Telecommuting
It‘s basically home-working. Telecommuting is an application of information technology whereby
employees can be able to undertake their activities without having to go to the office. For this to happen, the employees will have to be connected to the organization‘s systems. This is facilitated
through the use of communication networks.
Applications:
o Programmers developing a system could use it. A programmer could work on his/her
module from home.
o It could also be used by other office workers who for some reason or the other cannot be
able to make it to the office e.g. due to sickness, leave, or when the office is closed after
working hours (during a weekend or public holiday).
Electronic Data Interchange (EDI)
This refers to the direct computer-to-computer exchange between two organizations of standard
business transaction documents.
EDI could be used to exchange documents such as invoices, bills of lading, or purchase orders
EDI enables speedy and more efficient transactions since it facilitates the quick exchange of
business documents.
Computer conferencing
This facility is similar to e-mail but more expensive in that there is a huge mailbox system where
all persons connected to the system can be able to deposit messages for people to see what other
people have left on the system.
Computer conferencing is appropriate for people undertaking a project so that they can be able to
leave progress reports for each other. Computer conferencing also provides an organizational
wide bulletin board where members can leave messages of general importance.
