                Knowledge Management and Messaging

          Instant Messaging (IM) is the communication tool of the internet-age. The

community that is created by the awareness of other people online, and the real-

time conversation IM enables, makes this type of communication essential for the

global experience. Instant Messaging has reached more than 200 million people

and is forecasted to connect 500 million users by 2006.1 It is a virtually free

communication tool that is able to connect people instantly, creating interactive

possibilities in a multitude of situations. Messaging has become a standard

component of many web-based activities. After examining the foundations of

instant messaging, this report will focus on enterprise applications for knowledge

management.


Foundations of Instant Messaging

          Instant messaging is an Internet protocol (IP)-based application that
          provides convenient communication between people using a variety of
          different device types. The most familiar today is computer-to-computer
          instant text messaging, but IM also can work with mobile devices…and
          can incorporate voice or video.2

          Consumer platforms drove the development of instant messaging,

beginning with the 1996 Mirablis release of ICQ. It was the first tool to feature a

popular, real-time communication application. ICQ (shorthand for “I seek you”) is

still widely used today, though it was acquired by AOL in 1998. Based on this

technology, AOL’s Instant Messenger (AIM) application is currently the most

widely-used instant messaging platform. AIM is a proprietary-protocol system,

like most other instant messaging utilities. This means that, in most cases, both

end users must be on the same platform in order to communicate. While some

utilities do allow users from different platforms to exchange messages, there is

no standard protocol for establishing presence.


          Presence

          Presence is the ability for a user to display to others that he/she is online,

as well as the ability to detect that others are online also. Presence is essential

to the foundation of any instant messaging system.

          With presence, users indicate their status – whether they’re available or
          not…This feature reduces phone tag, enables ad hoc meetings to occur,
          and in general facilitates the sort of electronic communications that might
          naturally occur in person.3

The capability for users to connect with other people, and for other people to

connect with them, is what makes instant messaging the most direct, efficient

form of communication available for a wide variety of interactive tasks. Some

utilities have expanded the idea of presence to include sharing applications in

use, works in progress, and additional location information.


          The Internet Engineering Task Force (IETF) is working on a standard

protocol for IM and Presence. The goal of this work is to enable “an internet-

scale end-user presence awareness, notification, and instant messaging

                                              2
system.”4 This working group is pursuing the SIP (Session Initiation Protocol)

and SIMPLE (SIP for IM and Presence Leveraging Extensions) as the standard

for the industry, and is supported by Microsoft and IBM. An alternate standard

for IM based on Jabber’s XML protocol, XMPP (Extensible Messaging and

Presence Protocol), is being pursued by another IETF working group 5.


          Instant Messaging supports a variety of interactive communication tasks.

It is an informal tool which is primarily used for quick questions and clarifications;

coordination and scheduling; arranging impromptu social meetings; and keeping

in touch with friends and family.6 The success of IM as a communication tool lies

in the fact that it is virtually immediate, flexible, and expressive. In many cases, it

is easier to get a quick response through IM than with a phone call or email

message. According to an ethnographic study reported by Nardi, Whittaker and

Bradner, instant messaging also supports the non-interactive aspects of

communication by providing an easy tool for screening presence, and the option

to delay responding through plausible deniability. These functions give IM users

more control over their interactions than other communication mediums.


Comparing Consumer and Enterprise IM Platforms

          Given the pressure of the knowledge-based economy for just-in-time

processes and real-time decision-making, instant messaging has recently begun

to capture the interest of corporate planners as much as it has the interest of

teenagers. “The Gartner Group predicts that by 2004, sixty percent of real-time

communication…will be driven by IM technology.”7 There are essentially three

levels of IM platforms available today: consumer (usually free) systems,

enterprise (usually more secure) systems, and hybrid systems that try to bridge

features of both. The consumer-level platforms include AIM, MSN and Yahoo

Messenger, and ICQ. These utilities are proprietary protocol systems, requiring

each end-user to be on the same system, and are not considered secure.


          IM applications for business allow the company to establish much more

control over the communication function. Systems targeted for business use

include Lotus Sametime (soon to be Lotus Instant Messaging), Microsoft

Exchange, and Jabber. The current trend in Enterprise IM applications is for

companies to manage their own user namespace. This control allows a business

to integrate directories; ensure message encryption for each end-user; and

provide auditing/reporting mechanisms for more secure communication than is

currently available through the consumer IM platforms.8


          Hybrid systems claim to add increased security and functionality to the

publicly-available IM utilities while exhibiting presence across platforms. One

hybrid system is IM Age’s IM-Policy Manager, which is purported to be a “low-

cost security tool that allows organizations to safeguard IM over public

networks.”9 The company promises “seamless integration” with multiple

platforms, international support, and encryption. The Yankee Group recently

published a comparison of the advantages and disadvantages of each type of

instant messaging system.

          Other Instant Messaging Applications

          Internet Relay Chat (IRC) is “a major real-time textual group messaging

system.”11 IRC conversations, like all group-messages, take place on channels –

commonly known as chat rooms. The volume and arbitrary identification of

participants makes it difficult to connect with interesting/relevant conversation.

Butterfly is a software agent that “samples the content of all the [IRC] channels,

and makes recommendations using a keyword-based model of interest.”12 The

agent allows users to designate three levels of interest in a topic – normal, great,

and negative.


          There are a growing number of utilities that offer cross-platform presence

and messaging functions. Trillian is a notable example of this type of application.

The freeware version of the application has been gaining popularity over the last

year, and Trillian Pro, released last fall, has also received a lot of attention. The

Pro version, which costs $25 and has a yearly user fee, is customizable and

skinnable. A software development kit is available for third party developers to

create plug-ins for the program. Plug-ins already available include email

integration, stock ticker and news headlines, and a browser. While Trillian allows

users to IM across platforms, the company has not entered into formal access

agreements with the other IM companies, meaning that communications are not

guaranteed to be operational – though there have been few disruptions thus far.


Enterprise Applications for Instant Messaging

          The Gartner Group estimates that seventy percent of companies will use

IM by the end of 2003, and that half of all interactions between companies and

their customers will involve IM by 2005.13 Therefore, IT departments should be

more active in creating corporate policies for instant messaging.

          It took more than ten years before enterprises recognized and effectively
          addressed problems of (e-mail) security, reliability, and business policy.
          Enterprises must pay proper attention to IM usage now, lest they repeat
          the painful lessons taught by e-mail.14

Companies should be focused on redirecting IM usage from the personal gossip

enabled by consumer IM tools, towards more collaborative uses through

enterprise IM applications.


          There is a broad consensus that instant messaging is an integral

component of web-based applications for business and personal communication.

“[IM] is not restricted to customer service. It can be used for scheduling,

conferring among colleagues, and communicating with professionals outside the

company – any area where instant communication and response are

desirable.”15 The ease of a virtually real-time, virtually free tool for connecting

individuals and systems is the chief factor in its ubiquity. In a recent survey by

the Osterman Research Group, ninety-three percent of one hundred and two

companies with more than one thousand employees say that they are currently

using instant messaging or expect to use IM on their networks in the near future.

Thirty-three percent of the survey respondents reported that their companies had

chosen an IM standard; and twenty-eight percent currently block IM traffic.16


       Business IM systems offer secure communications, usually coupled with

other peer-to-peer applications. Enterprise features take instant messaging from

being simply a platform for casual chatting, to a powerful tool for knowledge

management. In a recent report, Instant Messaging for Business, five key

considerations are delineated. Three issues are related to the support required

for system operations, client platforms, server platforms, and directories. If the

IM system is expected to connect customers with the enterprise system, then

cross-functionality with consumer IM platforms will be important. Enterprise

platforms should also log and archive IM chats. This feature is key to the use of

IM for many businesses. Under current federal regulations for both financial and

health-related companies, communications between client and provider should

be secure, confidential, and documented. Enterprise IM applications fall under

the same guidelines that currently require companies to archive email and phone

records.

          Jabber

          Jabber has established itself as a corporate IM system. Jabber is an open

source, XML-based protocol that allows for distributed, yet private, namespace

and single-point conversation management. In addition to indicating

online/offline presence, Jabber can also provide information about location,

applications in use, and other contextual details. The Jabber system also allows

for IM conversations to be centrally-logged. Since Jabber can support peer-to-

peer, peer-to-application, and application-to-application communication, in real-

time and asynchronously, as well as communicate with users on multiple

platforms, it has become an attractive enterprise IM platform.


Instant Messaging for Knowledge Management

          The act of connecting with someone else through simple protocols, across

a variety of devices and software applications, is revolutionizing communication

in the information age. A 2002 report by the Meta Group lists nine important

trends in the future of instant messaging. Several of these are knowledge

management functions for IM including: archiving, presence integration with

email and other applications, mobile support, and added functionality for file

sharing, videoconferencing and whiteboarding.18 Archived IM chats allow the

participants to accurately retrieve important details from a transcript at any time,

just as people involved in a collaborative project would save email for later

reference. Through presence, IM helps to create a sense of community that is

essential to building the relationships required for sharing knowledge. IM offers a

more efficient alternative to traditional telephone calls, and with the added

functionality of many enterprise platforms, is more cost-effective than current

web-conferencing applications. Instant communication is truly becoming the

ubiquitous tool for business in the twenty-first century.


          Enterprise applications that combine the functionality of IM with other

document and file-sharing features will provide companies with a powerful new

tool for fostering communication, information sharing, and knowledge

management.

          Messaging tools and affinity communities [direct file-sharing groups] can
          open up intellectual property and data that are otherwise hidden in
          departmental offices and servers. Now that knowledge management is
          such a big priority for so many companies (80 percent of the world’s

          biggest are dabbling in KM, according to PricewaterhouseCoopers and the
          Conference Board), businesses can reap benefits from P2P that they don’t
          care to measure in dollars.19

The communication that is enabled by instant messaging is a key component of

knowledge management. While current IM platforms are still working to define

features for business applications, workers have already brought IM into

corporate use. The challenge facing knowledge managers is to redirect IM

usage and capabilities to the benefit of clients, employees, and the enterprise.
