Evaluation of suppliers should be part of your Quality Management System.
Criteria are based on Quality and Delivery. Ideally you want to be monitoring suppliers that are critical to your business especially when you are an assembly plant that outsources parts manufacturing. To achieve this you can tier categorise suppliers as follows:
Tier1 : Supplies highly critical components and is in the top80% of your total spend with suppliers.
Tier2: Supplies highly critical components and is not in the top80% of your spend with suppliers.
Tier3: Supplies low critical components but are in the top80% of total spend with suppliers.
Tier4: Supplies low critical components and are not in the top80% of your total spend with suppliers.
Criteria:
1). On time delivery and in full: This means that suppliers must deliver on time (+/-1 day) and in full. You can use demerit for scoring suppliers tat are too early or too late and do not deliver in full.
2). Quality:0 non-conformance. You can use demerit for scoring suppliers with non-conformities.
You must also have a target level for which to escalate high hurt suppliers. E.g. if their score drops below80% then you must request for corrective action and or an on site visit to discuss performance and action plan. If there are repeat occurrences of quality and delivery non-compliance then a decision needs to be taken to resource and move to another supplier.
From your answer we can make out performance of the supplier. But I am looking what could be the criteria for reevaluation of supplier?
This means that all suppliers must be evaluated on a regular basis depending on their past performance according to the criteria established by the company in terms of quality, honesty in appointments (delivery dates), consistency in performance and compliance with the specifications as well as to accept prepare for audits by the customer (Second party Audit ), and based on these data the company sets standards and criteria’s table for performance , and depending to the results an decision must take to continue to deal with the supplier on or stop , or any other procedures for handling the situation.
