These new features meant shorter waiting times at the lobby, shorter travel times in the elevator (since the max number of stops it makes before yours is 3), and access to news updates. Ultimately, it lets you get to your work desk more quickly than before.
Aside from improving efficiency, I have also observed that the new lift system has altered the social dynamics in the organisation. The 1st floor lift lobby that used to be bustling with people during morning peak hours is now much emptier. Staff used to spend time at the lift lobby catching up with one another, but now everyone is busy catching the lift assigned to them at the gantry.
When I was new to the organisation, I was advised to always have an elevator pitch ready as you never know who you may meet in the lift. However, with the strict cap of 4 destination floors per lift, the probability of meeting the big boss in the lift is significantly reduced. Even if you did beat the odds, the shorter time for travel meant that you probably cannot cover much of your pitch anyway. In view of this, most spend the time commenting on the news update on the TV screen.
It's a shame that lifts, which can bind people together (i.e. in enclosed spaces like the lift lobby or the lift itself), are typically not recognized as social enablers, unlike the more common water cooler or printer.
