You know, there is a bit of politics, but I've come to the conclusion that it's better to just hose down the managers with "techy-stuff" rather than try to sell them power points with bullshit. After all, if they are making the decision, they should actually either get it, or trust you to get it for them.
The one thing that does not fly is developers that does not know the business case, or worse, those that don't care and acts like the company's purpose is to give them new toys (frameworks) to play with. But grokking a business case is marginally harder than resolving a merge-conflict so most people are actually presentable in a steering committee meeting.
Anyway; 200.000 € is probably not a developer, but possibly someone with a development background.
Unfortunately only a few people can sell things to the (non-tech) management - that is typically harder for us square-headed developers, as you have to be able to skimp some details in order to convey the big idea. But selling ideas is a unique skill anyway.
