The enterprise strategy archetype is a design factor that describes how an enterprise uses information and technology to achieve its goals and objectives. There are six enterprise strategy archetypes defined in COBIT
2019: growth/acquisition; operational excellence; customer intimacy; product leadership; data-driven; innovation-driven. Each archetype has different implications for the governance and management of information and technology in terms of focus areas, processes, practices, roles, structures, and metrics. One of the important components for an enterprise strategy archetype of growth/acquisition is support for the portfolio management role with an investment office. Growth/acquisition is a strategy archetype that emphasizes expanding market share, revenue, customer base, or product range through organic growth or acquisition of other businesses or assets. This strategy archetype requires effective portfolio management of information and technology investments and initiatives that support business growth or acquisition objectives.
Portfolio management involves selecting, prioritizing, balancing, monitoring, evaluating, and optimizing information and technology investments and initiatives based on their alignment with business strategy, value delivery potential, risk exposure, resource availability, interdependencies, etc. Portfolio management also involves ensuring that information and technology investments and initiatives are integrated with business processes, systems, structures, culture, etc., especially in case of mergers or acquisitions. Support for the portfolio management role with an investment office means providing a dedicated function or unit that assists the portfolio manager in performing portfolio management activities such as planning, analysis, decision making, reporting, etc., as well as providing guidance, tools, methods, frameworks, standards, best practices etc., for portfolio management5 References: 5: COBIT 2019 Design Guide: page 35-36 : COBIT 2019 Process Reference Guide: page 59-61

Explanation
Enterprise strategy cascades to enterprise goals within the COBIT goals cascade. The COBIT goals cascade is a mechanism that helps enterprises to align their governance objectives with their stakeholder needs. It consists of four levels: stakeholder drivers, enterprise goals, alignment goals, and governance and management objectives. Enterprise strategy is the high-level direction and guidance that defines how the enterprise will achieve its vision and mission. Enterprise goals are the specific targets or outcomes that the enterprise sets to achieve its vision and mission. Enterprise strategy cascades to enterprise goals through a process of analysis, prioritization, and validation.12 References: COBIT 2019 Framework: Introduction and Methodology, COBIT

Explanation
The COBIT framework is designed to meet the I&T goals for the entire enterprise. The COBIT framework is a comprehensive governance and management framework for information and technology that helps enterprises to achieve their goals and create value. The COBIT framework consists of four core publications:
COBIT 2019 Framework: Introduction and Methodology; COBIT 2019 Framework: Governance System; COBIT 2019 Framework: Governance and Management Objectives; COBIT 2019 Design Guide: Designing an Information and Technology Governance Solution. The COBIT framework is designed to meet the I&T goals for the entire enterprise by providing a holistic approach that covers all aspects of I&T governance and management, as well as by enabling customization and tailoring to suit different contexts, needs, priorities, etc.14 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Framework:

The number of business processing hours lost due to unplanned service interruptions would be an appropriate metric associated with an enterprise goal of business service continuity and availability. A metric is a quantifiable measure that is used to track and assess the status of a specific process or activity. Business service continuity and availability is one of the 17 generic enterprise goals defined by COBIT that describes the desired outcome of ensuring that critical business services are delivered at agreed levels and are resilient to disruptions. The number of business processing hours lost due to unplanned service interruptions is a metric that reflects how well this outcome is achieved.13 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Framework: Governance and Management Objectives

Explanation
The IT implementation methods design factor describes how an enterprise develops, delivers, and maintains its IT solutions. DevOps is an IT implementation method that emphasizes collaboration, automation, integration, and feedback between the development and operations teams throughout the software development life cycle. One of the management objectives that should be prioritized when using DevOps is managed solution identification and build (BAI03), which involves defining, designing, building, testing, and deploying IT solutions that meet stakeholder requirements and expectations. This management objective supports the DevOps principles of continuous delivery, continuous integration, continuous testing, and continuous deployment, which aim to deliver high-quality IT solutions faster and more reliably.References: :
