This topic describes the fields found on the Worksheet tab of the PFD worksheet. For a description on how to use the Worksheet tab to document the process steps, see PFD Worksheet Tab.
Note: The fields that are enabled in the interface and the options available in configurable drop-down lists will depend on the interface style settings that have been defined for the current project. You can choose Project > Management > Configurable Settings > Interface Style to open the Edit Interface Style (This Project) window and change the settings for the current project.
Process Step/Operation Records
Sources of Variation: A description of the process inputs or variables that affect the results in each process step, such as improper setup, machine calibration and maintenance, contamination of materials, etc.
Op Seq Number: The reference number for the process step. This is a required column.
Operation Type: The type of process or activity, such as an assembly, an inspection, a fabrication, etc. The drop-down list in this column can be configured per project.
Operation Type Symbol: The graphic symbol associated with the type of process or activity; for example, inspection procedures may be represented by a square symbol. The symbols can be configured per project.
Deliverables: A description of the results of each process step.
Changeover: Allows you to flag the process steps that are affected by changeover activities. The drop-down list in this column can be configured per project.
Operation Description: A description of the process step from the product's perspective. The process that the product goes through must be described step by step. This is a required column.
User-defined fields: Up to five text fields, two date fields, two number fields and two drop-down lists.
Product Characteristics Records
Classification: An abbreviation of the classification that has been assigned to the product characteristic, if any. This field is used to identify characteristics that require special manufacturing control (e.g., Critical, Significant, Key Leading, etc.).
Product Characteristics Description: A description of the product characteristics (outputs) that are affected by each process step; for example, thread depth, wax thickness, length of a cut, etc.
User-defined fields: Up to three text fields, one date field, one number field and one drop-down list.
Process Characteristics Records
Classification: An abbreviation of the classification that has been assigned to the process characteristic, if any. This field is used to identify design characteristics that require special manufacturing control (e.g., Critical, Significant, Key Leading, etc.).
Process Characteristics Description: A description of the process characteristics (inputs) that require control to ensure that the product characteristics meet the specification; for example, furnace temperature, flow pressure, coolant concentration, etc.
User-defined fields: Up to three text fields, one date field, one number field and one drop-down list.
