The timeliness of the published SDMX data should meet the requirements of the SDMX project. The release of data is usually linked to an internal calendar that is defined as part of the statistical business process.

At this step, it is also important to monitor the correct functioning of the entire system in order to effectively end the implementation project and move to a maintenance/support process.

The resources required to maintain and support the system and data flow(s) have to be operationalised in order to complete this phase.

Output of this phase:

• the functioning data exchange;
• the end of the implementation project
• move to a maintenance/support phase
