Most office workers work hard on their reports. The data is sufficient, and the logic is sound. Yet, the results are always the same: - “Let’s review this.” - “Let’s supplement this a bit more.” - “Let’s discuss this again at the next meeting.” The problem isn't that you can't write. It's because the document is not designed to trigger a decision. This lecture is not just about how to write a report; it covers how to design a document according to the structure of how decision-making actually happens. Over 26 years of reviewing countless reports in major corporations and investment fields, I found one commonality from the perspective of someone who actually "makes the decisions": [Decisions come from the structure of the report, not just the content!] In this lecture, we will: Analyze where executives stop their judgment Identify what must be present for a decision to begin through real-life cases, and provide methods to transform your documents into a structure that is written quickly and approved immediately.

Many practitioners and aspiring executives have learned about strategy, but they often feel lost when it comes to deciding what to analyze first and how to execute it. While they may understand market analysis, business strategy, KPIs, and partnership strategies individually, the biggest problem is that these elements are not connected into a single flow, failing to lead to actual decision-making and results. This course is designed to solve these concerns. It provides a step-by-step guide to the thinking structure and analysis sequence of B2B business strategy used in actual corporate fields, along with methods to transform them into actionable outcomes. Rather than textbook theories, the focus is on strategic frames and decision-making criteria that can be applied immediately in a corporate setting. Dr. Jake, who has spent 25 years in strategic planning and business development at global IT companies as well as major and mid-sized Korean corporations, will bridge the gap between theory and practice. He will clearly define "why this strategy is necessary, when to use it, and how to execute it." Through this course, students will: 1. Go beyond merely explaining strategy in words. 2. Gain the power to analyze markets, design strategies, and connect them to execution and KPIs on their own.

A report is not a document to be read. It is a structure that produces decisions. Diagnose why things stop, analyze where they get stuck, and design it so that a decision becomes unavoidable.
