   Operations research

   — Without selling more or spending more, where does profit come from?

   Operations research answers the question rigorously: budget allocation across heterogeneous campaigns, dynamic pricing under demand uncertainty, inventory policy under stochastic lead time, voucher-tier discipline against category-margin constraints. The math that says "cut here, reallocate there, wait for that" — proven before it deploys, with Bayesian and causal methods used inline as the underlying inference machinery.

   Risk-aware optimisation

   — The finance + uncertainty modelling that keeps the optimum honest.

   Robust optimisation puts a hard floor under every decision. Worst-case scenarios are modelled and capped before any action ships — CVaR-95 below the margin floor is not deployed, regardless of how high the expected value sits. Margin reconstruction down to the order line, returns-reserve provisioning, working-capital modelling under campaign-driven demand spikes, and probabilistic price-elasticity estimation per SKU make the cost stack precise enough that the risk math has something real to bound.
