Specifications

Goals Need to know when we’re done with the project. Need to know what is ‘good’.

Process 1. Create a list of needs 2. Prioritize needs 3. Create measurable specifications 4. Create the mapping between needs and specs 5. Benchmark competitors wrt needs and specs 6. Establish targets for specs

Create a list of needs Use interviews, observations, and experiential information Functional performance, human factors, physical requirements, reliability, life- cycle concerns, resource concerns, fabrication requirements

Prioritize needs Negotiate into priorities before pm demands it Split into wish, should, and need 1,3,9

Create measurable specifications Measurable – I know irrefutably when it is done Come from design team Quantitative versions of the qualitative Important elements of the product Be realistic wrt what can be accomplished in senior design

Need 1 Need 2 Need 3 Need 4 Need 5... Identified Needs Spec. 1 Spec. 2 Spec 3... Specs. Need 4 Need 5... Quantitative Qualitative Create the mapping between needs and specs

Benchmarking Measure competitor performance in quantitative performance areas Important to beat competitors in meaningful ways Experimented with/dissected competitors to get this

Target The objective for a measurable spec Could be a range or a number Need to make goal reasonable for the company Needs to be informed Measure and compare actual performance of completed product (testing)

Target Information Measurable specification Target Justification Measurement procedure Result Reflection
