What is a process?
|
Process: Is any part of an organization
that takes inputs and transforms them into outputs. |
|
What is process analysis and why is it important?
|
Process Analysis helps a company
understand how its processes work Ensures its competitiveness A process that does not match the needs of the firm will punish the firm every minute that the firm operates |
|
What is process flow-charting, what are its basic elements, and what is it ideal for?
|
Process flowcharting is the use of a
diagram to represent the major elements of a process. The basic elements can include tasks or operations, flows of materials or customers, decision points, and storage areas or queues. It is an ideal methodology by which to begin analyzing a process. |
|
What are the flowchart symbols and what do they represent? name an example for each.
|
Square = tasks or operations
eg// giving admission ticket to customer, installing an engine into a car diamond = decision points eg/ how much should be given to customer, which wrench should be used upside down triangle: storage areas / queues eg// sheds, lines of people waiting arrow: flows or materials or customers eg// customers moving to a seat, mechanic getting a tool |
|
what's the difference between a single stage process and a multi-stage process?
|
single stage- one process
multi-stage - multiple processes |
|
what is a buffer? what symbol is usually used for a buffer?
|
A buffer refers to a storage area between
stages where the output of a stage is placed prior to being used in a downstream stage symbol: upside down triangle |
|
What is blocking?
|
Blocking occurs when the activities in a stage
must stop because there is no place to deposit the item just completed If there is no room for an employee to place a unit of work down, the employee will hold on to it not able to continue working on the next unit |
|
What is starving?
|
Starving occurs when the activities in a stage
must stop because there is no work If an employee is waiting at a work station and no work is coming to the employee to process, the employee will remain idle until the next unit of work comes |
|
When does a bottleneck occur?
|
Bottleneck occurs when the limited
capacity of a process causes work to pile up or become unevenly distributed in the flow of a process If an employee works too slow in a multi-stage process, work will begin to pile up in front of that employee. In this case the employee represents the limited capacity causing the bottleneck |
|
What is pacing?
|
Pacing refers to the fixed timing of the
movement of items through the process |
|
What is operation time and its equation?
|
Operation Time = Setup Time + Run Time
Setup Time: time required to prepare a machine to make a particular item Run Time: time required to produce a batch of parts |
|
what is cycle time?
|
Cycle Time = Average time between
completions of successive units |
|
what is throughput time
|
Throughput Time = Average time for a
unit to move through the system |
|
What is the equation for throughput rate?
|
throughput time = 1/cycle time
|
|
what is the equation for efficiency?
|
efficiency = actual output/standard output
|
|
what is the equation for productivity?
|
productivity = output/input
|
|
what is the equation for "utilization"?
|
utilization = time activated / time available
|
