Software development is a complicated process as it involves five different stages: designing, coding, testing, and maintenance. Among these, testing is the most challenging phase, which is performed by QAs. One of the most difficult tasks for QAs while testing a web app is tracking and eliminating bugs.

When organizations implement SLOs, they can improve software development processes and application performance. SLOs can be a great way for DevOps and infrastructure teams to use data and performance expectations to make decisions, such as whether to release and where engineers should focus their time. SLOs improve software quality.
