Due Dilligence – M&A

Basic points:

  • What will it take to modify and add new functionality
  • Maintainability and automated testing
  • Scalability risks and strengths
  • System design, code size, technologies, and complexity
  • Open source and other dependencies
  • Security and privacy risks
  • Development capability, data center practices
  • Defect/incident analysis
  • Sophistication and robustness of algorithms and data models
  • Internationalization, portability, or other quality attributes
  • Your specific questions

Another view of points (from http://www.crosslaketech.com/technical-due-diligence-checklist-why-acquiring-firms-need-it/)

A refined technical due diligence process is quick, efficient, and answers the investment questions in easy-to-understand terms with sufficient detail. Target companies are typically analyzed from three perspectives:

Each of these perspectives is analyzed from the following categories. Included below are some sample questions to ask and answer:

While many items found during technology due diligence may not make or break a deal, it is important to understand the risks and opportunities to evaluate a potential investment. The existence of technical risks may affect the ultimate deal conditions or price. The cost of a technical due diligence is insignificant compared to the magnitude of a software company investment and the benefits abound, which leaves us with the question, why wouldn’t an investment firm conduct pre-acquisition technical due diligence? I certainly wouldn’t buy a new home without an inspection.
