It is a question of beginners. However I want to make it clear for better understanding. In a training course of IATF16949, the trainer said that "Retaining a documented information means that a procedural document or equivalent for the corresponding process is a must while maintaining a documented information means that only records which serve as evidence of implementation is necessary." I wonder whether it is accurate or even correct. Please help me out on this matter. Thaaaaaaaaaaaaaaanks.
