BABOK Guide Fundamentals

BABOK® Guide = Business Analysis Body of Knowledge
Current version (as of 2026): v3 (released 2015) + ongoing extensions & practice guides

Published by IIBA® (International Institute of Business Analysis)

What is the BABOK Guide?

• Not a methodology — a framework of best practices
• Describes what business analysis is and how it is performed
• Globally accepted standard for the profession
• Basis for CBAP®, CCBA®, ECBA™, and other IIBA certifications

The 6 Knowledge Areas (KAs)

These are the core domains of business analysis work:

1. Business Analysis Planning and Monitoring
   → Plan how business analysis will be done

2. Elicitation and Collaboration
   → Obtain information from stakeholders & manage collaboration

3. Requirements Life Cycle Management
   → Trace, maintain, prioritize, approve, reuse requirements

4. Strategy Analysis
   → Understand why change is needed (current → future state)

5. Requirements Analysis and Design Definition
   → Structure, refine, specify, model, verify & validate requirements

6. Solution Evaluation
   → Assess value delivered by a solution

The 3 Main Layers of BABOK

BABOK organizes business analysis into three interconnected layers:

1. Business Analysis Core Concept Model (BACCM)
   → the 6 fundamental concepts that are always present

2. Knowledge Areas (6)
   → the main areas of work business analysts perform

3. Techniques (50+) + Perspectives (4–8)
   → the tools and contextual viewpoints used to carry out the work

The Business Analysis Core Concept Model (BACCM)

The six core concepts:

• Change – Controlled transformation
(What are we changing?)

• Need – Problem or opportunity to be addressed
(Why do we need to change?)

• Solution – Specific way to satisfy the need
(How will we satisfy the need?)

• Stakeholder – Someone with interest or influence
(Who cares about this change?)

• Value – Worth, importance, usefulness to stakeholders
(What benefit will be realized?)

• Context – Part of the environment that influences / is influenced
(What surrounds the change?)

6 concepts that appear in every BA activity:

Concept	Short Definition	Key Question
Change	Controlled transformation	What are we changing?
Need	Problem or opportunity to be addressed	Why do we need to change?
Solution	Specific way to satisfy the need	How will we satisfy the need?
Stakeholder	Someone with interest or influence	Who cares about this change?
Value	Worth, importance, usefulness to stakeholders	What benefit will be realized?
Context	Part of the environment that influences / is influenced	What surrounds the change?

Tip: If you understand how these 6 concepts relate in your initiative → you understand the essence of business analysis.

Perspectives (Context Views)

Help tailor the approach depending on the type of initiative:

• Agile
• Business Intelligence & Analytics
• Information Technology
• Business Architecture
• Business Process Management

(Additional perspectives are available in separate IIBA practice guides)

Most Commonly Used Techniques (Top 15–20)

• Interviews / Workshops / Surveys / Questionnaires
• User Stories / Use Cases / Process Modeling (BPMN)
• Data Modeling (ERD, Class diagrams)
• Brainstorming / Root Cause Analysis
• SWOT Analysis / Gap Analysis
• Prioritization (MoSCoW, Kano, Weighted Ranking)
• Traceability Matrix
• Prototyping / Wireframes / Storyboarding
• Document Analysis / Observation
• Acceptance & Evaluation Criteria

Practical Advice for Using BABOK

• Do not try to read it like a novel
• Use it as a reference
• Start with the Knowledge Area that matches your current project phase
• Focus first on:
  → BACCM
  → Knowledge Area 5 (Requirements Analysis & Design Definition)
  → Elicitation & Collaboration
  → Requirements Life Cycle Management
