 The level of abstraction is one of the key elements in the task of planning business analysis information management. It refers to the degree of detail or generality at which the business analysis information is captured and managed. Deciding on the appropriate level of abstraction is crucial as it affects how information is understood, communicated, and used by stakeholders.

The context diagram represents the highest level of a data flow diagram (DFD). It illustrates the entire system as a single process and shows the interactions between the system and external entities (actors, users, or systems). This overview is essential in understanding system boundaries and external data flows.

BABOK® Reference – Technique: Data Flow Diagrams (Section 10.13):

“The context diagram is the highest level in a data flow diagram, showing the overall system boundaries, external entities, and major information flows.”

The primary purpose of the interview technique is to elicit business analysis information directly from stakeholders through a structured or semi-structured conversation. Interviews are one of the most commonly used elicitation techniques and can be conducted individually or in small groups.

Key objectives of interviews include:

Discovering stakeholder needs, expectations, and experiences

Clarifying requirements and business rules

Validating assumptions and capturing detailed information

While interviews can also build trust and identify stakeholder roles, those are secondary benefits. The main goal remains to gather the information necessary to support analysis and define solutions.

BABOK® Reference:

Described in the Elicitation and Collaboration knowledge area, under the technique “Interviews,” where the technique’s primary application is to collect elicitation results by engaging stakeholders.

Derive: relationship between two requirements, used when a requirement is derived from another requirement. This type of relationship is appropriate to link the requirements on different levels of abstraction. For example, a solution requirement derived from a business or a stakeholder requirement.

 The task of analyzing potential value and recommending a solution is included in the requirements analysis and design definition knowledge area. This involves assessing the potential value that could be realized from different solution options and recommending the most valuable solution to meet business needs.

When validating requirements, assumptions are defined so that the associated risks can be managed. Assumptions are considered to be true without proof for the purposes of planning and analysis, but they carry inherent risks if they prove to be incorrect. By defining assumptions clearly, business analysts and project teams can identify potential risks early in the process and develop strategies to address them, ensuring that the project remains on track and can adapt to any changes in circumstances.

Understanding the scope of elicitation when initially assigned work is crucial for planning the business analysis approach. This involves determining the type of business analysis information to be discovered and selecting the appropriate techniques for elicitation. It requires a clear understanding of the business domain, corporate culture and environment, stakeholder locations, and the dynamics of the stakeholders involved. This foundational step ensures that the business analysis activities are aligned with the project’s needs and objectives. References: The answer is corroborated by the Business Analysis Body of Knowledge (BABOK) Guide, which emphasizes the importance of planning the business analysis approach as part of the scope of elicitation1.

There are two commonly used relationships between use cases:

Extend: allows for the insertion of additional behavior into a use case. The use case that is being extended must be completely functional in its own right and must not depend on the extending use case for its successful execution. This relationship may be used to show that an alternate flow has been added to an existing use case (representing new requirements).

Include: allows for the use case to make use of functionality present in another use case. The included use case does not need to be a complete use case in its own right if it is not directly triggered by an actor. This relationship is most often used either when some shared functionality is required by several use cases or to abstract out a complex piece of logic.

When the number of requirements increases or the level of formality is raised, it becomes more challenging to manage and trace all the requirements. This is because each requirement needs to be documented, analyzed, and tracked throughout the project lifecycle to ensure it is met. As complexity grows, so does the effort required to maintain oversight and ensure that all requirements are accounted for and aligned with the project’s goals.

Video conferencing, electronic calendars, and electronic voting are all tools that facilitate collaboration among team members by allowing them to communicate and make decisions together, regardless of their physical location. These tools support the sharing of information and resources, coordination of activities, and collective decision-making, which are essential aspects of collaboration in business analysis.
