MACHINE INFORMATION GATHERING
In order to implement a structured, reliable and efficient machine control system, requirements of
the machine should be gathered thoroughly in a formal manner to insure details of the system
design or functionality are not overlooked. The sequences of steps for machine information
gathering are shown in the diagram below. Note the sequence of the diagram is in logical
development of the application. Brief descriptions of the information gathering steps and
references to examples of the steps are located in eng.MCD.05.096, MP2000 Best Practices
Information Gathering. Basic Design template example is also referenced in eng.MCD.05.031
