The ERP system needs regular
maintenance in order to function properly. The ERP plan needs revision
and updating as per the changing situations in the organization. The ERP
system should be reviewed regularly.
The review comments and suggestions should be incorporated into the system.
Also the ERP system needs fine-turning as the employees become familiar with it.
Once the ERP system has reached a stable state necessary action should be taken
to improve the performance.
The ERP tools that are implemented are another area that needs maintenance.
The project manager should be in regular contact with the vendors to see whether
any upgrades or updates are available. All patches and upgrades should be
installed to ensure that the tools are working at their maximum efficiency.
Employees should be given refresher courses on the new functionality that
gets added with each new upgrade. The training documentation should also be
updated so that it is in sync with the procedures and processes.
If a customer (meaning a user) wanted to add a field, change the look of
a screen, or add an extra step to a process, then an enhancement would be developed. Analysts
develop a functional specification and a technical specification, and
then the developers code the enhancement.
Software customization: Once implementation
begins, project teams will inevitably find at least a handful of
functionality gaps that they would like to address by changing the
software. It is important to prioritize and limit the amount of
customization to help contain costs. Customized ERP software may have its advantages,
but there are more
Creating custom code
can be a time consuming process and involves inherent risks that can
only be eliminated with exhaustive testing. Too often, quality assurance
is undercut in order for the project to come in on time, creating risks
associated with “buggy” software. This, in turn, leads to a less stable
and reliable system. The focus on heavy customization efforts may also
detract attention away from other, more critical, aspects of the ERP
implementation. For more detailed information about customization,

don’t add value by default. By default they subtract value, at least in
the short run, through costs associated with analysis, design, and
development time and in the long run, through upgrade, maintenance, and
support. Firms should ensure that the net result is value added through
increased productivity, higher profitability, reduced error, or another
measurable benefit. Each time a customization is contemplated, the
impact of these issues on the system’s ROI should be quantified and
supported with an accurate and detailed business case.
