Cost Time Report (CTR)

Share This Post

Prepare a Cost Time Report (CTR) for each package to calculate the budget in terms of inspection man days required during manufacturing.

 

You can use equipment criticality to assign a factor for calculating man days.

 

For example, forĀ  an equipment with criticality ā€œ1ā€ , assign a factor of ā€œ1.6ā€;

 

Now; if the equipment takes 6 months to be manufactured; considering 5 working days per week, you would need 6 X 22 (22 being working days in a month) multiplied by 1.6 (package criticality factor) = 211 man days of inspection.

 

For criticality ā€œ2ā€ you can use a factor of ā€œ1ā€ and so on.

 

Criticality ā€œ3ā€ normally needs a final inspection only; while criticality ā€œ4ā€ items are normally inspected at the point of receipt or at site.

 

You may want to add 25% to the total budget to account for uncertainties and any surprises such as:

  • Ā repeat inspection due to NCR,
  • Ā cancelled inspection by supplier,
  • Ā delays,
  • Ā enhanced inspection due to supplier’s poor performance.
