It is recognized today that COMPUTER SYSTEMS can be as complex
as building an AIRCRAFT or a SKYSCRAPER. Just as you would not change a PART in an aircraft or make a change in a buildings Plan w/o a full understanding of its consequences and FULL DOCUMENTATION; In the same manner and with the same care; CHANGES in the computer system must be carefully considered prior to implementing them and fully documented in order to prevent NEGATIVE consequences to a company; such as the very value of its STOCK and REPUTATION if there is a perception a company does not know how to MANAGE its Computer Systems.
