Answer.

Defining target user segments is the foundation for developing relevant requirements, creating valuable functionality, and successfully launching a product. The analyst works with:

• Personas: a description of fictional users with different motivations, pain points, habits
• Market segmentation: identifying groups based on socio-demographic, behavioral, geographical, and business criteria
• Interviews and surveys: direct exploration of expectations and issues from representative users

Detailed segmentation allows for the development of solutions "tailored to the client," reduces the risk of creating unwanted features, and facilitates communication with the development team. All information should be structured and passed into the Product Backlog, SRS, or user scenarios.

Key features:

• The more precise the description of segments, the higher the relevance of the final product
• Regular updates of segments based on user behavior analysis
• Linking segments with functional and non-functional requirements

Trick Questions.

Can one segment (persona) be used alone to describe requirements?

No. Even the most niche products have several different user groups with distinct goals and scenarios.

Is it sufficient to identify segments at the start of a project and not change them later?

No, segments need to be periodically reviewed. After the product launch, new data and refined groups emerge.

Should a business analyst rely solely on the client's opinion when identifying segments?

No. It is necessary to rely on research, interviews with end users, and behavior analytics.

Typical Mistakes and Anti-Patterns

• Describing vague or overly broad segments without specific characteristics
• Ignoring "non-primary" users, who later turn out to be the majority
• Insufficient involvement of users themselves in the segment definition phase

Real-world Example

Negative case:

The analyst defined only one user segment based on management's perceptions.

Pros: Quick requirement description, simplicity of communication at the project's start.

Cons: After the release, it turned out that the main functions did not meet the needs of other segments, the product became unwanted.

Positive case:

The business analyst used a combined approach: conducted surveys, interviews, collected data on competitors' clients, and identified several segments with different motivations and requirements.

Pros: High product relevance, successful launch in new markets, flexibility in functionality improvement.

Cons: More time and resources were needed for segment research.
