The issue impacts essential services or renders the service inaccessible, degrading the customer experience.Ī severe problem affecting a limited number of users in a production environment, degrading the customer experience.Ī not-so- major incident that causes errors, excessive load, or minor problems for customers in a production environment.Ī relatively minor problem that affects customer experience without substantially degrading service functionality.Ī low-level problem that causes minor errors-such as formatting or display problems-that doesn’t degrade usability.Ī three-level system could look like this: PriorityĪ significant incident that has a broad impact. A five-level system typically looks something like this: SeverityĪ critical problem affecting a significant number of users in a production environment. These usually follow a pattern like the ones below. Typically, organizations adopt three or five severity levels. If not, the severity levels need further refinement. If their severity levels align, you have successfully established the common language. You can run some hypothetical incident response scenarios by team members as a stress test. Most importantly, ensure everyone understands the wording. The advantage of such a system is that it arises from a collective effort and implies a decision tree to classify incidents. Your team may find it easier to identify various severity levels through a spider diagram or mind map by looking at the resulting clusters. Even if you may not benefit from using another company’s exact system, their levels can still form the basis for yours.īrainstorming helps too. You should pick a similar source-for example, a company in the same industry. One strategy is to reference the severity levels from another team or company. ![]() The right language for your incident response team depends on factors such as your organization’s size, the nature and frequency of incidents, and your team’s composition. What works best for one organization may not be ideal for another. Ultimately, you can employ various strategies to come up with a common language. For instance, severe incidents may demand an all-hands-on-deck response that requires contacting team members on a holiday. Whatever you pick, you should ensure your team understands the chosen language and the reasoning behind it, allowing them to comprehend each incident on a higher level.Ĭlassifying your incident’s severity level helps ensure a consistent response and prevents confusion about how to proceed. Your team needs to find and apply a common language to communicate efficiently. Then, we’ll discuss how your organization can put a strategy in place that works best so your team feels empowered to react quickly and appropriately when incidents strike. Let’s explore how to define your incident severity levels and examine some popular systems for doing so. Setting this severity level system in place ahead of time helps teams quickly understand the amount of urgency required in a situation while enabling effective prioritization. One way to facilitate an efficient response is by using a transparent system of incident severity levels that teams can reference easily: helping to minimize incident response time while strengthening efforts to coordinate remediation throughout the response team. The impacts and severity of a system outage affecting 10% of your users are different from an outage impacting 90%. ![]() On top of that, not all incidents are created equal. Several factors can impact system performance, cause outages, or impact customer experience. Maintaining IT infrastructure is a consistent challenge for system administrators, site reliability engineers (SREs), supporting developers, and technicians.
