Evaluating Hardware, Software, and Services
Hardware Evaluation Factors – physical and performance characteristics
Software Evaluation Factors – similar to evaluating hardware
Evaluating IS Services – services may be provided by suppliers of hardware/software or by third parties; do the services address your needs?
Other Implementation Activities
Testing – testing and debugging are important, does the system work as it should?
Data Conversion – new implementations often require replacing software and databases
Documentation – an important means of communication, often overlooked
Training – training users is vital, usually under-budgeted, and expensive
Post implementation Activities – Use and Maintenance – the longest and most costly phase of a system’s life; correct errors, improve performance, adapt to changes in the business environment
Systems Maintenance – making changes to the system
Corrective – fix errors
Adaptive – adding new functionality
Perfective – improve performance
Preventative – reduce chances of future system failure
Post implementation Review – ensure the new system meets established business objectives
System Conversion Strategies – cutting over to the new system
Direct – simplest but most dangerous method, turn off the old system and turn on the new one
Parallel – most expensive but safest, run both systems until everyone is satisfied, then turn off old system
Pilot – let only a select few users use the new system until they are happy, then implement the new system for everyone; best user representation can be selected for the trials
Phased (Modular) – gradual conversion one module at a time, combines best of both direct and modular while minimizing risks
