What are the most effective performance indicators for multi-criteria decision analysis?
Multi-criteria decision analysis (MCDA) is a method of evaluating and ranking alternatives based on multiple criteria, often with conflicting objectives. MCDA can help data analysts make informed and transparent decisions in complex and uncertain situations, such as selecting the best location for a new facility, prioritizing projects, or choosing the optimal strategy. However, to apply MCDA effectively, data analysts need to use appropriate performance indicators to measure and compare the alternatives. In this article, we will discuss what are the most effective performance indicators for MCDA and how to select them.

The first step in MCDA is to define the criteria and attributes that reflect the objectives and preferences of the decision-makers and stakeholders. Criteria are the broad categories that describe what is important in the decision problem, such as cost, quality, safety, or sustainability. Attributes are the specific measures that quantify the criteria, such as dollars, ratings, percentages, or units. The criteria and attributes should be relevant, clear, comprehensive, and measurable. They should also be independent, meaning that they do not overlap or influence each other.

Criterias help in determining the approach (High level design) to take to solve a problem and which factors or variables take more precedence over others. Attributes not only help in measuring the success of criteria implementation but also helping low level implementation and modifications to ensure that the final product is within criteria limits and definition of done.

Define clear criteria and attributes relevant to the decision context, ensuring they cover all essential aspects for evaluation while avoiding redundancy or overlap.
The second step in MCDA is to construct a performance matrix that shows the scores of each alternative on each attribute. The scores can be obtained from data sources, expert judgments, surveys, or models. The performance matrix should be consistent, accurate, and complete. It should also be normalized, meaning that the scores are converted to a common scale, such as 0 to 1 or 1 to 10, to allow for comparison. Normalization can be done using different methods, such as linear scaling, rank order, or goal achievement.

The third step in MCDA is to aggregate and rank the alternatives based on their scores and weights. Weights are the relative importance of the criteria and attributes, which can be determined by the decision-makers or stakeholders using various techniques, such as pairwise comparison, rating, or swing weighting. Aggregation is the process of combining the scores and weights into a single value for each alternative, which can be done using different methods, such as weighted sum, weighted product, or outranking. Ranking is the process of ordering the alternatives from best to worst based on their aggregated values.

In multi-criteria decision analysis, key performance indicators include creating a composite score through aggregation, applying weighted scoring, using a ranking methodology, and conducting sensitivity analysis. These methods provide a balanced view of performance, essential for informed decision-making.

Employ appropriate aggregation methods (weighted averages, scoring models) to combine criterion scores and rank alternatives, reflecting their overall performance against the defined criteria.
The fourth step in MCDA is to perform sensitivity analysis to test the robustness and reliability of the results. Sensitivity analysis is the process of changing the inputs or assumptions of the MCDA model, such as the scores, weights, or aggregation methods, and observing the effects on the outputs or rankings. Sensitivity analysis can help data analysts identify the key drivers of the decision, assess the uncertainty and variability of the data, and explore different scenarios and trade-offs.

Run sensitivity tests to see how rankings change when: Varying PI weights: Increase cost weight, see if budget-friendly options climb rankings. Adjusting PI values: Shift customer satisfaction scores, analyze impact on customer-focused choices. Using different aggregation methods: Compare MAUT rankings to weighted averages to assess preference variations. By analyzing these "what-if" scenarios, you: Identify robust decisions: Options consistently ranked high across changes are strong choices. Uncover critical PIs: Track rankings that shift most, revealing key decision drivers. Build confidence in your choice: Understand potential shifts Sensitivity analysis is about understanding how your decision landscape reacts to potential changes.
The fifth step in MCDA is to validate and communicate the results to the decision-makers and stakeholders. Validation is the process of checking the validity and quality of the MCDA model, such as the logic, consistency, and transparency of the criteria, attributes, scores, weights, and aggregation methods. Validation can be done using various tools, such as consistency ratio, concordance index, or discordance index. Communication is the process of presenting and explaining the results in a clear, concise, and convincing way, such as using tables, charts, graphs, or dashboards.

Validate your PIs & scores: Data consistency checks: Ensure accurate calculations, no typos or errors. Stakeholder feedback: Engage decision-makers, experts, to refine PIs and weights. Sensitivity analysis: See how rankings change under different assumptions. Communicate & build buy-in: Visualize your data: Show clear charts, graphs, to explain rankings and trade-offs. Highlight key insights: Focus on critical PIs, impactful scenarios from sensitivity analysis. Tailor explanations: Match audience expertise, explain technical aspects simply. Remember, clear communication and stakeholder buy-in are crucial for implementing your well-informed multi-criteria decision.

Validate the model's outcomes against real-world scenarios or expert opinions, ensuring reliability. Effectively communicate results and methodology to stakeholders, ensuring transparency and understanding.
The sixth step in MCDA is to evaluate and improve the MCDA model and the decision process. Evaluation is the process of measuring and monitoring the performance and outcomes of the decision, such as the efficiency, effectiveness, satisfaction, or impact of the chosen alternative. Evaluation can be done using various indicators, such as cost-benefit analysis, return on investment, key performance indicators, or balanced scorecard. Improvement is the process of learning and adapting from the feedback and experience of the decision, such as identifying the strengths, weaknesses, opportunities, or threats of the MCDA model and the decision process. Improvement can be done using various methods, such as benchmarking, best practices, or continuous improvement.
