Due diligence is a software risk-review process that verifies a system's security, quality, ownership, and operational readiness before adoption or release. In technology, it means checking evidence rather than relying on vendor claims, assumptions, or a successful demo. The depth of review should match the application's data sensitivity, user impact, and integration risk.
Due Diligence
What Is Due Diligence in Software Engineering?
Due diligence is a software risk review that verifies security, quality, ownership, and operational readiness before adoption or release. It checks evidence rather than relying on demos, documentation, or vendor claims.
Technical due diligence focuses on how software is built, connected, secured, tested, and maintained.
What Does It Mean to Do Your Due Diligence?
Doing due diligence means gathering verifiable evidence before a technical decision. Teams test key claims, document findings, assign risk owners, and set conditions for purchase, integration, or deployment.
For example, a security claim should prompt questions about access controls, vulnerability testing, incident response, and updates.
Software Due Diligence Checklist
A repeatable workflow focuses reviews on the most important risks.
- Define the decision, scope, and risk level.
- Map data flows, users, APIs, and integrations.
- Review security and privacy controls.
- Assess architecture, code, and dependencies.
- Validate reliability, support, backups, and recovery.
- Test critical workflows.
- Record findings, owners, deadlines, and release conditions.
Types of Technical Due Diligence
Projects may need several review types.
| Type | What it checks | When needed |
|---|---|---|
| Security | Access, vulnerabilities, encryption | Before handling customer data |
| Privacy | Data use, retention, permissions | Before collecting personal information |
| Architecture | Design, scaling, integrations | Before a major rollout |
| Code quality | Tests, maintainability, ownership | Before inheriting a codebase |
| Open-source licensing | Component licenses and obligations | Before commercial release |
| AI model and data | Inputs, outputs, safeguards, evaluation | Before adding AI features |
| Operational reliability | Monitoring, backups, rollback | Before production deployment |
| Vendor | Support, security practices, lock-in | Before adopting a third-party service |
Benefits of Due Diligence for Software Projects
Evidence-based review improves decisions before problems reach users.
- Finds security gaps and risky permissions earlier.
- Exposes integration and maintenance costs.
- Identifies unsupported or outdated dependencies.
- Clarifies code ownership and licensing restrictions.
- Tests recovery and rollback plans.
- Replaces vague claims with documented proof.
Practical Limits of Technical Due Diligence
A review reduces uncertainty but cannot guarantee defect-free software.
- Vendor evidence may be incomplete or outdated.
- Dependencies and threats can change after review.
- Checklists can create false confidence without testing.
- Time limits require prioritizing high-impact risks.
- Findings need follow-through, not just documentation.
A Practical Example: Reviewing an AI-Powered App
For a customer-support app that sends messages to an AI service, due diligence maps customer-data flows, verifies permissions and retention settings, tests prompt-injection defenses, and confirms human review of sensitive responses. Teams should also test alerts and prove they can disable the AI feature or roll back safely. This work supports thoughtful app design and development.
Due Diligence When Building With Emergent
Teams using Emergent can apply due diligence by defining requirements, reviewing integrations and generated code, testing critical user flows, and validating deployment settings before shipping. An AI web app builder can speed delivery, but teams remain responsible for data handling, access, and production reliability.
