Flow Efficiency helps you measure the actual work time against the Lead time. So, the efficiency can be measured by dividing Work Time by the combination of Work Time and Wait Time, and higher is the percentage, better and smoother is the process having less waste in the system and more agility to turn idea or request into a workable feature.

Applying Filters

You can apply filters based on card attributes and the value stream stages to refine your data for the analytics. Moreover,  the time range for the analytics can also be adjusted using the Temporal Range Filter. Read more about them here.

Flow Efficiency Scatterplot

This is a Scatter plot of card flow efficiency. Flow efficiency is defined as (work time / total time). Work time is defined as total time spent in In Progress columns. We subtract the Block time from effective work time as the most common reason for blocking among our customers is to indicate resource unavailability. Thus, the formula used here is the effective work time / total time. Flow efficiency of a card becomes available when a card exits.

Different shapes indicate the type of exit:

  • Circle: move forward or is archived
  • Triangle: move back
  • Square: move to other value-stream
  • Diamond: cards that were deleted or discarded

Flow Efficiency Histogram

A histogram of flow efficiency for cards that exit the selected value-stream region in the time interval selected in the Time Range Filter and pass other selected filtering criteria. The x-axis represents the flow efficiency in buckets of 10% and y-axis represents the count of cards whose flow efficiency falls in each bucket.

Work Time vs. Wait Time

This correlation graph shows the relation between effective work time and wait time for the cards that have completed their journey through the selected region of the value stream. Effective work time is defined as time spent in In-Progress columns subtracting the block time while in these columns.
The block time is considered to be wait time and therefore is added to the wait time. The x-axis represents wait time, the y-axis represents work time. The flow efficiency is shown using radial lines originating from [0,0].

Different shapes indicate the type of exit:

  • Circle: move forward or is archived
  • Triangle: move back
  • Square: move to other value-stream
  • Diamond: cards that were deleted or discarded
