OVERALL EQUIPMENT EFFECTIVENESS EXAM QUESTIONS AND ACCURATE
ANSWERS 2024/2025 | VERIFIED
5 Why Analysis - ✔️✔️A simple process originally created by Sakichi Toyoda at the Toyota Motor
Company for identifying the root cause behind a particular problem. Start with a problem definition, and
keep asking "why" until the root cause is uncovered.
5S - ✔️✔️A Lean Manufacturing process that creates an organized work area. 5S has five steps: Sort
(eliminate unneeded items), Set (organize remaining items), Shine (clean and inspect the work area),
Standardize (document standards for the area), Sustain (apply and audit the standards).
Actual Cycle Time - ✔️✔️The actual time to produce one part. In OEE, calculated as Run Time divided
by Total Count. Used in calculating OEE Performance. A variation of the calculation uses Actual Run Rate
instead.
Actual Run Rate - ✔️✔️The actual rate of production, when it is running. In OEE, calculated as Total
Count divided by Run Time. Used in calculating OEE Performance. A variation of the calculation uses
Actual Cycle Time instead.
All Time - ✔️✔️24 hours in a day, 7 days in a week. All time refers to every minute of every day.
Andon - ✔️✔️Indicator above production line to signal production conditions. Often uses
green/yellow/red colors to indicate status.
Autonomous Maintenance - ✔️✔️A process from TPM (Total Productive Maintenance) for improving
machine OEE by engaging operators to complete routine maintenance, inspection, and lubrication
activities.
Availability Loss - ✔️✔️One of the three OEE Losses. Availability takes into account Equipment Failures
and Setup and Adjustments. An Availability score of 100% means that the process is always running
during Planned Production Time.
Best Practice - ✔️✔️Methods that are considered "state of the art" by the most respected in an
industry. Successful companies use different methods than unsuccessful companies.
, Brainstorming - ✔️✔️A process for creating an expanded world of ideas and possibilities. Brian
storming is a divergent problem solving process that is intended to create a broad range of ideas that can
then be refined by a root cause process.
Breakdowns - ✔️✔️A type of Unplanned Stop where time is lost due to Equipment Failure (one of the
Six Big Losses). Breakdowns are a type of Unplanned Stop and affect OEE Availability.
Breaks - ✔️✔️Unproductive time where the process is scheduled not to run because the crew is
scheduled to be away from the line. Breaks are typically excluded from OEE calculations.
Capacity - ✔️✔️The maximum amount of production available if equipment is fully productive (running
at 100% OEE), for All Time (24/7).
Changeover - ✔️✔️The manufacturing process is scheduled for production and is not running because
of a planned Setup, Make Ready, or Adjustment event. Changeovers are a type of Planned Stop and
affect OEE Availability.
Constraint - ✔️✔️The step of the manufacturing process that acts as a bottleneck to the throughput of
the entire process. OEE should always be measured at the constraint as it is the slowest step in the
process.
Countermeasures - ✔️✔️An action to counter or mitigate a manufacturing loss. A manufacturing loss
may benefit from multiple countermeasures including immediate actions to prevent the loss from
getting worse, short term fixes and long term root cause fixes.
Cycle Time - ✔️✔️The time to produce one part. Inverse of Run Rate.
Cycle Time Analysis - ✔️✔️Tool used to better understand issues that affect Performance. Important to
automate logging of Cycle Times for later analysis.
Defect - ✔️✔️Any part that is not right first time. Defects may be reworked, or scrapped. All defects are
a loss to OEE Quality.
Design Cycle Time - ✔️✔️See Ideal Cycle Time.
