This stage converts the system to operational status. The work includes
converting existing files (if any) or creating the initial information base, training
all personnel involved with the system (user and EDP), and instituting control
and operational procedures through pilot or parallel run phase-in. All
documentation from previous phases should be finalized. Conversion and
installation procedures should be reviewed and tested. The project manager
should issue a formal Project Completion Notice for approval. IT Audit Manual Volume III 86 IT Audit Manual
Audit objective: To ensure that the system and any file conversions
properly move from the development status to the operational and
IN.1. Whether there is a formal SDLC methodology in place for system installation,
including but not limited to a phased approach of training, performance sizing,
conversion plan, testing of program, group of programmes and total system, a parallel

implementation and post implementation review and modification.
IN.2. Whether the accuracy, completeness, and authenticity of the files created by
conversion are ensured through the use of appropriate control techniques.
IN.3. Review the conversion plan before it is executed, referring to the List of Minimum
System Processing Controls.
IN.4. Verify that control techniques are being included in the conversion process to satisfy
all control concerns.
This is an extremely critical process. No doubt about the integrity of the data
in the new files should be tolerated. Control techniques such as one-to-one
checks, may have to be used.
IN.5. Verify that the conversion was carried out according to plan.
IN.6. Verify that training was carried out according to the schedule prepared in the
Implementation stage and that any variations have been agreed to by user
