Risk Evaluation in the Age of AI-Aided Development
Engineering teams have always made judgment calls about risk and speed. With AI development tools becoming standard practice, that judgment call has gained a new dimension demanding more careful consideration.
The Traditional Risk Equation
Before AI tools entered the picture, risk evaluation in software development was already a balancing act. Consider a straightforward example: building a new web page using existing APIs. This is typically low-risk work. If something goes wrong, the business impact is contained. You can iterate quickly without catastrophic consequences.
Even for low-risk features, smart teams use de-risking mechanisms:
- Create the new page without adding it to navigation menus
- Share a direct URL for internal testing with real data
- Duplicate and refactor instead of modifying in-place
- Deploy to staging environments first
Backend changes and database modifications sit on the opposite end of the risk spectrum, carrying higher business impact when they fail. De-risking here looks different: feature flags, environment variables, staged rollouts, and thorough review processes.
This risk evaluation has always determined our development approach. How much peer review do we conduct? How detailed are our PRDs? How much architectural planning happens upfront? These decisions trade speed against thoroughness, with the stakes determined by the risk level of what we're building. Understanding which project risks to tackle first helps teams prioritize their uncertainty management efforts.
AI Development Adds Another Tier
AI-aided development tools create a new tier in this risk evaluation framework. According to Stack Overflow's 2025 Developer Survey, 63% of professional developers now use AI in their workflows, making this shift unavoidable rather than optional. You can now offload work to an AI agent, but with varying levels of oversight:
Lower Risk Path:
- Generate a detailed PRD
- Review the PRD with the AI tool
- Make smaller, incremental commits
- Revise and refine iteratively
(Managing requirements across multiple sources becomes easier when you leverage AI tools to consolidate project context.)
Higher Speed Path:
- Provide the AI with a JIRA ticket
- Accept the generated code with minimal review
- Ship quickly to appropriate environments
The critical question becomes: how thoroughly do you review AI-generated code before it reaches production? For backend or database changes, thorough human review remains essential. For lower-risk features like prototypes, your tolerance for shipping lightly reviewed code increases. This isn't reckless. It's a calculated decision based on context.
This Isn't New, It's Evolved
The fundamental judgment call hasn't changed. We've always balanced development speed against risk. Before AI, you could accept limited additional risk for speed: using a new framework without deep expertise or reducing review cycles for time-sensitive features.
AI development tools extend this spectrum dramatically, letting you accelerate development even further while accepting a different kind of risk: code that may not have been fully reviewed by a human developer. Research from GitHub and Accenture demonstrates developers complete tasks 55% faster with AI assistance, validating the speed gains.
Yet developer confidence is cratering. The Stack Overflow survey found trust in AI accuracy dropped from 40% in 2024 to just 29% in 2025, while 66% report spending significant time fixing code that's "almost right, but not quite." The speed is real. So is the erosion of confidence.
The Tech Debt Reality
This additional risk comes with a real price tag: technical debt at scale. GitClear's analysis of 211 million lines of code from 2020 to 2024 reveals alarming patterns. Code clones (duplicated code blocks) increased four-fold during this period. Code refactoring collapsed from 25% of changed lines in 2021 to less than 10% in 2024. Meanwhile, research from Apiiro found that teams using AI coding assistants achieve 4x velocity improvements but introduce 10x more vulnerabilities.
Let that sink in. Four times more duplicated code. Half as much refactoring. This isn't about messy formatting or style inconsistencies. This is about creating maintenance nightmares where you fix the same bug in four different locations, where architectural improvements become prohibitively expensive, where technical debt compounds faster than your team can pay it down.
The speed gains are seductive. The long-term costs are brutal. Many teams focus on incident response speed without addressing the upstream processes that create problems in the first place. AI-generated code that looks functional today can introduce subtle architectural issues that multiply into production incidents months later.
This doesn't mean avoiding AI tools. It means acknowledging that the risk you accept today for a "quick prototype" will haunt your codebase tomorrow. For genuinely disposable code, that's acceptable. For production systems with multi-year lifespans, you need radically different standards.
Security Remains Non-Negotiable
Accepting more risk for development speed does not mean skipping security checks. AI-generated code can introduce vulnerabilities that aren't obvious in functional testing. Your CI/CD pipeline must catch these automatically through security scanning, static analysis, and dependency checks. Don't trade security for speed, even for prototypes that might evolve into production features.
Practical Guidance
When evaluating risk with AI-aided development:
For Low-Risk Features:
- New UI pages without complex business logic
- Internal tools and admin interfaces
- Prototype features you're testing for product-market fit
- Documentation and content generation
Accept faster AI development with lighter review. Use de-risking mechanisms like hidden pages and staged rollouts, but still run security scans and static analysis.
For High-Risk Changes:
- Database schema modifications
- Authentication and authorization logic
- Payment processing and financial transactions
- Core business logic and algorithms
Maintain rigorous review standards. AI can draft the code, but human expertise must validate it thoroughly. Security scanning and static analysis remain mandatory, not optional.
For Everything In Between:
- Assess the blast radius if something fails
- Calculate the real cost of fixing issues in six months when context is lost
- Evaluate honestly whether your team can understand and maintain AI-generated code
- Review AI output more carefully for domains where the tool has shown weaknesses
- Always run automated security checks regardless of feature risk
Understanding whether your team members thrive as generalists or specialists helps you match AI-assisted work to the engineers who can review it effectively.
The Bottom Line
Here's what the data tells us: 63% of developers now use AI tools and I expect this to only go up. Developer confidence in those tools dropped from 40% to 29% in a single year. Code duplication quadrupled. Refactoring was cut in half. Two-thirds of developers are fixing AI-generated code that looked right but wasn't.
This isn't a crisis. It's a signal. AI development tools are powerful accelerators that come with hidden costs we're only beginning to measure. The teams that thrive won't be the ones who ship fastest. They'll be the ones who understand exactly when to accept AI-generated code and when to demand human expertise.
Use AI tools for what they excel at: accelerating low-risk development, generating boilerplate, prototyping quickly. Reject them for what they struggle with: architectural decisions, security-critical code, complex business logic. And never, under any circumstances, skip automated security scanning because you trust the AI output.
The speed is seductive. The technical debt is real. The judgment call is still yours.
