20 customer per hour 30 Eggs
Process scope defines the set of _______________ included in the process
Activities
Which metric is most difficult to calculate directly?
Average Inventory
Dividing the total number of customers that arrived during a period of time by the length of that period of time.
Average flow rate
Understanding the location of the __________________ is critical for improving a process
Bottleneck
Flow units waiting in the process without being worked on are often referred to as ____________________ inventory.
Buffer
An appropriate unit for throughput is _______________.
Burger/second customers/minute
For a process that is ___________________ constrained the bottleneck resource will have 100% utilization
Capacity
If process capacity is 60 units per hour and customers desire 80 units per our then the process is __________________ constrained
Capacity
Process _______________ determines to maximum flow rate a process can provide per unit of time
Capacity
The maximum number of flow units that can flow through that resource per unit of time
Capacity
The case in which demand exceeds supply and the flow rate is equal to process capacity
Capacity-Constrained
An organization that wants to fulfill customer orders more quickly should make the cycle time of there fulfillment process ___________________.
Decrease
From Little's Law we see that if cycle time increases while flow time stayed the same then inventory must ______________.
Decrease
If the cycle time for a process goes down then the time to finish X units starting with empty inventory buffers will _________________.
Decrease
If the flow time (cycle time) for a process goes down then the time to finish X units starting with empty inventory buffers will _________________.
Decrease
If processing time increases, then the capacity at resource with a single employee ___________.
Decreases
A process flow diagram is a graphical way to ____________ the process
Decribe
If the utilization of the bottleneck is less than 100% then the process is _______________ constrained
Demand
Inventory is a mismatch between supply and _________________
Demand
When the flow rate is less than the capacity the process is referred to as _________________ constrained.
Demand
The number of flow units that customers want per unit of time
Demand Rate
Fill in the blank: A process flow diagram is used to ______________ a process.
Describe (graphical representation)
True or False: If the capacity at a resource with multiple employees went up then the processing time definitely decreased
False
True or False: Process analysis is only applicable to manufacturing settings
False
True or False: Some processes do not require inputs.
False
True or False: The utilization of a non-bottleneck resource can be greater than that of the bottleneck
False
True or false: A process that is demand contained can be utilization of 100%
False
True or false: In a worker-paced line each worker always works at the same rate
False
True or false: Inventory can be calculated by dividing the total number of customers that arrived during a period of time by the length of that period of time
False
True or false: The bottleneck is the resource with the fewest number of employees
False
True or false: You should measure the inputs to a restaurant process in customers and the outputs in dollars
False
Inventory is the number ____________ units within the process
Flow
If a university president wanted to know how many students graduated from their university each year, which process metric would he/she need?
Flow rate
A manager of a car wash wants to know how long his/her facility takes to wash a car. what process metric does he/she need?
Flow time
The more patients that arrive in a ten-hour span the _________ the flow rate.
Higher
What are the 2 key questions the manager of a process should ask?
How can we make the process better? Is the process performing well?
Think of a restaurant as a process. Which would be a combination of inputs and outputs for such a process?
Hungry customers become satisfied customers Ingredients becomes meals investments by the owner(s) of the restaurant become revenues
If the sales department can increase the number of customers that request a product per day (i.e. the Flow rate) and the time needed to make that product stays the same, what does Little's law predict will happen to inventory?
Increase
If an accountant wanted to know how much money is typically tied up in a process, which process metric would he/she need?
Inventory
Little's Law states that _______________ = Flow rate x Flow time
Inventory
Imagine a capacity contained, single resource process with multiple employees working at the single resource. If the number of employees increases then what will happen to the cycle time for the process?
It will decrease
If cycle time stays constant but inventory goes down what will happen to lead time?
It will go down
If inventory goes up but flow time stays constant what will happen to cycle time?
It will go down
If cycle time goes up what will happen to lead time?
It will go up
The longer the average flow time, the ______________ the average inventory level
Larger
Flow rate can be _________________ process capacity
Less than Eqaul to
The earlier the patient arrives the same departure time the ___________ the flow time.
Longer
The more stations in a process, the ____________ the time the first flow unit needs to flow throughout the system when it is empty
Longer
An appropriate unit for cycle time is _____________.
Minutes/burger Minutes/customer
A process metric is something that we can measure that informs us about the _______________ and capability of a process
Performance
The __________________ time of a resource is how long that particular resource takes to complete one flow unit
Processing
________________ are shown as a rectangular boxes in the process flow diagram
Resources
___________________ help the flow units to move from being a unit of input to becoming a unit of output.
Resources
Process analysis is a _________________ framework for understanding the detailed operations of a business
Rigorous
