Full Impact

Time for comprehensive Technical Due Diligence transformation

A thorough technical due diligence covers: code quality and architecture assessment, technical debt quantification (using frameworks like the Product Debt Index), team capability and retention risk, scalability and performance limits, security vulnerabilities and compliance, IP ownership and licensing, AI/ML maturity and cost structure, and operational reliability.

Richard Ewing's R&D Capital Audit is a specialized form of technical due diligence that focuses on the financial implications of technical decisions — treating engineering as a capital allocation problem.

Key questions due diligence answers: Can this technology scale 10x? What is the real cost of technical debt? How dependent is the company on key engineers? Are the stated AI capabilities real or vaporware?

🌍 Where Is It Used?

Technical Due Diligence is implemented across modern technology organizations navigating complex digital transformation.

It is particularly relevant to teams scaling beyond their initial product-market fit, where operational maturity, predictability, and economic efficiency are required by leadership and investors.

👤 Who Uses It?

**Technology Executives (CTO/CIO)** leverage Technical Due Diligence to align their technical strategy with overriding business constraints and board expectations.

**Staff Engineers & Architects** rely on this framework to implement scalable, predictable patterns throughout their domains.

💡 Why It Matters

Technical due diligence reveals hidden risks that financial due diligence misses. Technical debt can cost $1-5M to remediate post-acquisition. Undiscovered architecture limits can cap growth. Key-person dependency can cause post-deal talent loss.

📏 How to Measure

1. **Product Debt Index (PDI)**: Quantifies overall technical debt in dollar terms.

2. **APER**: Revenue per engineer benchmarking.

3. **Technical Insolvency Date**: When debt consumes 100% of capacity.

4. **Innovation Tax**: % of R&D that's actually maintenance.

🛠️ How to Apply Technical Due Diligence

Step 1: Assess — Evaluate your organization's current relationship with Technical Due Diligence. Where is it strong? Where are the gaps?

🚫 Common Mistakes to Avoid

Implementing Technical Due Diligence without executive sponsorship

⚠️ Consequence: Initiatives stall when competing with feature work for resources.

✅ Fix: Secure VP+ sponsor who can protect budget and prioritize the initiative.

Treating Technical Due Diligence as a one-time project instead of ongoing practice

⚠️ Consequence: Initial improvements erode within 2-3 quarters without sustained effort.

✅ Fix: Embed into regular rituals: quarterly reviews, team OKRs, and reporting cadence.

Not measuring Technical Due Diligence baseline before starting

⚠️ Consequence: Cannot demonstrate improvement. ROI narrative impossible to build.

✅ Fix: Spend the first 2 weeks establishing baseline measurements before any changes.

Copying another company's Technical Due Diligence approach without adaptation

⚠️ Consequence: Context mismatch leads to poor results and wasted effort.

✅ Fix: Use frameworks as starting points. Adapt to your team size, stage, and culture.
