Workday opens on a home page whose applications lead to tasks and reports. An application is an entry point, not a separate tenant. The global search stays available when you move between pages, and an object's Related Actions menu belongs to the worker, organization or report you selected.
You're using Northstar Fieldworks, a fictional services company. Start by finding the Inbox, worker information and reporting tools. Some menus depend on your security role in a live tenant. A missing task can therefore mean a permissions issue rather than a spelling error. Check the page title and the selected object before entering data; a familiar-looking form can still be attached to the wrong worker.
