10.1.2.4 Communication Methods
There are several communication methods that are used to share information among project stakeholders.
These methods are broadly classifed as follows:
Interactive communication. Between two or more parties performing a multidirectional exchange of

information. It is the most effcient way to ensure a common understanding by all participants on specified topics, and includes meetings, phone calls, instant messaging, video conferencing, etc.
Push communication. Sent to specific recipients who need to receive the information. This ensures that the

information is distributed but does not ensure that it actually reached or was understood by the intended audience. Push communications include letters, memos, reports, emails, faxes, voice mails, blogs, press releases, etc.
Pull communication. Used for very large volumes of information, or for very large audiences, and requires

the recipients to access the communication content at their own discretion. These methods include intranet sites, e-learning, lessons learned databases, knowledge repositories, etc.
The choices of communication methods that are used for a project may need to be discussed and agreed upon by the project stakeholders based on communication requirements; cost and time constraints; and familiarity and availability of the required tools and resources that may be applicable to the communications process.
