There’s an old saying that a chain is only as strong as its weakest link. Throughout the years, that expression has been adapted to fit different situations, including a “team is only as strong as its weakest player” or “your brand is only as strong as your weakest link.” In manufacturing, that weakest link is the machine that suddenly stops working or stops working properly, causing faulty products, delays in production and increased costs to fix the problem. The best way to avoid these problems is to ensure the machine is working optimally.
