IMPLEMENTATION METHODOLOGIES: What implementation technique to use INTRODUCTION What is implementation? Implementation in some books is also referred to as conversion. "Conversion is the installation of the new, tested software, making it fully operational. System installation is part of this conversion process. It consists of two activities; database creation and system changeover. Besides system installation, conversion consists of writing new work procedures, completing all system documentation, training users, and conducting acceptance tests of the system by user groups. The end result of this conversion effort is the release of the new system for day-to-day use" (Eliason, 1987).Lucas (1981), on the other hand states that implementation is a continuous process that runs from "original suggestions" through "feasibility study, systems analysis and design, programming, training, conversion and installation of the system." Zwass (1992), agrees with the above statement but adds that it "is the process of preparing people in an organization for a new system and introducing the system into the organization." Thus implementation involves replacing an existing system with a new system after preparing people, facilities and equipment within and around the environment where the new system will be introduced.There are various ways of implementing a new system but how does an organization select which of the methods to use? Let us first look at why we need to implement and the various methods used before we analyze the selection criteria.OBJECTIVES/PURPOSE OF IMPLEMENTATION The main purpose of implementation is so that the existing system can be replaced with the new, tested and documented system (Adams,1985). There are various reasons why an organization may want to replace an existing system, ranging from wanting to speed up transactions to acquiring a competitive edge in its field/industry. Replacing of an old system will, for whatever reason, require creation of new files to replace the old files and the habits of affected employees will definitely change.The new system should also be fully utilized by not only training employees on how to use the system but on how to understand and appreciate the newly installed system (Adams, 1985). This objective is very important because there is usually resistance from employees to change, which in this case is the new system. Therefore employees should be assisted to overcome the probable fear of losing their jobs with the introduction of the new system. This can be done through training and education and in this way the employee will be more keen in trying to understand how the system works. Thus fully utilizing it to its maximum.IMPLEMENTATION TECHNIQUES/METHODS There are four popular conversion methods which are as follows:- DIRECT CONVERSION/ABRUPT CUTOVER This method takes effect when suddenly at a certain point the old system is replaced with the new system (Zwass, 1992). It usually produces a gap of time...
