You need to be aware of the many assumptions that can influence the
expected performance of your instrument.
What are your expectations for the performance of your instrument?
Are your expectations the same as everyone else in your organization?
• Who determines what is expected of the instrument while it is in use?
A quality engineer? A manufacturing engineer? A technician or
production line worker using the instrument to perform daily work?
• How long will the instrument be in use before it is recalibrated?
• What are the tolerances that indicate how far the instrument can drift
before it adversely affects the decisions that are being made as you
rely
on the values the instrument indicates?
