AI can help developers produce code faster without making a team faster at shipping reliable software. The difference is the work after generation: changes still need to be understood, reviewed, built, tested, integrated, and released. If that flow cannot absorb more or larger changes, extra code can mean longer queues rather than shorter delivery times.
Why more AI-generated code may not mean faster delivery
Software delivery is a system, not a typing contest. Generation is only one stage; a change must also pass through feedback and release steps before it creates value for users. A gain at the keyboard can be absorbed by waiting for review, slow builds, test failures, or integration work.

DORA’s 2024 findings show why it is important to look across the system. Google Cloud reported that a 25% increase in AI adoption was associated with a 3.1% increase in code review speed, as well as increases in documentation quality (7.5%) and code quality (3.4%). The same increase was associated with a 1.5% decrease in delivery throughput and a 7.2% decrease in delivery stability. These are estimated associations, not proof that AI adoption caused the changes, and they describe 2024—not a current 2026 prevalence estimate. Google Cloud’s summary of the 2024 DORA report presents the mixed results across these measures.

DORA’s overview describes a possible mechanism: “Because AI allows developers to generate code much faster, it often leads to larger batch sizes, which are slower to review and more prone to creating system instability.” This is a system-level explanation, not a claim that every AI-assisted change is larger or riskier. DORA’s AI capabilities overview also recommends fast feedback loops, automated testing, code reviews, and continuous integration.

Where the work can queue up
Review is visible, but it is only one possible constraint. GitHub’s survey report describes responses from 500 US-based developers at enterprise companies, surveyed with Wakefield Research. Among respondents, 92% said they used AI coding tools at work or in their personal time. Developers reported spending as much time waiting for builds and tests as writing new code; the report also notes delays from code reviews, builds, and tests. These are survey responses from a defined group, not telemetry or a representative census of all software teams. The publication year is not established in the reviewed report excerpt. GitHub’s developer-experience survey report also cautions that code quantity may not correspond to business value.
- Review: A pull request may wait for an available reviewer, or require more effort if it combines many changes or has unclear intent.
- Build and test: Slow or unreliable checks delay feedback and make it harder to distinguish a sound change from a risky one.
- Integration and release: Changes still need to fit together and pass the team’s release controls; faster code generation does not remove those steps.
Which queue matters most depends on the team. DORA’s 2025 report frames AI as an amplifier of organizational conditions: “AI’s primary role in software development is that of an amplifier, magnifying an organization’s existing strengths and weaknesses.” The report draws on more than 100 hours of qualitative data and survey responses from nearly 5,000 technology professionals worldwide. That conclusion argues against assuming one universal bottleneck or prescribing a single tool as the fix. The Google Research record for the 2025 DORA report gives the study context and summary.
How to find your team’s actual bottleneck
Measure the path from a change being started to its safe delivery, not just how quickly code appears. Compare waiting time with active work: a long review queue calls for a different response than a slow test suite or repeated release failures.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors- Review flow: Track time waiting for review separately from time actively reviewing, along with reviewer load and whether changes remain understandable.
- Build and test feedback: Measure how long checks take, how often they fail for infrastructure or flaky-test reasons, and how quickly authors receive actionable results.
- Change size: Observe whether AI-assisted work is arriving in larger, less coherent batches that are harder to assess or integrate.
- Delivery outcomes: Follow throughput and stability alongside quality. DORA’s 2024 associations show that one can improve while another declines.
- Value and trust: Ask whether changes solve a user or business need, remain maintainable, and have enough evidence for the team to trust them.
Pair these measures rather than optimizing one in isolation. For example, a shorter review wait is not a win if it comes from skipping validation, and a higher code count says little about useful delivery. The goal is to identify where work waits and whether the system is shipping valuable changes reliably.
How to keep AI-assisted changes moving safely
Keep changes small and coherent
Break work into changes with a clear purpose and a scope a reviewer can understand. DORA’s overview specifically connects larger batches with slower review and greater instability risk; it does not establish a universally optimal change size. A concise explanation of intent, relevant risk areas, and test evidence helps reviewers focus on the change rather than reconstructing its purpose.
Make review ownership and capacity visible
Route work to people with the relevant context, and avoid sending every change to the same overloaded reviewers. This is a practical response to review queues, not an intervention whose effect these reports quantify. Clear ownership and a visible queue help teams see whether the delay is availability, expertise, or change quality.
Shorten automated feedback loops
Invest in reliable automated tests and continuous integration so authors and reviewers get evidence early. DORA recommends automated testing, fast code reviews, and CI. Faster checks are useful only when they are dependable: flaky or low-signal results can add waiting without improving confidence.
Set clear expectations for validation
Use an acceptable-use policy that explains permitted use cases and addresses privacy and security, as DORA recommends. Make clear what developers must verify, which checks are required, and what context should accompany a proposed change. The policy should support consistent review rather than treating AI-generated code as production-ready by default.
Best Value
Reward useful delivery, not volume
Do not use lines of code or the number of AI-generated changes as stand-alone productivity targets. GitHub’s survey report raises the risk of treating code quantity as business value. Evaluate whether work is useful, maintainable, and delivered reliably, while retaining quality and stability measures.

DORA’s 2024 results are observational associations, so they do not establish that AI alone produced either the positive or negative outcomes. The 39% of respondents who reported little or no trust in AI-generated code is also a 2024 survey finding, not a current estimate of developer trust in 2026. It does, however, underline why verification remains part of the workflow. Google Cloud’s 2024 DORA summary reports both the adoption associations and the trust finding.
The 2025 DORA overview supports a contextual conclusion, not a universal prescription: AI can magnify existing strengths and weaknesses. The available findings do not establish a single best review process, ideal change size, or product that solves routing for every organization. Teams need to locate their own queues and judge improvements by delivery outcomes as well as coding activity.
