A system planned maintenance schedule is a set of regular maintenance activities that are scheduled throughout the year to keep the system running smoothly. It is important to abide by this schedule because it ensures that the system is always functioning at its best, which helps prevent downtime and system failures.

If maintenance is not run as scheduled, it can cause several issues that can negatively affect your daily work. For example, it could lead to unexpected system downtime, which means you won't be able to access the system and all of its features. This can lead to lost productivity and revenue for your business.

Additionally, skipping maintenance can cause the system to become slow and inefficient, which can cause delays in processing data and performing tasks. This can cause frustration and lost time for users.

To avoid these issues, it is important to stick to the planned maintenance schedule. This will ensure that the system is always functioning at its best and that you can rely on it to support your daily work.
