Use the Cycle Time Bar Chart to compare the cycle times for multiple operations. This analysis is useful when trying to balance either a cell or a sequential series of process steps. It highlights the "waste of waiting".

Answers the questions:
  • Which operations are more heavily loaded?
  • How much slack there is in the under-loaded operations?
When to use Purpose
Pre-project Evaluate operational cycle times and to assess line balance.
Mid-project Explore and document changes in cycle times and to reassess line balance.


This form uses the operation names and cycle times from a process map.


  • If there are multiple work stations for a single process step, enter the cycle time on the process map as the cycle time divided by the number of stations. For example, if, for the process step "drill hole", there are 4 machines, and the cycle time for one machine to drill a hole is 2 minutes, the cycle time for that process step is 30 seconds.
  • To complete a line balance of a proposed cell whose steps do not exist on a process map, you must first create a process map with those steps. This can be as minimal as simply placing shapes with no connectors or logic and simply entering names and cycle times.


  1. Fill out the information header.
  2. This tool requires a process map with cycle time information. To create a chart, select existing activities to populate the table.
  3. You can enter new cycle times in the form to see dynamic changes to the chart, but note that this will also change the cycle times in the process map.
  4. Record your conclusions.
