Spec vs. Specs
A spec consists of a metric, a unit, and
a value
Specs has a set of specs.

Target vs. Final Specs
Target specs: the hope and aspiration
of the design (ideal and marginal)
Refined specs: trade-offs amongdifferent desired characteristics.

Nature of Specifications
The reference point for functionality design and
quality planning
Poin referensi dari fungsi desain dan rencanakualitas
A product assembly usually requires a hierarchy
of specs, for the final product and each of its
components
Perakitan produk biasanya berasal dari hirarki
specs. Untuk produk final dan dari setiap
komponen

The Product Specs Process
1. Set Target Specifications Based on customer needs and benchmarks
Develop metrics for each need
Set ideal and acceptable values2. Refine Specifications
Based on selected concept and feasibility testing
Technical and economic modeling
Trade-offs are critical
3. Reflect on the Results and the Process
Critical for ongoing improvement

Procedure for establishing
target specifications1. Identify a list of metrics and measurement
units that sufficiently address the needs
2. Collect the competitive benchmarkinginformation
3. Set ideal and marginally acceptable target
values for each metric (using at least, at
most, between, exactly, etc.)
4. Reflect on the results and the process

Process for setting the final
specifications1. Develop technical models to assess technical feasibility. The
input is design variable and the output is a measurement using
a metric.
2. Develop a cost model of the product.3. Refine the specifications, making tradeoffs, where necessary to
form a competitive map.
4. Flow down the final overall specs to specs for each
subsystem (component and part).
5. Reflect on the results to see Whether the product is a winner, and/or
How much uncertainty there is in the technical and cost model, or
Whether there is a need to develop a better technical model.
