Disruptive incidents can arise in any organization; therefore, incident management is imperative to combat outages, secure services, and ensure reliability. IT incidents can range from minor events that require nothing more than a review to major service interruptions that cause loss of revenue or reputational damage. The work of managing them, which is often urgent and complex, puts strain on IT teams. This makes incident management a critical success factor for any organization.
Incident management is any process used in IT operations or DevOps for logging, recording, and resolving events that hinder business performance to restore service as quickly as possible. For example, network latency issues, container failures, unresponsive DNS servers, and outages caused by unoptimized database queries all count as incidents.
Distinct from processes for resolving bugs, defects, or problems that surface during testing, incident management applies to issues that arise when a product is live. Its core purpose is to resolve incidents quickly and efficiently.
However, the review process that follows an incident helps to identify causes and generates learnings that can mitigate future incidents. This step shares themes with problem management, which focuses on streamlining operations to address problems at their root.
An incident management process enables organizations to confront issues immediately and mitigate negative consequences, which can be significant.
The loss of customers and of business revenue can directly result from an incident and the response that follows. Poorly managed incidents keep organizations from delivering the level of service that customers expect. Customers may experience obstacles to their own productivity and bottom line or other frustrations that affect their happiness—and their loyalty.
Global cybersecurity regulations mandate that organizations use incident management to protect sensitive data. Failure to establish a formal process or to prevent a breach could incur financial penalties and cause reputational damage.
Incidents can occur 24/7. This means many professionals in this field work on-call, often in a state of urgency, and burnout can manifest easily. An effective process can harmonize monitoring systems to minimize alerts, so on-call staff won’t be notified unnecessarily, and manage other pain points to lower stress. An organization’s approach to incident management factors into its success with hiring and retaining staff in these critical roles.
Each organization takes a different approach to incident management that accounts for their unique needs, teams, and structure. No two processes look exactly alike, but two styles are commonly used: ITIL, as taught through information technology infrastructure library certifications, and DevOps and site reliability engineering (SRE).
The IT approach to incident management uses a strong incident management plan, structured with defined steps that map to roles. The ITIL incident management process is one of the most widely adopted IT frameworks. It follows these steps:
Identify an incident through testing, user feedback, infrastructure monitoring, or another measure, and log the incident for future reference.
To log an incident, record:
Categorize the incident based on its type (i.e., software, hardware, or service request). Prioritize the incident based on its impact, severity, and level of risk so that data from tracked incidents can influence better business decisions and problem management.
Investigate the details of the incident to determine how to resolve it; gather information to prevent it from happening again. After determining the root cause, identify and test a hypothesis to come up with a diagnosis.
After diagnosing the incident and determining how to resolve it, implement the resolution, test it, and bring the system back to its previous working condition.
Retest the solution. If everything is working as intended, and the user who reported the incident indicates the service is restored and marks it as resolved.
A newer, less structured, but equally effective approach to incident management stems from DevOps teams and SREs. It’s more of a culture than a framework, and several key elements define its character.
DevOps and SRE engineers value data and put metrics front and center within incident management. Through the continuous refinement of measures that monitor performance and identify issues, detection becomes proactive and forms a part of everyday operations. This approach prevents incidents from becoming serious by making sure they are detected early and met with a plan. Furthermore, with the right telemetry, predictive analysis can be used to foresee incidents and even prevent them outright. Each incident teaches the team how to better prepare for the next.
While the ITIL incident management framework maps to individual roles, teams take the spotlight with DevOps and SRE incident management. There’s never just one person responsible for resolution because pooling resources supports efficiency and valuable insights can be found across an organization. It’s about skills, not job title. Still, the people who built the system know it best and are certain to be involved in fixing it.
Including engineering teams in the incident management process holds them accountable for their work and prevents conflict between departments. This ensures that solving problems takes priority. End-to-end involvement means with each incident, engineers learn from mistakes and improve multiple capabilities. The knowledge they gain helps them to prepare for and solve future incidents, as well as to minimize incident occurrences by adjusting the way they build.
These key elements demonstrate how comprehensive the DevOps and SRE incident management approach is. While there’s no standard set of steps, the process does follow some general stages:
Through strategic monitoring of whole systems using continuously optimized tools, teams regularly expose vulnerabilities and detect incidents early as part of their regular work. Detection isn’t limited to a single role.
After an issue is detected, the incident commander takes charge of coordinating the response. This includes bringing the right people together to investigate the incident, gathering data to determine actions to take, and communicating with internal and external stakeholders.
Incidents serve as learning experiences and spark continuous improvement. As part of a post-incident review or retrospective, the data is analyzed — without blame — and applied to action plans, documentation, and runbooks for future incidents or to development work that could prevent them.
People drive effective incident management, and assigning roles to different contributors helps manage the process. These are three common roles in incident management:
Effective incident management involves storing, filtering, and managing data in a centralized way. This allows teams to address problems systematically, instead of on an ad-hoc or reactive basis, giving them more oversight and improving their ability to stop problems early.
Using the right processes and tools promotes clear communication, both to stakeholders and among collaborators, and ensures lessons learned from incidents can be applied in the future:
The right steps and the right tools make the foundation of effective incident management, but results depend on taking the right approach. Four key practices optimize the incident management process:
