Implementation
Evaluate different changeover methods: parallel, direct, pilot and phased
Direct - This method involves discontinuing use of the old system and immediately replacing it with the new system. There is no overlap between the old and new system.
Advantages
The new system is up and running immediately, no additional costs associated with duplicate processing of data or dual systems operating.
-
Pilot - Similar in many ways to phased implementation, but only some data from the old system is processed by the new system. The new system will operate alongside the old system, but only processing part of the data.
Advantages
-
Staff involved in the operation of the pilot system can help with the dissemination of training to other staff members
-
Parallel - In this instance the old and new system will operate side by side for a short period of time.
-
-
Phased - In this instance some parts of the system will be replaced by the new system while the remainder of the system continues to operate using the old information system.
Advantages
Supports gradual installation of new system and staff training (allows time for end user to become familiar with the new system).
-
Describe the different types of documentation: user documentation and technical documentation, and explain how they are used
User Documentation
User documentation provides the user with all the information they need to support them in the successful use of a piece of hardware or software. It may include:
-
-
-
-
-
Technical Documentation
Technical documentation describes how the system works rather than what it does. While user documentation is written for the end user, technical documentation is written for the professional involved in the design, implementation, testing and eventual maintenance of the system. It may include:
-
-
