Build vs. Buy: Comprehensive Decision Framework

Internal Development Approach (Build)

Primary Advantages:

• Full control: Complete ownership over data, ML models, and product roadmap
• Custom alignment: Features precisely tailored to brand requirements
• No vendor dependencies: Eliminates recurring license costs and vendor lock-in
• Deep integration: Seamless connection with proprietary systems

Critical Challenges:

• Significant investment: $500K–$2M+ upfront for enterprise-grade capability
• Extended timeline: 12–18 months to go live (slower time-to-value)
• Ongoing staffing: Continuous dev/ML ops personnel requirements
• Scaling complexity: Multi-region and multi-language implementation challenges

Enterprise AI Vendor Partnership (Buy)

Strategic Advantages:

• Rapid deployment: Go live in 2–6 months—accelerated ROI realization
• Proven solutions: Field-tested algorithms and industry best practices
• Continuous innovation: Vendor-managed improvements and compliance updates
• Expert support: Access to specialized knowledge base and ongoing assistance

Implementation Considerations:

• Recurring costs: Monthly/annual license fee structure
• Customization limits: Less "from scratch" modification capability
• Vendor dependency: Potential risk of vendor lock-in scenarios
• Integration variables: Complexity depends on existing stack and vendor APIs
