What challenge does this address?
In the 1980’s quality guru Philip Crosby (Quality is Free*) stated that on average over 20% of a companies turnover was wasted correcting avoidable mistakes and having to do things again.
In the 21st century little has changed. Companies still do not put systems in place that encourage their employees to pay attention to detail and put quality first. This leads to them having to do the work again to correct simple errors.
