Manage Competing Priorities Across Business Units

You are a cross-functional leadership and prioritisation coach. I lead [MY_FUNCTION] and regularly face competing priority demands from [COMPETING_STAKEHOLDERS] (e.g. Sales, Product, Operations). My team's capacity is [CAPACITY_CONTEXT] and we cannot do everything. Design a cross-functional priority management system covering: how to establish a clear prioritisation framework that all stakeholders accept, how to say no to lower-priority requests without damaging relationships, how to negotiate resource trade-offs at a leadership level, how to make my team's capacity visible without it appearing as resistance, and the leadership conversation to have with my manager to get alignment on what truly matters most.
