Fail fast

Today I had a meeting with my bachelor thesis supervisor. I proposed her an idea to make my bachelor thesis about failing fast. The idea of failing fast is to launch product or business quickly to see if it fails or successes. You cannot know which idea will success therefore the best option is to try and see what happens. The supervisor said it is a great idea but her co-worker said just that the idea is ok. I am thinking about to write the thesis in English because the source material is probably going to be in English.
