Refactoring ideas often stall because they compete with visible feature requests, while the future cost of difficult code is harder to quantify. Give one proposal a fair comparison by tying it to a concrete delivery problem, a likely upcoming change, a bounded first step, and a way to assess the result.
Why refactoring keeps losing priority
Teams have limited engineering capacity. A customer-facing feature or urgent bug usually has an immediate, legible outcome; the cost of leaving difficult code in place is less visible until someone has to change it. In a 2019 study based on a survey of 17 practitioners and follow-up interviews, technical-debt work was often handled reactively, kept in a “shadow backlog” outside the official sprint backlog, and hampered by limited quantitative information about individual debt items. The study’s findings describe its participants, not every engineering organization.

The term “technical debt” can also fail to communicate a shared business case. A 2015 Carnegie Mellon Software Engineering Institute summary of a survey of 1,831 participants—primarily engineers and architects working on long-lived projects at three large organizations—reported that 65 percent had no defined technical-debt management practice, 25 percent managed it at team level, and 60 percent tracked it through risk processes or backlog grooming. In the same study, 42 percent said executives and business managers were largely unaware of technical debt; 10 percent said business managers actively managed it. These figures are specific to that study’s population, not universal industry rates. The SEI summary illustrates why an engineer’s concern may not arrive in a form that product or business stakeholders can weigh against roadmap work.

Debt is not just messy code or a high count of lines. It can arise from design and architectural choices that make later changes more costly. Neil Ernst’s SEI article presents Steve McConnell’s working definition: “A design or construction approach that is expedient in the short term but that creates a technical context in which the same work will cost more to do later than it would cost to do now (including increased cost over time).” The article also quotes Ipek Ozkaya, speaking at the 2012 Agile Research Forum: “A little debt speeds up development, and can be beneficial as long as the debt is paid back promptly with a rewrite that reduces complexity and streamlines future enhancements.” The condition matters: not every shortcut must be repaid immediately, and debt is useful to discuss in terms of its effect on future work.

Even when a team agrees there is a problem, refactoring can look expensive and risky. A Microsoft field study reports that developers perceived substantial cost and risk in refactoring. Its analysis of Windows 7 version history found that among the top 5 percent of preferentially refactored modules, inter-module dependencies and several complexity measures decreased, while size increased relative to the bottom 95 percent. That result argues against treating “smaller code” as the only proof of success; it does not establish that every refactor improves productivity. The study’s findings support evaluating changes across relevant dimensions.
Turn one cleanup request into a decision brief
Bring the proposal into the normal prioritization discussion with enough context to compare it with customer-facing work. The format below is a practical synthesis of the documented barriers, not a method tested by the cited studies.
1. Locate the friction
Name the module, service, or architectural seam. Give a concrete example from recent work: for instance, a change that required touching several dependent components, repeated edits in multiple places, or an awkward workaround. Avoid calling an area “bad” or “messy” without showing what that means for delivery.

2. Describe the delivery cost
Explain the consequence in terms the team can assess: repeated change effort, defect risk, operational friction, or difficulty delivering a specific feature. Use observed examples where available. Do not turn a plausible benefit into invented hours saved or incident reductions.
3. Explain why now
Identify the next likely feature, recurring work pattern, or operational need that will touch the area, and when it is expected. If no likely change is on the horizon, say so. A refactor justified only by abstract neatness may reasonably lose to more immediate work.
4. Bound the first step
Propose a small, reviewable change with clear scope and dependencies. A broad rewrite should not be presented as a low-risk cleanup. State what is included in the first step and what remains outside it, so the team can judge its cost and exposure.
5. Choose a validation signal
Say how the team will tell whether the change helped. Depending on the problem, that could mean fewer inter-module dependencies, a simpler change path, fewer repeated defects, or better ability to deliver the named feature. Choose signals that fit the proposal; one metric is not a universal predictor of return, and different measures can move in different directions.
Compare the proposal with feature work
Use a few explicit axes rather than pretending every candidate can be reduced to a precise score. A customer-impacting issue may deserve priority over a larger cleanup if the cleanup is unlikely to affect near-term work.
| Axis | Question to ask |
|---|---|
| Delivery friction | What repeated effort, defect exposure, or operational obstacle is this expected to remove? |
| Likelihood and timing | How likely is work in this area, and when is the next known change expected? |
| Scope and risk | How bounded is the first step, what does it depend on, and what could it disrupt? |
| Validation | What observable signal will show whether the change improved the relevant path? |
Discuss these axes alongside the feature’s customer impact, urgency, and delivery needs. The studies document tradeoffs and gaps in quantitative information; they do not validate a universal scoring formula. A number that looks precise is not useful if the team cannot explain how it was derived.
What a credible proposal sounds like
“The account configuration service is touched by the permissions change planned for next cycle. The last two changes required edits in three dependent modules, and one dependency is the reason this proposal targets that seam. I propose extracting the permission check behind one interface first; this does not include rewriting the service. We’ll review the dependency count and whether the planned feature can change the permission path in one place.”
This example makes a location, delivery connection, timing, bounded step, and validation signal explicit. Replace its details with evidence from your own codebase; do not copy its measurements or assume the same scope is appropriate.
