Data reconciliation is frequently discussed in connection with IT systems for optimization of technical processes in industry.

Data reconciliation as set out in VDI 2048 is indeed an interesting and technically complex process with which the quality of the operational process data and the  indicators based on those data can be significantly improved.

The technical and organizational conditions to be fulfilled in the implementation of this process are however less familiar. Publications on practical experience have to date been rare, mainly originating from the manufacturers of the relevant software tools.

This VGB Standard is intended to fill that gap. Its purpose is in particular to present and explain the method of data reconciliation to the plant operators as a modern, proven opportunity to improve operational processes.

This recommendation does not devote attention to the complex mathematical relationships involved, as these are described in VDI 2048.
