Adequate quality system, definition

From the theoretical point of view, having shown that we have relativistic Hamiltonians and procedures able to predict with sufficient quality 5/ and 6d states of actinide impurity ions with simple manifolds, this system is specially adequate to monitor their performance when the manifolds become more complex and to substantially show that quantum chemical relativistic ab initio calculations are definitely useful for the interpretation and prediction of physical processes involving the 5f" and 5f" 6d manifolds of actinide impurities. 

In ANSI/ISO/ASQ Q9001-2000, the American National Standard on Quality Management Systems—Requirements, reference is made to The model of a process-based quality management system, and the methodology known as Plan-Do-Check-Act. The standard gives a brief but adequate definition of the PDCA processes, as follows ... 

The functioning of every Water Distribution Subsystem (WDS) is related to the risk which is associated with the possibility of the occurrence of undesirable events, which may result in deterioration of water quality, lack of water, as well as reduction of water pressure in the water network. Risk associated with the operation of the entire WDS should be continuously monitored to ensure adequate safety level for water consumers. In the environmental engineering a basic definition of risk is applied. That definition presents risk as a multiplication of the probability of undesirable events occurrence, losses as a consequences of these undesirable events and the degree of system vulnerability to undesirable events (Kaplan Garrick 1981, Rak 2009, Tchorzewska-Cieslak 2011) ...
