What is workflow?
What is business process management?
Common workflow and process problems

The role of enterprise systems
Introduction to SAP R3
What is Workflow (1)?



Workflow is a depiction (model) of a
sequence of connected steps
Many see workflow as an abstraction of
actual work
Examples:



The route you take to work
The exact steps to make a Twinkie
The steps to procure raw materials for
manufacturing
What is Workflow? (2)

We model workflow in terms of




what steps are performed
who performs those steps
what dependencies (relationships) exist between
those steps
what external resources (information, materials,
etc.) are required to complete the set of steps
Modeling Workflow

We have tools to model workflow and
implement workflow-based software systems




BizAgi models business processes
UML and UML tools (Visio) model workflow and
various types of processes
There are several tools and there are different
models too
We will use BizAgi in this course and a bit of
Visio
Modeling Workflow (BPMN)

The Business Process Modeling Notation
(BPMN) is used to depict business processes

There are formal symbols to depict the actors in
the process, the tasks performed, and the
relationships between those tasks
A First Workflow Diagram
Modeling Workflow (Visio)

Visio supports several modeling tools for
workflow


Data Flow diagrams model the flow of data
through an information system
UML diagrams model process state, sequence,
and structure
What is Business Process
Management?

I like this definition:


Workflow is concerned with the applicationspecific sequencing of activities via predefined
instruction sets, involving either or both
automated procedures (software-based) and
manual activities (people work)
BPM is concerned with the definition, execution
and management of business processes defined
independently of any single application
Non-normative Definitions?


But let’s not get bogged down in formal
definitions
I can find several definition of the following
terms:



Workflow
Business Process
Business Process Management
Common Workflow
and Process Problems

Lack of workflow integration across functional
units


This leads to a silo effect
Workflow that is not well understood
The Functional
Organizational Structure








Purchasing
Production
Warehouse / distribution
Sales and marketing
Finance and accounting
Human resources
Information systems
Research and development
The Role of Enterprise
Systems

Enterprise Systems (Enterprise Planning
Systems) ERPs


Use best practices to implement cross-functional
workflow systems for various industries
We try to



Eliminate information silos
Create a real-time or near real-time view of an
organization
Establish strong internal controls over data

who can access it and who can change it

There are also open source solutions
Introduction to SAP


SAP R3 (System Analysis and Program
Development) is a client-server application
made up of core business modules and
optional add-on modules
A central relational database sits behind the
server ( SAP HANA, Oracle, SQL Server, …)

SAP – Architecture (1)

Client/Server Environment

Client – hardware/software environment that can
make a request for services for a central
repository of resources


This is the NetWeaver program that you see
Server – hardware/software combination that can
provide services to a group of clients in a
controlled environment

This is the back-end server that you connect to
through NetWeaver
SAP Architecture (2)

Three-Tier Architecture
 GUI
 Graphical User Interface (NetWeaver) or Web
Interface (WebDynpro)
 Application Server
 One or more, help distribute work load
 Database Server
 One single data repository
SAP ERP Components



And get used to all of these codes!
Core
 Financials (FI) (“Track”)
 Materials Management (MM) (“Buy Materials”)
 Sales and Distribution (SD) (“Sell Goods”)
 Production Planning (PP) (“Make goods)
 Human Resources (HCM)
Add-on
 Customer Relationship Management (CRM)
 Supply Chain Management (CRM)
SAP Database



It’s huge (over 25000 tables)
There is little or no data redundancy
Terminology and data definitions are
consistent and accurate throughout the
database

SAP Configuration vs.
Customization



SAP is configured by editing various
configuration tables
Configuration does not require software code
changes
Customization is possible through a
programming language called Advanced
Business Application Programming (ABAP)

Customization is a contested practice
