Why Incident Response Matters for Tech Teams
Today, businesses require adaptable, robust IT systems that can swiftly respond to changing market demands and evolving customer needs. This constant evolution results in frequent updates and releases, each carrying potential risks that could lead to disruptions or outages (downtimes).
However, the swift pace of change and inevitable growth in IT departments add complexity to system architectures and incident management. Therefore, acknowledging incidents as an expected part of the digital world, rather than anomalies, is key. Embracing an effective incident response strategy entails proactive preparation for these inevitable events.
Reframing incidents as opportunities for learning and improvement, instead of crises, promotes a proactive rather than reactive approach. This empowers IT professionals to manage and mitigate incidents effectively, minimizing their business impact. In the following sections, we'll discuss how your organization can better prepare for, respond to, and learn from incidents. Our goal is to equip your team to turn inevitable challenges into opportunities for growth and improvement.
To ensure the principles and practices outlined in this guide are applicable and effective, we need to establish a key assumption: your business operates 24/7 always-on services that, when disrupted, require immediate human intervention.
This implies that any form of downtime or service disruption is significant and carries a tangible cost for your organization - every minute truly counts.
This situation is increasingly common in our interconnected, digital world where businesses operate across time zones and customer expectations for service availability are high.
Whether you're managing an e-commerce platform, a banking app, or a global logistics system, the expectation is the same:
the service should be available and responsive at all times.
If this reflects your operational reality, then the strategies and methodologies laid out in this guide will help you mitigate the risks, manage the unexpected, and continue to deliver exceptional service to your customers, no matter what incidents may arise.
What is an Incident?
In the vast landscape of IT, terminology can often get convoluted, leaving room for misinterpretation. One such term that's crucial to understand is "incident". Although definitions can vary, they generally suggest a "deviation from the normal procedure".
To ensure clarity and foster swift, precise action, we propose a more specific definition:
An incident refers to a situation with a visible business impact, meaning it affects the user experience for your customers, whether internal or external. This can be a disruption, an outage, or any situation that affects the provided services in a way that consumers of the service notice or experience degraded performance.
This definition highlights the real-world impact an incident has on your operations and, ultimately, on your customers' experience.
The focus on visible business impact highlights the urgency and importance of incidents. The aim is not merely to get your systems back to normal but to minimize any negative effects on your business and your customers. It is this perspective that drives our incident response approach, ensuring that we not only respond effectively to incidents but also prioritize maintaining excellent customer experience, regardless of the circumstances.
This brings us to the distinction between an incident and an alert.
Incidents vs. Alerts
While both incidents and alerts play pivotal roles in managing an IT ecosystem, it's essential to understand their differences.
An alert primarily targets on-call responders, notifying them of potential incidents reported by monitoring systems, ticketing tools, or other observability tools. Alerts are technical by nature, often containing details not relevant to non-technical users.
On the other hand, an incident is the primary communication tool for non-technical users. Incidents translate the technicalities of an alert into digestible information for those affected by service disruptions, focusing on business impact and user experience.
Our definition of an incident emphasizes the real-world consequences on business operations and customer experience.
Required Tooling for Effective Incident Response
Effective incident response requires a combination of tools that facilitate swift detection, communication, response, and post-incident analysis. Here's a rundown of the key types of tools needed in an incident management toolkit:
Monitoring and Observability
Alerting and On-call Management
Manual Incident Trigger Mechanism
Communication and Collaboration
Ticketing and ITSM Tools
Incident Response Platform
Monitoring and Observability
The foundation of proactive incident response lies in detecting anomalies or issues as soon as they occur. Tools that monitor system performance, log data, and track application behavior can provide real-time visibility into your IT systems, enabling swift identification of potential incidents.
Alerting and On-call Management
Once an incident is identified, immediate notification is critical. Alerting tools ensure that the right information reaches the right people at the right time, enabling swift action. Alerting tools can also help you to automate routine tasks and processes, which can significantly reduce the burden on your response team and reduce the time-to-resolution. Automation can handle tasks like ticket creation, status updates, and repetitive diagnostic procedures.
Manual Incident Trigger Mechanism
Have a way for humans to manually trigger the incident response process when they notice something is amiss. This can drastically improve your response times. Ideally, this should be a familiar, low-friction tool. For example, you could provide a dedicated phone number for reporting incidents, which directly connects the caller with the on-call responder. Alternatively, you could enable users to report incidents directly from their daily chat tool.
Communication and Collaboration
During an incident, effective communication is paramount. Tools that facilitate rapid and clear communication among the incident response team, as well as between the team and stakeholders or affected users, are essential. This includes status pages for user communication, chat tools for real-time collaboration among responders, and video conferencing tools for incident huddles.
Ticketing and ITSM Tools
These tools facilitate the process of tracking individual incidents or problems within a system. They provide a structured interface where incidents can be reported, categorized, assigned, and prioritized. They allow teams to organize their workload and ensure that no issue slips through the cracks.
Incident Response Platform
An incident response platform ties your incident response process together. It offers functionality for coordinating response efforts, maintaining incident timelines, orchestrating communication, and conducting post-incident reviews. They streamline the incident response process by providing a centralized hub that integrates monitoring, alerting, and communication tools. This allows you to manage incidents from detection through resolution in a single platform, ensuring a coordinated response and minimizing downtime.
Each tool plays a distinct role in ensuring a fast, coordinated, and effective response to incidents, ultimately minimizing their impact on business operations and customer experience. By choosing tools that integrate well with each other, you can create a cohesive incident response system that enhances your team's efficiency and effectiveness.
Incident Response Lifecycle Overview
Effective incident response is a fundamental aspect of modern business operations, particularly in the digital landscape. Our focus in this chapter is to provide a comprehensive guide to the incident response process, encompassing every stage from preparation to post-incident learning.
The chapter is structured around four key stages of the incident response lifecycle, each representing a vital step in ensuring optimal system uptime and user experience. They are as follows:
Prepare
Set the stage for swift and efficient response by establishing the right systems and protocols.
Respond
Learn to act promptly and decisively when an incident occurs, leveraging key communication and collaboration tools.
Communicate
Discover the importance of clear and timely communication during incidents to reduce user anxiety and enhance trust.
Learn and Improve
Explore the importance of post-incident reviews to drive continuous improvement in your incident response strategy.
Throughout this guide, we aim to provide a detailed roadmap for managing incidents effectively, keeping user impact minimal, and fostering a culture of continuous learning and improvement in your organization.
We will use ilert’s incident response platform as an example to demonstrate the recommended steps. However, the essence of these procedures could be replicated with other tools, depending on their features and capabilities. While having a tool is crucial, the strategies and procedures outlined can be applied universally. Let's dive in.
Systems and Protocols for Swift Response
Preparation is the cornerstone of effective incident response. The more you're prepared, the better your response will be when incidents occur. It involves setting up systems and structures that facilitate efficient detection, notification, and resolution of incidents. Here's what you need to do:
Set Up Monitoring and Observability
The first step to effective incident management is setting up tools to monitor your systems and applications. These tools provide real-time visibility into your IT environment, allowing you to detect anomalies, performance issues, and potential incidents as soon as they occur. Setting up proper monitoring is a vast topic and highly depends on the nature of your infrastructure. Although it's crucial, we won't cover it in detail in this guide due to its scope and variability across different systems.
Establish an On-Call Team and Rotation
Establishing an on-call team and an appropriate rotation is a crucial step in the preparation for incident response. Having a dedicated set of people who are trained and ready to respond to incidents can drastically reduce your response time and prevent escalations.
On-call rotations help prevent burnout by sharing the load among team members, ensuring no one individual is always on duty.
Setting a rotation schedule that suits your team's specific needs can be challenging but is critical to maintain a healthy work-life balance while ensuring coverage.
It's worth noting that how you structure your on-call team and rotations may vary depending on your organization's size, needs, and resources. While we're touching on the basics here, we will dive into the various models of organizing on-call teams in detail in the On-call organization models chapter later in this guide.
Self-serve on-call management
Enable your on-call team with the capability to manage their own schedules and rapidly handover shifts when required. This level of autonomy fosters efficiency and adaptability, ensuring quick adjustments to any changes in circumstances.
Below is an example from the ilert mobile app where you can see your current on-call status and quickly take someone else's on-call.
Have a primary and secondary on-call with automatic escalation
For critical services, always designate both primary and secondary on-call personnel. The secondary person can step in if the primary responder is unable to address the incident, ensuring that there's always someone available to handle emergencies. Set a proper escalation timeout depending on the criticality of the service.
For critical services, we recommend 5 minutes. Also consider a third level of escalation, e.g. your entire team. Below is an example escalation policy with three levels and automatic escalation after 5 minutes.
Consider a follow-the-sun schedule
If your team is globally distributed, consider a follow-the-sun model. This approach allows on-call responsibilities to be passed between time zones, ensuring that your team members handle incidents during their daytime hours, reducing stress and fatigue.
However, the success of a follow-the-sun schedule relies not only on the distribution of team members across various time zones but also on each member's proficiency in handling potential incidents. Each participant needs to have adequate knowledge and technical capabilities to act as an effective responder for the service in question.
In situations where teams themselves are distributed across time zones, and each team member is proficient in maintaining and troubleshooting the system, the follow-the-sun model can be a game-changer.
It ensures that on-call responsibilities are shared more equitably and that incidents are addressed more promptly, ultimately contributing to a better, more reliable service for your users.
The screenshot below shows an example of a follow-the-sun-schedule with a team in the US and a team in the EU.
Integrate monitoring with your alerting tool
Connect your monitoring and observability tools with your alerting and on-call management tool. This integration ensures that when an anomaly is detected, an alert is generated, and the appropriate on-call team member is notified immediately. Below are a few things to consider when setting up alerting:
Keep primary system infrastructure separate from alerting system
Don't let an issue in your primary system infrastructure prevent you from getting the alert. Keeping your primary system infrastructure and alerting system separate ensures that you'll still receive alerts even if your primary system encounters problems.
But separation is only the first step. It's also essential to establish mechanisms that confirm the continuous, seamless communication between your monitoring and alerting systems. One reliable way to do this is by implementing heartbeat monitoring.
In a heartbeat monitoring setup, your monitoring system sends regular "pings" to the alerting system. If the alerting system doesn't receive these pings at the expected intervals, it automatically triggers an alert. This precaution ensures you're immediately notified if there's a disruption between your monitoring and alerting systems, preventing a silent failure from escalating into an unnoticed incident.
Remember, a robust alerting system is only as good as its ability to receive and respond to problems in your primary system. Ensuring separate infrastructures and continuous communication is key to maintaining this vital lifeline.
Setup multiple alerting channels
Ensure your incident response is resilient to internet outages by setting up a minimum of two diverse alerting channels. Begin with push notifications as your primary method; given our near constant access to smartphones, it's an immediate and usually sufficient alerting medium.
Make sure that critical alerts cut through the noise and are not silenced by 'Do Not Disturb' (DND) modes. The ilert mobile app, for instance, supports critical push notifications. These notifications are specially designed to bypass DND settings, ensuring that you're alerted no matter what.
In the event the push notifications fail, switch to more assertive methods like phone calls or SMS notifications. Add all caller IDs from your alerting system to your phone's contact book. Configure these contacts in your phone's settings to bypass DND, ensuring that these critical alerts don't go unheard. The ilert mobile app conveniently syncs and updates these contacts for you, keeping your alerting system well-integrated with your phone.
In this process, it's also vital to incorporate bi-directional alerting channels. This means acknowledging an alert should be as seamless as receiving it, right on the same platform. For example, if you receive a phone call alert, acknowledging it could be as simple as pressing a digit. Once an alert is acknowledged, the system should ensure that it doesn't escalate to your other devices or to other people, preventing redundant notifications.
Alerts should be initiated and repeated every minute until the set escalation time. If no response is recorded after three attempts, the incident should be escalated, signaling your inability to respond.
This multi-channel approach, paired with the right tools, ensures that no critical alert goes unnoticed and the response process remains uninterrupted, regardless of external factors.
Set up a way to report incidents manually
Establish a dedicated hotline for manual incident reporting. This hotline should be capable of forwarding calls to the on-call team according to the on-call rotation.
This not only allows for immediate incident reporting but also ensures that incidents get routed to the right people swiftly. Alternatively, you could enable users to report incidents directly from their daily chat tool.
Using a single system to route both alerts and incoming phone calls to your engineers simplifies the process, reducing confusion, and streamlining communication.
Remember, preparation isn't a one-time event; it's a continuous process. As your systems and teams evolve, your preparation must adapt accordingly.
Regularly review and update your incident response plans and tools to ensure they remain effective and aligned with your current needs and capabilities.
Effective Incident Response
The ability to respond swiftly to incidents is crucial in limiting their potential impact on your services and customers. Empowering your on-call team with the right tools and resources enables them to act immediately and effectively. Here's what you can do to facilitate a swift incident response:
Empower Your On-Call Team
Equip your on-call team with all the necessary information and tools they need to tackle incidents as soon as they occur. This includes up-to-date system information, data from monitoring tools, and access to resources for troubleshooting and resolution.
Facilitate Rapid Containment
Utilize the seamless communication and collaboration features of your incident management tools to ensure rapid containment of incidents. Quick and effective communication leads to swift identification of issues, leading to faster resolution.
Leverage Chat and Collaboration Tools
Make the most of your chat and collaboration tools for coordinating a swift response. These tools allow real-time discussion and brainstorming, fostering effective teamwork in managing incidents. Examples of tools are Slack, Microsoft Teams and Discord.
Create Dedicated Channels and Promote Real-Time Collaboration
For major incidents, establish dedicated chat channels and video conferences. These provide a focused environment for response coordination, stakeholder communication, and status page updates, all without leaving your chat tool.
Encourage your team to use the real-time collaboration feature of your incident management tools. Having everyone in a shared chat room or video conference enables quick discussions, sharing of findings, and coordinated response efforts.
Execute Alert Actions in Chat Interface
Use the chat interface for executing alert actions, from reverting a commit to running diagnostic commands or manipulating infrastructure. This reduces context switching and expedites incident resolution, ensuring that the entire response process can be managed from a single platform.
Prompt and efficient incident response not only limits the impact of incidents but also assures your customers that you're on top of the situation, maintaining their trust and confidence in your services.
Clear Communication During Incidents
Effective communication is crucial during an incident. It's not only about ensuring your team has a shared understanding of the situation but also keeping affected users and stakeholders informed. Here are some strategies to ensure effective communication during an incident:
Proactively Communicate Incidents
Transparency is key in maintaining trust and managing expectations during an incident. By proactively communicating about incidents, your users are less likely to overwhelm your support channels with queries and complaints. Furthermore, transparent communication demonstrates accountability and commitment to resolving issues, which helps build trust with your users.
The screenshot below shows an example of how a status page incident can be created from an alert, informing all subscribers of the status page.
Another way to proactively communicate incidents is directly within your app or service, as illustrated below:
Clear and Timely Updates
Keep everyone updated with timely and clear information about the incident. Regular status updates can reduce anxiety and confusion both within your team and amongst your customers.
Dedicated Status Pages
Create dedicated status pages to provide real-time information about the ongoing incident, including affected services, expected resolution time, and ongoing updates. This gives your users a single source of truth and saves your team from being inundated with queries.
Post-Incident Communication
Once the incident is resolved, communicate the resolution to all affected parties. A post-incident report detailing what happened, how it was resolved, and steps being taken to prevent recurrence can demonstrate your commitment to transparency and continuous improvement.
Communication Training
Provide your team with training on effective communication during incidents. This includes knowing what to say, how to say it, and when to escalate.
Remember, during an incident, communication is as important as the technical response. By ensuring you communicate effectively, you can maintain trust, manage expectations, and minimize disruption for your customers and stakeholders.
Post-Incident Reviews
The end of an incident should be the beginning of learning. ilert's post-incident analysis and reporting tools enable your team to learn from every incident. Comprehensive timelines, response details gathered from chat channels, and resolution times facilitate a deep understanding of areas for improvement. Utilize templated post-mortem reports to share key findings and transform every challenge into an opportunity for growth.
Why conduct Post-Incident Reviews (Post-Mortems)
What are Post-mortems?
A postmortem, or post-incident review is a blameless analysis conducted after an incident to gain a thorough understanding of what went wrong, why it occurred, and how to prevent its recurrence.
During an incident, the team focuses entirely on restoring service; postmortems provide a platform to evaluate actions and strategies after service has been restored.
They allow us to identify strengths, areas of improvement, and strategies to avoid repeated mistakes in the future.
Conducting a postmortem is not a penalty; it's a collaborative process that involves all responders. While the tech team may lead the analysis, the process's ownership lies with a designated individual, ensuring accountability and driving the postmortem to completion.
A postmortem should be conducted after every significant incident, even if the issue was quickly resolved without intervention. The ideal time for a postmortem is soon after the incident while the event's details are still fresh. It serves as the final step of the incident response process, and any delay can hinder critical learning.
By championing a culture of learning and improvement through postmortems, organizations can enhance their infrastructure and incident response process, ensuring they're better equipped for future incidents.
Postmortem Preparation Steps
1. Assign a Responder Owner and set up a meeting
After the resolution of a major incident, the Incident Response Lead promptly assigns one of the responders to oversee the postmortem process. Although the task of writing the postmortem is a collective effort, having a designated owner is crucial for its effective completion.
The postmortem owner is entrusted with several responsibilities, including:
- Scheduling the postmortem meeting
- Investigating the incident (drawing in the necessary expertise from other teams as required)
- Updating the postmortem document
- Creating follow-up action items for preventing a similar occurrence in the future.
To facilitate comprehensive analysis and ensure all perspectives are considered, the postmortem meeting should include the following participants:
- The Incident Response Lead
- Owners of the services involved in the incident
- Key engineers/responders who were involved in resolving the incident
- Engineering and Product Managers for the impacted systems.
The inclusion of these stakeholders encourages a holistic examination of the incident, fostering the cultivation of more robust preventive measures.
2. What happened? Incident Timeline and Impact
After preparing for the postmortem, the next step is to construct a comprehensive timeline of the incident and document its impact.
3. Building the Timeline
Focus on documenting the sequence of events, avoiding any interpretation or judgment about the incident's causes. The timeline should start before the incident's onset and continue through to its resolution, and include significant changes in status or impact, as well as key actions taken by responders.
Review the incident log in your communication tool (e.g. Slack or Microsoft Teams) for crucial decisions and actions. Also include what the team didn't know during the incident that, in hindsight, would have been helpful. You can find this information in monitoring, logs, and deployments of the affected services.
4. Documenting the Impact
Record the impact from multiple perspectives. Detail the duration of the visible impact, the number of customers affected, the number of customers that reported the incident, and the severity of the functional impact.
Quantify impact using a business metric specific to your product. For instance, the effect on API errors, slow performance, or slow notification delivery. If necessary, provide a list of all impacted customers to your support team for further action.
Remember, the goal here is to create an objective, factual record of the incident and its impact. Avoid jumping to conclusions or assigning blame; these steps are purely observational and informational.
5. Root Cause Analysis
Once you have a thorough understanding of the incident's timeline and impact, you'll move onto the Root Cause Analysis (RCA). This stage is to explore the contributing factors that led to the incident, bearing in mind that complex systems don't typically fail due to a singular root cause but a combination of interacting factors.
Monitoring Review
- Begin the analysis by examining the monitoring of the affected services. Look for irregularities like sudden spikes or flatlining when the incident began and leading up to the incident.
- Include relevant queries, commands, graph images, or links from monitoring tools to demonstrate how the data was gathered.
- If monitoring for this service or behavior is absent, include the development of such monitoring as an action item in your postmortem.
Identifying Underlying Causes:
- After understanding superficial causes, delve into why the system was designed to allow such an incident.
- Investigate past design decisions, and examine whether they were part of a larger trend or a specific bug or issue.
Evaluation of Process:
- Consider if the way people collaborated, communicated, and reviewed work contributed to the incident.
This stage is also an opportunity to evaluate and improve the incident response process itself.
Summary of Findings:
- Write a summary of your findings in the postmortem.
Pre-work and documentation are essential to ensure a productive discussion during the postmortem meeting, although additional insights may emerge during the conversation.
Remember, the ultimate goal of the RCA is to uncover the multiple interacting elements that led to the failure and to inform preventative measures for the future.
6. Create Action Items
After determining the causes of the incident, you need to decide what steps should be taken to prevent similar issues from recurring. Although it may not always be feasible or worthwhile to entirely eliminate the possibility of such incidents, it's essential to consider improving detection and mitigation measures for future events. This includes better monitoring and alerting systems and strategies to reduce the severity or duration of incidents.
Create tickets for all proposed actions in your task management tool. Make sure to provide sufficient context and proposed direction for each ticket, so the product owner can prioritize the task and the assignee can carry it out efficiently. Each action item should be actionable and specific.
Create tickets for all proposed actions in your task management tool. Make sure to provide sufficient context and proposed direction for each ticket, so the product owner can prioritize the task and the assignee can carry it out efficiently. Each action item should be actionable and specific.
If any proposed actions require further discussion before creating tickets, add these items to the postmortem meeting agenda. These could be proposals needing team validation or clarification. Discussing these in the meeting will help decide the best course of action.
On-Call Organization Models
Centralized Ops Teams
In this model, a dedicated operations team is responsible for monitoring, alerting, and managing all incidents. They're the first responders to system abnormalities, and they handle the full scope of incident management, from diagnosis to resolution.
Advantages
- This approach involves fewer people, simplifying coordination.
- The team develops a comprehensive understanding of the system's behavior over time, which can aid in identifying anomalies and troubleshooting incidents.
Challenges
- Longer Mean Time To Resolution (MTTR) can occur due to the team's potential lack of deep familiarity with specific software components, especially when complex incidents arise that require specialized knowledge.
- Centralized teams can also become a bottleneck if they are relied upon too heavily. They can also struggle with communication with different teams if not managed effectively.
Ideal Use Case
- This model is recommended when your software is mature, changes infrequently, and system stability is the norm, requiring fewer interventions by the team with deep software-specific knowledge.
Service Teams On-Call
Each service team carries dual responsibility for both development and on-call duties, including incident management for their specific services. This often goes by the DevOps philosophy of "You build it, you run it".
Advantages
- Having the people who built the service also maintain it often leads to faster MTTR. They're familiar with the system intricacies, enabling quicker identification of anomalies and problem-solving.
- This model can also promote better software practices as developers directly experience the operational impacts of their code.
Challenges
- As an organization grows and the number of service teams increases, this model can become complex and challenging to manage, especially with diverse technologies across different teams.
- Being on-call can be stressful and can distract developers from their primary job of building new features.
Ideal Use Case
- This approach is most effective when your software changes frequently. The developers who are implementing these changes are also those managing incidents, leading to more efficient troubleshooting and resolution.
- This model is often used by smaller teams or startups, where developers may wear many hats, including being responsible for maintaining the systems they build.
SRE Teams
In this model, a dedicated Site Reliability Engineering (SRE) team handles operations for each product. SRE teams are professionals dedicated to maintaining system reliability and uptime. This team works closely with development teams, who can be pulled into on-call duties as necessary.
Advantages
- This approach combines the benefits of both previous models. It allows for specialist operational knowledge per product (like in the Centralized Ops model) while also leveraging the in-depth software knowledge of the developers (like in the Service Teams model).
- SRE teams are generally composed of engineers with a deep understanding of the system, allowing them to diagnose and fix problems efficiently. They also focus on creating systems to prevent incidents from happening, which can decrease the overall number of incidents.
Challenges
- The SRE model requires clear roles and responsibilities and strong coordination between the SRE and development teams to be effective.
Ideal Use Case
- This model is popular among mid-sized to large companies that have a significant number of service teams and require dedicated teams to maintain system reliability.
- It provides a balance between specialized on-call teams and the need to involve developers in incident management.
In choosing an on-call organization model, evaluate the unique circumstances and requirements of your organization. Each model offers different strengths, and your choice should reflect your operational needs, team structure, and business objectives. Furthermore, remember that incident management is an evolving process, and the chosen model should be reviewed and adapted over time as your needs change.
