Andy Church is back on Product Inspections
Product Inspections report
- Allocation time for inspection on 2,000 units
- When is the inspection going to be done and impact on shipping on time
- Last thing a buyer wants is an inspection delaying shipping
Plan time in for Product Inspections
- Understanding the timeline at the beginning
- You can then hold the factory to the date for inspection
- Product Inspections are a 2 day window
- If a problem is found then make sure the factory has time to put things right before they need to be shipped
- Ideally 3-5 days before they need to be at the Port for shipping
- Regardless of the order size it’s still a day at least and turnaround time on the report
- Add in a week to Factory timelines as they are often aggressive and slips happen
- Allow for delays by the factory
AQL Tables – 100% inspections
- Not always effective
- Inspector is fatigued
- 300 sample size is the number of pieces an inspector can inspect in a given day
- An order size bigger than this is a challenge for 100%
- Inspector fatigue impacts the quality of the inspection as the high volume of units inspected through the day gets lower as time goes
- Decision fatigue also has a part to play in this (Steve Jobs wearing the same outfit each day to preserve his decisions quota)
- Acceptance Quality Limit = AQL (worst level of quality your able to tolerate)
- An AQL chart is out there and it’s quite simple once you understand
- What level fo defects you willing to accept
- Then the order quantity
- Then sample size
- And the number of defects can be observed and still pass
- Accept and Reject criteria is on the chart for you to decide what’s acceptable
Product Inspections Levels Setting
- Three levels of defects
- Critical
- Always a Zero (One defect at this level then reject)
- Anything that would cause injury to or safety hazard to the user
- Electrical: shock
- Sharp toys
- Needle in plush teddy bear
- Major and Minor
- 2.5 defects (5%)
- 18 inches from eyes and arms length
- Affect usability or saleability
- Carton is crushed
- Missing components
- Put it together and can’t use it
- Would be returned
- Minor
- 4.0 defects
- Not affect usability or saleability
- But not as specified
- Scratches, etc
- Unlikely to be returned
- Critical
- You may want to lower the defect numbers on these levels depending on your risk, standards and costs
- Upto you to decide with you and the Factory before you place the order to set the AQL levels
Define at Order time
- AQLs should be established and included in your order to he factory
- The factory should be able to follow these in their own internal quality processes
An Inspection Fails
- Agree up front what happens if the inspection fails
- You may decide to pay the re-inspection costs
- Most times the factory is responsible for the re-inspection costs
- The factory needs to know they have responsibility
- Factories agree to these up-front to avoid upset
- Use as a bargaining tool
- If an inspection fails for minor defects – buyers will still purchase but it’s got minor scratches
- If the minor defect level was exceeded – you might ship it but agree a discount to take it as is and meet your ship date
- Some agree to replace any returns on the next shipment – so all returns are compensated
Inspection Provider
- Should be willing to have a conversation with you about the process
- What you need to consider from a defect point
- The buyer and factory should be an expert in their product but…
- Working with the Factory and Inspections service should cover what’s needed in defect terms and levels and agree what the inspection criteria should be
- For Danny – this inspection step is simply a corner you can’t cut! The cost to you of a failed products that you have to pull out of hte Warehouse
