Tata AutoComp Systems Interview Questions, Process, and Tips

There are three main types of defects in engineering: design defects, manufacturing defects, and usage defects.

• Design defects occur when there is an issue with the initial design of a product, leading to problems in its functionality or safety. For example, a car with a faulty braking system due to a design flaw.

• Manufacturing defects happen during the production process, resulting in a product that does not meet the in...read more

The 7 wastes refer to inefficiencies in a process that can be eliminated to improve productivity and quality.

• Transportation: Unnecessary movement of materials or products

• Inventory: Excess inventory leading to waste of resources

• Motion: Unnecessary movement of people

• Waiting: Idle time in a process

• Overproduction: Producing more than needed

• Overprocessing: Doing more work than necessary

• Defects: Errors that require rework or

Line balance refers to distributing workload evenly among different stations in a production line to optimize efficiency.

• Line balance ensures that each station in the production line has a similar amount of work to do.

• It helps in preventing bottlenecks and maximizing throughput.

• Line balance can be achieved by adjusting the cycle times at each station or by adding/subtracting workstations.

• An example of line balance is i...read more

To reduce defects and increase productivity, focus on continuous improvement, training, quality control, and efficient processes.

• Implement a quality control system to catch defects early on

• Provide regular training to employees to improve skills and knowledge

• Analyze data to identify root causes of defects and implement corrective actions

• Streamline processes to eliminate waste and improve efficiency

OEE stands for Overall Equipment Effectiveness, a measure of how well a manufacturing process is utilized.

• OEE is calculated by multiplying Availability, Performance, and Quality.

• Factors affecting OEE include equipment downtime, speed loss, and defects in production.

• Improving OEE involves reducing downtime, increasing production speed, and minimizing defects.

• For example, implementing preventive maintenance can reduce eq

Cycle time is the total time taken to complete a process or task from start to finish.

• Cycle time is a key metric in process improvement and efficiency analysis.

• It helps in identifying bottlenecks and areas for improvement in a process.

• For example, in manufacturing, cycle time can refer to the time taken to produce one unit of a product.

• Reducing cycle time can lead to increased productivity and cost savings.

Line balancing is the process of assigning tasks to workstations in a way that evens out the workload and maximizes efficiency.

• Involves distributing work evenly among workstations

• Helps in reducing idle time and bottlenecks

• Improves productivity and efficiency

• Example: In a manufacturing plant, line balancing ensures each workstation has a similar amount of work to do
