Technical Due Diligence

Assessing another company's technology, as in an acquisition.

Technical due diligence is an assessment of a company’s technology, systems, and engineering practices to inform a business decision, such as an acquisition, investment, or partnership. It aims to understand material risks and opportunities, not to produce a complete code audit in a short period.

A review may examine architecture, security, reliability, data practices, team ownership, vendor dependencies, and the ability to change or operate the product. Ask for evidence and distinguish observed facts from assumptions. For example, a service diagram may show a single database, but operational records and recovery tests reveal more about resilience than the diagram alone.

Time and access are limited, and the company being assessed may have confidentiality constraints. Prioritize risks that could change the decision or require substantial remediation. Avoid treating a code-style preference as a business-critical finding, and be clear where evidence was unavailable.

Backend diligence looks at architecture, operability, and team ownership. Frontend diligence checks experience quality and delivery practice. Data diligence examines source reliability and governance. Focus questions on what would change the business decision. Note where access was limited, and separate confirmed findings from inferences that need follow-up. State confidence plainly where evidence was thin. Separate facts from follow-up questions in the report.

Backend, frontend, and data specialists should assess the systems they understand and explain impact in plain terms. Preserve sensitive information and follow the agreed process. Estimates of remediation effort are uncertain; state the assumptions and confidence. See risk management, security review, and technical strategy.
