Abstract: A process for developing an integrated implementation product for implementing large packaged application software produces four integrated components. The integrated implementation product includes a plan component, a training component, an user component and a data conversion component. Together, these components speed the implementation of large application software into an user company's computer system by reducing confusion, improving resource allocation and maximizing functionality utilization of the application software. In addition, there is a methodology for developing the integrated implementation product utilizing a seven phase design and development process. A process is utilized to implement a package software application onto an user's system and into the user's procedures through the use of an integrated implementation product which assists in the implementation and training of employees.
