If you’ve ever been through the motions of an ITIL-driven service review, you know the pain: too many metrics, not enough meaning. Service Level Agreements (SLAs) get signed, filed away, and then resurface during quarterly reviews like time bombs. Everyone nods along, but few really find relevance between the reviews and the day-to-day work. This is because SLAs are contractual and broad by nature.
I frequently speak with customers operating in ITIL-governed environments, and there’s a recurring challenge that surfaces: the gap between ITIL’s high-level operating principles and the practical realities of delivering reliable service day to day. ITIL defines what should be managed, but not how to manage it in real-time. SREs are often left to bridge the gap manually. The conversation naturally turns to how service-level objectives (SLOs) can improve the actual customer experience of these ITIL-managed services.
SLOs are iterative performance targets that define what “good enough” looks like for your users. In software, where perfection isn’t realistic, this question sits at the heart of every reliability and customer experience conversation. SLOs help you cut through the flood of metrics to focus on what actually matters: how well you're meeting user expectations, or how far your performance has drifted off course
This clarity is hard to come by in ITIL environments, where service-level agreements are often broad and static. Everyone should have aspirational goals like “Service X should be available 99.9% of the time.” But setting that goal doesn’t tell you how to get there. It’s like an athlete saying they want to win gold. Sounds great, but what’s the training plan? What are the daily reps, the checkpoints, the early warning signs that things are slipping?
Any great athlete knows the outcome isn’t just about setting a goal. It’s about building a process. Stick to the right plan, track your performance, make adjustments, and the results will follow. The same applies to software reliability. ITIL gives you the high-level vision. SLOs give you the tools to reach it.
SLOs turn that 99.9% target into a living, breathing number tied to real user experience. You can measure burn, set thresholds, and see how performance trends over time. Most importantly, you can act before you miss your goal; instead of waiting for a quarterly review to realize you've drifted too far. You can course-correct in real time.
This transforms ITIL service reviews into real conversations based on actual data: Are we trending in the right direction? What’s burning the budget? Should we revisit our change management approach? It moves the focus away from finger-pointing and toward continuous, proactive improvement.
SLOs are a great solution to the gap that ITIL management leaves. But, without careful oversight and the proper infrastructure, SLOs can land in another siloed dashboard.
Our goal with Nobl9 has been to create something bigger than a system that calculates SLOs. We wanted to create a bridge between reliability theory and the practical reality of running services in complex organizations (and yes, that’s still very much a work in progress and may always be). We operationalized the SLO framework within our product so that you’re not left creating tooling in a void.
With Nobl9, you can:
We’ve also built Nobl9 to complement ITIL-aligned teams wth templates, best practices, and workflows that makes it easy to see the impact of your work. For example, if your organization follows Change Enablement processes, you can use your SLO data within Nobl9 to assess the risk profile of a release. If your error budget is close to exhausted, or you’ve been burning at a high rate, maybe that deployment can wait.
We’ve seen teams across industries face the same core problem: plenty of SLAs, but no clear path to action and achieving the SLA. Moreover, if SLAs don’t directly align with what customers are experiencing, you could be measuring something irrelevant to the user. When you add in service complexity, cross-team dependencies, and regulatory pressure, it gets even harder to see what’s working (or what’s not) until something breaks.
SLOs can serve as the connective tissue between your ITIL-aligned protocols and the day-to-day reliability of your systems.
Take a global e-commerce company with dozens of fulfillment systems and regional data centers. Their IT teams were drowning in SLAs (internal, partner, and customer-facing) and struggling to make sense of what actually mattered. After adopting SLOs through Nobl9, they zeroed in on early-morning inventory syncs as a major pain point. That single insight helped them streamline backend workflows, align team expectations, and reduce incidents by 40% in key services.
Or consider a healthcare software provider serving hospitals across North America. They had compliance boxes checked, but little clarity on which parts of their sprawling platform were most fragile. By layering SLOs onto critical workflows like login and patient search, they cut through monitoring noise and focused on what actually impacted care delivery. After rolling out Nobl9, they defined SLOs on critical workflows and drastically reduced noise in their monitoring systems. As a result, they focused on meaningful alerts, maintained compliance, and improved team morale during incident response.
We’ve seen similar shifts across industries:
These teams have more than tooling in common. They have shifted how they think about service health and managing their systems. Without adding extra complexity in the form of dashboards and charts, the teams within the organization have a shared agreement on what “good” looks like and a plan for what to do when things start slipping.
ITIL is evolving. With ITIL 4, there’s a clear move toward flexibility, continuous improvement, and value co-creation. SLOs fit perfectly into that world. They bring transparency, accountability, and focus to your service level practices. They help your team understand when you’re about to break a promise, before the user ever notices.
If you’re still stuck in the SLA swamp, SLOs (and Nobl9) can help you find peace and clarity in the murky waters. We’ve helped companies large and small get real about service reliability, without unnecessary overhead or extra complexities.
