Volvo Production System
This Volvo philosophy focuses on eliminating waste and creating value for the customer.
Engineers use this document to define the correct sequence of assembly tasks.
What is a Standard Work Instruction?
The first "Q" in Volvo's QDCI performance model stands for this.
What is Quality?
Excess inventory is one of the traditional "Seven Wastes" known by this Japanese term.
What is Muda?
This component transfers engine torque to the drive axle while allowing relative motion between the cab and chassis.
What is a driveshaft?
In Volvo assembly operations, takt time is primarily determined by this factor.
What is customer demand?
This engineered device ensures a component can only be installed correctly.
What is Poka-Yoke (Error Proofing)?
This quality tool repeatedly asks "Why?" to identify the true root cause of a problem.
What is the 5 Why Analysis?
The 5S step that ensures items are returned to designated locations is called this.
What is Set in Order?
The purpose of torque on critical fasteners is to create this mechanical condition.
What is clamp load?
This metric compares actual production output against planned production output.
What is efficiency?
In assembly engineering, reducing reaches, walks, and twisting improves this ergonomic metric.
What is operator safety and ergonomics?
A process produces 1000 parts with 10 defects. The defect rate is this percentage.
What is 1%?
Producing more trucks than customer demand requires creates this waste.
What is Overproduction?
Torque is the product of force and this distance.
What is the moment arm (lever arm)?
When a workstation consistently limits the output of an entire assembly line, it becomes this.
What is a bottleneck?
A fixture that positions parts consistently improves assembly repeatability by controlling this.
What is variation?
This document visually identifies potential failure modes and mitigation actions before production issues occur.
What is an FMEA?
A Kanban system is primarily used to control this.
What is material replenishment and inventory flow?
Engineers use this concept to ensure a truck component can withstand expected operating loads.
What is Factor of Safety?
A production line runs 450 minutes per day with a customer demand of 180 trucks. Calculate the takt time.
What is 2.5 minutes (150 seconds)?
An operator installs four bolts in 40 seconds. Engineering requires production to increase by 20% without increasing labor. What must the new cycle time be?
What is approximately 33 seconds?
A torque tool occasionally misses a tightening cycle. What type of control should be added to immediately detect the issue?
What is error proofing with torque verification or tool interlock?
Name five of the seven classic wastes.
What are Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing, and Defects?
A bracket experiences a load of 2,000 N and has a design factor of safety of 2. The bracket must be capable of handling at least this load before failure.
What is 4,000 N?
