In an imaginary perfect world, many businesses would cease to exist. What’s an enterprise if not a vehicle to created (added) value. Arguably, in a perfect world, with all our wishes and desires fulfilled, there wouldn’t be a need to add value.
Production processes, especially mechanical ones, do, however, thrive on perfectionism. Initiatives such as lean six sigma are helpful to prevent variation and waste. When an automobile or technology maker messes up their production process, the cost for faulty parts and rebooting production is immense.
For more people-driven processes, it’s definitely worthwhile trying to eliminate errors. By stimulating communication and knwoledge, in combination with the right culture, there is a chance that less mistakes will be made.
Trying to perfect a predominantly people-driven process is costly. So much so that the cost outweighs the benefits. Aim for; as good as possible, but allow a margin for error. After all, done is better than perfect.
