Abstract This paper describes the design of a user friendly interactive software package which can easily be used in both educational and industrial environments. The package contains applications for Quality Control Charts, Project Management, and Linear Programming. It is written in the BASIC programming language using the IBM Disk Operating System (DOS version 3.1). An IBM Personal Computer (PC, XT or AT) or compatible with one disk drive, a monochrome VDT and a line or dot matrix printer are required. The programs incorporate human factors considerations and the user is not required to have any previous computer programming experience. The package has data management options for adding new data, deleting data, listing data, storing data on a disk file and printing data collection forms for each program. The programs have been extensively validated using text book examples and comparisons with similar packages on main frame computer systems (such as EZLP, PPERT, LPRG, etc.). Based upon testing, this package was found to be easier to use and produced the desired results in approximately one third of the total time required by using the main-frame packages.
