Implementation
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.
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, ……..

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.
ServiceAn activity that supports the installation, training, maintenance, and repair of a product or structure for the consumer.

Product life cycle
The design phase is the most critical
• Determines the product success or failure in the market place.
• Has a direct impact on product cost, quality, manufacturing, maintenance cost, and disposal cost.
• Approximately 80% of the product cost is fixed at the design stage; it is easier and less costly to change the design in early phases.
Reduction in cost and lead time and improvements in product quality must be sought from all areas of a product-life cycle.
• Design phase• Manufacturing phase• Product usage phase• Disposal phase

Computer Integrated Design and Manufacturing
Companies 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) geometric modeling
Computer-Aided Manufacturing (CAM) Computer Numeric Control (CNC)
Computer-Aided Engineering (CAE) Analysis Finite Element Analysis (FEA)
