accuracy improvement observed between two counts in the case study
analysis framework used together with root cause research
What "critical" means in logistics
In this context, critical means that a stock discrepancy can degrade several functions at once: preparation, replenishment, reporting, customer relationships and financial steering. The case study conducted in a PT. LOGISTIC warehouse shows that inaccuracy is not only a counting problem; it affects the ability to trust the system for operational decision-making.
The dominant human factors
The article identifies data entry errors, failure to follow standard procedures and limited verification practices as dominant sources of divergence. This confirms that discrepancies do not always come from a faulty tool. They also appear when teams work without sufficient validation, with irregular control routines or with instructions applied differently depending on the situation.
System limitations worsen the problem
The authors also note system-side limitations: delayed WMS synchronization, scanner reliability and insufficient validation mechanisms. These points matter because they show that a poorly integrated or poorly controlled WMS can allow inaccuracy to persist. Technology must therefore be designed as an operational control system, not as a simple digital ledger.
Conditions for lasting resolution
The study concludes that lasting improvement requires an integrated approach: human competence, standardized procedures and system optimization. The fact that manual verification remains necessary in the observed case shows that existing controls are still reactive. The target is to bring error detection closer to the moment when the error appears, to prevent the discrepancy from spreading.
Recognizing inventory inaccuracy as a critical problem is the first step. The second is to move beyond one-off fixes: processes, training, scan-based controls, system synchronization and monitoring indicators must be aligned. This coherence is what turns fragile inventory into reliable operational data.
