For 1), yes, there is an "observe" step in the process where - when the project is deployed - it observes and reconciles what happens vs what should happen based on specs.
I believe more variant are bound to emerge when harnesses become more prevalent. We only scratched the surface, so don't generalize over the process yet.
I'm not from McKinsey, but from BCG Gamma (speaking from my own PoV, of course).
One thing I've learned over time: expensive fees are a feature, not a bug.
People will listen more to what you have to say about any topic if they're paying a few hundred $K for that. And the same goes when you need to deliver a new tool to your client. Being expensive means my IT tickets won't be shelved for a week or two because some guy didn't like my face.
It's often the case where a 3 weeks process with a five-people-approval form gets shortened to a single zoom meeting plus an email, and I really like that :). That's the difference between a 8 weeks project being put in production two weeks early and already getting traction because the "business people" are more engaged ; and a 2 years project going nowhere because the team gets shuffled constantly and requirements keeps changing.
PS: It only works if you can deliver what you promised, though
Ads are forbidden on my network. I'm running a strong pihole that forbid advertising domains, obnoxious tracking and well known malware sites. Sponsored search results do not work and some websites are inaccessible, but it's fine, we don't need them. Ads are "The Great Evil" I will teach my children to fight, in all their forms, before drugs and alcohol.
If you are running an ad-dependant website and struggle to make money as a result of the campaign people like me are running, then you'll have to adapt. If you fail to adapt and your website closes, it's fine : as a society, we didn't need your services.
It's even worse. Apparently a critical phone call was intercepted by the DGSE (the french intelligence) before the attacks (Thursday), and transferred to the DGSI (the french counter-intelligence). The two are supposed to cooperate but the threat level could not be assessed by the first one. So, the second one scheduled a meeting on Monday (3 days after). The attacks took place between the two events.
