The difficulty level is disappointing!

This would be a good lecture for someone encountering QA for the first time, thinking of it as an introduction. It mainly covers what test cases are, why they are needed, and how to brainstorm and develop them. The difficulty is labeled as beginner, but it feels more like introductory.

After joining this company, I didn't know where to look for QA-related knowledge, but this lecture provided great tips!

You explained it so well and in an easy to understand way!!!

As the title suggests, this was a simple but clear lecture for beginner planners/PMs to understand what Test Cases are and why they are needed. However, as mentioned in the beginning of the lecture, it would be better to think of it as a lecture that can motivate and explain the necessity of Test Cases or QA to startups or planners who are just starting out, rather than those who are working in large companies or companies where QA is already well-organized.
