Business Process Modeling Some Principles of Effective Business Process Modeling
Model With a Purpose
Model in Context
Aim for Simplicity
Be Proficient with Modeling Fundamentals
Embrace Change while building on Invariants

Diagramming Modeling Model with a Purpose If your goal is: Aim to be: Informative Imparting knowledge, Instructing, Interpreting, Enlightening Descriptive Serving to describe or characterize by description, Supports interpretation Prescriptive Giving instructions, Being directive (Flexible guidance vs Strict enforcement) Visualizing Call for actions, Interaction & commitment, Customized view Structuring / Analyzing Structuring the process, Allocating resources, Estimating, Improving, Optimizing Enacting / Automating Monitoring commitment, Assessing progress, Controlling compliance Unique Semantic Uniform Interpretation

Model in Context Modeling in the small Modeling in the large Green Field Modeling Brown Field Modeling Integration Standardization Predefined Architecture Emerging Architecture Operational Strategy Scope Reuse Architecture

Aim for Simplicity
“ It is a simple task to make things complex, but a complex task to make things simple ”
Meyer's law
Adjust Granularity but always be precise
Travel light

Abstraction
The suppression of irrelevant details
(De)composition
Process composites and their components
Separation of Concerns (SoC)
Identify, encapsulate, and manipulate as independently as possible those parts of the process that are relevant to a particular concern.
Separation of Duty (Control) (SoD)
The attribution of authority over process and activities and their evolution
Point of View and Projection
Different depictions (diagrams) of the process or involving the process to provide a more complete picture

Workflow Patterns Control Resources Temporal Data Exceptions Process Model of the process Perspectives of the process

Embrace Change
Evolutionary iterations
Enabling the Next Effort is Your Secondary Goal

Building on invariants
Aim for Invariants
Invariance over Domain (stability)
Invariance over Time (consistency)
Invariance over Persons (consensus)
Invariance over Point of views (modality coherence)

Principles of Effective Process Modeling
Model With a Purpose
Solutionning the current business problem is your Primary Goal
Ensure that you deliver Value to your Stakeholders
Model in Context
Operational Strategy, Process Architecture
Scope, Reuse
Aim for Simplicity
Adjust Granularity but always be precise
Travel Light
Abstraction, (De)composition,
Projections, SoC, SoD
Embrace Change while building on Invariants
Evolutionary iterations
Enabling the Next Effort is Your Secondary Goal
Inspired from S. Ambler “Agile Modeling” and P Kroll an d P. Kruchten “The Rational Unified Process Made Easy”

The Business Process Modeling Notation What is Possible vs What is Useful

Usefully possible and possibly useful
Independent of context
Ease of use (convenience of representation)
Ease of understandability (Simplicity)
Dependent of on context
Your Goal
Expressiveness w.r.t your domain of discourse
The desired granularity
The Point of View of interest

What is possible Control Resources Temporal Data Exceptions Process - Subjective interpretation of the results presented at http://www.workflowpatterns.com/evaluations/standard/index.php And in -Gagné, D .and Trudel, A. ”The Temporal Perspective: Expressing Temporal Constraints and Dependencies in Process Models.” In 2008 BPM & Workflow Handbook. Very Strong Weak Strong Moderate Weak

Visualizing Call for actions, Interaction & commitment, Customized view What is useful If your goal is: Structuring / Analyzing Structuring the process, Estimating, Improving, Allocating resources, Optimizing Enacting / Automating Monitoring commitment, Assessing progress, Controlling compliance Is: Diagramming Modeling Excellent at Visualizing Real Good at structuring Good for analyzing depending or your needs Good for enacting depending on granularity Reasonable for automating
