Value Stream Mapping and Analysis Due: Sunday, Midnight of Week 3 (10% of course grade)
Overview
As we have learned though our readings and discussions in this course, Lean is used to improve operations
and processes in services, manufacturing, healthcare, government and other sectors of the economy. A core
tool in Lean is Value Stream Mapping. This tool helps us to visualize complex work systems (including
material and information flows) so we can better address disconnects, redundancies, and gaps in how work
gets done between the beginning and end of a process.
The primary type of value stream is one in which a product or service is requested by (and delivered
to) an external customer. Examples include: request to receipt, order to delivery, and quote to cash.
Other value streams support the delivery of value, called value-enabling or support value streams.
Examples include recruiting, onboarding, IT support, and annual budgeting.
Since it is nearly always a mistake to initiate changes without have a clear picture of how the system is
currently functioning, we are beginning our Course Project with the creation and analysis of a Value Stream
Map.
Instructions
For the Assignment, 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.
