I think you have two issues, the distinction between leadership and management and the ditinction between project and programme.I see leadership as more motivational, providing direction and vision with Management supporting that by controlling resource use within a more contrained set of circumstances.I see Programmes as collections of related projects. The formalised models also tie that to benefit realisation, noting that some projects don't realise tangible benefit but are enablers for others.If a project doesn't realise tangible benefit that I'd be looking to find out what project it's related to which will.
