The method of claim 1 , wherein at least three types of indicator are used, a first displayed indicator indicating that the step in the measurement design, setup and/or monitoring process is not completed and/or that a key performance indicator associated with a step in the measurement design, setup and/or monitoring process has passed a threshold, a second displayed indicator indicating that the step in the measurement design, setup and/or monitoring process is completed and/or that a key performance indicator associated with a step in the measurement design, setup and/or monitoring process has not passed the threshold, and a third displayed indicator indicating that the step in the measurement design, setup and/or monitoring process has not been started.

6. The method of claim 1 , comprising displaying an icon, as the indicator, at least partly overlaying the one or more of the plurality of graphical user elements.

7. The method of claim 1 , comprising displaying at least one graphical user interface element regarding the physical design of a metrology target, the at least one graphical user interface element enabling access by the user to one or more steps to configure one or more geometric parameters of the metrology target.

8. The method of claim 1 , wherein the indicator displays, or displays upon user flyover, of a value of key performance indicator of the measurement design, setup and/or monitoring process.

9. A non-transitory computer program product comprising machine-readable instructions for causing a processor system to cause:

display of a plurality of graphical user interface elements, each graphical user interface element representing a step in a measurement design, setup and/or monitoring process and each graphical user interface element enabling access by the user to further steps in the measurement design, setup and/or monitoring process for the associated step of the graphical user interface element; and

display of an indicator associated with one or more of the plurality of graphical user elements, the indicator indicating that a step in the measurement design, setup and/or monitoring process is not completed and/or that a key performance indicator associated with a step in the measurement design, setup and/or monitoring process has passed a threshold.

10. A system comprising:

an inspection apparatus configured to provide a beam on a measurement target on a substrate and to detect radiation redirected by the target to determine a parameter of a lithographic process; and

the non-transitory computer program product of claim 9 .

11. The system of claim 10 , further comprising a lithographic apparatus comprising a support structure configured to hold a patterning device to modulate a radiation beam and a projection optical system arranged to project the modulated radiation beam onto a radiation-sensitive substrate.

12. A system comprising:

an alignment sensor, comprising:

an output to provide radiation from a radiation source onto a target,

a detector configured to receive radiation from the target, and

a control system configured to determine alignment of two or more objects responsive to the received radiation; and

the non-transitory computer program product of claim 9 .

13. The system of claim 12 , further comprising a lithographic apparatus comprising a support structure configured to hold a patterning device to modulate a radiation beam and a projection optical system arranged to project the modulated radiation beam onto a radiation-sensitive substrate.

14. The non-transitory computer program product of claim 9 , wherein the instructions are further configured to, despite a user engaging a particular graphical user interface element, prevent access by the user to the further steps in the measurement design, setup and/or monitoring process for the associated step of the particular graphical user interface element.

15. The non-transitory computer program product of claim 9 , wherein the indicator comprises a color of the graphical user interface element and/or a symbol associated with the graphical user interface element.

16. The non-transitory computer program product of claim 9 , wherein the instructions are further configured to display a graphical user interface element or indicator that represents, or displays or enables display of information regarding, a key performance indicator and/or a guideline.

17. The non-transitory computer program product of claim 9 , wherein the instructions are further configured to use at least three types of indicator, a first displayed indicator indicating that the step in the measurement design, setup and/or monitoring process is not completed and/or that a key performance indicator associated with a step in the measurement design, setup and/or monitoring process has passed a threshold, a second displayed indicator indicating that the step in the measurement design, setup and/or monitoring process is completed and/or that a key performance indicator associated with a step in the measurement design, setup and/or monitoring process has not passed the threshold, and a third displayed indicator indicating that the step in the measurement design, setup and/or monitoring process has not been started.

18. The non-transitory computer program product of claim 9 , wherein the instructions are further configured to display an icon, as the indicator, at least partly overlaying the one or more of the plurality of graphical user elements.
