Training description: Monitoring of the conditions of the manufacturing environment is one of the key aspects of the Good Manufacturing Practice (GMP). The monitoring covers installations and systems which are critical for product quality, including air conditioning, purified water / water for injection / clean vapour, compressed air and protective gases systems as well as device, facility and staff spaces. The data collected during monitoring are subjected to a periodical review and analysis in order to show that the manufacturing environment conditions are stable and compliant with the acceptance criteria adopted.
In order to organise and present the monitoring data, statistical methods are used. They allow for the development of a correct model of the system’s operation and for the determination of control limits, which may indicate appearance of adverse trends and signal irregularities in the process/system, when they are exceeded. The methods of calculating control limits should be standardised, free from arbitrariness and applied consequently, together with a correct description of corrective and preventive measures to be taken when the limits are exceeded.
The course is intended for persons who analyse data collected during periodical environmental review of air and water quality and other utilities. During the course, requirements concerning monitoring of a manufacturing environment will be presented together with data analysis methods which can be applied for assessment of trends, seasonality, outliers, process modelling and for determination of control limits (alarm and action) for on-going monitoring of the manufacturing environment. Apart from typical statistical methods, various graphic methods will be presented, which can help establish whether there are any trends and if there are, to establish their nature. Every statistical issue will be at first discussed theoretically, and then developed during practical classes. After the course, the participants will be able to propose appropriate data visualisation and statistical evaluation techniques to be applied in monitoring of the manufacturing environment conditions of air, water and other utilities.
Requirements: ability to work with a computer in the Windows environment.
