Just came from the most sobering panel of SF Tech Week: âEnterprise AI: From POC to Production.â
Four enterprise CTOs. All deploying AI at scale. All with horror stories.
The Stat That Shocked the Room
âLess than 20% of AI initiatives are scaled across the enterprise.â
Source: EPAM study, confirmed by all 4 panelists from their own experience
Translation: 80% of AI projects FAIL to reach production.
Not fail because the technology doesnât work. Fail because of organizational, technical, and cultural barriers.
The âAI POC Successâ Trap
Hereâs the pattern every panelist described:
Phase 1: POC Success
- Pick a well-scoped use case
- Use GPT-4 or Claude API
- Build a demo in 2-4 weeks
- Show impressive results
- Executive sponsors excited
Phase 2: Production Reality
- Try to integrate with enterprise systems
- Hit data quality issues
- Discover compliance requirements
- Realize infrastructure doesnât scale
- Security review kills the project
One CTO called it: âDeath Valley between POC and Productionâ
The 5 Barriers to Production AI
From the panel + supporting research:
1. Legacy System Integration (60% cite this as top barrier)
The POC:
- Demo works on clean CSV data
- No system dependencies
- Runs on someoneâs laptop
Production reality:
- Data in 15 different systems (SAP, Salesforce, Oracle, custom databases)
- No APIs, only batch file exports from 1995
- Data format inconsistencies
- Need real-time sync but systems donât support it
Panelist quote: âOur POC worked perfectly. Then we found out the data we needed was in a mainframe from 1987 that nobody knows how to access anymore.â
2. Data Quality and Availability (50% of companies)
The POC:
- Hand-curated sample data
- Edge cases removed
- âRepresentativeâ subset (actually: cleaned and perfect)
Production reality:
- Missing data (30% of fields null)
- Inconsistent formats (dates in 7 different formats)
- Duplicate records
- Contradictory data across systems
- Historical data needed for training doesnât exist
Data quality rule: POC uses top 10% cleanest data. Production requires handling bottom 90%.
3. Skills Gap (40% lack AI expertise)
The POC:
- External consultants or ML engineers build it
- Data scientists fine-tune the model
- Proof of concept doesnât need maintenance
Production reality:
- Need engineers to maintain it (consultants are gone)
- IT team doesnât understand ML (canât debug when it breaks)
- Data drift happens (model accuracy degrades)
- Nobody on staff can retrain or update models
Hiring challenge: 43% of companies plan to hire AI roles in 2025, competing for same small talent pool.
Most in-demand roles:
- Machine learning engineers
- AI researchers
- ML ops engineers
- AI ethics/governance specialists
4. AI Governance and Compliance (18 months to implement)
The POC:
- âDonât worry about compliance for the demoâ
- Skips security review
- No audit trail
- No bias testing
Production reality:
- Legal requires AI risk assessment (new process, takes 3 months)
- Compliance requires model explainability (black box = blocked)
- Security requires penetration testing of AI components
- Privacy requires data minimization and consent
- Regulations (EU AI Act, state laws) require documentation
Average time to implement AI governance: 18 months
From idea to AI governance framework in place = year and a half.
5. Cost at Scale
The POC:
- 1,000 API calls to GPT-4
- Cost: $50
- âTotally affordable!â
Production reality:
- 10 million API calls/month
- Cost: $500,000/year
- CFO: âAbsolutely notâ
Need to:
- Optimize prompts (reduce tokens)
- Switch to smaller models (lose quality)
- Self-host open source (infrastructure complexity)
- Implement caching (engineering effort)
One panelist: POC to production = 23x cost multiplier after accounting for all infrastructure, tooling, and engineering.
Real Enterprise AI Production Stories
Success Story: Financial Services Company
Use case: Automated document processing for loan applications
POC (4 weeks):
- GPT-4 API extracts data from PDFs
- 95% accuracy on test set
- Stakeholders thrilled
Production journey (14 months):
- Month 1-3: Security review (data canât leave premises â need self-hosted model)
- Month 4-6: Infrastructure build (GPU cluster, ML ops platform)
- Month 7-9: Model fine-tuning (open source model to match GPT-4 accuracy)
- Month 10-11: Integration (connect to 8 legacy systems)
- Month 12-14: Compliance (audit trail, explainability, testing)
Final cost:
- POC: $5K
- Production: $800K first year (infrastructure + engineering)
Result: Successful deployment, processes 50K documents/month, saves $2M/year in manual labor
ROI positive after 6 months in production
Failure Story: Healthcare Company
Use case: AI-powered patient diagnosis support
POC (6 weeks):
- LLM analyzes patient records, suggests diagnoses
- Doctors love it in trials
- 85% accuracy vs expert human
Production attempt (failed after 9 months):
- HIPAA compliance blocked cloud AI APIs
- Self-hosting required (security review takes 4 months)
- Model explainability insufficient (doctors need to know WHY AI suggested diagnosis)
- Liability concerns (whoâs responsible if AI is wrong?)
- Integration with EHR system impossible (vendor wonât provide API)
Result: Project cancelled, $1.2M spent, zero production deployment
Lesson: Some use cases arenât ready for AI (regulatory/liability too high)
The 30% Who Succeed: What They Do Differently
IBM study: 30% of tech-advanced companies successfully implemented AI at scale
What separates success from failure:
Start with infrastructure, not use cases
- Build ML ops platform first
- Establish data pipelines
- Create governance framework
- THEN identify use cases
Choose low-risk, high-volume use cases
- Not âAI diagnosisâ (high risk)
- Yes âemail triageâ (low risk)
- Focus on efficiency, not critical decisions
Invest in change management
- Train employees on AI tools
- Address âAI will replace meâ fears
- Create AI champions in each department
Plan for the whole lifecycle
- POC budget: $10K
- Production budget: $500K-2M (50-200x multiplier)
- If you canât afford production, donât start POC
Hybrid approach
- Use APIs for low-volume, low-risk
- Self-host for high-volume, high-sensitivity
- Donât go all-in on one strategy
The Questions Iâm Taking Back to My Team
Weâre mid-size company (500 employees), evaluating AI deployment.
Based on this panel, hereâs my new checklist before starting ANY AI project:
Before POC:
- â Do we have executive sponsorship + multi-year budget?
- â Have we assessed data quality and availability?
- â Do we have (or can we hire) ML engineering talent?
- â Is our infrastructure ready (or can we build it)?
- â Have we identified compliance requirements upfront?
- â Can we commit to 12-18 month timeline?
- â Is the ROI worth the investment (realistic production cost)?
If answer to ANY question is âno,â we shouldnât start the POC.
POC-to-production checklist:
- â Integration plan with all systems (documented before POC)
- â Data quality assessment (measure completeness, accuracy)
- â Compliance review completed (legal, security, privacy)
- â Production cost model (realistic, not POC costs)
- â Team trained (not relying on consultants)
- â Monitoring and observability plan
- â Model governance (versioning, retraining, rollback)
My Controversial Take
Hot take from the panel (everyone nodded):
âMost companies should NOT be building custom AI models. Use off-the-shelf AI products instead.â
Instead of:
Building custom LLM application from scratch
Fine-tuning open source models
Hiring ML team
Consider:
Buying AI-enabled SaaS products (Salesforce with Einstein, Microsoft with Copilot)
Using AI APIs for specific tasks (OpenAI, Anthropic, Cohere)
Partnering with AI consultancies for specialized use cases
When to build custom:
- AI is your core competitive advantage
- Unique data gives you proprietary edge
- Volume justifies infrastructure investment (>$500K/year in API costs)
When to buy:
- AI is supporting tool, not core business
- Standard use cases (email, documents, customer support)
- Small/mid-size company (<1000 employees)
Questions for This Community
For CTOs/engineering leaders:
- Whatâs been your POC â production success rate?
- Whatâs your biggest barrier (integration, skills, cost, compliance)?
- Are you building or buying AI?
For ML engineers:
- How do you convince leadership that production is 10-50x harder than POC?
- Whatâs your ML ops stack look like?
For everyone:
- Is the 20% success rate acceptable or is enterprise AI fundamentally broken?
Iâm trying to avoid becoming part of the 80% failure statistic.
