When Roberto decided to try a new soft drink brand due to the unavailability of his favorite, what type of problem-solving is illustrated?

The situation described with Roberto highlights limited problem solving, which typically occurs when consumers face a situation that requires more thought than routine purchasing but not as much as extensive decision-making. In this case, Roberto is not making a choice with an overwhelming amount of information or many options, nor is he purchasing the product on impulse or as part of a habitual choice.

Instead, he is simply reacting to a lack of availability for his preferred brand and is willing to consider an alternative soft drink. This indicates that he is engaging in a moderate level of analysis regarding his purchase, weighing options that are readily available to him without delving deeply into complex considerations or extensive research. Hence, the decision-making process aligns with the characteristics of limited problem solving, where some thought is applied, but it does not involve significant effort or time.
