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.

Problematization is a term that can also be translated as problem-raising or problem-framing. It can also be translated as problem-setting or problem-definition. It is a concept that encompasses the process of questioning known facts such as requests or common sense from new perspectives, defining problems, and working out ways to solve these problems. While problematization should be the starting point of all development, it remains an insufficiently discussed topic in the development field. Carrying out projects or developing programs is, in fact, about creating plans to solve problems. In other words, it is related to problematization. To solve a problem, the problem must first be clearly defined. However, problems are usually given in the form of vague requests. Therefore, having the ability to transform vague requests into clear problems reduces unnecessary 'development waste,' facilitates smooth collaboration, and enables proper understanding of users' real needs. This course helps train 'problem-constructing thinking' through practical cases and tools.
