Establish Target Specifications
Table of Contents
Step 1. Prepare the List of Metrics
The table below presents the metrics, or engineering specifications, that will be used by the team to design against.
|2||Low power to operate||nominal|
|6||High customer usability||+|
|7||High control accuracy||nominal|
|8||High sensing accuracy||-|
|9||High page rate||-|
|11||Small machine footprint||+|
|12||Software Kill Switch||-|
|13||Hardware Kill Switch||-|
|17||Low time to complete||nominal|
|18||High fusing quality||nominal|
The table below compares the engineering metrics to the customer needs.
|Needs and Metrics||Engineering Metric 1||Engineering Metric 2||Engineering Metric 3||Engineering Metric 4||Engineering Metric 5||Engineering Metric 6||Engineering Metric 7||Engineering Metric 8||Engineering Metric 9||Engineering Metric 10||Engineering Metric 11||Engineering Metric 12||Engineering Metric 13||Engineering Metric 14||Engineering Metric 15||Engineering Metric 16||Engineering Metric 17||Engineering Metric 18|
|Simulate roller based fuser||3||1||3||3||10||3||3|
|Project deadline (22wks)||9|
|Stamp Roller Comparison||3||1||1||9||9||1||3||9|
|Control and Measurement of Speed||9||9|
|Control and Measurement of Temperature||9||9|
|Control and Measurement of Pressure||9||9|
|Modular Roller Materials||9|
Step 2. Collect Competitive Benchmarking Information
Relatively few Sr. design projects start from a clean sheet of paper. In most cases, there are some baseline solutions or products that could meet the vast majority of the customer's needs.
Write one or two paragraphs about each benchmark solution from the market place. Include a picture of the product, preferably illustrating the product in use or operation.
- Benchmark 1
- Describe the first benchmark solution here.
- Benchmark 2
- Describe the second benchmark solution here.
- Benchmark 3
- Describe the third benchmark solution here.
Use this table below to compare how pre-existing solutions should compare against the design team's efforts. See the example Table 5-6 on Page 80 of the text by Ulrich and Eppinger.
|Metric No.||Need Nos.||Metric||Importance||Units||Benchmark 1 Value||Benchmark 2 Value||Benchmark 3 Value|
Step 3. Set Ideal and Marginally Acceptable Target Values
Given the customer needs, awareness of the marketplace, and resource limitations of the current project, assign preliminary engineering specifications on each of the metrics. In addition to setting the nominal or target value or each specification, provide guidance to the team on the ideal value or direction that the team should strive for, once the nominal target values have been realized.
|Metric No.||Need Nos.||Metric||Importance||Units||Marginal value||Ideal Value|
