The primary benefit or output derived from setting targeted capability levels and performing a capability-level gap analysis for selected processes is the identification of process improvement opportunities, according to the official COBIT 2019 Study Manual from ISACA. This gap analysis can help to identify areas where processes are not meeting their desired capability levels and can provide insight into how processes can be improved to meet their desired levels. This can help to increase efficiency and reduce costs.

According to ISACA COBIT 2019, the key change enablement task that must be completed during the driver identification phase of an IT initiative is to "Identify the business and governance drivers." This task is important because it helps to determine the motivations and reasons for change, which can then be used to inform the development of the initiative and ensure that it is aligned with the needs and goals of the enterprise. This information can also help to prioritize and scope the initiative and to develop a business case for the changes needed.
