An accepted practice is an example of a tacit business rule. Tacit business rules are those that are understood and followed by members of the organization but are not formally documented. They are often derived from the culture, norms, and shared understandings within the organization. These rules govern everyday behavior and decision-making processes implicitly, guiding how tasks are performed and how interactions occur without explicit instruction.

 In the context of collaborative games used in business analysis, the opening step is where participants are informed about the problem and the rules of the game. It is during this initial phase that they start generating ideas.  This step is crucial as it sets the stage for the exploration and iteration steps that follow, where ideas are further developed and refined.  References : The information is verified as per the Business Analysis Learning documents, which outline that during the opening step of a collaborative game,

When a BA considers opportunity costs , they are performing a cost-benefit analysis to determine the best solution. This falls within the task of " Analyze Potential Value and Recommend Solution " , where different design options or requirement implementations are evaluated for their expected value and opportunity costs (what must be forgone when choosing one option over another).

This involves:

Comparing expected benefits vs. associated costs

Evaluating risks and missed opportunities

Recommending the solution with optimal value delivery

BABOK® Reference:

Found in the Requirements Analysis and Design Definition knowledge area, this task emphasizes assessing the relative value of each solution option.

The correct answer is B . IIBA’s Business Analysis Standard states that an adaptive or iterative approach focuses on delivering value in small, prioritized increments . This is the clearest direct match to option B.

Option A is more characteristic of a predictive approach, where planning is done more extensively upfront and execution follows the established plan.

Option C is incorrect because adaptive approaches do not focus primarily on descriptive documents; they emphasize incremental value delivery and just-enough, just-in-time documentation.

Option D is also more aligned with predictive thinking, where progress is measured against a plan established in advance. Adaptive approaches continuously refine the work based on learning and priorities.
