Instructions for Use

Input areas are shaded in yellow and represent the following:

  • Planned Production Time = How long is your production time per Minutes/per h:mm:ss?
  • Scheduled Downtime = How long do you plan to have scheduled downtime during your production?
  • Unplanned Downtime = What is your estimate for unplanned downtime during your production?
  • Setup & Adjustments = How much time will you allot for setup? And estimate amount for adjustments during your production?
  • Reduced Speed = During your production, were there any moments where production slowed down?
  • Small Stops = During your production, were there any moments where production stopped for a short period of time?
  • Ideal Cycle Time/Piece = 10 seconds = 10/60 seconds/min
  • Total Pieces = How many pieces are your creating in your entire production?
  • Startup Rejects = How many rejected pieces did you have at startup?
  • Production Rejects = How many rejected pieces did you have during your production?

When you input these items, the template performs the calculations and displays these metrics in cells B(G)6, B(G)10, B(G)14, along with B(G)16:B(G)18 and B(G)20:

  • Run Time: Planned Production Time - Downtime - Setup
  • Run Rate: Run Time/Total Pieces
  • Good Pieces: The total number of pieces in your entire production that are considered "good"
  • Availability: Run Time/(Planned Production Time - Scheduled Downtime)
  • Performance: (Ideal Cycle Time * Total Pieces)/Run Time
  • Quality: Good Pieces/Total Pieces
  • OEE: 85% or better is considered "World Class"
