and emergency procedures.
Correct installation of system software and application
software cooperating with ERP.
Software license, installation versions, back-up copies.
Power supply protection for critical devices cooperating
with ERP. Any possible errors detected on the
qualification stage should be corrected.
Operating qualification is aimed at verifying a configured
ERP system in regard to requirements included in
functional specification. This task requires completion of
acceptance tests and completed documentation’s
verification within the range of:
Operating business processes in ERP system.
Flow of documents in ERP system.
Precision of calculations and algorithms for threshold
detection and event detection
Generating reports and printouts/ hard copies.
Access to data records, modifications and copies in ERP
system.
Data transferred to other computerised systems.
Work logs and system logs (audit trail)
Any possible errors detected on the qualification stage
should be corrected.
Training end users can be undertaken by the
implementation partner or by key users from the
implementing company. Trainings are aimed at
transferring practical knowledge concerning system’s
functioning.
A system has to be validated before being put into
operation. Validation report should be compiled after
completion of all the testes included in the validation plan.
The decision to launch a system should be preceded by a
risk analysis for the system put into operation. The safety
of clients using our products has a superior value. Risk
analysis can indicate in what technological and functional
areas system failure may occur. Risk analysis is based on
tests results, opinions of key users from specific
departments and opinions of independent experts. On the
basis of this prepared risk analysis report and validation
report we can prepare a report approving a system for
operation in productive environment.
System usage After validation completion, an ERP system starts the
phase of exploitation. In case of ERP systems it usually
lasts for about 4-6 years and system functions without any
significant upgrade. The GAMP manual recommends
procedures that enhance a system’s stability and
development. Creating such procedures is a responsibility
of an ERP system user.
Performance qualification is aimed at verifying if an ERP
system functions steadily, in accordance with approved
specifications and procedures. Processing qualification is
completed at a defined time after formal launching of an
ERP system.
In the course of an ERP system validation we gain knowledge on the solution under construction both
in the IT, organisational and functional context. This knowledge is formally compiled in detailed
validation reports. The following documentation should be completed in the course of ERP system
validation (Rodriguez J. 2003):
Documentation concerning ERP system selection.
Documentation concerning implementation partner selection.
Documentation concerning URS, FS and DS completion.
