Major incident management is a key aspect of IT operations and cyber security. When an unexpected event disrupts normal business operations, it requires a coordinated effort to resolve the issue and minimize its impact. With the increasing complexity of IT environments, managing major incidents has become more challenging. This article explores the challenges of major incident management and the benefits of automated incident response for incident teams. Additionally, it provides an overview of what automated incident response is.
What is a major incident?
A major incident is characterized by:
Significant impact: Affecting a large user base, important business processes, or revenue streams.
Examples:
- A complete payment processing failure on a major retail website during the “Black Friday” sales period that affects every customer trying to buy something (large user base), directly halts the core business process (sales), and results in an immediate, massive loss of revenue.
- A system outage at a financial services company that renders all ATMs and mobile banking apps unusable for several hours. This affects millions of users globally and locks customers out of accessing critical financial services.
Urgency: Requiring immediate attention and resolution.
Examples:
- A data center power failure affecting a major cloud service provider, causing dozens of client services to go offline simultaneously. The services being down directly impacts client businesses and every minute of downtime translates into massive contractual penalties and reputational damage, making immediate response essential.
- A malware infection that locks down a hospital’s electronic health record system. This is life-threatening; patient care is directly compromised, necessitating an "all hands on deck" response to restore access to patient data immediately.
Complexity: Involving multiple teams, systems, and dependencies.
Examples:
- A networking change at a telecoms company that inadvertently causes a cascading failure across three different microservices: authentication, billing, and the primary content delivery network. The incident isn't confined to one application; it requires network engineers, application developers, and database administrators to collaborate, each confirming their component's health and troubleshooting where the failure 'jumped' from one system to the next.
- A production database cluster suffers a primary node failure. The automated failover mechanism successfully promotes a replica but due to a subtle configuration drift in the network load ballancer, write operations are intermittently routed to both the new primary and a stale former primary node. The failure is a symptom of interaction between independently functioning components, making the root cause difficult to isolate without unified, multi-disciplinary effort.
High pressure: Demanding clear communication and decisive action under stress.
Examples:
- A widespread service outage where the company’s CEO and Board of Executives are demanding hourly status updates and the media is already covering the story. Beyond the technical fix, the team must manage intense internal and external scrutiny. The pressure comes from the need to make perfect technical decisions quickly while also maintaining clear, frequent, and calm communication with executive leadership and public relations teams.
- A bug in a financial trading system that causes incorrect execution of high-volume stock trades just as a major market event is happening. The immediate financial risk is enormous, compounded by regulatory compliance concerns. This necessitates extremely swift, confident, and legally sound decision-making under the stress of potentially huge monetary losses.
What are the top major incident management challenges?
Major incident management involves several challenges, including:
1. Time sensitivity
Major incidents often have significant business impacts, such as downtime, financial loss, and damage to reputation. Rapid resolution is important to minimize these impacts. However, major incident management presents several challenges, including the time required to mobilize teams or diagnose and remediate incidents, which can be prolonged due to the complexity of the environment and the need for coordination among various teams.
2. Inefficient coordination and communication
Effective incident management requires seamless coordination and communication among multiple teams, including IT, security, and business stakeholders. Miscommunication or lack of coordination can lead to delays in incident resolution and exacerbate the impact. One major incident management challenge is ensuring that all relevant teams - such as engineering, operations, security, and support - can collaborate effectively and don’t operate in silos. Fragmented communication and delayed information sharing can hinder incident response efforts and the lack of a centralized communication platform can result in missed updates, duplicated efforts, and conflicting information, further complicating resolution and prolonging downtime.
3. Lack of real-time visibility
Major incident managers often lack a comprehensive, real-time view of the incident's status, impacting their ability to make informed decisions. The manual tracking of tasks and progress can be error-prone and time-consuming, hindering efficient resolution. At the same time, stakeholders can struggle to understand status without interrupting the people doing the work at a crucial time.
