Where the points actually are

Judges at this level see hundreds of plausible ideas. What separates the advancing teams is evidence: having actually spoken to people with the problem, and being able to say what you learned that changed your plan. A modest idea with twenty customer interviews behind it beats an ambitious one built entirely from assumptions.

Topic breakdown

01Problem definition: Name a specific problem experienced by a specific group of people. Judges discount broad problems stated in the abstract almost immediately.
02Customer discovery: Talk to people who have the problem, before you design the solution. Record what surprised you. This is the section most entries are thinnest on.
03Business model: How money moves: who pays, how much, how often, and what it costs you to deliver. For the social track, how impact is sustained rather than how profit is made.
04Evidence of traction: Anything real: a prototype, a waiting list, a pilot, a signed letter of interest. Small real evidence beats large projections.
05The pitch: Written first, then live. In both, the first thirty seconds should make the judge understand the problem without any jargon.

A study plan that works backwards from the date

September Register, then spend the first month only on the problem. Interview at least fifteen people who actually have it. Write down what you got wrong.
October Design the solution against what you heard. Build the cheapest possible prototype, even if it is paper.
November Work out the business model and the numbers. Attend the free Diamond Challenge support events; they are pitched at exactly this stage.
December Write the submission. Have an adult outside your team read it and tell you what they did not understand.
Early January Revise and submit well before the deadline. Then start practising the live pitch, because semifinalists have less time than they expect.

Tips that come from the format itself

Pick the right track. Social Innovation is judged on impact sustainability, not profit, and entries in the wrong track are effectively penalised.
Customer interviews are the highest-leverage hours you will spend. Fifteen real conversations changes the entry completely.
Free pre-submission support events run every year and most teams ignore them.
Teammates can come from different schools and countries, which lets you build a team around complementary skills rather than proximity.
Past winning pitches are published. Watch three before you write anything.
