A plan-driven business analysis approach is a methodology that follows a predefined and structured process, where the requirements and the solution are fully defined and agreed upon before implementation begins. A plan-driven approach is suitable for projects that have low complexity, uncertainty, or volatility, and that require stability and predictability of the scope, schedule, and budget. A plan-driven approach is characterized by its formal and rigid nature, where each project phase must be completed before moving on to the next one. Therefore, the following are not appropriate for a plan-driven business analysis approach:
Informal: This means that the communication, documentation, and validation of the requirements and the solution are done in a casual and flexible manner, without following any standards or rules. Informal methods may lead to ambiguity, inconsistency, and misunderstanding of the requirements and the solution, which can cause delays, errors, and rework in a plan-driven approach.
Face-to-face: This means that the interaction and collaboration among the stakeholders are done in person, rather than through electronic or written means. Face-to-face methods may enhance rapport and trust among the stakeholders, but they may also introduce challenges such as scheduling, availability, and travel costs in a plan-driven approach.
Ad hoc: This means that the business analysis activities and tasks are done in a spontaneous and unplanned manner, without following any methodology or process. Ad hoc methods may allow for creativity and innovation, but they may also result in chaos, confusion, and waste in a plan-driven approach.
Option D is incorrect because formal is appropriate for a plan-driven business analysis approach. Formal means that the communication, documentation, and validation of the requirements and the solution are done in a systematic and rigorous manner, following established standards and rules. Formal methods ensure the quality, completeness, and alignment of the requirements and the solution, which are essential for a plan-driven approach.
