Embracing the resilience imperative: A five-step guide for forward-thinking executives

For executives accountable to business and operational resilience, the mandates are coming—internally and externally. Here’s the path forward.

—

For CIOs, CTOs, and other executives overseeing business and operational stability, the calls for resiliency are coming from inside—and outside—the house. System hiccups erode hard-earned brand equity and lead to customer churn,[1], and investing in reliability is necessary to maintain a competitive edge.[2] Internal mandates to shore up systems against disruption are only increasing,[3] while the General Data Protection Regulation- GDPR[4] and the Digital Operational Resilience Act- DORA [5] add a layer of regulatory complexity.

For the executives we talk to—from the board level to C-suite to senior leadership—there are four pressing issues involving resiliency:

●???? System problems impacting brand reputation and customer experience.

●???? Operational complexity arising from an intricate, interconnected tech landscape.

●???? Increased blast radius due to operational vulnerabilities.

●???? Regulatory compliance around data protection and failover mechanisms.

The stakes are high. Failing to address these challenges can lead to brand damage, absorbed operational risks, and a constant reactive posture.[6] Perhaps most critically, it becomes exponentially more costly to fix these issues down the road rather than tackling them early. The smart money is on getting out ahead of these expectations.

If you try to bring this along later in the life cycle rather than addressing it upfront, you end up with technology sprawl and drift. It becomes much harder to make changes and fix things along the way, especially when you're servicing the business. This maxim echoes across industries, from financial services to healthcare to retail. Proactive resilience is no longer a nice-to-have, but a business imperative.

Executives should consider taking calculated risks and tackling unknowns early

Given these pressures, what's the optimal approach for enterprise leaders? Our research and experience point to taking calculated risks while addressing known issues early. This means looking at technology resilience holistically rather than in silos.

Use an interconnected, tightly coupled approach to tackle known risks upfront instead of waiting. Unknown unknowns require early scenario planning and can be addressed as they arise if we're prepared with a graceful approach (e.g., phased rollouts). Being too reactionary makes it much harder to fix issues down the line. This holistic view requires breaking down traditional organizational silos and fostering collaboration between IT, security, operations, and business units.

The five key trends enabling next-gen resilience

Fortunately, emerging technology trends are enabling more robust approaches to resilience that keep firms from being caught on the back foot. Here are four key developments leaders should leverage.

System Reliability Engineering (SRE) Adoption and Automation: SREs are at the forefront of driving automation and Infrastructure as Code into environments, embedding resilience into the culture of operations. SREs are not just automating processes—they are redefining how reliability is managed by applying engineering principles to IT operations, ensuring that automation is infused with resiliency from the start. By leveraging SRE practices, such as continuous monitoring, automated remediation, and failure injection testing, organizations can reduce manual intervention, increase system robustness, and drive a proactive approach to operational resilience.

Shift to Service Level Indicators/Objectives (SLI/SLO) Frameworks: SLIs and SLOs set clear, measurable targets for system performance and reliability, creating a shared accountability model that aligns product development with operational excellence. This approach, combined with strategic automation and AI-driven methods throughout the software lifecycle, enables earlier issue detection, increased velocity, and improved code quality. By enforcing appropriate controls and baking in quality from the start, organizations can shift from reactive to proactive measures. For example, automated remediation tied to SLOs can trigger corrective actions like scaling infrastructure when performance dips, preventing downtime and maintaining high reliability.

Observability 2.0: Observability is undergoing a significant evolution, moving from basic monitoring to what we refer to as Observability 2.0. While traditional monitoring focuses on predefined metrics, next-gen observability collects rich events and profiles to enable flexible, deep analysis of system behavior integrating with software development life cycle (SDLC).[7] Key capabilities include managing SLOs and error budgets aligned with development lifecycles, focusing on ecosystem hygiene and code quality, and optimizing user experience. This enhanced visibility allows organizations to catch issues earlier, understand complex system interactions, and make data-driven decisions about resilience improvements, ultimately prioritizing investments based on customer experience and business outcomes.

Synthetic data for chaos engineering: As systems grow more complex, synthetic data plays a crucial role in testing system resilience. It allows for comprehensive non-functional testing, such as load and fault injection, without the risks of using real-world data. By leveraging synthetic data, organizations can simulate business processes at scale, uncover hidden edge cases, and safely test under chaotic conditions. This is particularly valuable for regulated industries where compliance concerns restrict the use of real customer data in testing environments.

Self-healing systems: Self-healing systems use smart code designed to degrade, flex, and adapt autonomously to various scenarios, improving resilience without human intervention. This approach leverages coding techniques that enhance code hygiene and integrate algorithms to scale and adjust system behavior dynamically.

By embedding intelligence directly into applications, these systems can predict and address issues proactively through autonomous failovers, graceful shutdowns, and real-time adjustments. This can reduce downtime and minimize disruptions by fixing problems before they are noticed, significantly cutting mean time to recovery. Self-healing capabilities not only boost reliability but also allow IT teams to shift focus from reactive maintenance to strategic innovation.

The way forward: a five-step approach

For executives looking to level up their resilience capabilities, we suggest a three-step approach:

Step one: Identify and prioritize services and dependencies. Start by mapping out critical services and their dependencies across your technology landscape. Understanding which services are vital to your operations and how they interconnect helps prioritize resilience efforts and ensures that key business functions are protected.

Step two: Identify failures and control the blast radius. Proactively identify potential failure points to help minimize impact. This involves designing systems with isolation in mind to contain disruptions, ensuring that issues in one area don’t cascade across the entire operation.

Step three: Define metrics and scale adoption of SLIs/SLOs. Establish clear SLIs and SLOs to measure performance and reliability. These metrics drive the right behaviors, aligning teams around shared goals and helping to scale resilience practices across the organization.

Step four: Address technical debt by prioritizing backlogs and drifts. Regularly review and prioritize your technical debt to manage code drifts and outdated technologies. By actively addressing these issues, you can prevent hidden vulnerabilities from compromising your resilience efforts.

Step five: Build a continuous feedback mechanism to learn and adapt. Implement a feedback loop that captures insights from incidents and operational performance. This mechanism allows your organization to continuously learn, adapt, and refine resilience strategies, fostering an environment of ongoing improvement.

The time to act is now

You're not too late to start, but the time to act is now. While overhauling technology resilience is a continuous journey, there are opportunities to make incremental changes that deliver real impact. These improvements compound over time, creating a virtuous cycle of enhanced reliability, improved customer experience, and reduced operational risk.

Organizations that take a proactive, holistic approach to technology resilience will be better positioned to thrive in an increasingly uncertain and complex business landscape. Those who wait may find themselves perpetually playing catch-up, struggling to meet regulatory requirements, and losing ground to more agile competitors. Technology resilience isn't just an IT issue.
