To achieve a feasible production plan in the case of capacity constraints, which option is effective?

Selecting an alternative mode on a resource is an effective approach to achieving a feasible production plan, especially when faced with capacity constraints. This option allows for flexibility in resource utilization by potentially switching to different methods, tools, or processes that may not be constrained by the same limitations as the primary mode. For example, if a specific machine's capacity is maxed out, choosing a different machine or a different operational method can alleviate the bottleneck and better balance the workload across resources. This ensures that production processes can continue smoothly without significant delays.

This approach also helps optimize resource use and can lead to more efficient operations without needing to invest in increasing overall capacity or making extensive changes to other processes. Thus, by selecting alternative modes, one can effectively navigate and mitigate the impacts of capacity constraints, leading to a more achievable and realistic production plan.
