How AI-native is your technical organization?

By Tim Vasil • Updated with bottlenecks and codebase readiness

Designed to replace hype and FOMO with empirical rigor, this calculator provides technical leaders with a holistic framework for estimating GenAI-enabled productivity gains across the PDLC. What this calculator doesEstimates how much time AI could save, including work that still needs human attention.Includes time spent reviewing AI output, fixing mistakes, and maintaining the tools.Adjusts for your team’s size, experience, work mix, how paved the AI roadway is, how ready the codebase is for agents, and other responsibilities.Compares your current setup with your target, including the initial slowdown while the team adapts.Shows suggested autonomy ranges and flags choices that may need closer oversight.Highlights the activities holding the most human time, so you can see where moving next buys the most.Links to supporting research and explains the assumptions under “How this is estimated.”Lets you save and share your settings with a link.

Sources

The strongest theme across firsthand accounts from SaaS operators and AI engineering teams: automate execution aggressively, while humans own intent, boundaries, and evidence of success. The disagreement is over how much implementation and review can already be delegated. Highlights mark each source’s key take-away, and the last column records what it actually measured, or what to do about it where it measured nothing.

SourceWhat it saysImpact / Implications
AnthropicAgent evaluationsDemystifying evals, Jan 2026 Evaluate actual outcomes and state changes. Automated checks, production monitoring, and human assessment catch different failures.
  • Give teams ownership of representative evals and continuously improve them from failures.
AnthropicInternal engineering studyHow AI is transforming work, 2025 Engineers report broader output and capability, while most still fully delegate only a minority of their work.
  • +50% self-reported productivity, ≈1.5×, averaged across surveyed engineers and researchers. Internal survey; not experimentally established.
AnthropicOrchestrationEffective agents, Dec 2024 Multi-agent research, Jun 2025 Use simple workflows where possible; parallel agents help when work genuinely separates, with additional cost and coordination.
  • Up to 90% less research time, from parallelizing previously sequential agent execution on complex queries. Not versus human-only work.
Anthropic & OpenAIOversight and permissionsAutonomy research, Feb 2026 Agent guide, 2025 Effective oversight combines visibility, intervention, bounded permissions, and escalation for failures or consequential actions.
  • Grant authority per workflow and risk level; make agents inspectable and interruptible.
Cui et al.Three developer field experimentsResearch paper, 2025 Randomized access to a coding assistant across 4,867 developers increased completed tasks; gains varied across developers.
  • +26.08% completed tasks, ≈1.26× throughput; standard error 10.3 percentage points. Coding assistance, not an AI-native organization.
Demirer, Musolff & YangWriting versus shippingWorking paper, 2026 Across successive tool generations, coding gains attenuate substantially before release. The study uses GitHub activity and AI telemetry.
  • +240% commits, ≈3.4×, cumulative adoption through autonomous agents.
  • +30% releases, ≈1.3×: the same adoption, measured at what ships. Observational estimates, not randomized results or team-wide speed measurements.
DetailAgent-ready codebasesSelf-driving codebases, Sep 2026 The limiting factor for coding agents is the environment they work in, not the model. Where agents cannot exercise integrations end to end, drive the frontend, see the shape of the data, or reproduce a race, they ship bugs there.
  • Track where agents are blind, and close those gaps in the development environment rather than waiting for better models.
DORAROI of AI-assisted software developmentFramework and calculator, 2026 A framework for evaluating AI investment, including the initial productivity dip and the economics of adoption.
  • Use its framework and companion calculator to structure costs, benefits, and assumptions.
DORAOrganizational conditions2025 report AI amplifies existing organizational strengths and weaknesses. Platforms, workflows, and team alignment influence outcomes.
  • Use readiness and delivery constraints to qualify the calculator’s estimates.
GitClearCode quality and productivity researchCode-quality report, 2025 Productivity research, 2026 Churn, duplication, and moved-code trends are maintainability signals. They do not establish that AI caused deterioration or directly measure software shipped. The 2026 study separately examines AI-use cohorts.
  • 4–10× output differences between usage cohorts in the 2026 study, which explicitly questions how much reflects who adopts AI.
JellyfishState of engineering managementSurvey of 636 leaders and practitioners, 2026 Only 10% reported strong enablement and high adoption. AI use varied substantially by activity: writing code 53%, review 49%, specifications 24%.
  • Adoption rates, not a speedup: 10% with strong enablement and high adoption.
Justin McCarthyStrongDMSoftware factory, Feb 2026 Specifications and independently held scenarios drive implementation without human code review. Simulated services enable extensive validation.
  • Explore autonomous delivery where independent validation is strong enough to support it.
Kief MorrisThoughtworksHumans and agents, 2026 Humans build and manage the delivery loop, defining outcomes and improving how agents produce software.
  • Move engineering effort toward architecture, verification, and intervention where judgment matters.
METRTechnical-worker surveySurvey, May 2026 Technical workers report substantial gains, but perceived speed and value differ, and estimates may be overstated.
  • Median 3× self-reported speed.
  • 1.4–2× self-reported value, depending on the question. Convenience sample of 349 technical workers; not causal evidence.
METRExperimental productivity evidenceStudy, Jul 2025 2026 update Early-2025 tools slowed experienced developers on familiar repositories. Later measurement became compromised by selection effects and concurrent agent work.
  • 19% longer task completion in early 2025, ≈0.84× speed.
OpenAI engineeringHarness engineeringAccount, Feb 2026 One team built a new product with agent-written code and predominantly agent-based review. Humans supplied intent and the execution environment.
  • ≈10× development speed; ≈90% less time. The team’s estimate against writing the code manually; one greenfield product, not a controlled comparison.
Tobi Lütke & Farhan ThawarShopifyInterview, 2025 AI adoption needs organizational support: broad access, shared integrations, reusable workflows, and leadership participation.
  • Provide common infrastructure while enabling teams to develop their own applications.
