Partner

Shared risk, shared expertise. Combine internal capability with external specialization.

01 - The Trade-Offs

Each path has real costs

There's no free lunch. Building gives you control but requires sustained investment. Buying is faster but creates dependencies. Partnership balances both but requires coordination.

Factor Build Buy Partner
Time to value 12-24 months 1-3 months 3-6 months
Upfront cost $2-5M+ $50K-500K $200K-1M
Ongoing cost $500K-2M/year $100K-1M/year Variable
Customization Unlimited Limited High
Talent required 10-25 FTEs 2-5 FTEs 5-10 FTEs
Vendor risk None High Moderate
IP ownership Full None Negotiated

The Real Question

Don't ask "should we build or buy?" Ask "what is our sustainable competitive advantage and where should we invest our best people?"

Build what differentiates you. Buy what doesn't. Partner when you need to move fast but want optionality.

04 - Case Studies

How organizations decided

Financial Services - Chose Build

Tier-1 Bank: AI Risk Management

Built in-house because model risk management is core to competitive position. 18-month build, $4M investment, now differentiator in regulatory examinations. Right choice: risk management expertise became a moat.

Healthcare - Chose Buy

Regional Health System: Clinical Documentation

Bought commercial AI scribe solution. Not a differentiator - all competitors need it. Deployed in 6 weeks at $200K/year. Right choice: freed resources to focus on patient care innovation.

Insurance - Chose Partner

National Carrier: Fraud Detection

Partnered for initial implementation with knowledge transfer agreement. Uncertain requirements, regulatory complexity, needed to move fast. Partnership reduced risk while building internal capability over 12 months.

05 - Decision Checklist

Questions to ask before deciding

Question If Yes...
Is this capability core to our competitive advantage? Build or Partner with IP transfer
Do we have the talent to build and maintain this? Build is feasible
Is time-to-market critical? Buy or Partner
Are requirements well understood? Buy is lower risk
Do we need to move fast but keep options open? Partner with optionality
Is regulatory compliance complex? Partner for expertise
Will vendors have ongoing leverage over us? Build or Partner
Is this a commodity that all competitors need? Buy - don't over-invest
