Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc 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)

Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc Questions to Ask in FPA What does the customer need?, operations are necessary? Can some operations be eliminated, combined, or simplified?…. Who is performing the job? Can the operation be redesigned to use less skill or less labor? Can operations be combined to enrich jobs? …. Where is each operation conducted? Can layout be improved? …. When is each operation performed? Is there excessive delay or storage? Are some operations creating bottlenecks? ….. How is the operation done? Can better methods, procedures, or equipment be used? ….

Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc 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)

Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc Symbols for Information Processing Flow Chart Origin 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

Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc Business Process Reengineering (BPR) BPR defined (Hammer and Champy) BPR Philosophy Principles of BPR

Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc Service Blue Printing Definition Example of SBP (Figure 7.10) SBP and “moments of truth” Ask the same questions as in PFA (what, who, where, when, and how)

Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc BPR Philosophy Does the reengineering consultant see the glass as half full or half empty? Neither. Does the reengineering consultant see the glass as half full or half empty? Neither. It’s the wrong size of glass! It’s the wrong size of glass!

Irwin/McGraw-Hill  The McGraw-Hill Companies, Inc Principles of BPR Organize around outcomes Have the people who do the work, process their own information Put the decision point where work is performed and build control into the process Eliminate unnecessary steps in the process
