You, PA, have been assigned as in charge auditor of a long-time audit client of your
firm, Mikla Tool Inc. (MTI). MTI is owned by George Mikla, an experienced
machinist. George established the business over 20 years ago, and it has grown into a
$10 million a year business, with an excellent reputation for high quality machined
parts. MTI has regular clients in the automobile parts sector and in the health care
sector. The company has recently begun producing parts for environmentally friendly
products, such as recycling containers. This is due to the business’ versatility in dealing
with a variety of metals as well as plastics using both manually controlled and machine
controlled (computerized) equipment. The following description is based upon your
review of prior files, and planning discussions with personnel at MTI.
Equipment suppliers have helped MTI develop efficient operations, by providing
sample programs for standard operations and by providing training to employees. One
of the suppliers unfortunately sent sample programs that had been infected by a virus.
George’s daughter, Tiffany, had to cleanse the servers and each of the machines using
her copy of the anti-virus software. When contacted, the supplier did not know that the
software was infected, and apologized profusely!
The company’s four CAD/CAM terminals and printers are connected to the company’s
central local area network. The local area network is maintained by Toni Lee, the owner
of a computer shop conveniently located three blocks away. All computer equipment,
software and supplies are now purchased from Mr. Lee, who is responsible for attaching
and maintaining equipment, upgrading software, and maintaining user profiles on the
network. To reduce the amount of Mr. Lee’s work as network administrator, he has set
up passwords by function.
There is one user identification code (userid) and password for accounting (shared by
Tiffany, George and the accounting clerk, Isabel). The plant supervisors share another
userid that is used for production control and to initiate the timekeeping system every
morning. A separate userid and password allowing for only enquiry into the job costing
system has also been set up, and can be used by all employees.
A standard routine has been set up to back up the accounting systems. Either Tiffany or
the accounting clerk inserts one of seven tape cartridges into the system at the end of
the day (they are labelled with the day of the week), so that the company has a full set
of accounting
backups for the week. Tiffany keeps these in her office. These are particularly
important, since during the last office move, two years ago, the original software for the
accounting system was misplaced.
The network has two central servers, eleven user stations, and five printers. The user
stations are set up as follows: four CAD/CAM, two time keeping, two production
planning and control, two accounting and one for George.
A good working relationship is extremely important for satisfying some of the
company’s larger customers. MTI has paid for computer equipment for each of the
supervisors, so that they have fully functioning computers at home. If a rush job
requires weekend work, then these senior personnel can work at home to get the
necessary quoting or design work completed. Since the ‘at home’ systems are identical
to the office systems Mr. Lee simply copied across the MTI systems to the home
