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 Tool
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.
