In engineering and operational contexts, efficiency is often represented as a percentage. But efficiency is also an imperative for progress and innovation. Being more efficient really has no limits because what may be 100% efficient today can only ever be measured against what the current solutions can provide to drive that efficiency. When new technology is introduced, efficiency has to be reassessed because technology is constantly evolving. Thus, what may have been viewed as 100% efficient a year ago may be considered considerably less efficient by today’s standards.
