I'm currently polishing a grant proposal for the ERC Starting Grant scheme. As is typical doubts beset me. There aren't many samples available, and every one I was able to find exists in a niche of its own.
What seems to be a typical pattern is to describe at a very high level the proposed approach: for instance, we will study issue A using method B but they don't go too much in detail. For example, how is this study exactly going to happen?
Where possible I have tried to explain in as much detail my line of inquiry and the expected outcomes. However, especially for a grant with a horizon of 5 years, it's difficult to explain how the last WPs will be studied, as they might depend on the outcomes of the prior ones.
It is highly likely that these proposals I have seen were the unsuccessful ones. If you have any experience of successful ones, how much detail did you give (or make up)?
