An easy way to identify a constraint is that: Constraints have a high rate of failure Constraints resources have a lot of unfinished work Constraints use up the most amount of capital Constraints have the most amount of variation
constraints resources have a lot of unfinished work
In the 5S step to standardize, firms would: Create standard inventive systems for all employees Ensure that production times for all machines are balanced Design products that use more or less the same raw materials Create common color codes for tasks throughout the firm

In the drum-buffer-rope method, material inventory buffers are placed in the warehouse. directly downstream from the drum. directly upstream from the rope. directly upstream from the drum.
directly Upstream from the drum
"Exploit the constraint", refers to: Ensuring that the constraint is always working on a customer requirement Paying the constrained employees only the minimum wages Slowing down non-constraints to work at the pace of constraints Converting a constraint into a non-constraint
ensuring that the constraint is always working on a customer requirement
Software that centralizes business data and allows selective access to employees is known as: Enterprise resource planning (ERP) Manufacturing resource planning (MRP II) Relational database system (RDS) Organization integration planning (OIP)

A key part of total quality management (TQM) is that: The improvement priorities are decided by machine operators The operations excellence department decides the improvement focus Top management stays away from all quality improvement tasks Fast and dramatic changes in quality are aimed at
fashion dramatic changes in quality or aimed at
In the total productive maintenance (TPM) terminology, autonomous maintenance refers to: Maintenance done automatically by robots Designing resources that do not need maintenance Clarifying the work distribution in the maintenance department Getting the operator of the machine to do routine maintenance
getting the operator of the machine to do routine maintenance
A made to stock (MTS) is forced to increase the variety of product if offers to customers. This will most likely lead to: Higher inventories of finished goods Lower quality of products Higher breakdown of machines Higher frustration among machine operators
higher inventories of finished goods
In the 1950s an F1 race car pit stop to refuel and change tires would take around 97 seconds. As of now, the same process takes less than 3 seconds. The F1 companies have: Eliminated external setup activities and converted non-value added to internal setup Eliminated internal setup activities and converted non-value added to external setup Eliminated non-value-added times and converted external to internal setup Eliminated non-value-added times and converted internal to external setup
illuminated non-value-added times and converted internal to external setup
In process management, the material or information provided by a supplier are known as: Inputs Resources Sources Feedstock
inputs
Kanban creates a uniform flow by: Improving employee motivation Ensuring high machine availability Forcing employees to work at rated speed Limiting the work in process inventories
limiting the work-in-process inventories
A major difference of pull system from push system is that pull systems have: Higher inventory, lower lead time, higher customer satisfaction Lower inventory, higher lead time, higher customer satisfaction Lower inventory, lower lead time, lower customer satisfaction Lower inventory, lower lead time, higher customer satisfaction

In firms with strong processes, the skills become easily transferable. Here 'transferable' refers to: New employees can be taught those skills easily The task completion time becomes similar in all facilities of the firm Anyone can become capable of doing any task Human tasks can be easily transferred to computers
