Symbols for Flow-Process Chart

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 FPA

Whatdoes thecustomer need?, operations are necessary? Can someoperations be eliminated, combined, or simplified?.

Whois performing the job? Can the operation be redesigned to use less

skill or less labor? Can operations be combined to enrich jobs? .

Whereis each operation conducted? Can layout be improved? .

Whenis each operation performed? Is there excessive delay orstorage? Are some operations creating bottlenecks? ..

Howis the operation done? Can better methods, procedures, orequipment be used? .

Information Flow Analysis

Types of information flow:

Information is the product of operation

Information is used for management control

Symbols used in information flow analysis(Figure 7.9)

Symbols for Information Processing Flow ChartOrigin of record (used to identify an operation that involves the addition

of significant data to a blank form)

Subsequent writing (a step in which significant data is added to an existing

record)

Handling operations (any nonproductive step, such as sorting, stapling, or

folding)

Move (a step in which the record is transported from one person, department,

or work place to another)

Inspection (used when the step involves examination of the quality or

clearness of a record)

Delay, file, and destroy (identifies a point or time at which the record is

inactive

BPR Philosophy

Does the reengineering consultant seethe glass as half full or half empty?

Neither.

Its the wrong size of glass!


16/16

Principles of BPR

Organize around outcomes

Have the people who do the work, process

their own information

Put the decision point where work isperformed and build control into the

process

Eliminate unnecessary steps in theprocess
