WEEK BLOG 9

Based on the article (Shelly, Cashman, Rosenblatt, 2006) post discusses the four change over methods mentioned in the textbook in relation to with the Academic Misconduct Management System (AMMS). The purpose of this blog to suggest more improved approaches for the Academic Misconduct Management System. The four methods are

1. Direct cut-over
2. Parallel operation
3. Pilot and
4. Phased approach

This post discusses the benefits and drawbacks of the approach that can influence the AMMS when it undergo changes in the system.

Direct cut over

This method is more complex in implementation the result of failure are maximum. In this method the time of implementation can be quick and can be executed with minimum modifications , but the loss over the result cannot be predicted. Though it has negative impacts the introduction of this method is more suitable in carrying out the new system for the CQU’s new launch of AMMS information system.

Pilot

In this pilot method the approach for the new system is carried as a part of system integration which cannot be more suitable in the implementation of new AMMS. Because the approach will be in action for a part , based on the results the changes in the approaches are restructured for further processing the new system. So this system cannot be recommended for CQU new information system.


Parallel operation

This method finds to be more expensive in implementation for the new system. As it involves a duplication of the all the process that are carried during the execution of the steps that are required for the new system. The AMMS relies on the system for processing the functions and not based on the value of storage of data. So this will not fit the cost effective information system method.


Phased approach

This approach is represented in a step by step procedures in the implementation for the new system for the CQU Academic Misconduct Management System. In every phases the method is tested as a part which is out of our scope for AMMS. Because AMMS is a integrated system supporting for the whole system in academic system in all campus network. So this method of approach cannot be sufficient for the CQU’s information system.
