Gain insight into our Enterprise Resilience Engineering Framework and how it can help your business adapt and thrive in today's ever evolving technology landscape.
Technology resilience is the ability of a system to continue operating and recover swiftly under adverse conditions. Resiliency has become more crucial as we navigate an era marked by increasing complexity—due to distributed architectures, multihybrid cloud environments, interconnected systems, and thousands of microservices.
Challenges such as perpetual technical debt, rigid systems, shifting regulations, organizational complexity, technology disruptions, and delivery friction create significant gaps. The shift-left culture, new regulatory requirements (for example, DORA,¹ SEC,² OCC,³ and FFIEC⁴) and a changing regulatory ethos add complexity to resilience, necessitating a balance between regulatory and market-driven solutions. Additionally, the shared responsibility model with third parties such as vendors and hyperscalers—along with heightened customer expectations for “always-on” services—further complicates matters.
Resilience failures now carry severe consequences, potentially leading to competitive disadvantages and loss of customer trust. A recent faulty software update caused a major information technology (IT) outage⁵ worldwide, disrupting operations across sectors such as banking, airlines, and hospitals. This incident highlights the vulnerability of our interconnected world and the fragility of our technological environment.
Our resiliency engineering reference framework provides valuable guidance for building robust mitigation strategies, ensuring operational continuity during challenging times. The framework fosters a proactive resilience culture—extending beyond mere availability and data protection—to emphasize preparedness and adaptability across architectural and operational pillars (figure 1).
Leaders must proactively mitigate resiliency problems to build reliable and robust systems and reduce the cost of fixing issues. By enabling organizations to assess their current state and embrace resilience improvement opportunities such as implementing architectural patterns to remediate failures, executing game days, and ingraining a “resiliency-first” culture over time, they can start to build resilience today.
Achieving proactive resilience may seem daunting, but a reference framework can help organizations navigate challenges with confidence and adaptability. Ultimately, proactive resilience flips the script, driving businesses to thrive in an unpredictable world.
At Deloitte, we thoughtfully assess design resilient architecture for critical systems. We recognize that resilience is the backbone of robust systems, enabling them to withstand and recover from unexpected failures.
By embracing these practices, we assist organizations in transitioning to modern operations, enabling them to harness real-time insights and effectively manage error budgets. This proactive mindset is crucial in safeguarding customer trust and maintaining organizational integrity in an unpredictable world.
One of our clients faced significant reliability challenges with regular outages and needed to prepare for an influx of millions of new transactions on its platform. Despite establishing incident management processes, resiliency knowledge and skills gaps posed substantial challenges. The client sought our partnership to embark on its resiliency-bolstering journey.
By leveraging our resiliency engineering reference framework, we empowered our client to adopt engineering practices, enhance IT resiliency, and seamlessly prepare for increased traffic significantly. This transformation included:
Through proactive measures such as FMEA and chaos testing, we identified potential faults before they became issues. We also published resiliency software standards and upskilled teams to foster a culture of resilience.
Incidents were reduced by 25%, duration of major incidents was reduced by nearly 30%, more than 400 failure modes were identified, and 60 of them were remediated across more than 100 critical path applications. These efforts collectively contributed to enhancing system reliability and fostering a resilient organizational culture. This proactive approach ensured that our client was well-prepared to handle the increased customer base and maintain operational continuity.
By collaborating with us and leveraging our Resiliency Engineering Reference Framework, the company mitigated most of its stability risks and built a robust foundation for future growth and stability.
