Balancing speed and depth in tech due diligence
July 21, 2025
The Speed vs. Depth Dilemma
- All-in Deep Dive: Comprehensive but time-consuming; risks stalling the deal.
- Rapid Scan: Fast but surface-level; may overlook material risks.
A Structured Scoping Framework
- Module Impact Scoring
- Criteria: Business criticality, complexity, recent changes, exposure to external integrations.
- Score Scale: 1 (low) to 5 (highest).
- Risk Likelihood Assessment
- Criteria: Code churn rate, known vulnerabilities, third-party dependencies.
- Score Scale: 1 (unlikely) to 5 (very likely).
- Effort Estimation
- Criteria: Lines of code, number of services, test maturity.
- Scale: Small (hours), Medium (1–2 days), Large (3+ days).
Time-Boxed Sprints
- High-Priority Modules: Allocate deep-dive sessions (2–4 hours per module).
- Medium-Priority Modules: Conduct rapid checks (30–60 minutes).
- Low-Priority Modules: Surface-level scans or defer entirely.
Best Practices for Execution
- Daily Stand-Ups: 15-minute sync to adjust focus based on emerging findings.
- Mid-Sprint Checkpoint: Re-score modules if new risks surface.
- Final Wrap-Up: Validate that all high-priority areas received sufficient coverage, then draft your report.
Balancing speed and depth isn’t guesswork—it’s a disciplined scoping exercise. By scoring modules on impact and likelihood, then time-boxing your reviews, you ensure critical areas get the scrutiny they deserve without stalling the deal.
