Utility Value Analysis
This post is a term definition for Utility Value Analysis (UVA) – including exam questions, examples, and tags.
In a Nutshell
Utility Value Analysis is a multi-criteria method for evaluating alternatives when quantitative and qualitative criteria must be considered. The result is a traceable ranking based on weighted point values.
Compact Technical Description
UVA orders alternatives based on:
- Criteria catalog (incl. must/knockout criteria)
- Weighting (sum of weights = 1)
- Normalized evaluations (e.g., 0–10)
The overall utility value is calculated as the sum of weight × partial utility per criterion. Sensitivity analyses check whether the ranking remains stable if weights/evaluations change.
Important: Perform knockout checks first so that inadmissible alternatives are not “extrapolated.”
Exam-Relevant Key Points
- Clearly separate must/knockout vs. should criteria
- Weight sum must equal 1
- Scale consistency: “higher = better” (invert cost criteria)
- IHK: Justify and document weighting + data sources
- Manipulation risk: Four-eyes principle
- Coupling with TCO/ROI possible
- Documentation requirement: matrix, assumptions, versioning, approval
Core Components
- Goal definition
- Criteria catalog incl. knockout
- Scales/utility functions
- Weighting methods (pairwise comparison/percentage)
- Evaluation matrix
- Normalization + aggregation
- Sensitivity analysis
- Visualization (bar/spider/heatmap)
- Roles/approvals
- Plausibility check
Simple Practical Example
Alternatives: Framework A, B, C
Criteria: Performance, Maintainability, License Costs, Community
Weights: 0.35, 0.30, 0.20, 0.15
Evaluations (0–10), cost criterion inverted
Ranking: highest weighted sum wins
Advantages and Disadvantages
Advantages
- Combines hard and soft criteria
- Transparent decision process
- Sensitivity analysis possible
- Combines well with TCO/ROI
Disadvantages
- Subjective weights
- Scale choice can distort
- Compensation problem (very good can offset very bad)
Typical Exam Questions (with Brief Answers)
- What is utility value analysis used for? Structured selection from alternatives based on weighted criteria.
- Must vs. Should? Must/knockout criteria exclude; should criteria flow into the score.
- How is utility value calculated? Sum of (weight × evaluation), weight sum = 1.
- Why sensitivity analysis? Checks ranking stability.
Free Response
UVA is ideal for software/tool/architecture decisions. Key factors are clear criteria, traceable weighting, consistent scales, and complete documentation.
Learning Strategy
- Choose a selection problem from everyday life and gather criteria.
- Sketch the UVA process as a flow.
- Calculate a complete matrix under time pressure.
- Check scale consistency + weight sum.
