Checking for Errors - Why Bother?

Is checking for errors important? Why bother for the process and normally, takes longer time to execute a task? There must be a reason and this is why.

At a glance, this promotional panel at GSC Pavilion KL for the upcoming Life (2017) movie looks great with good printing resolution.

However, when I take a closer look, I got confused with who is Ryan Reynolds and Rebecca Ferguson. They designer got mixed up with the two main stars in the movie.

Errors like this do happen and it is very common but the implication of some errors can be fatal!

Is this the designer fault to allow such error to occurs? Maybe but they cannot be blamed for everything. Sometime it could be due to the constraint of time to push things out for production and there is no checking in the entire process - from the person who provides the information, the designer who didn't check or ignorance, the superior who need to approve the artwork (if any), the printer, production, and lastly the personnel at the cinema.

Anyway, we all make mistakes. If only there is compliance to a proper control process, personnel who are more alert or maybe more time were given to designer (whom might be too exhausted with too many deadlines to fulfill until their quality is being compromised), the error could have been corrected before it goes public.

Somehow, I belief in this: "Fast, Good and Cheap - we can only pick TWO". What say you?
