Value Stream Capacity Exercise

Step 1. Calculate the Total Available Employee Time (#employees x #days x Labor Hrs per shift) x 3,600 seconds Step 2. Calculate the Employee Productive Time (Qty per Month – (Qty x (scrap + rework rate))) x Cycle Time x Crew Size) Step 3. Calculate the Employee Productive Capacity Percentage. (Employee Productive Time / Total Available Time) Step 4. Calculate the change-over time, scrap & rework time, downtime, inspection time. C/O = (quantity/batch size) x Change-over time Scrap/rework = Qty x (scrap + rework rate) x Cycle Time x Crew size D/T = Downtime% x Total Available Time Inspection= (Inspect% x Quantity) x Inspection time Step 5. Calculate the Total Non-Productive Time Step 4 plus 5S & meetings Step 6. Calculate the Employee Non-Productive Capacity Percentage Total Non-Prod Time / Total Available Time Step 7. Calculate the Employee Available Capacity Percentage. 100% - (Prod. Capacity + Non-Prod Capacity) Calculate the Employee Capacity for this small value stream. 1 2 3 4 5 6 7

Calculate the Inventory Value Using the Days of Conversion Cost Method This method is used when the company tracks inventory but maintains inventory value for the,material content only. The conversion cost is then applied based upon the number of days of material. 1.Calculate the number of days of inventory. (Days in the month * Inventory value / Monthly Material Cost) 2.Calculate the Conversion Cost Applied. (Number of days of inventory * total conversion cost / Number of Days in the Month) 3.Calculate total inventory cost.

Exercise: Defining Value Streams In your group discuss the possible ways in which you might define the Value Streams for the Universal Valve Company. What are the advantages and disadvantages of each ? State your preferred selection with reasons. Remember: Order Fulfillment Value Streams are primarily defined by materials flow.

© BMA Inc. 2009. All rights reserved. Exercise: Define Value Streams Order fulfillment value streams are primarily set up based upon the flow of materials through the process. We need to create a value stream team that includes both production people and the people that support production. The value stream must be a reasonable size. –No less than 10% of revenues –Between 20-150 people.

Example 1: Special Order with Available Capacity We received a special order of 1000 units per month of a Alloy Medium value –Price = \$14.00 per unit –Standard Cost = \$15 –Margin = (\$1) –Material unit cost - \$9.50 We have capacity available to produce these additional products Should we take the order?

Example 2: Special Order without Available Capacity We have received a special order of 1000 units per month –Price = \$14.00 per unit –Standard Cost = \$15 –Margin = (\$1) Material unit cost - \$9.50 Must add an extra person (\$4,204 per month) to the value stream Should we take the order?

© BMA Inc. 2009. All rights reserved. Example 3: Special Order with Outsourced Supplier We have received a special order of 1000 units per month –Price = \$14.00 per unit –Standard Cost = \$15 –Margin (\$1) We have no available capacity, but have found a local supplier –Outsourced purchase cost - \$12.75 Should we outsource this and take the order?

Example 4: Bring Outsourced Processes in House In the Brass Valves value stream continuous improvement has created enough capacity to possibly bring outsourced work in house. –Monthly outsourced cost - \$ 62,400 –Material cost (if we make it in-house)= \$36,000 To produce in house we must: –buy a 2 machines (\$3060 per month) –hire an extra supervisor (\$4500/mo) –and 2 more operators (\$8,400 per month) Should we bring this work in-house?
