Metric Series - Yield Calculation

In this new series we will be highlighting how each of the key metrics are calculated.  If your org is brand new to andon then of course you won't have a large data set to show historical metrics.  In this case the demo org [instructions to join here] can be a great resource for viewing metrics as it has a built-in comprehensive historical data set.

Today we want to highlight the Yield metric.  For each station, yield is calculated by taking the # of 'pass' units produced and dividing by the total number of units; in short: # of pass/(# of pass + # of fail).  For each line, yield is calculated by multiplying all of the individual station yields together. 

With andon you can graph line and station yield on the same chart as shown in the screenshot above.  The results are often very compelling - clearly showing how issues at stations have a compounding affect on the overall performance of the line.  With these views you can target the problem areas quickly and work with your team to implement and evaluate corrective actions.  While simple, this metric is very powerful at quickly pinpointing areas to focus improvement efforts.
