Chapter 6 Flashcards
Process Flowcharting
Creation of a visual diagram to describe a transformation process
Other names for Process Flowcharting
Flow-process charting
Process mapping
Service blueprinting
Value stream mapping
Process Flowcharting Purpose
To describe a process visually to find ways of improving the current process.
-Find repetitive operations
-Identify bottlenecks
-Describe directions and distances of flows (people, material and information)
-Reduce waste
Keep component of certifications such as ISO 9000
Process Flow Analysis Might Result in Changes to:
Raw materials
Suppliers
Product (output) design
Job design
Processing steps used
Equipment or tools
Management control information
i.e. Anything but customers may be changed!!
Steps in Process Flowchart AnalysisUsing the Systems Approach
- Select a process to study
- Form a team to analyze & improve the system
- Specify the boundaries of the transformation
process - Identify and sequence the operational steps
- Identify the performance metrics
- Draw the flowchart
Operation
a task or work activity
Inspection
an inspection of the product for
quantity or quality
Transportation
a movement of material from
one point to another
Storage
an inventory or storage of materials
awaiting the next operation
Delay
a delay in the sequence of operations
Questions to Ask in Process Flow Analysis
Who What When Where Why How
Who
is performing the job? Can the operation be redesigned to use less skill or less labor? Can operations be combined to enrich jobs?
What
does the customer need?, operations are necessary? Can some operations be eliminated, combined, or simplified?
When
is each operation performed? Is there excessive delay or storage? Are some operations creating bottlenecks?
Where
is each operation conducted? Can layout be improved?
