Deviation and incident

What is the main difference between deviation and incident?
Please give some examples…
Plz clear me whether these are incident or deviation?

  1. Temperature excursion occurs during manufacturing.
  2. One step skipped during process as per batch record.
  3. Personal working in the area is handling the product without wearing hand gloves .
  4. During transfer of material from one area to another,it’s spillaged.

Case 1,2,3, are deviations, those may have impact on the quality of the product.
Case 4 is the incident.

Case 1 & 2 are non-compliance from the Approved procedure so it can be treated as Deviation.
Case 3 & 4 are treated as Incidents.
If, Case-3 was defined in Approved procedure, it will be treated as Deviation.


When an event don’t have direct impact on product quality it may be treated as incident. but when it is directly impact product quality it is considered as deviation.
