When evaluating Access Controls, ServiceNow searches and evaluates:
* From the most specific match to the most generic match. This is the correct answer because ServiceNow follows a top-down approach when evaluating Access Control (ACL) rules, which are used to restrict the access to the data and functionality of the ServiceNow platform based on the user's roles and conditions. ServiceNow starts with the most specific match, which is the field-level ACL rule, then moves to the table-level ACL rule, and finally to the global or * ACL rule. ServiceNow grants access if any of the ACL rules evaluates to true, and denies access if all of the ACL rules evaluate to false.
The following are not correct descriptions of how ServiceNow searches and evaluates Access Controls:
* Only for matches on the current table. This is not correct because ServiceNow does not only look for matches on the current table, but also on the parent tables and the global or * table. For example, if there is no ACL rule for the incident table, ServiceNow will look for an ACL rule for the task table, which is the parent table of the incident table, and then for the global or * table, which is the parent table of all tables.
* Only for matches on the current field. This is not correct because ServiceNow does not only look for matches on the current field, but also on the table that contains the field and the global or * table. For example, if there is no ACL rule for the short_description field on the incident table, ServiceNow will look for an ACL rule for the incident table, and then for the global or * table.
* From the most generic match to the most specific match. This is not correct because ServiceNow does not follow a bottom-up approach when evaluating Access Controls, but a top-down approach, as explained above. References: Access Control Rules, ACL Evaluation Order

The application development plan is a document that outlines the scope, objectives, deliverables, and timeline of a software project1. It should include the following business requirements and processes:
Data input/output: This describes what data is needed for the application to function, how the data is collected, stored, processed, and displayed, and what outputs are generated by the application2.
Business problem: This defines the problem or opportunity that the application aims to address, the current situation, the desired outcome, and the benefits of the solution3.
Process steps: This details the steps involved in the application development lifecycle, such as planning, designing, testing, deploying, and maintaining the application4.
Users/stakeholders: This identifies the people who will use, benefit from, or influence the application, their roles, responsibilities, and expectations, and how they will be involved in the project5.

Business Rules run server-side, so the correct APIs come from the GlideSystem object (gs) rather than client- side objects like g_form. In server-side scripting, the platform provides a standard way to retrieve the currently logged-in user's identity. The method gs.getUserID() returns the sys_id of the user associated with the current session. This is commonly used in Business Rules for auditing logic, conditional processing, field stamping (for example, setting a custom "last processed by" field), or enforcing business rules based on user identity. The g_form object is a client-side API available in Client Scripts and UI Policies, so any option using g_form is invalid in a Business Rule context. Likewise, gs.getUserSysID() is not the documented method name for this purpose. Using the correct server-side API ensures the script executes reliably regardless of UI context (classic UI, workspace, mobile), because it relies on the session and not on the form rendering layer.
