3 Introduction Principles Practices Patterns Wrap up

4 Challenges in Specifying Business Architecture Most organizations try to capture their business architecture in documents plus disintegrated informal drawings This approach quickly leads to inconsistent and out of date business architecture specification

5 Anti Pattern: Informal Drawings with Non-Standard Notation How to optimize the service time for the VIP customers? 5

6 The Truth is in the Models 6

7 BPMN the Standard for Business Process Modeling ü Business Process Model and Notation (BPMN) is known as de facto standard for graphical business modeling ü For basic modeling about 20 BPMN elements are sufficient ü 1 day of training is enough to learn BPMN basics 7

8 Business Process Modeling: State of the Practice Business process modeling practice is not yet mature Modelers create complex and inconsistent business process diagrams that are not accepted by stakeholders 8

9 What Sometimes Happens in Modeling Practice ~450 Activities ~950 Flows Some facts about the project: ü Model-driven development ü 50 modelers working 4 years ü diagrams 9

10 Business Process Modeling: Advancing State of the Practice + Use modeling standards + Establish a set of principles for efficient modeling + Apply modeling best practices + Reuse business process patterns 10

11 Introduction Principles Practices Patterns Wrap up

12 A Primary Set of Principles for Efficient BPMN 1. Unified Business Process Understanding 2. A Minimal Subset of BPMN Elements 3. Strict Naming Conventions 4. Simple Business Process Diagrams 5. Appropriate Abstraction 12

13 Unified Business Process Understanding Business Process is a reusable set of related activities, which is performed by an organization in order to create business value (product, service, document) leading towards achieving organization s business goals. Can you define... a clear beginning?... a clear end?... the business value process brings? a set of composing activities? a reusable sequence of activities? Examples: ü Provide Loan ü Fulfill Order ü Organize Conference ü Prepare Annual Budget ü Handle Incident Report ü Perform Financial Audit ü Recruit New Employee 13

14 A Minimal Subset of BPMN Elements 14

15 Strict Naming Conventions Language influences thinking ü Participant: a noun, e.g. Delegate, Seminar Coordinator ü Activities: a strong verb + a noun, e.g. Announce Seminar ü Events: a noun, e.g. Registration Request, Registration Deadline ü Data objects: a noun, e.g. Customer List, Feedback Form ü Gateways: unnamed (!) gateways do not perform work ü Sequence Flow: named only after a data-based gateway, gives a condition on which it is activated, e.g. Participants > 30 15

16 Simple Business Process Diagrams Multiple Levels of Detail Rule: up to 10 activities in a single diagram Question: How many tasks can we define in 3 levels of detail? 16

17 Appropriate Abstraction All models are wrong but some are useful. W. Edwards Demming 17

18 Introduction Principles Practices Patterns Wrap up

19 Throwaway Modeling Business processes are modelled for short-term usage Typically for scoping change in business improvement projects A particular aspect is emphasized Automation, data exchange, task durations, waste, etc. Process consistency and completeness is not the main concern ü Apply simplest tools ü Do not forget to throw away the model! 19

20 Sustainable Modeling Business process model is a corporate asset that provides a long-term value and needs to be maintained and evolved ü Strict adherence to the principles is necessary ü A need for a real process modeling tool 20

21 Practices for Sustainable Business Process Modeling 1. Model Ownership Stewardship 2. Collaborative Modeling 3. Model Review 21

22 Model Ownership Stewardship Each business process is assigned to a person, who is responsible for developing and maintaining its model (in collaboration with process stakeholders) ü Gives a clear contact point for process improvements ü Enables business process model sustainability 22

23 Collaborative Modeling Business process modeling is a tool for improving communication and collaboration ü Modeling needs to be performed in teams ü Certain techniques like pair modeling can be applied 23

24 Model Review A quality of model needs to be assessed on a regular basis Review by subject matter experts focuses on the content Review by modeling mentor focuses on the form ü Enables high-quality and sustainable models ü Helps to improve modeling skills 24

25 Introduction Principles Practices Patterns Wrap up

26 Fundamental Business Process Patterns in BPMN 1. Deferred Choice 2. Internal Business Error 3. Interruptible Subprocess 26

27 Pattern #1: Deferred Choice 27

28 Pattern #2: Internal Business Error Handle Offer Request 28

29 Anti Pattern: Repeating Event 29

30 Pattern #3: Interruptible Subprocess 30

31 Some Business Process Blueprints in BPMN 1. Reservation 2. Competition 3. Consolidation 31

32 Blueprint #1: Reservation 32

33 Blueprint #2: Competition Collect Proposals 33

34 Blueprint #3: Consolidation 34

35 Introduction Principles Practices Patterns Wrap up

36 Building Sustainable Business Modeling Culture ü Use business modeling standards like BPMN ü Adhere to the principles for efficient modeling ü Apply best practices for modeling, models usage & management ü Learn and apply business process patterns and blueprints Improving business models is a never ending journey... 36

37 Modeling Culture Center of Excellence Modeling Principles Model Governance Model Usage High Value from Modeling and Models 37
