Background: I have done a scientific project as a part of my graduation program and now I want to present my work through presentation slides. There were some techniques which didn't work and meant I had to employ other techniques. I want to name those techniques on a single slide, but I am unable to find a suitable title for that slide. I don't think that I should use "Challenges" as the title, because I think that that would only be suitable for techniques which posed some problem to me but I managed to solve them somehow.
What should be the title of the slide on which I present the techniques that failed?
Best Answer
"Approaches Tried" (particularly if you're giving an account of things you tried that didn't work on the path to discovering the technique(s) that did work)
"Other Approaches Tried"
"Unsuccessful Approaches"
"Unsuccessful Techniques"
