How does the Business Manager manage project profitability?

P&L (Profit & Loss) management is at the core of the role. In practice: the BM builds the project budget (estimating internal + external costs + subcontractors), tracks financial progress (costs incurred vs. budget), anticipates variances (schedule slippage, cost overruns), and manages scope changes (contract amendments). They are often the only person capable of simultaneously managing the commercial (client satisfaction), technical (quality, timelines), and financial (margin) threads. This triple hat is what makes them valuable.
