A plan-driven approach to business analysis is an approach that plans upfront with maximum control of what the expected implementation would be. The waterfall project methodology supports a predictive approach in planning. In this approach, the business analyst defines the requirements at ahigh level and then seeks formal approval from the stakeholders before proceeding to the next phase of the project. This ensures that the scope and objectives of the project are clear and agreed upon by all parties involved. The initial requirements are also known as the business requirements or the scope statement. They provide a broad overview of the problem or opportunity, the desired outcomes, the assumptions, constraints, and risks1.
When it comes to communication in a plan-driven approach, the type of communication that is likely required is formal. Formal communication is communication that follows a predefined structure, format, and protocol. It is usually documented, approved, and distributed through official channels. Formal communication is suitable for a plan-driven approach, as it helps to ensure clarity, consistency, accuracy, and traceability of the information. Formal communication also helps to manage expectations, reduce ambiguity, and avoid conflicts or misunderstandings2.
The other options are not correct types of communication that are likely required in a plan-driven approach:
A. Face-to-face: Face-to-face communication is communication that occurs when the participants are physically present and interact directly with each other. It is usually informal, spontaneous, and dynamic. Face-to-face communication is more suitable for an adaptive or agile approach, as it helps to foster collaboration, feedback, and trust among the stakeholders2.
B. Ad hoc: Ad hoc communication is communication that occurs without any prior planning or preparation. It is usually informal, flexible, and responsive. Ad hoc communication is more suitable for an adaptive or agile approach, as it helps to accommodate changes, uncertainties, and emergent issues2.
C. Chain of command: Chain of command communication is communication that follows the hierarchical structure of the organization. It is usually formal, authoritative, and controlled. Chain of command communication is not a type of communication that is specific to a plan-driven approach, as it can be used in any organizational context. However, it may not be the most effective or efficient way of communicating, as it may create delays, distortions, or barriers in the information flow2. References:
