7QC tools are a set of quality control tools used to identify and solve quality problems in manufacturing processes.

• 7QC tools include Pareto chart, cause-and-effect diagram, control chart, histogram, scatter diagram, flowchart, and check sheet.

• They help in identifying and analyzing quality problems, determining root causes, and implementing corrective actions.

• They are used to improve product quality, reduce defects, and increase customer satisfaction.

• For example, a Pareto cha...read more

Cycle time is the total time it takes to complete a process, while tact time is the time it takes to produce one unit.

• Cycle time includes all the time spent on a process, including wait time and processing time.

• Tact time is the rate at which a product must be produced to meet customer demand.

• For example, if a process takes 10 minutes to complete and the customer demand is 100 units per hour, the tact time would be 0.6 minutes per unit.

• Cycle time can be used to identify bottle...read more

PPAP and APQP are quality management systems used in manufacturing.

• PPAP stands for Production Part Approval Process and is used to ensure that manufactured parts meet customer requirements.

• APQP stands for Advanced Product Quality Planning and is used to plan and manage the design and development of new products.

• Both systems are commonly used in the automotive industry but can be applied to other manufacturing industries as well.

• PPAP involves a series of steps including design...read more

OEE can be calculated by multiplying Availability, Performance, and Quality percentages.

• Calculate Availability by dividing Operating Time by Planned Production Time.

• Calculate Performance by dividing Actual Production by Maximum Production.

• Calculate Quality by dividing Good Units by Total Units Produced.

• Multiply Availability, Performance, and Quality percentages to get OEE.

Production is the process of creating goods or services, while quality refers to the standard of those goods or services.

• Production involves the manufacturing or creation of goods or services.

• Quality refers to the standard or level of excellence of those goods or services.

• Production and quality are closely linked as the goal is to produce high-quality products efficiently.

• Examples: In a manufacturing plant, production involves assembling products, while quality control ensure...read more

Line balancing is the process of evenly distributing workload among workstations in a production line to optimize efficiency.

• Line balancing aims to minimize idle time and maximize productivity

• It involves assigning tasks to workstations based on their processing times

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

Assembly balancing is the process of optimizing the work distribution among different workstations to improve efficiency and productivity.

• Assembly balancing involves assigning tasks to different workstations in a way that minimizes idle time and maximizes throughput.

• It helps in achieving a smooth flow of work and prevents bottlenecks in the production process.

• Factors considered in assembly balancing include task time, workstation capacity, and worker skill levels.

• Example: In ...read more

Pareto is a principle that states 80% of effects come from 20% of causes.

• Also known as the 80/20 rule

• Used in business to identify the most important factors

• Can be applied to various fields such as economics, engineering, and social sciences

• Example: 80% of a company's profits come from 20% of its customers
