Collect Data for a Reliability Growth Analysis

The following table lists the data that you must collect to build a Reliability Growth Analysis.

Data Needed	Description	Notes
Asset ID	An ID that uniquely describes a piece of equipment or location, such as Asset ID or Tag ID. Reliability Growth Analyses can be conducted on any number of Assets.	This field is required and must be a character field. If the value in this field is blank, a blank Asset ID will be assigned to the data.
Cumulative Operating Time	The total amount of time that has passed since the piece of equipment or location was placed into service.	This field is required for an analysis based on cumulative operating time.
Downtime	The amount of time the piece of equipment or location is not in operation. You can use the date a piece of equipment or location is repaired or the day it returns to service to help estimate downtime. If this information is available, it can be used to make the analysis more accurate.	This field is optional for an analysis based on failure dates. Downtime is not used by analyses based on cumulative operating time.
Downtime Units	The downtime units.	This field is used only by analyses based on failure dates that are using downtime. This field must be in calendar time. By default, the time in this field is measured in days.
Failure Date	The date on which the piece of equipment or location failed. This data can have many different descriptions such as Out of Service Date, Shutdown Date, or Failure Date.	This field is required for an analysis based on failure dates and optional for an analysis based on cumulative operating time. For an analysis based on cumulative operating time: All failures must have a failure date, or no dates will appear in the analysis. Failure dates should be in the same order as cumulative operating time.
Installation Date	The date on which the piece of equipment or location was installed.	This field is optional. Note: Providing Installation Date will improve the accuracy of the analysis.
Operating Time Units	The operating time units.	For an analysis based on failure dates, this field must be in calendar time. For an analysis based on cumulative operating time, you can use custom time units, such as miles. By default, the time in this field is measured in days.
Measurement Name	The type of the measurements you are collecting (e.g., failures, safety events, or cost). Throughout the documentation, we use the term measurement to represent the pieces of data that are being collected.	This value is required for all analyses.
Number of Failures	The number of failures or amount of data that is recorded at each measurement.	This field is optional. If no data is provided for this field, the GE Digital APM system will assume there is one failure for each datapoint. If you are using grouped data, this field is required.
