21) 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 computers. Files can be easily taken home and then brought back to the office using
