In-Depth Information
relative to DMAIC, typically experiences longer project cycle time. The goal
here is either designing or redesigning a different entity not just patching up
the holes of an existing one. Higher initial cost is because the value chain is
being energized from software development and not from production arenas.
There may be new customer requirements to be satisfied, adding more cost to
the developmental effort. For DMAIC projects, we may only work on improv-
ing a very limited subset of the critical-to-satisfaction (CTS) characteristics,
also called the Big Ys.
Completion of a market survey to determine customer needs CTS—VOC.
In this step, customers are fully identified and their needs are collected and
analyzed with the help of quality function deployment (QFD) and Kano
analysis (Chapter 12). Then the most appropriate set of CTSs or Big Ys
metrics are determined to measure and evaluate the design. Again, with the
help of QFD and Kano analysis, the numerical limits and targets for each CTS
are established. In summary, here is the list of tasks in this step. The detailed
explanation is provided in later chapters:
Determine methods of obtaining customer needs and wants
Obtain customer needs and wants and transform them into a list of the VOC
Finalize requirements
Establish minimum requirement definitions
Identify and fill gaps in customer-provided requirements
Validate application and usage environments
Translate the VOC to CTSs as critical-to-quality, critical-to-delivery, critical-
to-cost, and so on.
Quantify CTSs or Big Ys
Establish metrics for CTSs
Establish acceptable performance levels and operating windows
Start flow-down of CTSs
An assessment of required technologies
A project development plan (through TG2)
Risk assessment
Alignment with business objectives—Voice of the Business (VOB) relative to
growth and innovation strategy
TG “2”—Stage 2 Exit Criteria
Assessment of market opportunity
Command a reasonable price or be affordable
Commitment to development of the conceptual designs
Verification that adequate funding is available to develop the conceptual design
Identification of the gate keepers leader (gate approver) and the appropriate
staff
Continue flow-down of CTSs to functional requirements
