What is a business process ? A business process is a collection of activities that takes one or more kinds of input and creates an output that is of value to the customer [Hammer and Champy, 1993] Processes represent the flow of work and information throughout the business [BusinessObjectsModelSpecialInterestsGroup, 1995] 4

What is a business process ? 5 Business Process is a set of steps and/or activities that are correlated and use people, information, and other resources to create value for an internal or external customer of an organization.

Business process complexity is increasing 6

What is a model ? 7 A model is an idealization of an entity or condition, and is asystem of objects, attributes, and relationshipswhich are designed to simulate a given real-world system,under specific situations that are correlated. A model always emphasizes on some systemelements and abrogate or ignore the rest. A modeling tool is more than a drawing tool We use models (modeling tools) to… – Understand a process and – Improve a process

A model depicting a set of processes 8

Modeling a business process 9 For modeling a business process we need a widely accepted method of modeling and a comprehensive and simple diagrammatictechnique, capable to represent a business process, eliminating the complexity and clarifying the important architectural features. Business Process Components : Events, Functions/Actions, Employees/Persons, Data, Products & Services Events trigger functions Functions generate events Data is processed in thefunctions Employees are responsible for functions Employees belong to organizational units Functions create and process products &services

Motivation for Modeling 10 Optimizing organizational changes Building up, saving and archiving business knowledge through reference models Using models for – Process documentation (e.g. ISO 9000 Quality Management) – Process reorganization – Process monitoring & controlling Time & Cost Estimation for given business process Continuous improvement Benchmarking : compare with best practices Workflow management Realization of data processing flows for – software selection (e.g. ERP) or/and – workflow systems adoption

Motivation for Modeling 11 An example: The management of Operational Risk – Operational Risk is the risk of (operational) losses resulting from the failure of people, processes, systems and from external factors. For a long time, operational risk was not even recognized. Lack of segregation of duties [SoD] Lack of supervision Poor control of procedures No senior management involvement System failures …. – Operational risk should be examined through the business processes, that is, the flows of business.

Main Benefits of modeling 12 Introduces rigor & method Provides a single, consistent record Integrates process, systems, organization, information & data Allows viewing and analysis of relations Provides multiple viewpoints Aids validation, walk-through & testing Provides an ideal medium for evaluating “what if?” scenarios Provides a platform for rapid process engineering

Modeling Phases 13 Modeling a business process is itself a business process Analyze - describe AS-IS, SHOULD-BE, TO-BE -requirements definition (καθορισμός απαιτήσεων) Plan & Design - identify & model - core business process components -design specifications (προδιαγραφές σχεδιασμού) Implement - Implement TO-BE - Implementation description (περιγραφή υλοποίησης)

Roles during modeling procedure 14 Business Process Owner and/or Manager – understands models – motivates & encourages his/her implementation team System Analyst – analyzes & creates models Field Expert – validates models

ARIS : a Framework & a Platform Tool 15 ARIS : ARchitecture of Integrated Information Systems developed by Professor August-Wilhelm Scheer, ΄90s creation & optimization of integrated Information Systems description of IS-objects & their relationships to fully describe a business process we need (and use) – components/objects : procedures (processes/functions), events, products/services, organizational units, human resources/employees, information technology resources, raw materials – their relationships & interrelationships

A generic overview of ARIS platform architecture 16 ARIS has a flexible architecture that can scale from a single user to hundreds of users geographical dispersed. The Webbased clients based on Java can be launched in the Web browser via a central link.

ARIS methodology: conceptual views 17 Data View: prerequisites and events, information for customers, persons, products and services Organizational View: structures and relationships between organizational units and persons Function View: functions, sub-functions and their (sequential) relationships Control/Process View : relationships between organization units, functions, data and their link with products and services

Common mistakes 26

Key principles for ARIS-modeling Key principles for ARIS-modeling Stick to the ARIS method Don’t model the universe Know when you have done enough Keep it simple – clever models often confuse Define standards and stick to them Don’t re-invent the wheel; re-use wherever you can If it looks sensible it probably is sensible – if it looks silly it definitely is silly

Benefits of using ARIS benefits of using ARIS Event-driven Process Chain methodology Users’ work allocation Reliable tool High level functionality Customization HTML reports Supports – Hierarchical deconstruction of procedures – Simulation of procedures – Integration of models Provides an easy & descriptive way for Business Process Management
