Start with the business outcome
A technical review should begin with the outcome the software must support. If the business goal is not clear, the architecture, timeline, and budget cannot be judged fairly. Before evaluating code or proposals, confirm the users, workflows, integrations, data, security expectations, and operational responsibilities.
- What business process will the system improve or replace?
- Who owns product decisions, approvals, and change requests?
- What data will be created, imported, stored, exported, or deleted?
- Which systems must integrate with the application?
- What happens if the application is unavailable for a day?
Review the development plan before the code
Many problems show up before a developer writes a line of code. Weak proposals often skip user roles, acceptance criteria, environments, deployment approach, reporting, maintenance, and testing. A strong plan explains how the team will turn requirements into working software and how the client will verify progress.
Ask for proof, not just confidence
A vendor may be skilled and still be the wrong fit for the project. Ask to see related work, repository structure, deployment examples, documentation samples, issue tracking, and a clear explanation of how decisions are made. The goal is not to micromanage developers. The goal is to make progress measurable.
A good technical review turns confidence into evidence.
Check ownership and handoff risk
Business owners should understand who controls the domain, hosting account, code repository, databases, environment variables, third-party services, and deployment pipeline. If a vendor disappears, the company should still be able to access the assets it paid for.
Evaluate security and operations early
Security should not wait until launch week. Review authentication, authorization, logging, backup strategy, data retention, secrets management, role-based access, and incident response assumptions while the project is still flexible. These items affect architecture and cost.
Common Questions
When should a company request technical due diligence?
Before hiring a development team, buying an existing software product, rescuing a delayed project, or funding a major rebuild.
Does due diligence require access to source code?
Source code is helpful, but early reviews can still evaluate requirements, architecture, vendor proposals, security assumptions, deployment plans, and ownership risk.
