When defining outbound actions in Pega Customer Decision Hub, two factors are paramount. First, the availability of consent is a legal and ethical prerequisite. Regulations like GDPR require explicit customer opt-in for marketing communications, making consent a critical gatekeeper for any outbound engagement. Second, the customer's preferred communication channel is essential for the action's effectiveness. Engaging customers on their channel of choice (e.g., email vs. SMS) significantly increases the likelihood of a positive response and enhances the customer experience. These two factors determine if you can contact the customer and how you should contact them.

B. The system's processing speed: This is an operational performance metric, not a business or logical factor used to define the substance of an outbound action itself.

D. The frequency of action updates: This pertains to the maintenance and lifecycle management of an action, not the core criteria for its initial definition and targeting.

1. Pega Academy, Pega Customer Decision Hub 24.1 Mission, "Defining customer actions" Module: This module explains that an action represents a business proposal, and its delivery is managed through treatments, which are channel-specific. The choice of channel is a key part of defining how the action is presented to the customer.

2. Pega Documentation, "Engagement policies": "Engagement policies are a set of business rules and practices that your organization can use to ensure that customer engagement is appropriate and empathetic. [...] The policies determine when an action is appropriate for a customer. For example, you can define a policy that prevents the system from sending marketing communications to customers who opted out of receiving them." This directly links the concept of consent (opt-out/opt-in) to the eligibility for an action.

3. Pega Documentation, "Creating an action": When creating an action, the configuration involves defining treatments for various outbound channels (e.g., Email, SMS). The documentation states, "A treatment is a specific way of presenting an action to a customer on a particular channel." This highlights the channel as a fundamental component of the action's definition.
