Answer:
The answer is a) offloading work from constrained workstations.
Step-by-step explanation:
In the The Theory of Constraints (TOC) the idiom "a chain is no stronger than its weakest link" is adopted. This means that processes, organizations, etc., are vulnerable because the weakest person or part can always damage or break them or at least adversely affect the outcome. Therefore, if you offload work from constrained workstations you will streamline your production process.
