Business analysis helps an organization understand a need, choose a response, and determine whether that response delivers value. It is not just writing down requirements. The BABOK Guide organizes the work into six knowledge areas, from planning and understanding the need through evaluating a solution. They are a useful map, not a mandatory one-way sequence: teams often revisit earlier decisions as they learn more.
What business analysis is—and what the stages are for
The International Institute of Business Analysis (IIBA) defines business analysis as “the practice of enabling change in an organizational context, by defining needs and recommending solutions that deliver value to stakeholders.” The focus is therefore on the change and its value, not on producing documents for their own sake. See IIBA’s definition of business analysis.
The six knowledge areas below come from IIBA’s Business Analysis Standard and BABOK Guide. They describe the work analysts need to consider, but not a fixed sequence every project must follow. A discovery may reveal that the original problem was framed incorrectly; a proposed design may expose a new risk. In those cases, the team should return to the relevant earlier work rather than press on simply because a step was marked complete. IIBA’s Business Analysis Standard and BABOK Guide overview provide the underlying framework.
1. Plan the business analysis work
First agree how the analysis will be carried out. The approach should fit the change: its scale, uncertainty, stakeholders, constraints, and decision-making environment. Planning is not simply scheduling interviews. It establishes how the team will gather and manage information and how decisions will be made.
#1 Best Overall
- Set the approach: Decide which analysis activities are needed, how they will be performed, and how much detail is appropriate.
- Identify stakeholders and plan engagement: Include people affected by the change and those who can provide information, make decisions, or influence implementation.
- Agree governance: Clarify who reviews, approves, prioritizes, or resolves disagreements about analysis outputs.
- Plan information management: Decide how requirements, designs, decisions, and related materials will be organized and kept current.
- Adapt as the work proceeds: Review whether the approach is helping the team make sound decisions, and adjust it when conditions change.
The result is a workable analysis plan, not a guarantee that discovery will unfold exactly as scheduled. IIBA includes planning the business analysis approach, stakeholder engagement, governance, information management, and performance improvement in this knowledge area.
2. Understand the strategy, current state, and need
Before recommending a solution, establish why change is being considered. The analyst helps connect the business problem or opportunity to the outcomes the organization wants, then examines the gap between the current and desired states.
- Describe the current state: Understand relevant processes, capabilities, policies, systems, and constraints. Distinguish observed conditions from assumptions about their causes.
- Define the desired future state: Describe what should be different and what outcomes would indicate progress.
- Assess risks: Consider what could prevent the change from working, including risks created by the change itself.
- Shape a change strategy: Identify a viable route from the current state toward the future state, taking account of constraints and expected value.
This work guards against jumping to a favored product or feature before the underlying need is understood. A proposed solution should be judged against the problem, opportunity, and desired outcomes—not treated as the goal by default.
3. Elicit information and collaborate with stakeholders
Elicitation is broader than asking stakeholders to list what they want. IIBA’s task framework covers preparing for elicitation, conducting it, confirming what was learned, communicating analysis information, and managing stakeholder collaboration. See IIBA’s elicitation and collaboration overview.

Choose methods that fit the question
Interviews can help explore an individual’s experience; workshops can surface differences and build shared understanding; observation can reveal how work happens in practice; and document review can expose existing rules, commitments, or constraints. These are examples, not a ranked list. The right method depends on the people involved, the information needed, and the context.
Confirm and share what was learned
After gathering information, check that it has been understood accurately. For example, a stakeholder may describe a desired feature when the underlying concern is a delay or control weakness. Confirmation helps distinguish the need from a proposed answer. Communicating the findings gives stakeholders a chance to correct misunderstandings, while ongoing collaboration helps the team resolve conflicting perspectives and keep decisions connected to the people affected.

4. Analyze and define requirements and designs
Raw information becomes useful when it is organized, clarified, checked against the need, and translated into requirements or design options. Requirements should be clear enough for the people who need to use them, but detailed at a level appropriate to the initiative. IIBA describes requirements analysis and design definition as including specification, verification, validation, architecture, design options, and value assessment; see its requirements analysis and design definition overview.
Keep the four requirement types distinct
| Type | What it expresses | Example of its role |
|---|---|---|
| Business requirements | Organizational goals, objectives, and outcomes. | State what the change is intended to achieve. |
| Stakeholder requirements | Needs of particular stakeholders. | Describe what a user, operator, or decision-maker needs from the change. |
| Solution requirements | Capabilities and qualities of the solution, including functional and non-functional requirements. | Specify what the solution must do and relevant qualities it must have. |
| Transition requirements | Temporary capabilities needed to move from the current state to the future state. | Cover matters such as data conversion, training, or continuity during transition. |
These categories answer different questions. Treating them as one undifferentiated feature list can obscure whether an item describes a business outcome, a stakeholder need, a solution capability, or a temporary migration need. IIBA explains the categories and traceability in its requirements classification schema.

Verification asks whether a requirement or design is expressed clearly and consistently. Validation asks whether it addresses the need. The analyst also considers relationships among requirements, possible solution designs, and the value and trade-offs of available options. A solution can satisfy a written requirement yet still fail to address the underlying need if that requirement was based on a mistaken assumption.
5. Manage requirements and designs through their life cycle
Requirements and designs can change as stakeholders learn, constraints shift, or solution options develop. Life-cycle management keeps them useful and controlled instead of letting outdated or conflicting versions accumulate.
- Maintain and prioritize: Keep analysis information current and order work according to value, urgency, dependencies, and constraints.
- Assess proposed changes: Consider effects on the need, other requirements, designs, plans, and decisions before accepting a change.
- Use appropriate approval: Follow the initiative’s governance for review and approval rather than assuming every team uses the same sign-off process.
- Preserve traceability: Link needs, requirements, designs, and solution components so the team can explain why an item exists and what it supports.
Traceability also works in the other direction: it can show whether a solution component has a supporting need and whether a change may affect related items. This helps identify missing requirements, unsupported solution elements, and downstream impacts when a decision changes.

Once a solution is available, delivery alone does not prove that the intended benefit has been achieved. Evaluation examines how the solution performs, analyzes relevant measures, identifies limitations in the solution or the wider enterprise, and recommends actions that could increase value. IIBA outlines this work in its solution evaluation overview.

Evaluation connects the outcome back to the need and desired future state. If performance falls short, the cause may lie in the solution, its implementation, the surrounding organization, or an assumption made earlier. Understanding those limitations helps stakeholders decide whether to improve the solution, address an organizational constraint, revise expectations, or pursue another change.
How to use the stages without turning them into a checklist
Use the six areas as questions to guide the work, not gates that every initiative must pass in a rigid order. The depth and form of analysis should fit the context, including the uncertainty of the need, stakeholder participation, decision governance, and the consequences of changing requirements. For a small, familiar change, some activities may be brief; for a high-impact or uncertain change, the team may need more discovery, explicit decision records, and closer traceability.
At each point, ask whether the team can explain the need, who is affected, what evidence supports the proposed direction, how requirements connect to the solution, and how value will be assessed. If it cannot, return to the relevant knowledge area and resolve the gap before treating the decision as settled. The BABOK Guide is IIBA’s globally recognized professional standard for business analysis; it is a reference framework, not a claim that every organization is required to use identical steps or deliverables.
