Product Quality: Dimensions and Testing

• Quality is the degree of excellence or superiority of something, meeting expectations and standards.
• A high-quality product is durable, reliable, and performs well, whereas a low-quality product may break easily or not work as expected.

Dimensions of Product Quality

• Performance consists of the primary operating characteristics of a product.
• Features are added characteristics that boost the attraction of the product or service to the user.
• Reliability refers to the likelihood that a product will not fail within a specific time period.
• Failure rate measures the frequency with which a component fails, expressed in failures per unit of time.
• Conformance indicates to what extent a product design and operating characteristics meet established standards.
• Durability assesses how much use a person gets from a product before replacement is needed instead of repair.

Types of Durability Testing:

• Vibration testing assesses a product's durability by exposing it to vibrations.
• Shock testing replicates events to determine if a structure can withstand sudden applied forces.
• Climate testing evaluates how materials deteriorate over time due to temperature extremes.
• Serviceability involves customer ease of obtaining repair service, like access to service centers or self-service.
• Aesthetics covers how a product looks, feels, sounds, tastes, or smells, reflecting personal judgment and individual preferences.
• Perceived quality is an individual's subjective appraisal of a product's attributes, used for comparing brands.

Dimensions of Service Quality

• Service is described as an experience felt by the customer.
• Tangibles refer to the environment in which the service is rendered to customers.
• Assurance is defined as employees' knowledge, courtesy, and ability to inspire trust and confidence.
• Responsiveness is the willingness to help customers and provide prompt service, emphasizing attentiveness to customer requests.
• Service Reliability is the ability to perform the promised service dependably and accurately.
• Empathy refers to the caring attitude that an organization provides toward customers.

Global Competitiveness

• Global competitiveness is a country's ability to create and sustain an advantage in the global marketplace.
• Productivity measures how efficiently a country uses its resources.
• Innovation is the ability to develop new ideas and technology.
• Infrastructure refers to the quality of a country's transportation, communication, and energy systems.
• Education and skills reflect the quality of a country's workforce.
• Business Environment describes the ease of doing business in a country.
• Global Policies are those that support economic growth and competitiveness.

Quality and Global Competitiveness

• Companies now compete globally and must produce world-class quality products to compete.
• The focus is on achieving "best cost" and "best quality."
• Quality and competitiveness are closely linked; high-quality products or services help a company stand out, attract customers, increase sales/market share and boost competitiveness.
• This leads to job security, better pay, and growth opportunities.
• Success boosts employee satisfaction and financial benefits.
• Poor quality includes wasted materials, rework, customer complaints, and lost sales, negatively effecting competitiveness.

Impact of Competitiveness on Quality of Life

• Competitiveness directly impacts citizens' quality of life.
• Economic Growth is impacted because a competitive country attracts investments/businesses, creating more jobs and opportunities.
• Innovation and Technology is effected through a competitive environment, which encourages businesses to innovate and adopt new technologies.
• Government Investment enables a state to invest in education, infrastructure, and healthcare, which benefits citizens directly via services and opportunities.
• Social Well-being is prioritized in a competitive country, ensuring access to education, healthcare, and social safety nets.

Factors Inhibiting Competitiveness

• High costs, like excessive healthcare, expensive litigation, and regulations, can make businesses less competitive.
• A short-term focus, where companies prioritize short-term profits over long-term investments, can cause them to fall behind.
• Lack of government support in infrastructure, education, and R&D can hinder global competitiveness.
• Corruption, bribery, nepotism, and lack of transparency can discourage foreign investment.
• Lack of parental support for education and low expectations can negatively impact children's academic achievement.
• Limited access to quality childcare can affect parents' ability to work and contribute to the economy.
• Social and cultural barriers like discrimination, prejudice, and lack of opportunities limit potential and hinder competitiveness.
• Inadequate education systems can mean graduates lack the skills and knowledge needed for a competitive global economy.
• Limited access to higher education restricts the availability of high costs, limited scholarships, and insufficient university capacity.
• Lack of focus on STEM fields can lead to a shortage of skilled workers.
