How can I guarantee that the computer system I’m using is right for me?
Selecting the right programs, choosing the right equipment and implementing the diverse applications are factors to consider when you computerize your business. There are three common types of software. Compilers and interpreters translate programs that are written in human-readable programming language to the computer language that the CPU understands. The operating system software controls the individual components of the computer. The computer generally comes with system software which must be loaded into memory before the application can start.
Software for specialized functions such as accounts receivable, payroll check writing, posting or inventory reporting are usually purchased separately from the computer hardware.
In order to determine your needs, make a list of all the functions of your company where speed and accuracy are important for mass amounts of data. These are referred to as applications.
Prepare a list of all the reports that you are currently producing for each of these applications. Make sure to include any preprinted forms such as vouchers, checks or billing statements. If these forms don’t already exist, come up with a good idea of what you want. List the frequency with which each report is to be generated, who will make it and the number of copies necessary.
Prepare a hand-drawn version that also lists the circumstances in which you would like the data shown. Write a list of all the materials that are used as input into your manual system for each application. These may include, but are not limited to, work orders, receipts, time cards, etc. Detail who will create them, how they will get into the system and the time in which the items take to be created. For the appropriate time period, make a maximum and average expected number of these items produced.
