Scheduling tests in your Instrument Management application will also help plan your workflow as tests can be run from the planner. As the scheduler in the Instrument Management application can be set to reference the work order number in your plant maintenance system, Kelton recommends scheduling tests in Instrument Management even when using another application such as SAP or Maximo.
