To dynamically update the total cost of a travel reservation as users update each child case component:

B. Configure the Create Case shape to propagate the total cost from each child case to the reservation. Create a declare expression to update the reservation total when the cost of each component changes. This approach leverages the use of a declare expression to automatically update the total cost in the parent case whenever any changes occur in the child cases' costs. It ensures that the reservation total remains accurate and reflective of the current costs associated with the flight, hotel, and vehicle rental bookings.

Procedural processing in application development is used for tasks that follow a specific sequence of steps or require updates based on user actions. It is particularly useful for calculations or updates triggered by user interactions.

• C. A purchase order request page with a summary of items: This scenario involves procedural processing because the application needs to recalculate the total price whenever the customer changes the quantity of an item. This is a direct, sequential update process

Direct Capture of Objectives (DCO) in Pega is designed to enhance the accuracy and speed of application delivery. By capturing requirements directly within the development environment, DCO ensures that there is less miscommunication between business and IT teams, leading to more accurate representations of business requirements in the application. Furthermore, this method speeds up the development process by reducing the need to rework requirements and by allowing for a more agile response to changes.
