In which circumstances would it be relevant to apply the Pareto principle (80/20 rule) to...

The Pareto principle (80/20) shows that around 80% of spend is often concentrated with 20% of suppliers. It is relevant for identifying strategic suppliers (D) that require close management and opportunities to improve or change relationships (E) for greater value. Contract expiry dates (B) and payment frequency (A) are administrative details, not Pareto analysis outputs. Cost variation (C) relates to performance analysis, not spend concentration. Responsible sourcing uses Pareto analysis to allocate resources effectively, focusing attention on the most impactful supplier relationships.
