Finally I got a grudging acceptance. The parting shot from the most senior executive was "well you'll need to get go ahead from my team" to which I was able to reply with confidence - "As key stakeholders I spoke to them this morning, walked them through my draft strategy and they were behind it." Nothing left to be said. Result!
And subsequently tomorrow starts with a 7.30am meeting, another at 8.30....... but I'm happy that I managed to drive through such a positive outcome for the organisation, and at the end of the day, one for me too on a personal level.
Got home this evening to find that my laptop has been turned into a pile of scrap by the latest Microsoft update. Have wasted an entire evening unsuccessfully trying to solve the problem. Luckily though, bit by bit, each time it restarted I managed to save my data onto the E: drive before it froze again. Grrrr! Time to rebuild anyway but just don't need it.
