Working for a financial organization, over a series of phases I created a process that allowed auditors to view requested product access requests easily.
What I came up with was the following...
A user would go to the request page to select a form
They would then select a form and fill it out (the design of the form was built using InfoPath Designer 2013. Conditional formatting along with some auto population was added to make the form user friendly. Based on a product chosen, a series of fields would display. Also when a user entered their name it would auto pull in their email and job title using the SharePoint User Profile Service.)
The request would then be added in a SharePoint list on the back-end where the admins could easily view the status of the approval etc.
Additionally when the form was submitted an email would be sent to the manager of the user that needing access with information on the request. Right from within Outlook the manager could approval/reject the request.
