Productivity calculation will vary based on the process. If you could tell me what type of process it would be helpfull suggest the right calculation.
Generally Productivity is calcuated based on
Productivity = No. of Items Processed / Total target Items (day or week or month)
If you have any criteria Time bound
Productivity = No. of Items Processed or Completed within the target time DIVIDED by Total no. of Items Processed
Productivity = No.of items completed with in the assigned time / target items
If you have any criteria related to Customer Quality Review
Productivity = No. of Items Processed & Accepted by Customer DIVIDED by Total no. of Items Processed
Still If you need any clarification please mail me
Thank you for your response. Still I am not clear, can you do a rough calculation with the above data. We are doing weighted average to calculate the blended RE for the processors.
Productivity of A is 5, B is 7 and C is 12 then the blended Productivity/RE = 5 * 40% + 7 * 30% + 12 * 30% = 7.70 is the productivity. please review and let us know your view on this.
% is the volume inflow of the process or the total processed by the processor.
