Quality Debt: Balancing the backlog
Your backlog's full of exciting new features and stakeholders are pushing hard for delivery. Then someone mentions the platform needs upgrading or the code needs refactoring or customers are still working around that incomplete feature from last year.
You know they're right but how do you prioritise those features over the new, exciting ones?
Quality Debt gives Product Owners a business language to talk about these invisible costs so that work can compete fairly for a place in the backlog.
What is Quality Debt?
Quality Debt is whatever robs your team of time developing the product or service. It's the term that helps Product Owners explain why "boring" work matters.
Technical Debt is a familiar concept, coined by Ward Cunningham in 1992 to describe code complexity that slows future development. Quality Debt builds on this idea but broadens it to include all the shortcuts, workarounds and deferred decisions that compound over time.
We categorise Quality Debt into three types that Product Owners need to understand and manage:
Platform Debt - when the underlying platform needs updating. Old versions of operating systems, languages, databases, web frameworks. Outstanding security patches. Outdated encryption protocols. This is foundation work that keeps the system running securely and efficiently.
Technical Debt - mainly coding problems where refactoring would make future changes easier. Usually accumulates after adding features quickly under pressure. Sometimes it means rearchitecting parts of the solution, perhaps splitting functionality into separate services when other business areas want to use them.
Operational Debt - when you as Product Owner have made tough choices to get a release out the door. There's a workaround but it creates an ongoing cost that isn't sustainable in the medium or long term. Customers can create records but not delete them yet. Collaborators within the business are using manual processes. We use the Customer and Collaborator language from our Community Onion RAFT here, since Quality Debt shows up differently depending on who's carrying the cost.
This definition aligns with our Brutal Prioritisation RAFT, where the Should card acknowledges that workarounds have a real business impact.
Even if you delivered a perfect system, entropy ensures all three types will accumulate over time. The question isn't whether you have Quality Debt. It's whether you're managing it deliberately.
Why We Love It
Using language like Quality Debt helps shift the conversation by:
Giving Product Owners business language to explain this quality work to stakeholders.
Making invisible work visible so it can compete with new features in prioritisation.
Framing quality as investment in team productivity, not just "technical overhead”.
Helping compare relative value instead of trying to pin down exact costs.
Breaking the "we'll fix it later" cycle by showing the value that's slipping away the longer it waits.
Preventing the multi-million dollar rebuild that happens when debt compounds for 3-10 years.
When We Use It
We reach for Quality Debt thinking when:
We're coaching Product Owners who struggle to get quality work prioritised.
Teams tell us velocity is dropping but can't explain why to leadership.
We're helping balance quality improvements against new development in roadmaps.
Production incidents are consuming sprint capacity and frustrating everyone.
We need to build a business case for paying down platform or technical debt.
We're working with organisations planning quarterly or annual work allocation.
It's especially powerful when we're helping Product Owners prevent small quality issues from compounding into a crisis that forces a costly rebuild.
How We Do It
We start by making Quality Debt visible, then help Product Owners size how much it's worth fixing.
Draw three columns - Platform Debt, Technical Debt, Operational Debt. We ask the team to brainstorm everything that's slowing them down. No solutions yet, just visibility.
Find the relative value - we look at what’s in the product backlog but also system monitoring for trends, incident reports, support ticket volumes and time spent on workarounds, then use our Relative Sizing RAFT to size how much value paying down the debt would return, against the features competing for the same sprint. Our Value Buckets are a helpful way of understanding the Quality Debt too. Quality Debt often sits in the Reduce Cost buckets, so can be weighed directly against features sitting in the Revenue buckets.
Build the virtuous circle - pay down debt, increase quality, reduce incidents, free up capacity for more valuable work. We coach Product Owners to allocate a sustainable percentage of each sprint or quarter to quality work rather than treating it as a special project.
Make it part of the rhythm - we encourage teams to build monitoring into their Definition of Done, and help Product Owners ask regularly: "How are we doing on Quality Debt? What work would pay that back? What's the cost of leaving it?"
That's it. Simple to see, harder to prioritise and always worth the conversation.
Things to Look Out For
Debt is subjective - what one team sees as critical, another accepts as fine. The conversation matters more than perfect categorisation.
Balance is tricky - teams can swing from all features to all quality and back again. We typically recommend 70-80% new value, 20-30% quality work as a sustainable rhythm.
Some debt is acceptable - a workaround is sometimes genuinely cheaper than building the feature. The goal is conscious management, not zero debt.
Value over precision - translating quality issues into exact dollars or hours is hard and rarely necessary. Sizing debt relative to features, using Relative Sizing or Value Buckets, gets a decision-ready answer faster.
Watch the rebuild cliff - we've seen it repeatedly over 3-10 years. The inertia of "how we've always done it" reaches a point where effective change becomes impossible and that's when multi-million dollar rebuild projects start.
Monitoring isn't optional - you can't manage what you don't measure. Build it into your product from the start, not bolted on later. Our DevOps Quick Assessment RAFT is a good starting point for a concrete measure of where your platform stands today.
Try It With Your Team
At your next sprint or quarterly planning session, run the three-column exercise from How We Do It, then ask: "Which of these is holding back the most value right now?" Prioritise the top three, drop them into your Value Buckets alongside your feature backlog, and commit to addressing at least one next sprint.
