Phase I Product planning Establish cross-functional product realization team Define basic global market demands Define attractiveness demands of market segment CIP via product architecture Distributed realization via modularity Determine type of design to be used (original, adaptive or variant) Modify the design method according to the specific design type Schedule the design project (Use 7M&P etc.) Plan design team structure-decide if experts from other fields are required (consultants from the medical profession for eg. if it is a medical product Select appropriate members Define responsibilities and allocate resource- team contract (should include a confidentiality agreement, clarify issues about intellectual property in a group setting, obligations and rights of the members (eg. Flexible deadlines, required meetings etc.)) Establish structure for online collaboration Document customer specific technical performance requirements Refine and extend the requirements using checklist and scenario planning Determine demands and wishes Differentiate between requirements that are common to the product family and requirements that vary with the members (mass customization) Classify the requirements that vary with the members of the family into those that require internal variety and those that require external variety. Significant demand for internal variety could indicate the necessity to create two product families rather than two products. Requirements list-present a synopsis of the planned product on the website for current and prospective customers to view and provide feedback. Group feedback at all major decisions

Phase II Requirements list Abstract to identify the essential problems Establish function structures:overall functions and subfunctions in context of design and manufacturing abstractions Search for working principles that fulfill the subfunctions using simulation tools and rapid/virtual prototyping Combine working principles into working structures Select suitable combinations using selection DSP technique for a sufficient solution Firm up into principle solution variants Draft computer model Evaluate variants against technical and economic criteria-Check: Can internal variety, if any be satisfied within th same product family? Principal solution Group feedback at all major decisions

Phase III Concept Identify embodiment determining requirements Identify fixed and variable driving parameters of design Produce scale 3-D CAD models of spatial constraints Identify embodiment determining main function carriers Develop preliminary layouts and form designs for the embodimentdetermining main function carriers Select suitable preliminary layouts using compromise DSP in Quantitative Selection Develop preliminary layouts and form designs for the remaining main function carriers Search for solutions to auxiliary function carriers Develop detailed layouts and form designs for the main function carriers ensuring compatibility with the auxiliary function carriers Develop detailed layouts and form designs for the auxiliary function carriers and complete the overall layouts Evaluate against technical and economic criteria environmental and manufacturing aspects Preliminary layout Develop prototypes for preliminary layouts Optimize and complete form designs Check for errors and disturbing factors- use of compromise DSP or Multi-goal optimization. If elimination of errors is not possible, try to make the system self-correcting. Prepare preliminary parts list and production documents Beta-test, pilot strategies, use of virtual reality for early customer feedback Evaluate exportation costs Definitive layout Group feedback at all major decisions

Phase IV Definitive layout Finalize details and complete detail drawings Integrate into overall layout drawings, assembly drawings and part lists Complete production documents with production assembly, transport and operating instructions Check all documents for standards, completeness and correctness Documentation Investigate locations for fabrication, storage and sale. Check possibility of fabrication is developing countries. Evaluate need for translation of documents. Manufacture product using Green manufacture Assemble and (nondestructive) test Group feedback at all major decisions

Phase V Product platform Perform after-market survey Collect new requirements and prioritize 'nice to haves' not met in initial realization attempt Develop product road-map Iterate through Phase I-IV Next-Gen product (Product family) Evaluate continued improvement Sun-Set product Group feedback at all major decisions
