In every ESKORT System there are 3 aspects of the system which need to be
maintained and supported:

• The domain content of the system – knowledge bases, help files, reference
  material, etc.
• The system’s configuration – internal data model, data mapping, calculation
  algorithms, etc.
• The system’s core functionality as represented by the relevant parts of the
  ESKORT Compliance Platform and all modifications made to these parts in
  connection with the establishment of the specific system. 

Intracom IT Services Denmark A/S provides tools which enable the customer to
maintain the first two parts (the Customer Maintained Part or CMP) of the system
itself. The normal split of responsibility is that the customer’s end-user
organization is responsible for maintaining the first of these parts, while the
other often requires the involvement of the customer’s IT department.
Responsibility for maintenance and support of the third part of the system (the
Supplier Maintained Part or SMP) is provided by Intracom IT Services Denmark and
its local partner under contract.

The CMP should be maintained by the customer on an on-going basis as
circumstances demand – e.g. the tax laws change, customs avoidance behaviour
changes etc. Once the CMP has been updated the system must be tested by that
part of the customer’s organization responsible for operational roll out.
Thereafter it can be released to the end-users. Such a release is termed a User
Release.
The SMP is maintained with varying frequency depending on which maintenance
services the customer elects in its maintenance contract. When the supplier has
made corrections to the SMP these are released to the customer in the form of a
Technical Release. The customer must then integrate this change with any changes
to the CMP (if there have been any which coincide with the SMP) and test the
system before making a User Release.
