An expression rule deployed to production on January 12, 2022 has form type as a rule input and several other inputs describing the logged in user. Given values for these inputs, the rule returns a set of form instructions for the specific form as applicable to the logged in user. What is the most important action to take with regards to the object description?

An expression rule deployed to production on January 12, 2022 has form type as a rule input and several other inputs describing the logged in user. Given values for these inputs, the rule returns a set of form instructions for the specific form as applicable to the logged in user. What is the most important action to take with regards to the object description?

• A. Set an object description that reads: "returns a set of form instructions to display, given the type of form and characteristics of the logged in user"
• B. Update the deployment date in the description
• C. Describe the data model
• D. Add unit tests

Answer: (A)

Documenting what the rule does is the key purpose of its object description. The rule takes the form type as a rule input along with user-related inputs and returns a set of form instructions tailored to that form and the logged-in user. The best description states this behavior clearly, so future developers understand exactly what the rule produces and under what conditions. That’s why phrasing the description to reflect the output—“returns a set of form instructions to display, given the type of form and characteristics of the logged in user”—is the most precise and helpful option. Other choices don’t serve the same purpose: updating the deployment date doesn’t convey what the rule does, describing the data model focuses on structure rather than behavior, and while unit tests are important, they belong in testing artifacts, not the object description itself.
