1.1.1.2. Quality of the supplier
1.1.1.3. Respect of delivery dates
1.1.2. Other criteria
1.1.2.1. Technical capacity of the supplier : his own development and study service?

1.1.2.7. Localisation (in terms of logistics costs)
1.1.2.8. Reputation
1.2. for the monitoring : they are different between all companies, they depends of the sector, products, ...
1.2.1. Key metrics
1.2.1.1. Time
1.2.1.1.1. On-time delivery
1.2.1.1.2. Cycle time reduction
1.2.1.1.3. Product development time
1.2.1.2. Quality
1.2.1.2.1. Quotations errors
1.2.1.2.2. Incoming quality

1.2.1.4.1. Cost avoidance
1.2.1.4.2. Inventory reduction
1.2.1.4.3. Average cost per order
1.2.2. Lagging indicators : it's easy to calculate them. They are typically "output", it means that they appeared after an action.

2. Evaluation strategy
2.1. Segment the supply base in order to evaluate differently the suppliers => which suppliers have to be measured and what level of evaluation is applied to the different segments ?
