Understanding SLAs: A Guide for Small Business IT Teams

What Is an SLA?

A Service Level Agreement (SLA) is a commitment between the IT team and the business about how quickly issues will be resolved. It answers three questions: how fast will we respond, how fast will we fix it, and what happens if we don't.

Why Small Teams Need SLAs

Without SLAs, every ticket is equally urgent — which means nothing is urgent. A broken printer gets the same attention as a server outage. SLAs create a shared understanding of priorities and give the IT team a framework for saying "this is critical, drop everything" vs "this can wait until tomorrow."

Setting Your First SLA

Start simple with three priority levels:

Priority	Definition	Response Target	Resolution Target
Critical (P1)	System down, multiple users affected	1 hour	4 hours
High (P2)	Major feature broken, single user critical	2 hours	8 hours
Normal (P3)	Routine issues, requests	4 hours	24 hours

Adjust these based on your team's actual capacity. It is better to set achievable targets and consistently meet them than to set aggressive targets and constantly miss them.

Measuring Compliance

Track these metrics monthly: percentage of tickets resolved within SLA, average response time per priority, average resolution time per priority, and number of SLA breaches. Share this data with management in a one-page monthly report.

Aim for 95% compliance as your baseline. If you are consistently below 90%, either your SLA targets are too aggressive or your team needs more resources.
