I saw a presentation by Phil Davies (producer of ‘Peppa Pig’) a while back, and one of the things that stuck with me was this:
In the early days of their studio, when they developed many concepts, they would put them to this test: After writing a brief synopsis of the show idea, how easily would the first 52 episode ideas flow?
They found that the ‘Peppa’ ideas almost wrote themselves – which was a good indicator of a strong and well defined concept.
The same approach can be used as a litmus test in many other fields as well: How easily can you come up with the chapter ideas for your book? Is it easy to outline your software project plan? What about the next steps on your carreer path?
If you run into problems there, you might need to clarify your basic concept and goal.
