You can identify many things such as product defects by determining the number of mistakes one has done. This is the same as calculating the number of corrections. Why is it so important that we identify them? Well, for one, the smallest error can have a big impact on how the company presents itself – be it written work or bugs in software, it's equally important that you calculate them. For example, if the HR performance management software is malfunctioning, it could mess up the whole process – this could also be the only way of figuring out whether or not you should invest in software like Orange HRM.
