Pugh concept selection analysis
The concept selection according to Pugh (synonymous: concept selection, concept selection, concept analysis, concept selection analysis) is a relatively simple, systematic comparison according to weighted criteria. The process was developed by Stuart Pugh in the late 1980s. It is also used in connection with Six Sigma .
execution
The concept selection is usually carried out as a table with the following columns:
- Criteria according to which the concept should be selected
- Weighting of the criteria (mostly 1–5)
- Benchmark or comparison concept (fictitious concept or current solution)
- Concept 1… n
steps
The evaluation process is based on the following steps:
- Collecting the evaluation criteria
- Weighting according to importance for the solution
- Determination of the comparison / benchmarks
- Establishing the alternative concepts
- Evaluation of the alternatives in comparison to the benchmark (see evaluation and evaluation)
- Analysis of the evaluation and attempt to develop a hybrid concept from the best evaluations.
Assessment and evaluation
The evaluation is carried out using numbers or symbols. +, S, - or +1, 0, –1 are common. These mean better, the same or worse.
As a further differentiation in better and much better z. B. rated with + and ++. This also applies to the negative rating. The evaluation is carried out on the one hand by pure counting of the ratings and by weighted counting.
