Can you easily report on your staff's activity within your CRM system and overlay it with call data from your phone system?
To build an answer you first have to determine what efficiency means to you. There are many indicators that could be used and your organisation will likely want a combination of those most relevant to you.
ProvenWorks are experienced in building systems to answer all of these questions for a variety of different businesses. Contact us to discuss how we can help you do the same.

Telephone Systems (PBX) generally output call logging data in a format called SMDR see http://en.wikipedia.org/wiki/Call_detail_record. ProvenWorks have experience of writing Windows Service applications that connect to PBX call logging interfaces and record the data to a database for reporting, Contact Us for more information.
ProvenWorks can build a bespoke Management Reporting Platform which takes your telephone system data, overlays it with your CRM data and presents it in an easy-to-read fashion which can then be re-run at the push of a button
