According to the PMBOK Guide and the Standard for Project Management, communication methods are categorized based on how information is shared and accessed.
* Pull Communication: This method is used for very large volumes of information or for very large audiences. It requires the recipients to access the content at their own discretion. Examples include intranet sites, e-learning, knowledge repositories (like a lessons learned database), and bulletin boards.
The defining characteristic is that the " sender " places the information in a central location, and the " receiver " must take action to " pull " the information.
* Push Communication: This involves sending information directly to specific recipients who need to receive it. This ensures that the information is distributed but does not guarantee it reached or was understood by the target audience. Examples include letters, memos, emails, and press releases.
* Interactive Communication: This is a multidimensional exchange of information in real-time between two or more parties. Examples include meetings, phone calls, and video conferencing.
Analysis of other options:
* D. Stakeholder communication: This is a general term describing the process of sharing information with stakeholders, but it is not a specific communication method defined by PMI ' s technical standards (Interactive, Push, and Pull).
By implementing a lessons learned database, the project manager is contributing to Organizational Process Assets (OPAs). Using a Pull method is the most efficient way to manage such a database, as it allows future project managers and team members to search for and retrieve relevant knowledge only when they need it.
