This year you obtain a new client, Stem Corporation, a local distributor of appliances. Before becoming your client, Stem had installed a microcomputer-based accounting system to handle its payables, receivables, payroll and general ledger. Stem purchased its microcomputer with off- the-shelf software and appears very pleased with it. You notice that the computer sits on the bookkeepers desk. You ask Antonio Chua, the CEO, about his thoughts about the computer system, and he states:

The system is absolutely great. It has already saved us a lot of time and money. I get reports then I want them, not days later. In fact, it is so good, why dont you try it? The password is STEM. You can go ahead and use it. If you want any backup files, they are stored in the supply room. We sure saved a lot of money by purchasing the system from a mail-order operation. A systems analyst wanted P20, 000 to help pick the best system for us, and a local dealer wanted P16,000 more for comparable hardware and software.

Requirement: Identify the concerns about the system that STEM uses. Your answer must be in paragraphs and must contain a minimum of 300 words.
