Mastering Problem-Solving with Logic Trees

0

Would you like to know the secret to leading a successful project? The key lies in fundamentally solving the problems. One of the most powerful tools for solving problems is the ‘logic tree.’ In this article, we will delve into the concept and application of logic trees.

What is a Logic Tree?

Logic Tree is a compound word of logic and tree. Like branches and leaves extending from the trunk of a tree, it is a method of thinking that branches out in various directions to find the root cause of a problem. By using this method, you can clearly identify complex problems and logically find their fundamental causes.

Why Use Logic Trees?

When planning, you often face confusion in direction. Usually, when people encounter a problem, they rely on intuition to solve it. However, problems solved this way are likely to recur. Logic trees prevent such issues and provide a method to address the fundamental cause.

Main Applications of Logic Trees

Using logic trees, you can systematically solve various problems. Here are the main applications.

1. Gaining a Macro Perspective

Logic trees help you understand the overall structure of a problem. You can see the big picture at a glance, ensuring no details are missed when solving the problem. For example, in solving the problem of ‘increasing customer churn rate,’ you can analyze various causes and find the fundamental cause.

2. Flawless Logical Thinking

Logic trees are highly useful for solving problems logically. Especially when applying the ‘MECE (Mutually Exclusive, Collectively Exhaustive)’ principle, you can analyze every part of the problem without omission. This aids in logical thinking and helps in devising systematic solutions.

3. Three Types of Logic Trees: Why, What, How

There are three main types of logic trees. Each serves a different purpose but fundamentally helps in finding the core of the problem.

  • Why Tree: This involves asking ‘Why?’ repeatedly to identify the root cause of a problem. For example, to solve the problem of ‘increasing customer churn rate,’ you keep asking ‘Why are customers leaving?’ until you find the cause.
  • What Tree: This specifies the tasks needed to solve the problem by asking ‘What needs to be done?’ For instance, to secure ‘market share,’ you list the necessary tasks and create specific action plans.
  • How Tree: This focuses on ‘How to solve the problem?’ and finds solutions. For example, to ‘improve operating profit,’ you define the tasks needed and set priorities.

How Planners Use Logic Trees: Achieving OKRs

OKR (Objectives and Key Results) is a very useful tool for planners to set and achieve goals. By using a logic tree, you can create specific plans to achieve OKRs. For example, to achieve the goal of ‘reaching 10,000 DAUs,’ you can list the necessary tasks and set priorities.

Conclusion

The most important thing in planning is defining the problem clearly. If the problem is not clearly defined, the solution cannot be effective. Logic trees help approach problems logically and find fundamental solutions.

Utilize logic trees actively. By approaching problems with logical thinking, you can achieve more effective and efficient results. Wishing you successful planning!
