Illustrative example: a representative scenario, not a customer story

Information Technology

ERP System Selection

Compare enterprise resource planning platforms across cost, scalability, integration capability, and vendor support. Hierarchical weighting captures stakeholder priorities while distance-based ranking provides clear vendor differentiation.

The decision problem

Seven enterprise platforms are compared before a multi-year commitment. The criteria are not flat: cost splits into licence, implementation and maintenance, and integration splits by the systems already in place. Finance, IT and the operating units want different things, so the weighting is the part of the process that has to be defensible.

Which method, and why

AHP carries the criterion hierarchy natively, and its consistency ratio catches a set of stakeholder judgements that contradicts itself. TOPSIS gives a distance-based ranking with clear separation between vendors. WASPAS combines a weighted sum and a weighted product view; where those two disagree, the difference points to a vendor whose profile is uneven rather than uniformly strong.

What you get out

Ranking and scores

Every alternative with its score, its rank and the intermediate matrices that produced them.

Weight sensitivity

One criterion weight moves at a time, so you see exactly where the leader changes.

Method agreement

When more than one ranking method is run, the orders are compared with Spearman rho and Kendall W.
