How to Open the Kimono Safely
Hossein Eslambolchi, ATT CIO and CTO, discusses how ATT has opened their network to customers - very much an example of deperimeterization drive by business.
In addition to designing a data services layer and an application layer (which runs Web services), AT&T has a separate presentation and security layer. Eslambolchi and his team then further divided things into zones.
"You have to build a security infrastructure around the network, with clearly segregated security by application, by port, by customer, by service," says Eslambolchi. "You cannot take security lightly. It's not just a connection to the Internet—it's a connection to the AT&T network."
Although few ... are willing to discuss the specifics of how they address security, they all agree that it's a critical success factor when you're allowing outsiders access to internal systems—making a more open customer access system possible and profitable.
Nice Doing Business with You
This series on enterprise value awards focuses on the value of a self-service model for customers which increases customer loyalty and retention.
So whenever you can remove a human from the equation in a routine business process, you reduce the risk of error—and generally increase efficiency and reduce transaction costs to boot. "The trend is toward removing the bottleneck of human intervention from processes," says Esteban Kolsky, a Gartner research director who focuses on customer service and CRM.
Four of this year's Enterprise Value Award winners ... has given customers access to their back-end systems, whether through online portals or through direct links to customers' own systems. By making themselves easier to do business with, they've made customers happier—and gotten more of their business.
If eliminating the need for human involvement on one side of the equation is good for routine transactions, removing humans on both sides of the equation can yield even greater efficiencies. ... three of the Enterprise Value Award honorees are taking that extra step of allowing their customers' systems to link directly into theirs, yielding efficiencies for company and customer alike.
Expect business value to trump security - the smart businesses will always try to identify risk and then manage it. Barnett offers a very smart analogy between business and security:
Pol-mil refers to political-military, and it's a term of art to remind the economic world that security is the "everything else" they (the business types) tend to forget, just like the Pentagon tends to ignore the "everything else" beyond war.
This also can be applied to many security practitioners today, replace "the Pentagon" with "information security". No one wants to be a casualty in a war...
The other aspect we need to remember when 'eliminating human involvement' is that not only are we reducing errors and increasing speed we are also at risk of increasing risk - do we just pay whatever bill is sent our way? Or do we look at those bills to make sure they are right?
Ready, Aim, Fire!
Hardly politically correct, Michael Schrage gives us a dose of what many of us miss:
Nothing boosts morale or heightens concentration quite like the public firing of an individual who everyone knows is a persistent obstacle to discipline, collaboration, quality and ethics during an implementation. That these individuals have been able to flourish in your organization is a reproof to all your posturing about IT excellence and professionalism.
The culture was very polite and non-confrontational. Too polite. It frequently took weeks to get to the guts of a process design conflict. My professional opinion was that these delays were unhealthy and unproductive.
Even ditching 'star performers' can lead to overall improvements in productivity and employee morale. There are also cultures however that are doomed to extinction.
The Future of Wireless according to CIO and Business 2.0
New Way of Wireless
Cellular technologies are slowly increasing bandwidth from a painfully slow 30 kbps to an improved 300 kbps. But even that is dwarfed by new technologies and 'fixed based' systems.
Step out of the current network schemes, and you'll find even more options, such as Flash OFDM, a proprietary technology from Flarion Technologies that the company claims can offer real-world speeds of up to 1Mbps for users in motion and greater than 1Mbps for those not moving.
Based on the recently approved IEEE 802.16d standard, fixed WiMax has received a lot of attention lately as a wireless replacement for DSL, cable or T1 lines.
The technology provides connection speeds up to 10Mbps over five miles, says Jim Johnson, Intel's vice president of wireless networking, who expects to see technology trials this spring. "WiMax will stand out as a fixed wireless broadband solution."
And the IEEE 802.16e standard that supports mobile WiMax won't be finalized until 2006, so wireless carriers are also being cautious.
55% of large U.S. businesses will deploy a wireless wide-area data solution by mid-2006. (YANKEE GROUP)
The Road Map to Broadband Nation
For all of the moaning that our national high-speed infrastructure is being hopelessly damaged by the Bush administration, this reveals a more accurate picture:
Half of all U.S. households will have broadband access by next year, with the portion climbing to 75 percent by 2010. Not surprisingly, the quantity of data being pumped into homes is also increasing. Next-generation DSL and passive optical-networking technologies will usher in data rates in the range of 24 megabits per second -- nearly six times quicker than today's fastest cable modems. Thanks to new DSL chip designs, network speeds will climb to 100 Mbps by next year.
Some terms from this article are nicely defined:
3G (3rd generation cellular networks) Carrying information at up to 1 mbps - will be readily available by 2007
4G (4th generation cellular networks) Expect up to 40 mbps - enough to watch a DVD quality movie - still in development
BPL (Broadband over Power Lines) High speed information networks carried over our electrical grid - telcos and cable companies gotta be looking over their shoulder on this one
Cable broadband - 60% of broadband users have this - I get 4 mbps at home today
DSL (Digital Subscriber Line) Currently in the 300 kbps range - but newer versions promise up to 50 mbps over existing copper and extended distances.
Fiber Optic - Much faster ( 1 gbps) and much more expensive
Fixed Base Wireless - High speed coverage (10 - 100 mbps) over miles of area - but requires the receiving devices to stay in a fixed location. Think of this option like putting up a dish receiver for TV service. (WiMax)
Wi-Fi - Wireless Fidelity offer short range (hundred of meters) high speed wireless networking up to 100 mbps - what you get at StarBucks or the airport
UWB - Ultra Wide Band - Initially seen as a high speed 'system cable' replacement technology (replaces USB, BlueTooth and even that bulky monitor cable) but offers capabilities to reach very long distances at very high transmission rates (if the HAM radio operators don't have their way).
