Final answer:
To resolve user disagreements, the option that maximizes happiness for the majority and aligns with business objectives should be taken, typically prioritizing segments with the greatest impact on business success, while considering collective decision-making and compromises.
Step-by-step explanation:
The most appropriate way to resolve disagreement among individual users regarding requirements is to choose the option that produces the greatest amount of happiness for the greatest number of people, aligning with the principle of greatest utility. In practice, this means that decisions should cater to the segment that has the greatest impact on business success. This approach is favored because it helps optimize the product's market performance and ensures that the product meets the needs of its most valuable users. However, it's important to balance this with the principles of collective decision-making where compromises are often necessary. While the product champion or product owner is responsible for making the final decision, they should aim for decisions that advance the business objectives while considering the valuable input from different user classes.
