Dr Lal PathLabs Interview Questions and Answers
Q1. What is RPN? How its calculated.
RPN stands for Risk Priority Number. It is a numerical value used in risk assessment to prioritize potential failures.
RPN is calculated by multiplying three factors: Severity, Occurrence, and Detection.
Severity represents the potential impact of a failure on the system or process.
Occurrence represents the likelihood of the failure occurring.
Detection represents the ability to detect the failure before it causes harm.
The formula to calculate RPN is: RPN = Severity × Occurrence...read more
Q2. What is Bill of Materials ?
Bill of Materials is a comprehensive list of raw materials, components, and assemblies required to manufacture a product.
It includes information about the quantity, part number, and description of each item.
It helps in planning and managing the production process.
It is used in inventory management and cost estimation.
Example: A bill of materials for a bicycle would include the frame, wheels, pedals, brakes, etc.
Example: A bill of materials for a computer would include the mot...read more
Q3. Explain 5S and Lean Manufacturing
5S is a methodology for organizing and maintaining a clean, efficient, and safe work environment. Lean Manufacturing is a systematic approach to eliminating waste and improving efficiency.
5S focuses on five principles: Sort, Set in Order, Shine, Standardize, and Sustain.
Sort involves removing unnecessary items from the workplace.
Set in Order involves organizing and arranging necessary items in a logical and efficient manner.
Shine involves cleaning and maintaining the workplac...read more
Q4. Poke Yoke explain.
Poka Yoke is a technique used in manufacturing to prevent errors or mistakes from occurring.
Poka Yoke is a Japanese term that translates to 'mistake-proofing' or 'error-proofing'.
It involves designing processes or systems in a way that makes it impossible or difficult for errors to occur.
Poka Yoke techniques can include using sensors, guides, or visual cues to prevent or detect errors.
Examples of Poka Yoke include using different-shaped connectors to prevent incorrect connect...read more
Q5. GD&T Explain Briefly.
GD&T stands for Geometric Dimensioning and Tolerancing. It is a system used to define and communicate engineering tolerances.
GD&T is a symbolic language used to specify the dimensions, form, orientation, and location of features on a part.
It ensures that parts are manufactured within acceptable limits and that they fit and function properly.
GD&T uses symbols, such as concentricity, perpendicularity, and position, to convey specific requirements.
It provides a clear and standar...read more
