A Case Study on Human Behavior, Process Design, and Why Compliance Isn’t Enough
A manufacturing company had invested significant time and resources in developing its Standard Operating Procedures (SOPs). Every critical process—from procurement and inventory management to quality inspections and finance approvals—was documented in detail. Employees received training, manuals were available on the company intranet, and every audit confirmed that the required documentation existed.
Yet operational issues continued to occur.
Purchase requests bypassed approval workflows, inventory movements were recorded late, quality checks were skipped during peak production, and manual workarounds became routine. Management questioned why employees weren’t following procedures despite having clear instructions.
From an internal audit perspective, the problem wasn’t a lack of policies—it was a lack of practicality. The SOPs had been designed around the ideal process, not the reality of day-to-day operations. Employees were expected to complete lengthy approval chains under tight deadlines, navigate multiple systems for a single transaction, and perform repetitive documentation that added little operational value. Over time, informal shortcuts replaced formal processes—not out of negligence, but because they helped employees get their work done.
Rather than asking, “Why didn’t employees follow the SOP?”, I would ask, “Why did the process encourage employees to bypass it?”
The audit would focus on observing how work was actually performed on the shop floor, in warehouses, and across business functions. Interviews with employees would help identify where procedures created delays, duplicated effort, or failed to reflect operational realities. Each deviation would be evaluated to determine whether it represented a control weakness or an opportunity to redesign the process.
The recommendation would not be stricter enforcement or additional documentation. Instead, the organization should simplify approval workflows, eliminate unnecessary process steps, automate repetitive controls through ERP systems where possible, and involve employees in updating SOPs based on practical experience. Effective controls should fit naturally into the way people work rather than forcing people to work around them.
Key Takeaway
An SOP is only valuable if people can realistically follow it. Internal audit should measure not only whether procedures exist, but whether they are practical, efficient, and aligned with human behavior. The strongest control environment is not built on the thickest policy manual—it is built on processes that employees can follow consistently without sacrificing productivity.
