When you're satisfied with the project, you can publish to your workflow server and use the URL anywhere you'd like. You can easily publish to the Service Catalog in ProcessManager (the portal used for ServiceDesk) by checking this box during publishing:
Once published to Process Manager, you can move the catalog item around between categories, and control visibility permissions based on who is logged into the portal (or ServiceDesk).
Alternately, you can use the published URL anywhere you want, such as a Sharepoint site, intranet page, email link, etc.
Let me know if this helps, or if I didn't understand your question.
