Explanation:
Fixed-price contracts. This category of contracts involves setting a fixed total price for a defined product, service, or result to be provided. Fixed-price contracts may also incorporate financial incentives for achieving or exceeding selected project objectives, such as schedule delivery dates, cost and technical performance, or anything that can be quantified and subsequently measured. Sellers under fixed-price contracts are legally obligated to complete such contracts, with possible financial damages if they do not.
Under the fixed-price arrangement, buyers need to precisely specify the product or services being procured. Changes in scope may be accommodated, but generally with an increase in contract price.

10.1.2.3 Communication Models
The communication models used to facilitate communications and the exchange of information may vary from project to project and also within different stages of the same project. [..]. Medium is the technology medium and includes the mode of communication while noise includes any interference or barriers that might compromise the delivery of the message. The sequence of steps in a basic communication model is:
Encode. Thoughts or ideas are translated (encoded) into language by the sender.

Transmit Message. This information is then sent by the sender using communication channel (medium).

The transmission of this message may be compromised by various factors (e.g., distance, unfamiliar technology, inadequate infrastructure, cultural difference, and lack of background information). These factors are collectively termed as noise.
Decode. The message is translated by the receiver back into meaningful thoughts or ideas.

Acknowledge. Upon receipt of a message, the receiver may signal (acknowledge) receipt of the message

but this does not necessarily mean agreement with or comprehension of the message.
Feedback/Response. When the received message has been decoded and understood, the receiver

encodes thoughts and ideas into a message and then transmits this message to the original sender.
Process: 10.2 Manage Communications
Definition: The process of creating, collecting, distributing, storing, retrieving and the ultimate disposition of project information in accordance with the communications management plan.

Explanation:
* Scatter diagrams, plot ordered pairs (X, Y) and are sometimes called correlation charts because they seek to explain a change in the dependent variable, Y, in relationship to a change observed in the corresponding independent variable,
X. The direction of correlation may be proportional (positive correlation), inverse (negative correlation), or a pattern of correlation may not exist (zero correlation). If correlation can be established, a regression line can be calculated and used to estimate how a change to the independent variable will influence the value of the dependent variable.
