Final answer:
To increase capacity at a bottleneck, an organization can add more labor, improve human capital, or enhance technology, but must be wary of diminishing marginal productivity.
Step-by-step explanation:
Capacity can be increased at a bottleneck in several ways. One method is to increase the total quantity of labor by hiring more workers or extending the work hours of current employees. Another approach is to enhance the human capital of workers through training and development, which can improve efficiency and output. Additionally, improving technology can lead to more efficient production processes, and thereby increase capacity. It's important to monitor the impact of these changes to avoid the point at which diminishing marginal productivity kicks in, meaning that adding more workers leads to a less than proportionate increase in output due to factors such as insufficient capital or overcrowding.
