Implementation
ServiceAn activity that supports the installation, training, maintenance, and repair of a product or structure for the consumer.
FinanceAnalyzes the feasibility of producing a product, relative to capital requirements and return on investment (management of cash flow).
MarketingAnticipates customer needs and directs the flow of goods from the producer to the consumer – much more than just selling and advertising. Satisfy the customer at a profit.

Implementation
DocumentationDocumentation is a process used to formally record and communicate the final design solution. 3D models are used as inputs to the documentation stage to create engineering drawings, technical illustration, animation, and patent drawings. Documentation thus becomes a concurrent activity throughout the design process, instead of something that occurs only at the end.
ProductionProduction is a process used to transform raw materials into finish products, using labor, equipment, capital, and facilities. It requires engineering drawings, technical specifications, bill of materials, ……..

Computer Integrated Design and ManufacturingComputer Integrated Design and ManufacturingCompanies must deliver products to customers at the minimum possible cost, the best possible quality, and the minimum lead time starting from the product conception stage to final delivery, service and disposal.
The core of computer technology includes:
Computer-Aided Design (CAD) Design using geometric modeling,
Shading and Rendering
Computer-Aided Manufacturing (CAM) Computer Numeric Control (CNC),
Die and Mold design, Welding, Sheet metal
Computer-Aided Engineering (CAE) AnalysisFinite Element Analysis (FEA),
Optimization, Evaluation
