Diagnostic review means systematically finding problems, inconsistencies, and risks in a contract before you start making changes. It’s like running tests before treating a patient – you need to understand what’s wrong before you can fix it.

Why diagnostics matter

Jumping straight to redlines without proper diagnosis leads to:
  • Missing critical issues hidden in unexpected sections
  • Making changes that conflict with other provisions
  • Focusing on minor issues while major problems go unnoticed
  • Creating new problems while trying to fix others
A good diagnostic review takes 5 minutes but saves hours of back-and-forth.

Core diagnostic techniques

The completeness check

Look for what’s missing, not just what’s wrong:
What’s absent often matters more than what’s present.

The consistency check

Find conflicts within the document:

The definition audit

Verify all key terms are properly handled:

The cross-reference check

Ensure all internal references work:

Advanced diagnostic patterns

The ambiguity scan

Find language that could be interpreted multiple ways:

The risk heat map

Categorize issues by severity and likelihood:

The enforceability review

Identify provisions that might not hold up:

The operational feasibility check

Find terms that legal can accept but operations can’t implement:

For low-risk, routine documents:

The standard review (15 minutes)

Using AI for diagnostics

The right prompts for diagnostics

Building diagnostic chains

Avoiding diagnostic blind spots

Don’t rely solely on AI. Always manually check:
  • Payment terms and calculations
  • Key dates and deadlines
  • Specific numbers and percentages
  • Technical requirements in your domain

Common diagnostic mistakes

Surface-level review

Only looking at obviously important sections while missing buried problems.

Assuming completeness

Thinking that if the big issues are covered, details don’t matter.

Ignoring interactions

Reviewing provisions in isolation without considering how they work together.

Skipping the diagnostic

Going straight to redlines because you “know what’s wrong.”

Red flags that need immediate attention

During diagnostics, these issues should trigger immediate deeper review:
  • Uncapped or unlimited liability anywhere
  • One-sided indemnification
  • No termination rights for your side
  • Automatic renewals with short notice windows
  • Audit rights without restrictions
  • Assignment rights allowing change of control
  • IP ownership transfers
  • Non-standard governing law or venue

Diagnostic documentation

Keep track of what you find:
This becomes your roadmap for negotiations.

The key insight

Diagnostic review isn’t about finding every possible issue – it’s about systematically identifying what matters for this specific deal. A good diagnostic gives you a clear picture of the document’s problems before you start proposing solutions. Think of it as creating a map of the minefield before you start walking through it.

Remember

The best negotiators don’t start with solutions; they start with understanding. Thorough diagnostics prevent you from fixing the wrong problems or missing the real issues. Spend time upfront to understand what you’re dealing with, and the rest of the review becomes much more focused and effective.
