Open standards do not eliminate the need for systems integration. I've never once seen a truly ready-to-run product, one that didn't need some kind of customization,” says Mark Webster, VP of sales for Bell Atlantic Call Center Services (Bell Atlantic CCS; Dallas, TX).

In the parallel web-enabled messaging universe, where the goal is to give away as much service to as many people as fast as possible, eVoice (Menlo Park, CA – 650-330-3700, www.evoice.com) has come up with a great consumer lure: They will answer your existing home phone for free. They will record messages on no-answer or busy signals. Unplug the answering machine, pay your RBOC five-six-seven dollars less per month. Unlike all the messaging.coms I've seen so far, eVoice is not asking subscribers to use a new phone number to get into their network. If your line is busy on the Internet, eVoice will let you know someone is calling and give you caller ID.

eVoice answers your own phone with your own greeting. Dial your own number and hit * to retrieve your messages, just like telco voicemail. Or, like all the Webleys and Porticos and visittalk.coms and onebox.coms, retrieve your messages off a website using RealAudio, anywhere you can get Internet access. Or dial a local number or an 800 number.

eVoice doesn't need to give out DID numbers to every subscriber, because they already know where and who you are: They've worked out their own SS7 signaling integration with carriers' infrastructure, and co-located their own IP-connected, Dialogic-and-NT-based platforms in COs across the U.S. and coming up, around the world. We combine the best of the telecom infrastructure with the low cost of the Internet backbone,” says Bruce Crair, president. It's basically VPN and the Internet to connect all of our servers across the country.” Since it's all asynchronous communication, voice quality does not suffer from packetization.

It's taken them 18 months to work all these telco arrangements and SS7 variants out. They're certainly hoping that consumers appreciate the difference, because they need lots of subscribers to make money on an advertising business model.

Forecasting application features

An important aspect to note is that best-of-breed” forecasting applications are designed to be used across a diverse set of industries. While many forecasting applications have a good base of time-series forecasting capabilities, only the leading-edge, best-of-breed ones are full-featured enough to cover the needs of a wide variety of forecasting environments.

These full-featured packages meet most of the following building-block requirements needed to support the majority of forecast processes:

Full-featured applications support forecasting processes that first start with a baseline forecast to which marketing/sales intelligence is applied. The baseline typically incorporates all known, quantifiable impacts on future demand and is sometimes called the system-generated” forecast because it is usually automatically generated by the application.

For mature products with long histories of demand, it is usually developed by a best-fit method, which determines a standard time-series method that best explains historical demand variations. Special forecasting methods, however, are needed to develop a baseline forecast for non-mature products.
