The power of laboratory management comes from the relationships between objects. A result value alone is meaningless; its meaning stems from knowing from which sample, by what method, and under what conditions it was produced.
The meaning of the chain
The diagram above illustrates why laboratory management is not simply a "record-keeping" job. The system's primary function is preventative control : preventing results from being entered with out-of-calibration equipment, preventing unauthorized analysts from running methods, and preventing the selection of standards that have expired.
These checks produce findings when performed later; they prevent errors when performed immediately. The difference is the difference between a nonconformity detected during an audit and a nonconformity that never occurred.
The extension of the supply chain in the chemical industry.
In the chemical industry, the supply chain doesn't end there; it extends to the product safety layer .
Formula → ingredient concentrations → substance hazard data → calculation engine → mixture classification → H and P expressions, pictogram → labeling and safety data sheet → multilingual publication → customer, carrier and competent authority.
Establishing this chain within a single system means that a change in the dosage on the prescription automatically affects the label and safety data sheet. In separate systems, this update is done manually and is often forgotten.
