Not causing any disturbance or interruption.
The changes in the schedule were nondisruptive, allowing everyone to continue their work without issues.
Nondisruptive → It is formed from "non-" (meaning not) and "disrupt" (from Latin "disrumpere", meaning to break apart) and "-ive" (meaning having the nature of). The word "nondisruptive" means having the nature of not breaking apart or causing disruption.
Think of 'not' ('non-') causing a 'break' ('disrupt') — that's why nondisruptive means not causing any disruption.
