The following are the features of SAP Build Work Zone that enable users to create and consume content:
UI embedding: This feature allows users to embed UI elements such as UI Integration Cards, URL apps, SAPUI5 apps, and WebDynpro ABAP apps into SAP Build Work Zone pages and workspaces123. UI embedding enables users to access various applications and services from a single interface and create personalized and engaging experiences.
Guided Experience: This feature allows users to create and consume interactive and step-by-step guides that help them complete tasks and workflows in SAP Build Work Zone and other applications12. Guided Experience enables users to learn and perform complex processes with ease and efficiency.
Content Package: This feature allows users to create and consume reusable and modular content bundles that contain UI elements, guided experiences, and workspace templates124. Content Package enables users to share and distribute content across different SAP Build Work Zone instances and environments.

The feed widget setting that is used on the home page level to show all public feed updates is Global. The feed widget is a type of widget that embeds a feed in an external web page. The feed widget builder allows users to create and customize feed widgets using various settings, such as the feed source, the feed type, the feed layout, and the feed filter. The feed source setting determines which feed is displayed in the widget. There are four options for the feed source setting: Public, Global, Home, and Company. The Public option displays the public feed of the site, which includes all public updates from all workspaces and members. The Global option displays the global feed of the site, which includes all public and private updates from all workspaces and members that the user has access to. The Home option displays the home feed of the user, which includes all updates that are relevant to the user, such as updates from their workspaces, followed members, and @mentions. The Company option displays the company feed of the user, which includes all updates from the user's company, such as updates from their colleagues, managers, and subordinates. The feed widget setting that is used on the home page level to show all public feed updates is Global, because it shows all the updates that the user can see on the site, regardless of their workspace or member affiliation. The other options are either too restrictive (Home and Company) or too broad (Public) for the home page level. Reference:

The tasks of the cutover plan are executed in the Deploy phase of SAP Activate. The Deploy phase covers the implementation of the target SAP solution into a Productive (Go Live) state for use by the target business users; this is referred to as the Project Cutover1. The cutover plan describes all required tasks that must be performed before the go-live and needs to cover the following tracks: Infrastructure, System Design, Security, Data, and Training2. The cutover plan is refined and updated during or after the cutover simulation, which is also part of the Deploy phase1. The Deploy phase ends with the successful go-live of the SAP solution and the transition to the Run phase3.

A role collection is a set of roles that are required to access an application or a service in SAP BTP. A role is a granular authorization that defines what actions a user can perform on a specific resource. A user must be assigned or mapped to a role collection at the SAP BTP subaccount level to access an application that is deployed to SAP BTP (Cloud Foundry). A group is a collection of users that share the same attributes, such as department or location. A user list is a way to manage users in the SAP BTP cockpit. Neither of these are related to the access control of applications or services in SAP BTP. Reference:

Application tiles are created and configured in the Content Manager, which is a tool located in the Site Manager of SAP Build Work Zone. The Content Manager includes various editors that you can use to configure apps, groups, roles, and catalogs. Once configured, the app appears as a tile in the Applications page of your site - a single page that acts as an embedded launchpad. You can also implement custom visualizations for your app tiles, such as Static App Launcher and Dynamic App Launcher. Reference:
