1. Given that VA time = 20 hours and NVA time = 25 hours, what is the estimate cycle time?

20 hours+ 25 hours = 35 hours

2. Given that VA time = 20 hours and NVA time = 25 hours, what is the process cycle efficiency?

20 hours/ 35 hours= 0.57= 57%

Use this information about the observed process of serving customers at a hot dog stand to answer the remaining questions.

Sasha and Andy have opened a hot dog stand at their local park. They offer a hot dog with choice of fresh fruit and beverage to walk up customers between 10 AM and 2 PM. Customers put on their own condiments. Customers say their hot dogs are good, but the wait is a little long.

After two weeks, they have a brisk and growing business. Andy and Sasha notice they are barely keeping up with the customer demand, and making a little money after buying their supplies at the end of each day. They would like to improve their process to meet growing customer demand. A friend was taking a process improvement class and offered to observe them for a few days and help them with a process analysis. These are the process steps obtained after observations spanning a few days.

Process step	Activity	Average time per order(seconds)
1	Sasha takes orders, collects the money, and chats with the walk up customers. Tacks onto order-in board.	60 sec
2	Order on order-in board	30 sec
3	If needed, Andy adds more dogs to the grill and waits for all to be cooked.	20 sec
4	Andy puts cooked dogs in bun, wraps it in foil, adds fruit of choice, & puts in serving container.	40 sec
5	Order sits on counter for Sasha	30 sec
6	Sasha adds beverage	10 sec
7	Sasha calls customer to stand, delivers order and chats a bit	30 sec
8	Andy checks work area, cleans and stocks as needed	48 sec
9	Sasha fills up condiments, keeps serving counter clean, and bags hour trash	48 sec

3. What is the average cycle time per order?

4. Steps 2 and 5 are wait times. How much of the remaining time do you think is NVA time? There is no single correct answeridentify types of waste and estimate the amount of time spent on non-value-added activities. Describe the type of waste and amount of NVA.

5. Using the information from questions 3 and 4, calculate the process cycle efficiency.

6. The hot dog stand is open 4 hours a day (240 minutes). If Sasha and Andy have 50 customer orders in a day, what is the takt time? What is the takt time for 75 customer orders in a day?
