In the world of resilience planning, the concept of Recovery Time Objectives (RTOs) has long been the standard for measuring how quickly systems or processes must be restored after a disruption. While RTOs have their place, I’ve increasingly found them to be too rigid, arbitrary, and often disconnected from the realities of modern business operations. This realization led me to adopt a new approach: using percentage availability metrics to measure and plan for resilience.
Here’s why I’ve started focusing on percentage availability and how it can transform the way organizations think about operational reliability and resilience.
The Problem with RTOs
RTOs attempt to define the maximum acceptable downtime for a system or process, but they often fall short in practical application:
In today’s fast-paced and interconnected business environment, organizations need a more dynamic, relatable, and actionable metric.
Why Percentage Availability Metrics Make Sense
Percentage availability shifts the focus from “how fast can we recover?” to “how reliable is this system over time?” It measures the proportion of time a service or function is accessible and operational over a given period, typically a year. For example:

Integrating Percentage Availability into Resilience Planning
Here’s how percentage availability can be woven into an organization’s resilience planning framework:
1. Setting Availability Targets
2. Guiding Response Strategies
3. Enhancing Playbooks
4. Measuring and Refining
Real-World Example: A Customer-Facing Application
Imagine a company managing a high-traffic e-commerce platform. The application’s availability target is set at 99.9%, allowing for no more than 8.76 hours of downtime annually. Here’s how they planned and executed their resilience strategy:
The result? The organization consistently met its availability target, maintaining customer trust and avoiding revenue loss.
The Future of Resilience Metrics
As organizations face increasingly complex disruptions, resilience planning must evolve. Percentage availability metrics offer a practical, forward-thinking alternative to traditional RTOs, emphasizing reliability and aligning resilience efforts with business goals.
By shifting to this approach, we can:
Let’s rethink how we measure resilience and embrace a future where availability isn’t just a goal, it’s a standard.
