Obviously, there is the issue of what delivery system you are using. For example, if you are using Genesys CTI for call delivery, then Genesys' own WfM software is the one to choose - here, the data comes from the Genesys environment, not from the PBX, where all other WfM systems need to be integrated, adding cost and data corruption. If you have a Voice over IP environment, look at what data the IP stream provides, and how you can use it in the WfM application.
In essence, WfM software is reliant on quality of data - garbage in, garbage out. |
