Lesson summary

This lesson introduces the concept of systematic investigation, which is the structured, step-by-step process engineers use to solve problems. In Ghana, we are surrounded by challenges that require engineering solutions—from perennial flooding in our cities and unreliable power supply ('dumsor') to improving agricultural yields and managing waste. Engineers don't solve these problems by guessing. They use a reliable, logical method to understand the root cause of a problem before designing a solution. Understanding this process is the first step toward thinking like an engineer and developing solutions for our own communities. This lesson will break down that process into manageable steps.

Lesson notes

What is Systematic Investigation?

Systematic investigation is an orderly, logical, and step-by-step approach to finding the root cause of a problem and developing a reliable solution. It is the opposite of a trial-and-error or haphazard approach. It ensures that conclusions are based on evidence and data, not on assumptions or guesses. Think of it as a detective's method for solving a case, but applied to engineering challenges.

The process can be broken down into several key steps. While different books might use slightly different names, the core ideas are the same.
