Introduction to Modelling for Business Analysis

• Introduction

• Why do you need business analysis models?
• Modelling techniques within A Guide to the Business Analysis Body of Knowledge (BABOK Guide)

• Defining the Scope of Modelling

What is a business model?

• Contrasting scope with levels of detail

Crafting a process to develop a business model

• Applying the steps: elicit, analyse, specify, validate
• Iterating the steps
• OMG modelling standards
• Facilitating requirements workshops
• Correlating models to project type and deliverables

Capturing the multidimensional aspects of an organisation

• Applying the five Ws approach: who, what, where, when, why and how
• Selecting the right level of detail for your stakeholders
• Employing CASE tools and simulations

• Mapping the Business Landscape

Analysing the enterprise

• Exploring the enterprise architecture

Applying business rules

• Documenting the constraints: operative and structural
• Representing business rules with decision tables

• Scoping Business Functions

Initiating the process with functional decomposition

• Determining the functional hierarchies
• Distinguishing between functions, processes, and activities

Drawing UML use case diagrams

• Defining scope and boundary
• Identifying the actors and stakeholders
• Refining the use cases

Documenting business processes

• Selecting the level of detail: brief, casual or fully dressed
• Specifying preconditions and post-conditions

• Modelling Business Processes and Workflows

Leveraging Business Process Model and Notation (BPMN)

• Workflows
• Events
• Activities and tasks
• Sequence flows
• Messages
• Swimlanes
• Tokens

Applying process modelling techniques

• Sequencing and classifying activities
• Categorising events

Refining business process diagrams

• Choosing the right gateways: branches, forks and joins
• Mapping the processes to lanes and pools
• Supplementing the model with data and artifacts: groups and annotations

• Analysing the Enterprise Structure

Establishing the business domain

• Documenting the workers and organisation units
• Using data modelling to analyse business objects

Structuring the enterprise with UML class diagrams

• Constructing associations between the classes
• Packaging for subject areas and organisation units
• Capturing business object attributes

• Finalising the Business Model

Achieving complete coverage with matrices

• Applying the Responsibility Assignment matrix (RACI)
• Prioritising features
• Cross-referencing requirements

Contextualising the model with perspectives

• Documenting business interfaces
• Motivational Mapping from means to ends
• Capturing event timing parameters
• Modelling states with the UML State Machine Diagram
• Specifying supplementary & quality of service requirements

• Communicating the Model to Key Stakeholders

• Choosing the right models for your audience
• Transforming business requirements into user requirements
• Delivering and presenting your models
