Problem: Approvers or workflow items such as pre-deal approvals & violations are not always in the office with access to the full ACR system. With round-the-world trading, approvals may be given out of working hours from mobile devices.
General idea: E-mail notifications that relate to new Violations, or Pre-Approval Requests, would have an 'Approve', 'Reject', or any other Transition such as 'Investigate', button that would automatically transition the relevant item in ACR.
Alternatively, clicking on the Violation or Pre-Approval Request link in the e-mail would take the user to a light-weight (mobile) application that would allow the transition to be performed easily. For example, an 'Investigate' or 'Delegate' transition would include an 'Assigned To' field, which would essentially redirect the request to another user (who in turn would receive an e-mail notification).
Security would obviously be a major consideration, e.g. how could a mobile user access a light-weight version of ACR from outside a given domain/network.
