How To Correctly Read The Different Cycle Time Charts: 1. Scatter Plot

The document describes three different types of cycle time charts: 1) Scatter plots show the timeline and cycle time of individual tasks on a graph to indicate probability of completion times. 2) Histograms show the number of tasks completed within different time periods to identify median completion times. 3) Heat maps show the stages of a workflow process and types of tasks to identify bottlenecks.

1. Scatter Plot

- The horizontal axis is a timeline



- The vertical axis represents the cycle time in days

- Each spot on the scatter plot represents a “done” task on a given date

- The horizontal percentile lines indicate what is the probability 



(95%, 85%, 70%) that you finish a task in a given cycle time (or faster)

From this scatter plot we read out there is 95% probability to complete a task in
4 days or less

2. Histogram

- The horizontal axis is the cycle time in days



- The vertical axis is the number of workitems in the period

- The important part of the chart is its tail. The longer the tail,
t the less predictable your estimations will be

From this histogram we read out 50% of the tasks in the


selected period were completed in 1 day

3. Heat Map
- The horizontal axis
inrepresents the stages of
inyour workflow

- The vertical axis shows the
iydifferent task types

- The chart shows you where


yttasks get stuck

- It helps you spot if there is a


ucertain stage of your
uworkflow that is becoming a
ubottleneck

From this heat map we read


out that the “Ready for review”
work stage is a bottleneck for
certain taks types
