A Guided Inspection step is used to create an automated, color-coded work instruction that distributes a single part number or reference per activity. A Guided Inspection step drives the Production user to step through each instance of a part on an assembly, changing the part to Green when it is verified.
Note
Activities do not display in NPI for Guided Inspection steps; they are generated dynamically when executed in Production after the operator loads the batch and the operation. The activities are controlled by the Activity Splitting tab in the Settings dialog for a Guided Inspection step after the part assignments are made.
To view the activities for a Guided Inspection step in NPI, select the Show Shop Floor button at the top of the Process Definition window after first saving the operation.
Tip
You can also use a wizard to quickly create a Guided Inspection step for a new operation. See Create a step using a wizard for details.
Create a Guided Inspection step
Log into the NPI client application.
Open a new process definition and create a new operation. (See Add a new operation to a process flow for more information.)
Double-click the operation to open it for editing.
Select the Add button under Step List in the Process tree, then select Guided Inspection Step.
Double-click the Guided Inspection step to open the Settings dialog.
Use the following tables to make your selections for the step in the Settings dialog.
When you're finished making selections for the step, select OK to confirm your choices.
Settings dialog - Basics tab
Option | Description |
---|---|
Name | The name of the step.
For details about creating and saving step templates, see Create a process, step, or operation template. |
Default Instruction | Enter the default instruction for this Guided Inspection step. For example, "Use the torque wrench to tighten 12 1-inch coarse bolts on the unit to 188 lb.-ft.)." |
Operator Interface Template | The Operator Interface template to apply to the step. See Operator Interface templates for more information. |
Assigned Workstation | The assigned workstation where the step and activities will be performed by a shop floor operator. See Create a factory and set up factory resources for more information. |
Any Order Mode (Activities can be viewed in any order) | All the activities associated with the step may be viewed in any order. |
Is Step Required? | The step cannot be skipped by a shop floor operator. |
Activities may be executed without starting a unit | Any activities associated with the step may be executed by a shop floor operator without first scanning or entering a UID to start the unit in production. |
Frequency |
|
Activity Completion Acknowledgement | Add Acknowledgement to: The shop floor operator must acknowledge completion of All Activities, the First Activity, or the Last Activity associated with the step. |

Settings dialog - Color Coding tab
Option | Description |
---|---|
Color Palette | The color palette to use for color coding parts. Select a color palette from the Palette Chooser drop-down. Tip You can save custom color palettes for later use which can save you valuable time when creating future process definitions containing color coded steps.
|
Look Behind | The Look Behind feature is typically used in manual assembly operations where an assembler is shown the parts placed by the previous operator so that their work can be verified prior to performing their own tasks. Parts placed by the previous operator are color-coded/highlighted using a pre-selected Look Behind Color.

Settings dialog - Activity Splitting tab
The Activity Splitting tab of the Settings dialog for a Guided Inspection step allows you to define or limit the number of color-coded parts to be displayed on each page. (Since the human eye can typically discern about 10 different colors at any given time, it is best to limit the Max Number of Items per Activity to no more than 10.) On this tab of the Settings dialog, you can also define the ordering and sorting of parts listed for each activity to help focus operator attention on a specific area of a PCB for placing or inspecting parts.

Option Codes | Displays a list of available option codes. Note Option codes are only used with configurable (CTO) assemblies.
Note For details about option codes, see Option codes for configurable assemblies. |
Assigned Option Codes | Displays the option codes assigned to this step. |
Use Logical Expression | Select the Use Logical Expression button on the right side of the dialog to define option codes for a step in the form of a logical expression (comprised of available option codes plus the logical operators: AND, OR, and NOT, and brackets to identify precedence). |
