Value Stream Maps

A VSM helps analyze the current release cycle process. The goal is to visually show where a team creates value and where thereโ€™s waste. Armed with this information, a team should aim to create a process that delivers maximum value with minimum waste.

Some values to consider:

  • Process time is how long the team spends on tasks that provide value.
  • Total lead time is how long it takes the team to get that feature to the customer.
  • Activity ratio is the ratio between the process time and the total lead time: ActivityRatio=ProcessTimeTotalLeadTimeActivity Ratio = \frac{Process Time}{ Total Lead Time }
