an sccm would be taking 17 crew under his / her wing ,performance managing them
The best thing about being in this industry for a quarter of a century is that you get to see old ideas, which didn't work and were scrapped, being reinvented and launched to a great fanfare. So here we go again!
Last time (circa mid 90's) it was called FIP (Fleet Improvement Plan) every CSD had a PSR and a group of main crew and was supposed to fly with them at least twice a year. This proved unworkable due to scheduling constraints so it became once a year which still was too hard so it died a sudden death with everyone agreeing that it was a great idea but just couldn't be made to work given the logistical problems. We also had Fleet Directors (early 90's), who had a small team but only really managed to fly with their CSD's so that didn't manage the main crew or pursers. Most recently 'CSD X' has been kicked around as well.
The bottom line with crew is that they have to be managed on the day by the SCCM so you have to be sure you've promoted the right people.
it would be performed on a per flight basis based upon customer surveys
It is nigh impossible to performance manage based on customer feedback given that the feedback is flawed and affected by general perception of the whole journey experience. (Many customers will complete their form before even seeing their meal much less eating it!) Even CSD annual reviews can only use trends from GPM's and these are greatly influenced by the fact that for the most part, a customer will only oblige with a GPM if they're in a good mood to start with.
So call me cynical but I look forward to the re-invention of the wheel with great anticipation but very little hope that it will herald any great transformation.
