Candidates are expected to be able to:
The implementation strategy is determined in this early stage. Brown, Vessey, Create master implementation script The first initial requirements analysis is made, consisting of the requirements below.
Venture, Construct Time planning A first time-planning of the implementation process is being constructed. Rooijmans, Define Organizational requirements The organizational requirements are defined here Rooijmans, Prepare organization Description Install requirements In order to prepare the organization, the defined requirements are installed.
The organization is being prepared and the IT installed on test-machines. Rooijmans,Eason,Microsoft, Test requirements The requirements are tested to see if the organization is ready for the implementation Rooijmans, Redefine master implementation script The master implementation script is refined with the new information gathered in the process with the activities below.
Rooijmans, Define criteria indicators In order to test the new system, criteria indicators are being created. With these plans, the organization can respectively attempt to correct the mistakes that are made and fall back if the implementation in a certain stage of the process fails. Microsoft,Rooijmans, table Conversion Description Make catch ups The conversion process is started, a number of activities run parallel.
During this stage, catch ups are being made using the old system. The old system is leading, but the new one runs parallel. All changes in the system, have to be put in the new system. Microsoft,Rooijmans, Control system The system is being controlled at all times by the control system.
With the defined indicators and system run characteristics, errors and mistakes are tracked down. Microsoft,Rooijmans, Run leading old system The old system is leading; processing the actual data. Run new system The new system is running parallel with the old system and is closely monitored.
Microsoft,Rooijmans, Translate catch ups in new system If the criteria are met, the catch ups are translated and transferred in the new system and the conversion process comes in its next stage. Microsoft,Rooijmans, Make catch ups Catch ups are made for safety purposes, even when the new system is leading.
Microsoft,Rooijmans, Run old system The old system runs as a backup, for safety purposes Run leading new system 1 The new system is leading and in full operation.
All the transactions and changes in the system are being handled here. Closing parallel adoption Activity Description Run leading new system 2 All catch ups and controls are closed down. The new system is the only system in operation.
Microsoft,Rooijmans, Disable old system The old system is not necessary anymore and is disabled. Microsoft,Rooijmans, The concepts from figure 1 are defined in table below. Concept definition list Concept Definition Implementation strategy The strategy that will be chosen to implement the new system.
The options are big bang, phased, parallel adoption, pilot conversion or a combination of those four. Turban,Rooijmans, Implementation script Raw version of the actual conversion scenario, consisting of organizational requirements, IT requirements and an initial time planning.Conversion methods for implementing the database solution • Direct conversion • Parallel conversion • Phased conversion • Pilot conversion The distinction between a phased conversion and a pilot conversion is blurred in this situation.
Pilot conversion . Download-Theses Mercredi 10 juin Parallel adoption is a method for transferring between a previous system to a target (IT) system in an ph-vs.com order to reduce risk, the old and new system run simultaneously for some period of time after which, if the criteria for the new system are met, the old system is disabled.
