When Persistent Defects, Yield Losses, or Process Variability Require Real Technical Investigation
Some manufacturing improvement work looks routine on the surface but may qualify for SR&ED. When recurring defects or yield issues cannot be resolved through standard methods, the work often becomes more technical than businesses expect.
What Separates Routine Improvement from SR&ED
Routine inspections, standard troubleshooting, and known process adjustments usually do not qualify. The line starts to shift when the cause of the problem is unknown and the team must test different approaches to determine what will actually work.
What This Looks Like in Practice
Weld Quality Variability
Consider a fabricator facing inconsistent weld strength despite following approved parameters and standard procedures. The problem persists, but standard troubleshooting does not identify the cause.
To isolate the issue, the company tests different pre-treatment methods, cooling rates, humidity conditions, and parameter combinations. That investigation reveals an unexpected interaction between humidity and surface chemistry, leading to a revised process supported by evidence rather than assumption.

What Usually Does Not Qualify
- Routine inspections and quality checks
- Standard statistical process control
- Following vendor troubleshooting steps
- Applying known industry solutions
- Regular maintenance or calibration work
Quick test: if the team already knew the solution and only needed to implement it, the work is unlikely to qualify. If it had to investigate, test, and learn its way to the answer, it may be worth a closer look.
Why This Matters
Many manufacturers overlook claim opportunities because technically complex improvement work gets dismissed as routine too early. In reality, some of the strongest claims come from persistent production-floor problems that required structured experimentation to solve.
If your business has been working through persistent defects, unexplained variability, or yield challenges that standard methods could not resolve, it may be worth assessing whether that work supports a defensible SR&ED claim.
