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.

9.1.1.2 Activity Resource Requirements
Described in Section 6.4.3.1. Human resource planning uses activity resource requirements to determine the human resource needs for the project. The preliminary requirements regarding the required project team members and their competencies are progressively elaborated as part of the Plan Human Resource Management process.
6.4.3.1 Activity Resource Requirements
Activity resource requirements identify the types and quantities of resources required for each activity in a work package. These requirements then can be aggregated to determine the estimated resources for each work package and each work period. The amount of detail and the level of specificity of the resource requirement descriptions can vary by application area. The resource requirements documentation for each activity can include the basis of estimate for each resource, as well as the assumptions that were made in determining which types of resources are applied, their availability, and what quantities are used.
Process: 9.1 Plan Human Resource Management
Definition: The process of identifying and documenting project roles, responsibilities, required skills, reporting relationships, and creating a staffing management plan.
Key Benefit: The key benefit of this process is that it establishes project roles and responsibilities, project organization charts, and the staffing management plan including the timetable for staff acquisition and release.

Explanation:
7.2.3.1 Activity Cost Estimates
Activity cost estimates are quantitative assessments of the probable costs required to complete project work.
Cost estimates can be presented in summary form or in detail. Costs are estimated for all resources that are applied to the activity cost estimate. This includes, but is not limited to, direct labor, materials, equipment, services, facilities, information technology, and special categories such as cost of financing (including interest charges), an inflation allowance, exchange rates, or a cost contingency reserve. Indirect costs, if they are included in the project estimate, can be included at the activity level or at higher levels.
Process: 12.1 Plan Procurement Management
Definition: The process of documenting project procurement decisions, specifying the approach, and identifying potential sellers.
Key Benefit: The key benefit of this process is that it determines whether to acquire outside support, and if so, what to acquire, how to acquire it, how much is needed, and when to acquire it.
