This document is vital in the initial 'crawl' phase, outlining what you are trying to achieve, why, and how. It should be concise, allowing anyone to read it in less than ten minutes.

This should guide engineers by making SLO implementation accessible and generate interest without overwhelming them with volumes of information.</span><br /> +<br /> +<span>FAQ Document:</span><br /> +<br /> +<span>Compile a FAQ document to address anticipated questions as teams begin their SLO journey. Example questions include:</span><br /> +<br /> +<ul> +<li>What if my user is another service? Do I still need to care about SLOs?</li> +<li>What if my service's dependencies don't have SLOs?</li> +<li>How many SLOs should a service have?

Be specific and include examples from your organization's monitoring platforms. Address scenarios like collecting latency data, using percentiles, and instrumenting different types of services.
