Operations Management Project Part A: Value Stream Mapping and Analysis
Due: Sunday, midnight of Week 3 (20% of course grade)
Overview
A core tool in Operational Excellence is Value Stream Mapping. This tool helps stakeholders visualize
complex work systems (including material and information flows) and address disconnects, redundancies,
and gaps in how work gets done between the beginning and end of a value stream or end-to-end 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 tocash.
• Other value streams which support the delivery of value are 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 this 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)
• 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 andchallenges,
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 selectwhatever
software you are most comfortable working with. The Value Stream Map can easily be created in
PowerPoint (see the symbols and template provided by the instructor), or neatly drawn by hand.
You may also use software such as Visio. In all cases, please scan or 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 with specifics should take no more than one page. As you discuss
improvement opportunities, mention and make specific reference to the Value Stream Map, including
names of process blocks and performance metrics.
