Cards Term Concept Testing Formats: Definition face to face, telephone, email, postal survey, internet Term Concept Testing: Ways to Communicate the Concept - Definition verbal description, video, storyboard, simulation, working prototype, interactive media/model renderings and sketches Term Product Architecture:  Functional elements--  Definition individual operations or transformations that contribute to the overall performance of the product Term Product Architecture:  Physical Elements-   Definition Parts, components and subassembelies that ultimately implement the products functions Term FMEA- What is it?  Definition Failure Modes Effects and Analysis began in Aerospace industry, now mainly in automobiles, used to anticipate and prevent failures from occuring  Term FMEA is most effective: Definition when it occurs before the design   should focus on prevention not detection  Term FMEA 2 types of FMEA:  Definition Design FMEA - examines functions of the system  ex: inappropriate specifications       Process FMEA  - examines the process used to create the components   ex: improper assembly, or variation in parts  Term RPN Definition Risk Priority Number - it identifies the greatest areas of concern Assesses: Occurance Severity detection of failure    RPN = Severity x Occurance x detection Term Concept Testing used for: Definition -Go/ no go decisions -choosing market  -benchmarking -forecasting demand -concept selection among alternatives  Term Concept Testing Process - Definition 1. Define purpose of the test 2. Choose a survey population 3. Choose survey format 4. Communicate the concept 5. Measure customer response 6. Interpret results 7. Reflect on results and process  Term Suvey format: Definition 1. Qualification 2. Product Description 3. Purcahse intent 4. Comments  Term Forecasting Sales Definition Q = NAP Q=sales N= number of purchases A=awareness*availibility P=probability of purchase  Term Probability Definition P = Cdef*Fdef + Cprob*Fprob   C= from competitors Fdef and F prob from survey  Term Modular Architecture: Definition -chunks implement one or a few chunks -interactions are well defined   Advantages: simplicity reusability  Term Integral Architecture: Definition -multiple chunks, and chunks may perform many functions -poorly defined   Advantages: low cost, high performance  Term Three levels of architecture: Definition system subsystem components Term Architecture determines: Definition -ease of product variation -feasibility of customer modification  Term Definition
