Design Input Verification

#1
I'm a relatively new HF engineer, working for a company that manufactures diagnostic devices.

We are creating verification plans for our design inputs, including the two inputs listed below:

Test workflow is suitable for self-completion by users 14 years of age and older.
Users properly understand test results, >98% of the time.


Creating verification plans for some of the hardware/software inputs seem relatively straightforward.

However, I am having some trouble understanding verification for these inputs. Would formative testing, with representative users, be an appropriate method of verification? This is causing some confusion, as it seems very similar to summative testing.

If not, how could I go about verifying these inputs?

Any help or direction is greatly appreciated!

Thanks

Formative testing is appropriate for establishing requirements relating to potential user specifications; summative testing is appropriate for validating systems' design to meet established user specifications.

@Jay_C
I wouldn't refer to these as Design Inputs; more as User Needs.
Hence they belong in Design Validation, not in Design Verification.

Regardless, I'd work on refining these requirements, to improve validability.

Test workflow is suitable for self-completion by users 14 years of age and older.

>>> What are the endpoints for a "suitable" workflow (i.e. what makes one workflow "suitable" while another isn't)? What does a satisfactory "completion" consist of?

Users properly understand test results, >98% of the time.

>>> What are the endpoints of "understand" here (don't forget to consider the 14 years-old)? What makes an understanding "proper" in this case?
