Effektiv vs. effizient
The German words effektiv and effizient both deal with achieving results, but they differ in focus. While effektiv relates to achieving the desired results regardless of the means, effizient highlights achieving those results with the least amount of resources, time, or effort.

Summary
The difference between effektiv and effizient lies in focus. Effektiv emphasizes simply achieving the goal, regardless of how much effort or resources are used, while effizient prioritizes achieving the goal while using resources, time, or effort as optimally as possible. For effective solutions, consider their ability to solve a problem; for efficient ones, evaluate whether the solution minimizes effort or costs.
