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!

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
