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

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
