Agility definition

Different capillary columns are available for organic acid separation and analysis. In our laboratory, the gas chromatography column in all GC-MS applications is crosslinked 5% phenyl (poly)methyl silicone, 25 m internal diameter 0.20 mm stationary phase film thickness 0.33 pm (Agilent HP-5, DB-5, or equivalent). Several instrument configurations are commercially available, which allow for positive identification of compounds by their mass spectra obtained in the electron impact ionization mode. A commercially available bench-top GC-MS system with autosampler (Agilent 6890/5973, or equivalent) is suitable. Software for data analysis is available and recommended. The use of a computer library of mass spectra for comparison and visualization of the printed spectra is required for definitive identification and interpretation of each patient specimen. 

Our model has three main parts. The first part consists of the EC 61508 steps needed for developing the environment description and then the phases 1-4 (concept, overall scope definitions, hazard and risk analysis and overall safety requirements). These initial steps result in the initial requirements of the system that is to be developed. This is the key input to the second part of the model, which is the Scrum process. The requirements are documented as product backlog items. A product backlog is a list of all functional and safety related system requirements, prioritized by the customer. We have observed that the safety requirements are quite stable (e.g. the response time has to be less than the Process safety time for a fire alarm system), while the functional requirements may change considerably over time. Development with a high probability of changes to requirements will favour an agile approach. 

The structure of the paper is the following the first part includes brief presentation of terms and approaches applied in the model, namely agile manufacturing systems, resources definition, reliability and availability aspects and expert systems brief presentation. The second part is presentation of the model developed with its main assumptions, while the third presents discussion on results obtained, concluding it and introducing further research perspectives. 

Agile resources definition is the process in which the most important aspect is definition of corporate strategy including rough identification of scope and range of business activity. Human resources definition should cover all the capabilities potentially necessary to perform company s processes, while technical resources should be defined in a way providing synergy between human and technical elements of the system.

The second stage is resources definition based on processes within the branch considered. Some flexibility is advised in this stage to provide agility at the highest rate possible. 

A further incentive to agility can be created by linking processes to customer-based metrics. One such widely used measure is perfect order achievement . A perfect order is one where the customer gets exactly what they want at the time and place they want it. It will also usually be the case that different customers may well have different requirements and expectations, so the definition of what constitutes a perfect order will have to be specific to each segment, channel or even individual key accounts.
