Six Sigma is a data-driven methodology used to improve business processes by reducing defects and variability.

• Six Sigma aims to achieve a process that produces no more than 3.4 defects per million opportunities.

• It involves five phases: Define, Measure, Analyze, Improve, and Control (DMAIC).

• Six Sigma uses statistical tools and techniques to identify and eliminate the root causes of defects.

• It is widely used in industrie...read more

Line balancing is the process of distributing workloads evenly across a production line to optimize efficiency.

• It involves analyzing the tasks required for production

• Assigning tasks to workstations based on their capacity and skill level

• Ensuring that each workstation has a balanced workload

• The goal is to minimize idle time and maximize productivity

• Example: In a car assembly line, line balancing would involve assigning ...read more

POKA yoke is a Japanese term for mistake-proofing or error-proofing.

• It is a technique used to prevent errors or mistakes in a process.

• It involves designing a process or product in a way that makes it impossible or difficult to make mistakes.

• Examples include using color coding, shapes, or sensors to prevent errors.

• POKA yoke can improve quality, reduce waste, and increase efficiency in a process.

Mistral proofing is a process of protecting electronic devices from damage caused by mistral winds.

• Mistral proofing involves designing electronic devices to withstand the strong winds of the Mistral, a cold and dry wind that blows through the Rhone Valley in France.

• This process is important for devices that are used in outdoor environments, such as weather stations, surveillance cameras, and communication equipment.

• Mis...read more

OEE stands for Overall Equipment Effectiveness. It is a measure of how effectively a manufacturing operation is utilized.

• OEE is calculated by multiplying three factors: availability, performance, and quality.

• Availability measures the percentage of time that equipment is available for production.

• Performance measures the speed at which the equipment runs compared to its maximum speed.

• Quality measures the percentage of go...read more

FPY stands for First Pass Yield, which is the percentage of products that pass quality control on the first attempt.

• FPY is a measure of efficiency and quality in manufacturing.

• It is calculated by dividing the number of products that pass quality control on the first attempt by the total number of products produced.

• For example, if 100 products were produced and 90 passed quality control on the first attempt, the FPY wou...read more

4M changes refer to changes in Man, Machine, Material, and Method in a manufacturing process.

• Man refers to changes in the workforce, such as training or hiring new employees.

• Machine refers to changes in equipment or technology used in the manufacturing process.

• Material refers to changes in the raw materials used in the manufacturing process.

• Method refers to changes in the overall process or procedures used in manufactu...read more

The question is nonsensical and has no clear answer.

• There is no logical or mathematical meaning to '14 Q'.

• It is possible that the interviewer is testing the candidate's ability to handle unexpected or confusing questions.

• The best approach is to ask for clarification or to provide a humorous response.

• Example response: '14 Q? Sounds like a secret code for a top-secret mission.'

14Q principal is a quality control principle that emphasizes on prevention of defects rather than detection and correction.

• 14Q principle focuses on preventing defects in the production process

• It emphasizes on quality control rather than quality assurance

• It involves continuous improvement and defect prevention

• Examples include using statistical process control and root cause analysis

5S is a workplace organization method that aims to improve efficiency and productivity by organizing and standardizing the workplace.

• Sort - eliminate unnecessary items

• Set in order - organize remaining items

• Shine - clean and inspect the workplace

• Standardize - establish procedures and standards

• Sustain - maintain and improve the system

• Example: organizing tools in a toolbox

• Example: labeling and arranging files in a cabinet

• ...read more

A sensor is a device that detects and responds to physical input from the environment.

• Sensors convert physical quantities into electrical signals.

• They are used in various industries for monitoring and control purposes.

• Examples of sensors include temperature sensors, pressure sensors, and motion sensors.

PLC stands for Programmable Logic Controller. It is a digital computer used for automation of electromechanical processes.

• PLC is a specialized computer designed to control industrial processes and machinery.

• It uses a programmable memory to store instructions and execute them in a sequential manner.

• PLCs are commonly used in manufacturing, power plants, and other industrial settings.

• They can be programmed to monitor inpu...read more
