Unplanned maintenance is often planned downtime waiting to happen. Systems need regular attention: updates, checks, backup tests. If that attention is not organised, it turns into an emergency intervention sooner or later.
Why plan rather than react
Reactive maintenance costs more than planned maintenance. Not just in intervention time, but in impact: an outage during a client meeting or a busy period causes damage that a technical fix does not fully repair.
Planning also means deciding in advance what is a priority, before an emergency decides for you.
Identify the tasks and how often they need doing
Start by listing what needs to happen regularly on your infrastructure: operating system and application updates, backup health checks, error log reviews, audits of active accounts.
For each task, answer two questions: how often does it need doing, and what is the impact of skipping it? That is what separates tasks that can wait from tasks that cannot.
Prioritise the tasks
Not all maintenance carries the same weight. Some tasks are critical: skip them and a major outage becomes likely. Others are important but not urgent. Others are useful but can come after.
This classification is what makes a realistic schedule possible. If everything is marked ‘urgent’, nothing really is.
Build a schedule that accounts for the business
A maintenance schedule is not just a technical document. It needs to account for the life of the business: avoiding high-activity periods, coordinating with the relevant teams, allowing testing time before a significant update goes live.
Maintenance that surprises users at the wrong moment, even when it runs perfectly, is experienced as an outage. Communication is part of planning.
Test and validate, not just tick boxes
A completed task on a schedule is not necessarily a well-done task. Backups need testing: knowing a backup exists and knowing you can restore from it are two very different things. Updates need to be verified after deployment.
The point of good maintenance tracking is to distinguish ‘done’ from ‘working’. On this, the best practices for preventive maintenance are a useful complement to planning.
Keep a record of what was done
Documenting interventions has immediate practical value: it lets you understand the history of a system when something changes or breaks. A simple log (date, action, result, any anomaly) is enough to build an institutional memory of the infrastructure.
Without it, every problem gets solved from scratch, even when the answer already exists.
