The Executive's 90-Day Guide to ChatGPT Enterprise

Richard Casemore - @skarard
Why This Matters Now
Your competitors are already using it. McKinsey estimates generative AI could add $4.4 trillion annually to the global economy. The question isn't whether to adopt—it's how fast you can move.
This guide gives you a practical 90-day roadmap.
Week 1-2: Executive Immersion
Before rolling out to your organization, you need hands-on experience.
Your First Tasks
- Sign up for ChatGPT Plus ($20/month) to experience the consumer product
- Use it daily for real work tasks:
- Draft emails and memos
- Summarize lengthy reports
- Brainstorm strategic options
- Prepare meeting talking points
- Document what works and what doesn't
Key Insight
You can't lead an AI transformation without personal fluency. Executives who skip this step make poor deployment decisions.
Week 3-4: Enterprise Evaluation
Contact OpenAI Enterprise Sales
ChatGPT Enterprise offers:
- SOC 2 compliance
- Data not used for training
- Admin controls and SSO
- Higher rate limits
- Advanced analytics
Questions to Ask
- What's the pricing model for our employee count?
- How does data handling comply with our industry regulations?
- What admin controls are available?
- Can we customize for our specific use cases?
Internal Stakeholder Alignment
Brief these leaders:
- CTO/CIO: Technical integration requirements
- CISO: Security and compliance review

- CFO: Budget and ROI expectations
Week 5-6: Pilot Design
Select 2-3 Pilot Groups
Choose departments where:
- Tasks involve significant writing/analysis
- Staff are relatively tech-savvy
- Results are measurable
- Leadership is supportive
Good candidates: Marketing, Legal, HR, Strategy
Define Success Metrics
Before launching, establish:
- Time saved per employee per week
- Quality assessments (blind comparisons)
- Employee satisfaction scores
- Specific task completion rates
Create Usage Guidelines
Document clear policies:
- What data can be input (never confidential client info initially)
- Review requirements for AI-generated content
- Disclosure rules (when to reveal AI assistance)
- Escalation paths for concerns
Week 7-10: Pilot Execution
Launch with Training
Don't just give access—provide:
- 2-hour hands-on workshop
- Prompt engineering basics
- Department-specific use cases
- Office hours for questions
Gather Feedback Weekly
Short surveys asking:
- What tasks are you using it for?
- What's working well?
- What's frustrating?
- What do you wish it could do?
Iterate Rapidly
Adjust guidelines and training based on feedback. Common early issues:
- Outputs too generic (need better prompts)
- Compliance concerns (need clearer boundaries)
- Uneven adoption (need peer champions)
Week 11-12: Measure and Decide
Quantify Results
Compare pilot groups to control groups:
- Productivity metrics
- Quality assessments
- Employee satisfaction
- Cost per task
Build the Business Case
Create an executive summary covering:
- Pilot results with specific numbers
- Projected organization-wide impact
- Implementation costs and timeline
- Risk mitigation approach
Make the Go/No-Go Decision
With data in hand, decide:
- Full deployment
- Expanded pilot
- Pause for more evaluation
Beyond 90 Days: Scaling Up
If proceeding to full deployment:
Phase 1 (Months 4-6): Department Rollout
- Prioritize high-impact departments
- Train department champions
- Build prompt libraries for common tasks
Phase 2 (Months 7-9): Organization-Wide
- All employees with appropriate access
- Advanced training for power users
- Integration with existing workflows
Phase 3 (Months 10-12): Optimization
- Custom GPTs for specific functions
- API integrations with internal systems
- Advanced analytics and ROI tracking
Common Pitfalls to Avoid
Moving too slowly: Competitors aren't waiting Moving too fast: Skipping security review creates risk Insufficient training: Untrained users get poor results No clear guidelines: Ambiguity creates compliance issues Ignoring change management: Technology without adoption is waste
The Bottom Line
