Answer.

In integration projects, the business analyst must become the link between technical and non-technical stakeholders. The main task is to ensure mutual understanding among the parties so that the requirements, risks, and constraints are understood by all participants, and the documentation contains the necessary details for integration.

Key features:

• Facilitating meetings: the analyst structures communication processes, helps participants speak in a language understandable to each other, clarifies technical details for the business and business tasks for developers.

• Documenting interface requirements: it is important not only to describe the requirements but also to clarify agreements on data formats, transmission channels, error handling, and version management of integrations.

• Aligning project goals and constraints: the analyst identifies hidden risks, helps to agree in advance on success criteria and control points.

Trick questions.

Can the business analyst fully delegate the documentation of the API to technical specialists?

No. The analyst must ensure that business requirements are correctly reflected in the interface documentation and that real business scenarios are supported by the technical solution.

Is it sufficient to agree only on the formats of incoming/outgoing data?

No. It is extremely important to clarify business rules, handling of exceptional situations (for example, what to do if the integration is unavailable), availability constraints, and access rights.

Is the participation of the business analyst mandatory when discussing architectural decisions?

Yes, even if he does not make the technical decision, the analyst must ensure that business aspects and constraints are considered in the architectural design.

Common mistakes and anti-patterns

• The business analyst does not participate in technical meetings, leading to a desynchronization of requirements and implemented solutions.
• "Word-for-word" translation of documentation from business to technical: context, specifics of integration, and important error handling scenarios are lost.

Example from life

Negative case: When integrating CRM and an external service, the analyst did not participate in preparing technical specifications. Pros: the technical team developed the API faster. Cons: the integration did not support necessary business rules, resulting in data loss.

Positive case: In a similar project, the analyst participated in all stages of discussion, involving both business and technical teams. Pros: the integration covered all real scenarios, testing was successful. Cons: more time was spent on clarifying requirements.
