2. 2  Business processes can be quite complex  Process model: any abstract representation of a process  Process-modeling tools provide a way to describe a business process so that all participants can understand the process  Advantages of process models  Graphical representations are usually easier to understand than written descriptions  Provide a good starting point for analyzing a process  Participants can design and implement improvements  Document the business process  Easier to train employees to support the business process Introduction

3. Flowcharting Process Models 3  Flowchart  Simplest process modeling tool  Graphical representation of a process from beginning to end  Uses a standardized set of symbols  Process mapping  Often used interchangeably with flowcharting  Specifically refers to activities occurring within an existing business process  Develops an “as-is” representation of existing processes, with a goal of exposing weaknesses that need to be addressed

4. Basic Flowcharting Symbols 4

5. Flowchart Design Steps (1)  1. Establish the system boundary. The system boundary is critical in designing a flowchart.  2. Determine column headings. Column headings should focus on areas of responsibility—usually department names, functions, or position titles.  For example, in a “purchase inventory” flowchart, column headings would include requesting departments, purchasing department, accounting department, receiving department, and vendor. 5

6. Flowchart Design Steps (2)  3. List actions performed within each column. In this step, list what each department does within the system. For example, the purchasing department would: (a) receive purchase requisitions from requesting departments; (b) prepare a purchase order; (c) send the original purchase order to the vendor; and (d) send copies of the purchase order to the requesting department, the accounting department, and the receiving department.  4. Select appropriate symbols.  5. Prepare a first draft.  6. Discuss the flowchart with others.  7. Revise as needed. 6

7. Example - Customer Invoice process The Customer Invoice process goes through the following stages:  The administrator starts an invoice by getting a list of items and their prices  The administrator calculates invoice totals from the amount of items  The administrator prints the invoice and takes it to the director for authorization  If the calculations are not OK the director returns the invoice to the administrator for corrections  If the calculations are OK the administrator delivers the invoice to the customer  The administrator checks with the customer for payment  The director confirms if payment was made. If payment was not made the administrator checks again with the customer  After confirmation of payment the administrator closes the invoice 7

9. Evaluating Process Improvement 9  Disrupting the current process to make changes can be costly and time consuming  Dynamic process modeling takes a basic process flowchart and puts it into motion  Uses computer simulation techniques to facilitate the evaluation of proposed process changes  Computer simulation  Uses repeated generation of random variables that interact with a logical model of the process  Predict performance of the actual system

10. ERP Workflow Tools (1) 10  Workflow tools  Software programs that automate the execution of business processes and address all aspects of a process, including:  Process flow (logical steps in the business process)  People involved (the organization)  Effects (the process information)  ERP software provides a workflow management system to  monitor workflow tasks  if the tasks are not completed on time, can automatically take various actions

11. ERP Workflow Tools (2) 11  Workflow provides a number of useful features  Employees can track progress of workflow tasks  System can be programmed to send reminders to employee(s) responsible for a task  Workflow tools are a powerful way to improve process efficiency and effectiveness

12. Draw a flowchart to model a salesperson expense claim process based on the description of the following activities in order:  The salesperson completes a expense claim form after travelling  He makes a copy for his records and attaches receipts for all expenses over SAR100  The salesperson mails the claim form and receipts to the manager at the branch office  Upon receiving the application, the manager checks whether it is complete  If something is not OK with the claim form the manager mails it back to the salesperson asking for explanation, verification, or modification  If the everything is OK, the manager approves report and mails the application to accounts payable officer at the head office  The accounts payable officer at the head office records the application and makes payment 12 In-class Exercise – Expense claim process

13. In-class Exercise - Mail order process The Mail order process goes through the following stages:  The customer fills out order form  The customer submits order form to mail order supplier  The mail order supplier receives order and inspects it  If the information is incomplete, mail order supplier returns form to customer  If the information is complete, supplier ships goods to customer  The customer receives goods and inspects them  If goods are not acceptable, the customer complains to supplier who processes the complaint 13

14. In-class Exercise – Online reservation process  Model an online reservation process based on the description of the following activities in order:  A customer can select “book flight” (a 1 ).  Then he “enters dates” (a 2 ) of reservation.  The system “searches and displays available choices” (a 3 ).  He either goes back to the beginning to make changes, or proceeds by “choosing a choice” (a 4 ).  If he is an existing customer recorded in the system, he should “log in” (a 5 ) to the system, and then he can either “confirm an existing credit card” (a 7 ) recorded in the system, or “enter credit card information” (a 6 ) of a new card.  If he is a new customer, he should “register” (a 8 ) and then “enter credit card information” (a 9 ) of a new card.  Finally, he “places the order” (a 10 ) of reservation. 14
