In professional services, which includes finance, property and business affairs as well as marketing, communications and audiences, costs will be reduced by 25% (£57m). Divisional support will also be reduced.
Total number of posts affected will be 2,500, with half the cuts coming as redundancies and half outsourced, leading to savings of £68m.
Better procurement and non-headcount savings will total £93m, and there will be 15% efficiency savings in output areas such as radio and music, TV, new media, BBC news nations and regions, generating £79m in savings.
There will be another 15% savings in cost-per-hour prices for commissions from all supply sources, totalling £80m. This excludes sports rights.
Thompson said: "Plans will combine programme strategy aspirations, value-for-money savings and the impact of other reviews. This means net redundancies may be less than a 15% savings target suggests.
"We want to invest in new content while also making productivity gains in existing output. It may mean fewer posts on existing tasks, but new posts for new tasks. But we need to save before we can spend."
