Question 1

When a mini excavator consistently undercuts the specified trench depth by 2 inches, the FIRST corrective action should be:

Accepted Answer

Re-calibrate the depth indicator or verify bucket tooth wear

Answer

Systematic depth errors typically point to a worn bucket, misread indicator, or improperly set depth stop, so calibration and inspection of wear items should be the first corrective step.

Question 2

Which document is most useful for tracking recurring mini excavator defects over multiple shifts?

Accepted Answer

Defect trend log or recurring-issue register

Answer

A defect trend log consolidates issues across shifts, making it possible to identify patterns and prioritize corrective actions.

Question 3

A Kaizen event focused on mini excavator operations is best described as:

Accepted Answer

A short, intensive team effort to identify and eliminate waste in a specific workflow

Answer

Kaizen events are time-boxed, team-driven improvement workshops aimed at rapidly reducing waste and improving a targeted process.

Question 4

An operator notices that spoil piles are consistently placed too close to the excavation edge. Which process improvement tool would best map the steps leading to this problem?

Accepted Answer

Process flow diagram

Answer

A process flow diagram visually maps each step in a workflow, making it easier to pinpoint where the spoil-placement decision is made incorrectly.

Question 5

During a quality audit of excavation work, inspectors find that 70% of defects stem from just 3 out of 15 identified causes. This principle is best represented by:

Accepted Answer

The 80/20 Pareto principle

Answer

The Pareto principle states that roughly 80% of effects come from 20% of causes, making it a useful prioritization tool for defect reduction.
