Dear Sir,
We are organising a technical case study event called xyz during our technical fest xyz to be held from xyz to xyz. The case study will be organised under the supervision of a company. We are looking forward for your assistance for the same.

xyz will consist of 2 rounds. In the preliminary round, participants will be given an actual technical situation involving a decision to be made or a problem to be solved. The problem statement will be provided by the company itself. Based on their solution to the problem some participants will be shortlisted for final round. In final round participants will discuss and explain their solution to the representative of the company who visits our college. The final winners will be decided by the company representative.

Our college has immensely talented and potent minds who will provide innovative and reaistic solution to the problem. It will be certainly a great pleasure and honour to have you as superviser.
