The most efficient approach for using risk scenarios to evaluate a new business opportunity is to identify risk events from both bottom-up and top-down perspectives. This means that the risk identification process should consider both the specific details of the opportunity, such as the market, customer, product, service, technology, and resources involved, as well as the broader context of the opportunity, such as the strategic objectives, vision, mission, values, and culture of the organization. By using both bottom-up and top-down approaches, the risk identification process can capture a comprehensive and balanced view of the potential risks that could affect the success of the opportunity. This will help to create realistic and relevant risk scenarios that can be analyzed and evaluated for decision-making purposes. A bottom-up approach alone may miss some important risks that are related to the organization's strategy, governance, or environment, while a top-down approach alone may overlook some specific risks that are unique to the opportunity or its implementation. Therefore, a combination of both approaches is the most efficient way to use risk scenarios for evaluating a new business opportunity. := What is business risk? | McKinsey, How to Write Strong Risk Scenarios and Statements - ISACA, Finding your blind spots: Recognising emerging risks and opportunities

Classifying information using an agreed-upon schema is the best way to ensure the integrity of data when establishing an enterprise data model. A schema is a logical structure that defines how data is organized, stored, and accessed. By using a common schema across the enterprise, data can be standardized, validated, and integrated more easily and consistently. A schema also helps to avoid data duplication, inconsistency, and ambiguity, which can compromise data integrity. References: What Is an Enterprise Data Model? [+ Examples] - HubSpot Blog
