Introduction to BPMN

© SAP 2007 /

“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

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

ProcessInnovation

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 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)

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

Optimization and Configuration Rules

Product Configuration, Deal Configuration

SAP NetWeaver Business Rules Management (BRM)

© SAP 2007 /

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 /

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.
