The Landing Page is the starting point from which you can use:
App Designer - Design your process
My Tasks - View your task inbox or queue
Profile management / Identity management - Manage user and group capabilities
Analytics - Generate reports on process performance
Depending on the capabilities of your account you may or may not get access to the App Designer or Analytics.
Profile management will appear will appear for you only if you are a user. This is where you manage your personal information. If you have administrator capabilities, then Profile management will be displayed as Identity management. Use this tile to access your profile page as well as to manage user, group, and capability management pages for your tenant or the whole system.
You can click on the Alfresco Process Services logo at any time to return to your landing page.
Your landing page is dynamic, and new tiles will appear when you create new process apps in the App Designer and deploy them in the Task App.
You'll also see a list of shortcuts for tasks you might want to do next.
All pages display the App Navigator icon in the far-right corner of the header. It provides useful 1-click shortcuts to various parts of the app. You can navigate instantly to all your process models, tasks, processes, stencils, forms, decision tables, quickly start any process, view the tasks and processes for a published and deployed app, or view and change your profile. As you deploy process apps, the App Navigator will also show shortcuts for the newly created process apps.
