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.
|1||Percentage of packages with excess (2 or more) cookies (currently at 95%)||9||%|
|2||Weight of cookies in package||9||grams|
|3||Follows Wegmans' sanitation standard||3||Y/N|
|4||Requires training that takes X mins||5||minutes|
|6||Creates clear separation of product for packaging||9||Y/N|
|7||Throughput||9||average packages per hr|
- Importance Scale:
9 = These metrics will be the main focus of this project.
5 = These metrics will be a secondary focus of the project if time allows.
3 = These metrics will not be focused on unless the main and secondary metrics have been addressed.
The metrics, or engineering specifications, that you created in the preceding list should be directly related to the customer needs. In other words, if you have created an engineering specification, it should have some relationship to a need imposed by the customer or the marketplace. Use the table below to map your customer needs against the metrics (or engineering specifications). In many design and product development circles, the rows along the left is often referred to as the voice of the customer, while the columns across the top are often referred to as the voice of the engineer.
|Needs and Metrics||Percentage of packages with excess cookies||Weight of cookies in package||Follows Wegmans' sanitation standard||Requires training that takes X mins||Changeover Time||Creates clear separation of product for packaging||Throughput||Cost|
|Customer Need 1.1||X||X||X|
|Customer Need 1.2||X||X|
|Customer Need 1.3||X||X|
|Customer Need 1.4||X||X|
|Customer Need 2.1||X||X|
|Customer Need 3.1||X|
|Customer Need 3.2||X|
|Customer Need 4.1||X||X|
|Customer Need 4.2||X||X|
|Customer Need 5.1||X|
|Customer Need 5.2||X||X|
|Customer Need 5.3||X|
|Customer Need 6.1||X|
|Customer Need 6.2||X|
|Customer Need 6.3||X|
|Customer Need 6.4||X|
|Customer Need 7.1||X|
Step 2. Collect Competitive Benchmarking Information
- Benchmarking Summary:
There are many systems out there that partially do what this project is attempting to create. However, there is not a system that can satisfy all of the customer needs. Systems like conveyor belt scales do not provide the clear separation that is required and systems that automate the entire packaging process do not provide the randomization the customer is looking for or fall within their budget. Therefore the conclusion that there is nothing to provide a benchmark for this project can be drawn.
|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|
|1||Need 1.1, 1.2, 1.3, 1.4, 2.1||Percentage of packages with excess (2 or more) cookies (currently at 95%)||9||%||60% (elimination of packages with 6 or more extra cookies)||0% (elimination of packages with 2 or more extra cookies)|
|2||Need 1.1, 2.1||Weight of cookies in package||9||grams||422 +/- 5||397 +/- 5|
|3||Need 6.1, 6.2, 6.3, 6.4||Follows Wegmans' sanitation standard||3||Y/N||N||Y|
|4||Need 4.1, 5.1, 5.2, 5.3||Requires training that takes X minutes||5||minutes||60||15|
|5||Need 4.1, 4.2, 5.2||Changeover time||5||minutes||20||5|
|6||Need 1.1, 1.2, 1.3, 1.4, 3.1, 3.2||Accurately separates product for packaging||9||Y/N||Y||Y|
|7||Need 4.2||Throughput||9||average packages per hour||1500 +/- 2.5%||1700 +/- 5%|
|8||Need 7.1||Cost||9||$||< $10,000||< $5,000|
