Investment banks routinely win several mandates at once and must decide which available banker should lead which deal. Each banker has a different expertise, seniority and workload, so each banker–deal pairing carries a different cost in staff hours and opportunity cost. This report treats that decision as a classical assignment problem from Operations Research (OR) and solves it with the Hungarian method (Kuhn, 1955). A literature-based analysis is combined with a fully worked example of five bankers and five deals, using illustrative cost data in Rs lakh.

The Hungarian method finds a minimum total cost of Rs 82 lakh. Staffing the deals in simple sequential order costs Rs 103 lakh, and a greedy rule costs Rs 97 lakh, so the optimal assignment saves 20.4% and 15.5% respectively. The result is certified optimal in two independent ways: a dual (lower-bound) check and complete enumeration of all 120 possible assignments. The report closes with a critical analysis of the model's strengths and limitations, and with extensions needed for real-world use.
