What I want to convey is that it's always not possible to inspect and verify all the critical parameters unless the material is put to use and it's where the deficiencies become apparent which couldn't be detected during the physical inspection at the warehouse (prior to issue and use). By this time, the documents have already been cleared and payment released to the suppliers.
For example, the stores receive a supply of nut bolts requested by me. Now I'm asked to inspect the material. Quantity, make, dimensions, packaging etc. are OK and as such I have to sign off the 'Inspection Sheet' and accept the material since it meets the 'prescribed specifications'. Well, I use this material and after 2 weeks I happen to discover that the bolts have suffered a premature failure resulting in production loss for 4 hours. (Although the suppliers later on made a free replacement but the loss incurred by the company was many times higher than the original cost of the faulty material).
The reason (root cause) for the failure was poor quality/ craftsmanship which couldn't be inspected and verified by physical means. What one can and should do to prevent such failures.
Has anyone experienced similar problems? Please share how you succeeded in managing the issues.
