Asynchronous Tools
Asynchronous tools enable communication
and collaboration over a period of time through a "different time
different place" mode. These tools allow people to connect together at
each person's own convenience and own schedule. Asynchronous tools are useful
for sustaining dialogue and collaboration over a period of time and providing
people with resources and information that are instantly accessible, day or
night.
Asynchronous tools possess the
advantage of being able to involve people from multiple time zones. In
addition, asynchronous tools are helpful in capturing the history of the
interactions of a group, allowing for collective knowledge to be more easily shared
and distributed. The primary drawback of asynchronous technologies is that they
require some discipline to use when used for ongoing communities of practice
(e.g., people typically must take the initiative to "login" to
participate) and they may feel "impersonal" to those who prefer
higher-touch synchronous technologies.
Synchronous tools enable real-time
communication and collaboration in a "same time-different place"
mode. These tools allow people to connect at a single point in time, at the
same time.
Synchronous tools possess the advantage of
being able to engage people instantly and at the same point in time. The
primary drawback of synchronous tools is that, by definition, they require
same-time participation -different time zones and conflicting schedules can
create communication challenges. In addition, they tend to be costly and may
require significant bandwidth to be efficient.
