WHAT WAS PREDICTED TO FOLLOW
Each number on the map marks a root cause that action reduces.
① The station supervisor introduces a mandatory sign-off slip for every on-the-spot ramp request not in the system, effective the first Monday of next month, and no assistance is given until that slip is signed.
we expect: The number of ramp requests in the system will decrease by x% from its current average over the next 60 days
measured by: Number of ramp requests in the system
due 27 Nov 2026
guesses: the room: 30 (median of 11, spread 12 to 142)
② The dispatcher records every ramp request not in the system in the daily log within 15 minutes of the request and notifies the supervisor for sign‑off before the bus departs.

③ The rail company's operations management will allocate 5% of the annual transport budget to maintenance and upgrades of ramps and lifts at stations by the end of 2024.
no prediction about this action yet
④ The IT department implements a real-time notification system for all public transport vehicles by the end of Q2 2024.
no prediction about this action yet
⑤ The transit authority deploys a mobile app for drivers to approve ramp requests in real time without supervisor sign-off by Q4 2024.
no prediction about this action yet
⑥ The disability lobby group will be asked to provide a list of anticipated requests well in advance of rush hour through a monthly meeting, and the system will be updated accordingly.
