Use Case Number

Otherhm2.pm13.4

Brief Description

In data collections forms, it is possible that the value of a CDE is derived from the values of other CDEs.  For example, an Address CDE may be derived from a set of CDEs for Street, ZipCode, City, and State.  A derived CDE is often combined with the non-editable flag so that, when presented in a form, the user does not directly edit the value because it is composed from other values.

Actor(s) for this particular use case

Metadata Specialist, Clinical Researcher

Pre-condition
The state of the system before the user interacts with it

None.

Post condition
The state of the system after the user interacts with it

Data is collected for a derived CDEs

Steps to take
The step-by-step description of how users will interact with the system to achieve a specific business goal or function

1. The Metadata Specialist selects and defines a set of CDEs for use within a data collection form
2. The Metadata Specialist selects a CDE that is derivedcan see which CDEs are derived when building the form.
3. The Metadata Specialist set isEdtiable to either "Yes" or "No" as needed.
4. The Metadata Specialist deploys the form for data collection.
5. The Clinical Researcher captures data using the form
6. Once the CDEs that are being used to derive a value are filled in, the derived CDE value can be evaluated.

Alternate Flow
Things which would prevent the normal flow of the use case

1. If the isEditable is set to "Yes", the researcher can fill a value.
2. If the isEditable is set to "No", the researcher cannot fill in a value.

Priority
The priority of implementing the use case: High, Medium or Low

High.
