This guide explains software maintenance in plain language for business owners and managers: what it really involves, how to decide what you need, the terms you will hear and what a good outcome looks like.
What software maintenance really involves
Software maintenance is preventive care: security patches, dependency updates, backups, monitoring and small fixes that keep a system healthy.
How to decide what you need
Budget for maintenance from the start, typically a monthly plan, rather than paying for emergencies when something finally breaks.
Key terms you will hear
| Term | What it means |
|---|---|
| SLA | Service level agreement defining response and resolution times. |
| Uptime | The share of time a system is available. |
| Patch | An update that fixes a bug or security issue. |
| Technical debt | Shortcuts in code that make future changes harder. |
Typical project sizes
| Level | Typical scope |
|---|---|
| Website care | Updates, backups, monitoring for a website, per month |
| Application support | Patching, fixes and enhancement hours, per month |
| Critical systems | Fast response, monitoring and dedicated capacity, per month |
What success looks like
Success is a system that stays fast and secure, with incidents caught by monitoring before users report them.
