Answer.

Business analysts use several techniques for analyzing and visualizing processes to effectively identify improvement points and explain functionality to developers and stakeholders. Here are the most popular techniques:

1. BPMN (Business Process Model and Notation). A standardized notation for creating diagrams that illustrate different working scenarios.
2. UML diagrams (Use Case, Activity, Sequence). Used for detailing technical and business requirements.
3. User Stories, Customer Journey Map. Help to understand the user's voice and touchpoints with the product.

Key Features:

• Allow for visual structuring of business processes and identifying bottlenecks.
• Provide transparent communication between different teams.
• Help prioritize tasks and track their status.

Tricky Questions.

How does BPMN differ from UML Activity Diagram?

BPMN is primarily intended for business users and describing business processes, while Activity Diagram is more for technical specialists and specifying data flow in systems.

Is it mandatory for an analyst to use only standardized notations?

No. Sometimes simple diagrams (e.g., Miro, MindMap) are sufficient for quick communication. The important thing is that the result is understandable to the target audience.

Can visualization replace textual description of requirements?

No. Visualization is just a complement for better understanding, but text description is necessary for formalizing and providing legal weight to the requirements.

Common Mistakes and Anti-Patterns

• Too complex diagrams without explanations.
• Using outdated formats (e.g., only MS Visio without integration into the project's ecosystem).
• Ignoring the diagram audience (e.g., overloading stakeholders with irrelevant details).

Real-Life Example

Negative Case: The analyst visualized a process in a rare notation that was unclear to developers.

• Plus: detailed elaboration. — Minus: no one could use the diagram.

Positive Case: BPMN was used for business stakeholders and Use Case Diagram for the team.

• Plus: communication is effective for all participants. — Minus: time is needed to create two types of diagrams.
