Technical Due Diligence Checklist & 85 Areas for Tech Due Diligence Questions [2024]

This article provides an in-depth view of the most common areas (85 in total) to prepare for before a technical due diligence. It includes checklists for technical due diligence across 85 different areas and explores the top technical questions to explore.

Technical Due Diligence Scope

It’s worth highlighting three pivotal elements - strategy, leadership, and architecture - from the full checklist in this article. Collectively, they ensure a solid base and a great start.


We all know the consequences of companies with a weak strategy or none. We also know the importance of solid leadership, which can make or break a company. The software architecture suitability can significantly hinder an investment or delay the benefit, causing missed opportunities or an inability to compete.


Weakness in any of the top three areas can hinder most investment thesis or require significant investments to mitigate.


  1. Strategy and Roadmap: There has to be a healthy strategy in place. As a business, you bring the subject matter experience and the path ahead. The roadmap process ensures the strategy has legs and can be achieved.

  2. Organization and Leadership: There has to be a solid, collaborative, and cohesive leadership and aligned organization in place.

  3. Software Architecture: The architecture has to align and enable the business strategy. A broken or inadequate architecture or one riddled with technical debt can be severely a handicap to the organization and investment.
