ISO 9001 Quality Management System Standard

To address the inability of different CAD systems to share data, neutral file formats were created. The Initial Graphics Exchange Specification (IGES), developed in the late 1970s, was an early attempt. It was later superseded by the more robust and comprehensive STEP (Standard for the Exchange of Product model data, ISO 10303), which can represent full 3D models, assembly structure, and metadata.

Concurrent engineering, also known as simultaneous engineering, is a design philosophy that emphasizes the parallelization of tasks. Instead of a sequential process where design is completed before manufacturing is considered, it involves a team-based approach where designers, manufacturing engineers, and other stakeholders work together from the outset. This overlap significantly reduces product development time and improves design quality.

The Juran Trilogy, developed by Dr. Joseph M. Juran, is a foundational quality management approach consisting of three interconnected processes: Quality Planning, Quality Control, and Quality Improvement. This framework provides a structured way for organizations to manage for quality. It emphasizes that quality does not happen by accident; it must be planned and managed systematically.

Life-Cycle Assessment (LCA) is a systematic methodology for evaluating the environmental impacts associated with all stages of a product's life. This "cradle-to-grave" or "cradle-to-cradle" analysis considers raw material extraction, processing, manufacturing, distribution, use, repair, maintenance, and final disposal or recycling. It quantifies inputs like energy and raw materials and outputs like emissions to air, water, and soil.

Solid-state batteries replace the liquid or polymer gel electrolyte of conventional batteries with a solid, ion-conducting material, such as a ceramic or solid polymer. This design aims to improve safety by eliminating flammable liquid electrolytes and to increase energy density and lifespan by enabling the use of high-capacity anodes, particularly pure lithium metal.

Viral marketing describes any marketing strategy that encourages individuals to pass on a marketing message to others, creating the potential for exponential growth in the message's exposure and influence. Like viruses, such strategies take advantage of rapid multiplication to explode the message from person to person. It is a form of amplified word-of-mouth, often facilitated by the internet.

Total Quality Management (TQM) is a management philosophy where all members of an organization participate in improving processes, products, services, and the culture in which they work. It aims for long-term success through customer satisfaction. TQM integrates quality-discipline into the culture and activities of a company, moving beyond simple product inspection to a holistic, organization-wide approach.

Successful Takt time implementation requires a highly stable production environment. Common challenges include managing machine downtime, ensuring consistent quality to avoid rework, and balancing lines that produce multiple products with different work contents (mixed-model lines). Without addressing these sources of variability, a Takt-driven system can be brittle and fail to meet demand consistently.

Six Sigma is a disciplined, data-driven methodology for eliminating defects in any process – from manufacturing to transactional and from product to service. The statistical representation of Six Sigma describes a process where 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects (3.4 defects per million opportunities).

Parametric modeling is a CAD paradigm where designs are defined by parameters and constraints rather than just geometric shapes. Dimensions and relationships between features (e.g., parallelism, tangency) are stored as parameters. Modifying a parameter value automatically updates the entire model, maintaining the defined constraints. This approach facilitates design iteration, automation, and the creation of design families.

B2B business models are often categorized as either vertical or horizontal. A vertical B2B model focuses on a single industry or 'vertical,' providing specialized products and services tailored to that sector's unique needs (e.g., software for dentists). In contrast, a horizontal B2B model offers a product or service that is applicable across multiple industries (e.g., accounting software or office supplies).

LCA system boundaries define which life cycle stages are included in the assessment. A "cradle-to-grave" analysis covers the entire product life, from raw material extraction through manufacturing, use, and final disposal. In contrast, a "cradle-to-gate" assessment is a partial LCA that ends when the product leaves the factory gate, excluding the use and disposal phases.

The three pillars of sustainability, also known as the triple bottom line, is a framework that posits true sustainability requires balancing three main dimensions: environmental, social, and economic. Environmental sustainability focuses on preserving natural resources and ecosystems. Social sustainability addresses equity, community well-being, and human rights. Economic sustainability ensures long-term financial viability without compromising the other two pillars.

The functional unit is a critical concept in LCA that defines the quantified performance of a product system for use as a reference unit. It ensures that comparisons between different systems are made on a fair and equivalent basis. For example, when comparing paint, the functional unit might be 'to protect 1 square meter of wall for 10 years'.
