Iterative design is a design methodology based on a cyclic process of prototyping, testing, analyzing, and refining a product or process. Based on the results of testing the most recent iteration, changes and refinements are made. This process is intended to ultimately improve the quality and functionality of a design by repeatedly cycling through these steps.

'Use by' dates are related to food safety. They are used on foods that are highly perishable from a microbiological perspective and could pose an immediate danger to human health after a short period. In contrast, 'best before' or 'best if used by' dates relate to food quality, indicating when the product will be at its peak flavor, texture, and nutritional value.

A Trilogia de Juran, desenvolvida pelo Dr. Joseph M. Juran, é uma abordagem fundamental de gestão da qualidade composta por três processos interconectados: Planejamento da Qualidade, Controle da Qualidade e Melhoria da Qualidade. Essa estrutura fornece uma maneira estruturada para as organizações gerenciarem a qualidade. Ela enfatiza que a qualidade não acontece por acaso; deve ser planejada e gerenciada sistematicamente.

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.

Fused Deposition Modeling (FDM), sometimes named Fused Filament Fabrication (FFF), a material extrusion technique, builds objects by selectively depositing molten material in a pre-determined path layer-by-layer. A thermoplastic filament is unwound from a coil and fed through a heated extruder nozzle. The nozzle melts the filament and deposits it onto a build platform, where it cools and solidifies, fusing with the layer below.

FMECA is an extension of FMEA that includes a criticality analysis, which charts the probability of failure modes against the severity of their consequences. This allows for a quantitative ranking of failure modes based on the combined influence of their severity and probability. The result highlights single points of failure and helps prioritize corrective actions based on a more rigorous risk level.

Indoor concentrations of VOCs from sources like building materials, furniture, and cleaning agents often exceed outdoor levels. Total Volatile Organic Compounds (TVOC) is a metric representing the summed concentration of multiple individual VOCs in the air. It is widely used as a general screening tool for assessing indoor air quality (IAQ), though it doesn't distinguish between high and low toxicity compounds.

Surface micromachining builds MEMS devices by depositing and patterning thin films on a substrate. It involves a sequence of depositing a sacrificial layer (like silicon dioxide), patterning it, depositing a structural layer (like polysilicon), and finally removing the sacrificial layer to release the mechanical structure. This process allows for the creation of complex, free-standing microstructures directly on the wafer surface.

A estereolitografia é um processo de fabricação aditiva por fotopolimerização em cuba. Utiliza um laser ultravioleta (UV) para curar e solidificar seletivamente uma resina fotopolimérica líquida. Uma plataforma de construção é submersa na resina, e o laser traça uma seção transversal do objeto na superfície. A plataforma então desce a espessura de uma camada, permitindo que uma nova camada de resina seja curada por cima.

Seis Sigma é uma metodologia disciplinada e baseada em dados para eliminar defeitos em qualquer processo – da manufatura às transações e do produto ao serviço. A representação estatística do Seis Sigma descreve um processo onde 99,99966% de todas as oportunidades de produzir alguma característica de uma peça têm probabilidade estatística de estarem livres de defeitos (3,4 defeitos por milhão de oportunidades).

A Sinterização Seletiva a Laser (SLS) é um processo de fabricação aditiva por fusão em leito de pó. Utiliza um laser de alta potência para sinterizar, ou fundir, seletivamente partículas de um pó polimérico. Um rolo espalha uma fina camada de pó sobre a área de construção, o laser escaneia uma seção transversal da peça e a plataforma de construção desce. Esse processo se repete, construindo o objeto camada por camada.

ISO 9001 is the world's most recognized standard for Quality Management Systems (QMS). It provides a framework and a set of principles that ensure a common-sense approach to the management of an organization to consistently satisfy customers and other stakeholders. It is based on seven quality management principles, including a strong customer focus and a process-based approach.

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).
