Product and technology roadmap

A clear and realistic product and technology roadmap is essential for outlining a company or project’s future direction.

Technical due diligence involves reviewing the roadmap to assess its alignment with business objectives, market trends, technological advancements, and competitive landscape.

An effective roadmap should address key milestones, feature enhancements, platform upgrades, and innovation initiatives.

Intellectual property assessment

Intellectual property (IP) assets, including patents, trademarks, copyrights, and trade secrets, play a critical role in protecting a company’s innovations and competitive advantages.

Further, technical due diligence involves conducting a thorough IP assessment to identify the following:

  • Potential infringement risks
  • Ownership disputes
  • Licensing obligations
  • Gaps in protection

The technical due diligence process

The technical due diligence process typically consists of the following stages:

Initiation and planning

The initiation and planning stage marks the outset of the technical due diligence process, setting the groundwork for subsequent activities.

During this phase, stakeholders convene to delineate the overarching objectives, scope, and establish a realistic timeline for the evaluation.

Collaboratively, they identify key areas of focus, whether it be examining the technology stack, assessing code quality, or evaluating architectural robustness.

With a clear understanding of the goals, criteria, and resource allocation, a comprehensive project plan is meticulously crafted to guide the due diligence endeavor.

Documentation review

Following initiation and planning, the documentation review stage delves into the wealth of technical documentation available. This entails an exhaustive examination of system designs, development methodologies, and infrastructure configurations.

In connection, due diligence support teams gain invaluable insights into the intricacies of the technology landscape. They uncover the nuances of the technology stack and gain visibility into the deployment environment.

Documentation review lays a solid foundation for subsequent assessments, providing a holistic understanding of the target entity’s technical capabilities and limitations.

Interviews and meetings 

Subsequently, interviews and meetings take center stage as technical due diligence teams engage directly with key technical personnel.

They serve as invaluable opportunities to glean firsthand insights into the technology landscape from those closest to it. Through candid discussions, due diligence teams unearth critical nuances that may not be apparent from documentation alone.

These interactions enrich the findings from the documentation review as they help uncover the target entity’s technological strengths and weaknesses.

Code review

In the technical due diligence process, code review stands as a critical stage. Here, a meticulous examination of the source code is conducted to assess its quality, security, and maintainability.

Utilizing both automated tools and manual inspections, experts delve deep into the codebase to initiate the following process:

  • Identify any potential vulnerability issues
  • Ensure adherence to coding standards
  • Uncover hidden issues
  • Evaluate the overall health of the code

Compliance audit

Another integral aspect is the compliance audit. This stage involves a thorough review of the target company’s compliance with relevant regulations, standards, and industry best practices. 

Experts examine adherence to security standards, data privacy regulations, software licensing agreements, and other legal requirements to identify any gaps or non-compliance issues.

By ensuring compliance with regulatory and contractual obligations, stakeholders can mitigate legal and regulatory risks associated with the investment or acquisition.

Moreover, compliance audits assure investors and acquirers, fostering trust and confidence in the target company’s operations and practices.

Follow-up and support

Following the completion of the due diligence process, the follow-up and support stage is essential for ensuring seamless transition and implementation of recommendations.

A detailed report summarizing the findings, recommendations, and action items is prepared and presented to stakeholders. Follow-up discussions may be conducted to address any questions, concerns, or additional information requests from stakeholders.

Moreover, ongoing support may be provided to assist with post-transaction integration, implementation of recommendations, or resolution of identified issues. 

How to prepare for technical due diligence

Preparing for technical due diligence involves several key steps:

  • Ensure that all relevant technical documentation, including architecture diagrams, system designs, and source code repositories, are well-organized and readily accessible.
  • Assess the technology stack, code quality, security posture, and compliance status proactively to identify and address any potential issues or vulnerabilities.
  • Educate key technical personnel about the technical due diligence process, their roles and responsibilities. Explain thoroughly the importance of providing accurate and transparent information during the evaluation.
