The project delivery leader is responsible for managing the project scope, timeline, budget, and quality. They also communicate with the stakeholders and sponsors to align expectations and resolve issues. If the scope of the project exceeds the original estimates, the project delivery leader should be contacted to verify the project plan and manage expectations for the release schedule.

To ensure that valid data is used in a case, you need to make sure that the data fits the business logic and the data is the correct field type. The data fits the business logic means that the data conforms to the rules and constraints that define the business problem and solution. For example, you can use validations, calculations, and dependencies to ensure that the data fits the business logic. The data is the correct field type means that the data matches the expected format and structure of the field that stores or displays it. For example, you can use different types of fields and controls to ensure that the data is the correct field type.

To indicate the progress of a case towards resolution, you need to update the case status on the appropriate steps. The case status reflects the current state of a case and helps users track its progress. You can use standard statuses such as New, Pending-Approval, or Resolved-Completed, or define custom statuses for your application. The other options are either incorrect or irrelevant for this requirement. Reference: https://docs-previous.pega.com/case-management/87/updating-case-status

You can use a list or an interactive chart to present insight data on the Explore Data landing page. A list displays the data in a tabular format, while an interactive chart displays the data in a graphical format, such as a pie chart or a bar chart. You can also filter, sort, group, and drill down the data in both types of visualizations.
