Microsoft Project is used as the default scheduling package because of its seamless connectivity with the other Microsoft office applications and because it has its own programming language. The schedule information is stored in the JMS© database allowing dates from the schedule to be used directly by all the JMS© modules. Required dates calculated in the CPM network can easily be transferred to each individual document in the Engineering Management (EMS) module or to each piece of equipment in the Equipment Management (EQM) module etc. On the other hand, data from any JMS© module can be transferred to the CPM Schedule i.e. procurement cycle duration from purchase orders or contracts contained in the Procurement (PXS) module can be represented by one activity on the CPM Network.

Global project coding planning and understanding of the JMS© data organization can substantially reduce the quantity of activity on the CPM network making this an effective coordination tool. The basic planning coding such as the WBS, the Package list, Process system coding, the project organization etc. can be defined in the SCH module. This information is then readily available to the other JMS© modules.
