To create effective service level objectives (SLOs) that gauge the reliability of a product, organizations should consider what SLOs can and cannot do for them. Setting realistic SLOs based on current capabilities is crucial to avoid engineers burning themselves out or ignoring SLOs altogether. SLOs can help determine the severity of an issue, delineate clear boundaries between components, and guide business priorities by assessing how well they are meeting SLOs. It's essential to consider different stakeholder perspectives, such as customer success managers and technical teams, to ensure effective collaboration and alignment. The definition of "working" will also change depending on the context and use case, so it's critical to clearly define what "working" means in a given context. Understanding who the users are and what level of performance they expect from the service is vital to setting effective SLOs.
