Select a value stream in your organization that can benefit from analysis and
improvement. As noted previously, the value stream (or end-to-end process) selected does not need to be
overly large or complex. Select something which has the potential for meaningful improvement, but which is
manageable within the scope of this assignment.
1) Develop a current state Value Stream Map of your selected value stream. Show the customer demand
rate (or Takt), information flow, work flow, and summary timeline on the map.
2) Document key metrics for each process block:
Process time (PT)
Lead time (LT)
Percent Complete and Accurate (%C&A)
Include any other appropriate metrics, such as number of operators, changeover time or setup time,
batch size, and % uptime.
3) Calculate the current state summary metrics:
Total lead time (Total LT)
Total process time (Total PT)
Activity Ratio (AR)
Rolled Percent Complete and Accurate (Rolled %C&A)
4) Describe the current state of the value stream and highlight any performance deficiencies and challenges,
such as delays, excessive WIP, bottlenecks, capacity and workload imbalances, rework, poor quality
yields, long lead times, and other operational issues.
Submission Requirements
Your work may be submitted in either Word or PowerPoint.
Since you will need to include a diagram to map the value stream for #1, you should select
whatever software you are most comfortable working with. Value stream process maps can easily
be created in PowerPoint, but are more difficult to execute well in Word. You should consider using
https://www.draw.io/ which is a free web-based tool for drawing flowcharts. Instructions for use are
posted in the Course Documents section in Blackboard. You may also use other software such as
Visio if you prefer, but this is not necessary. Note: If you do use a different mapping software and
experience difficulties uploading it into Blackboard, convert your map to a PDF or JPG and paste it
into Word or PPT before submitting.
For #2, the information for each process block should be on the value stream map.
For #3, it can
be on the map or in tabular form. Show how the summary metrics are calculated. Keep your
written answers brief and to the point. Accuracy is what matters. This should take no more than
one page. There are no additional points for overly elaborate responses.
For #4, a thorough response should take no more than one page.
