# Create a Current State Value Stream Map (VSM) – Studypool

I’m studying for my Computer Science class and need an explanation.

In this exercise, you will learn how to create a current state value stream map for CK&N, Inc., a peanut butter and jelly sandwich factory. Based on the Lean Enterprise Institutes philosophy, “Whenever there is a product for a customer, there is a value stream. The challenge lies in seeing it,” CK&N wanted to map their current value stream so that they could make improvements to it as necessary in the future. You and your team are tasked with following the steps below to create the CK&N peanut butter sandwhich process.

Step 1: Calculate takt time in seconds. Don’t proceed until this step is done. Use the following formula to calculate Takt time for your process:

(Available Minutes for Production – Minutes for breaks, meetings, etc./ Required Units of Production)*60 = Takt Time

In our example, we have a daily demand of 700 pieces with the following arrangement.

• Hours per shift: 8
• Break minutes per shift: 30
• Shifts per day: 1
• Days per week: 5

The takt time will tell you how many seconds it will take to produce a completed PB&J sandwhich. Takt Time = _________s.

Step 2: Have a big piece of paper, pencils and erasers ready. You can use software to draw your VSM, however, it is recommended that you always draw the map on paper first. An 11”x17” paper will work best for this exercise.
