Introduction to BPMN
© SAP 2007 / Page 6
“The primary goal of BPMN is to provide a notation that is readily understandable by all business users, from the business analysts that create the initial drafts of the processes, to the technical developers responsible for implementing the technology that will perform those processes, and finally, to the business people who will manage and monitor those processes. Thus, BPMN creates a standardized bridge for the gap between the business process design and process implementation.”
OMG, BPMN 1.1 Specification
!
First published in 2002
Official standard of the Object Management Group (OMG) since 2006
Current Version: BPMN 1.1

Business Process Modeling Notation –Sequence Flow Overview
Activity
Gateway
Event
Activity:A step in the processRepresents work or action performed
Gateway:Controlles flow branching, merging and parallel actions Pure logic – does not do the decision itself
Event:A signal that „something has happened“ Can start, pause and resume or interrupt and redirect
a process or activity
ProcessInnovation

Business Process Modeling Notation -Activities
HumanActivity
AutomatedActivity
Sub-Process
Human Activity:Activity that has to be processed by a natural Person
Automated Activity:Activity that is processed by a system
Sub-Process:A compound (decomposable) Activity that holds a sub-
process modeled with BPMN – can be shown collapsed or expanded

Business Process Modeling Notation -Gateways
Exclusive Choice:Only one path can be takenEach Gate has a boolean data expression
Parallel Split (also AND gateway):Splits sequence flow in parallel stream
Event based Choice:Only one path can be takenDecision is based on events, not data condition
Uncontrolled Merge:Merge exclusive alternative incoming sequence flows
to one outgoing sequence flow
Parallel Join:Merge parallel alternative incoming sequence flows to
one outgoing sequence flow

Business Process Modeling Notation –Events
Start Event:Creates new process instance or indicates start of a sub-process
Intermediate Timer Event:pause the sequence flow of a process or a sub-process
for/until a specific time
Intermediate Message Event:Wait for and receive a message
Intermediate Error:Aborts activity on error
End Event:Ends a sequence flow in a process or a sub-process
Termination:Stop the process or sub-process immediately

Business Process Modeling Notation -Orchestration and Choreography
Pool:A Pool contains a single „BPMN- Process“A sequence flow is constrained in exactly one poolA Process diagramm may contain several poolsDifferentiation between „active“ and „inactive“ (descriptive) poolsOnly one active pool per modelA pool generally represents a logical collection of roles,
organizational units and systems
Lane:A pool may be divided into lanesA lane generally represents a role or an organizational unit
Orchestration:Modeling a process flow of control in a single
internal (active) poolRepresentation as sequence flow
Choreography:Modeling interaction between pools (not flow of
control!)Representation as message flow

Investment Approval Process

Investment Approval Process in BPMN:
Two Pools:one internal (active) pool (own company)one external (inactive) pool (supplier)
Four Lanes within internal pool:one lane for purchase requester roleone lane for external IT equipment prov.one lane for purchase approver roleone lane for purchasing system
Five Human Activities:enter requirements (Requester)derive product from requirements (IT eq.
prov.)review purchase request (Approver)review Approver‘s decision (Requester)view PO confirmation (Requester)
Two data inductive (automated) Activitiescreate purchase ordersave change history

Business Rules Overview
© SAP 2007 / Page 18
What are business rules?Business rules represent the policies, guidelines that drive operational business decisionsBusiness rules are owned by Business, not by IT
Common Kinds of Business Rules: Validation Rules Claim Validation, Loan Application Validation
Rate Calculation Rules Computation of Taxes, Interest Rates, Sales Commissions, Premiums, Bonuses, Duties
Decision Rules Is Applicant Eligible for a Loan ProductCan this good be cleared by Customs?
Recommendation Rules Marketing Promotions, Medical Recommendations, Online Product Chooser
Personalization Rules Website Personalization, Product Personalization , Relationship Personalization
Internationalization and Localization Rules
International Products e.g. Maintaining similar Insurance products across countriesCross border Custom Duties
Exceptions and Special Rules Exceptions, Special Accounts , Special Arrangements, etc.
Optimization and Configuration Rules
Product Configuration, Deal Configuration

SAP NetWeaver Business Rules Management (BRM)
© SAP 2007 / Page 19
Why Business Rules Management?Management and monitoring of rules is a critical component of BPM Externalize business rules from application code Encapsulate rules as re-usable services Increases flexibility, efficiency and control Serving business and IT
Why NetWeaver BRM?Robust tool for central business rules managementIntegrated path from process to rulePerfect fit into SAP NetWeaverComposition EnvironmentEclipse based rule composition
Many Ways to Model RulesModel Rules in the Context of a Business Process using the Process ComposerModel rules as an independent rules project using the Rules Composer
Many Ways to IntegrateUse Rules through an Automated ActivityModel Functions driven by Business RulesUse rules based mapping transformations in a processUse rules based functions for Gateway decisions

Investment Approval Process:Rule: Necessity for Approval
© SAP 2007 / Page 20
Requirement: Automated decision if an approval for the purchase order is needed or not based on the amount of the order and the country of the requestor
Rule Logic:1.: Check the country of the requestor
2.: Based on the country of the requestor:Check if the order amount is below or above a country specific max. value
if it is below: Return „false“if it is above: Return „true“
This rule is a company wide defined business rule that should be used for EVERY purchase order in every possible scenario.Therefore this rule should not be a direct part of this specific process. Instead it should be exposed as a reusable component.
