Decisions, Decisions, Decisions

• Question How do you decide?

44
Decisions, Decisions, Decisions

• Length, format, duration
• Push vs. pull requirements
• Synchronous or asynchronous?
• Whats the author - audience pattern?
• Is the audience well-defined or a diverse,
  unknown, or large audience?
• IT Restrictions?

45
Decisions

• Whats the nature of the message?
• The length of the communication is important.
• For short, simple, timely, timely messages
  microblogging, blogs, and emails may be best.
• Longer, more in depth, permanent communications
  are better handled in more extensive repositories
  of information such as wikis.
• The format of the content, such as text, audio,
  graphics, photo, video, will also impact the
  selection of the communication approach.
• The intended lifespan of the information is
  important.

46
Decisions

• Push vs. pull requirements
• Is it better to push the content out to the
  audience, such as in email, or to pull them to a
  website, such as a blog?
• Synchronous or asynchronous?
• Some tools are better if everyone is online at
  the same time while others are better when a
  delay is OK.

47
Decisions

• Whats the author - audience pattern?
• One author to one reader/listener (use email,
  instant messaging, or text messages)
• One author to many (use email, blogs,
  microblogs, podcasts, videos)
• Many authors to one (use polling, online surveys,
  RSS feeds)
• Many authors to many (use wikis, group email
  lists, forums)

48
Decisions

• Is the audience well-defined or a diverse,
  unknown, or large audience?
• If the audience is well-defined, using email is
  effective. However, if the audience membership is
  not known, blogs and listserves are more
  appropriate.
• IT Restrictions?
• Restricted access to some technologies due to
  bandwidth limitations, security issues, and
  fraud, waster, or abuse will affect the selection
  of a tool.

49
Issues

• Validity of the information
• Personal time to read/watch the communications
• How to filter/decide whats important, credible?
• Lurking vs. participation
