maps directly to the Time Domain view of the SDF as shown in Figure A4. Phases 1 to 4 map directly to the full life cycle view of the SDF illustrated earlier in Chapter 3. 2000 CRC Press LLC Figure A1 Ulrich and Eppinger s Front-End Process. 67 Courtesy McGraw Hill used with permission.
