What Is Business Analysis?
A clear explanation of the business analysis profession — what it involves, what business analysts do, and why the role exists in almost every industry.
Start Free BA Training →The Simple Explanation
Business analysis is the work of understanding what an organisation actually needs — and making sure that what gets built, changed, or implemented actually solves the right problem.
Every organisation has problems: processes that don’t work, systems that are outdated, opportunities that aren’t being captured, regulations that require compliance. Business analysis is the discipline that identifies these problems clearly, defines what’s needed to address them, and ensures that solutions are built to meet real requirements rather than assumed ones.
The person who does this work is called a business analyst (BA). They sit between the business — the people with the problem — and the delivery team — the people who build or implement the solution. Their job is to translate between these two worlds.
Why Business Analysis Exists
Without business analysis, organisations regularly build the wrong things. A classic pattern: technology teams build exactly what they were asked to build, stakeholders are disappointed with the result, and significant time and money has been wasted. Post-mortem analysis almost always reveals the same root cause — requirements were unclear, incomplete, or never properly validated.
The Standish Group’s CHAOS Report has tracked IT project failure for decades. Requirements-related problems (unclear requirements, scope creep, missing stakeholder input) consistently appear in the top 5 reasons projects fail. Business analysts exist to prevent these failures.
The Business Analyst’s Role in a Project
In a typical project, a business analyst is involved from early requirements gathering through to solution delivery:
| Phase | What the BA Does |
|---|---|
| Initiation | Understands the business problem, identifies stakeholders, scopes the analysis work |
| Discovery | Elicits requirements through interviews, workshops, and document analysis; maps current-state processes |
| Analysis | Documents requirements (user stories, BRD, use cases), identifies gaps, resolves conflicting requirements |
| Design support | Reviews proposed solutions against requirements; validates that the design meets business needs |
| Build/test | Writes and validates acceptance criteria; supports UAT; manages requirement changes |
| Deployment | Supports user training and change management; confirms solution meets original requirements |
What Makes Business Analysis Different from Other Roles
Business Analyst vs Project Manager
The project manager owns the delivery: schedule, budget, resources, risk, and issues. The business analyst owns the requirements: what needs to be built, why, and to what standard. Both are essential on complex projects. On smaller projects, one person sometimes covers both — but they’re genuinely different skill sets.
Business Analyst vs Product Owner
The product owner (in Agile frameworks) sets the product vision and decides what gets built in which order. The business analyst ensures the team understands what to build — providing detailed requirements, acceptance criteria, and stakeholder context. In some teams these roles overlap significantly; in others they’re clearly distinct.
Business Analyst vs Systems Analyst
Business analysts focus primarily on the business problem and the requirements. Systems analysts focus more on the technical solution — how systems need to change. The distinction has blurred as BA work has become more technology-adjacent, and many organisations use the titles interchangeably.
Types of Business Analysis Work
IT/Technology Business Analysis
The most common BA context. BAs work on software projects, system implementations, and digital transformation programmes — translating business requirements into specifications that development teams can build against. This is where Agile BA techniques (user stories, backlog refinement, sprint ceremonies) are most prominent.
Process Improvement
BAs analyse current business processes, identify inefficiencies and pain points, and design improved future-state processes. This work often sits in operations improvement, shared services transformation, or Lean/Six Sigma programmes. See business process improvement guide.
Business Case and Strategy
Senior BAs often support strategic decision-making — developing business cases for investment decisions, analysing options, and presenting recommendations to executives. This work requires financial literacy and the ability to communicate at a senior level.
Regulatory and Compliance
In financial services, healthcare, and government, BAs analyse regulatory requirements and translate them into system and process changes. This work requires domain expertise in the relevant regulatory framework alongside standard BA skills.
The Business Analysis Knowledge Areas
The BABOK (Business Analysis Body of Knowledge) defines six knowledge areas that together describe the full scope of business analysis work:
- Business Analysis Planning and Monitoring — planning how the BA work will be done on a specific project
- Elicitation and Collaboration — gathering requirements and working with stakeholders
- Requirements Life Cycle Management — maintaining requirements throughout the project lifecycle
- Strategy Analysis — understanding the business context and defining the solution approach
- Requirements Analysis and Design Definition — documenting and structuring requirements
- Solution Evaluation — assessing solutions against requirements and business needs
Is Business Analysis the Right Career?
Business analysis is a strong fit for people who:
- Enjoy understanding complex systems and how organisations work
- Are good communicators who can adapt their style for different audiences — executives, developers, end users
- Like facilitating conversations and helping groups reach shared understanding
- Are comfortable with ambiguity — BA work rarely starts with clear answers
- Want a career that’s accessible from a wide range of backgrounds without requiring a technical degree
- Value variety — different projects, different industries, different stakeholder challenges
The career path leads from junior BA through to senior BA, lead BA, and specialised roles (enterprise architect, business analysis manager, strategy analyst). See the business analyst career path guide for full detail on progression and salaries.

What qualifications does a business analyst need?
No specific degree is required. Employers look for demonstrated BA skills (requirements documentation, stakeholder management, process analysis), a certification (CBBA or CBAP), and relevant domain knowledge. Many successful BAs transitioned from operations, finance, healthcare, government, or IT support backgrounds. See the BA certification guide.
What industry does business analysis work in?
Every industry that runs projects employs business analysts — financial services, technology, government, healthcare, retail, resources, utilities, education, and consulting are all major BA employers. The core skills transfer across industries; domain expertise is built on top.
How much does a business analyst earn?
Entry-level BAs in Australia earn AUD $70,000–$95,000; mid-level $95,000–$130,000; senior $130,000–$175,000+. In New Zealand, entry-level starts at NZD $65,000–$85,000. Financial services and consulting pay the most. See the Australia salary guide and NZ salary guide.
