Which has a higher flow rate? 10 customers arriving over two hours or 10 customers arriving over three hours?

10 customers arriving over two hours

Which of the following is NOT a flow time?

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

How you calculate flow time depends on the _________________ of the process you are analyzing

Scope

You should choose a flow unit based upon upon what you want to _______________ and __________________.

Track & Measure

Triangle

True or False: A flow unit must be a measurable quantity

True

True or False: A process flow diagrams outlines a directional flow in a the process

True

True or false: In a machine-paced line each worker always works at the same rate

True
