Question 10 - STQB-Agile-Public discussion

In the context of the provided User Story for the Operator-Instructions module of an industrial Espresso machine, option B is the most pertinent risk. This option states, 'The instructions may be incorrect or appear in the wrong order. Probability: Low. Impact: High.' This risk directly affects the core functionality described in the User Story, which is to provide operators with accurate instructions for steaming milk.

Agile methodologies emphasize the importance of delivering value to the customer through functional and usable increments of the product. Incorrect or improperly ordered instructions would directly undermine the usability of the Espresso machine for its intended operators, potentially leading to operational errors, customer dissatisfaction, and a failure to deliver the intended value of the User Story.

While the other risks mentioned (A, C, and D) might have their relevance in broader project considerations, they do not directly impact the achievement of the User Story's goal as much as option B does. The risk of incorrect or out-of-order instructions is particularly significant because it could lead to improper operation of the machine, resulting in quality issues with the product (steamed milk in this case) or even damage to the machine, both of which have high impact on the project's success.

Therefore, option B is the verified answer as it most accurately reflects a risk that is directly related to the achievement of the User Story's objective, aligning with agile principles of focusing on delivering functional and valuable product increments to the customer.
