Additionally, the implication takes note of the risk level that is associated with the established significant parameters (Budd, 2006). From the questionnaire generated, the customer requirement for key ring torch includes a metal shell body having different colors, 58 by 20 MM size, LED light for lighting, nice color, and 4pc button cells that are included on the key ring. I used the questionnaire over the other methodologies because the responses are collected in a standardized manner; therefore, this method is more objective, certainly more than the Focus Group Discussion and Interviews. Generally, the method is relatively faster in collecting information than the interviews and the FDG. However, in some cases the method took a longer time to develop, apply and to analyze. Additionally, the information can be easily collected from a larger group portion. The potential is not always realized because the questionnaire returns are usually very low. However, the rates of return can be improved ones the questionnaire is responded and delivered on time. The questions in the questionnaire are outlined in the appendices (Cather, 2001). . Design Parameters Some of the design parameters for the keyring torch include type of material body color of the keyring torch Led lights Switch battery size packing mechanism flash mode Charge lead time. Using a Focus Group Discussion, the major design parameters include the material used, the body color, and the charge lead time on that order. Some of the key features of Key ring torch include the unbreakable LED light, a lithium batters having a shelf life of one year, burn time of over ten hours, the lay on the chain of the key, and small and lightweight. Some of the application of the key ring include the lighting for driver, emergency for office and home, chart reading for the pilots and astronomers, and outdoor tasks like hunting, camping, and fishing. The key ring torches are bright idea for promoting a company. The customer key ring can be customized with a company’s logo or even the message. From the Focus Group Discussion it was evident that the clients preferred aluminum alloy material, blue, pink, red, and silver body color. The brightness for the LED light is 13000mcd, a button switch, a battery of 3*LR44, a size of 58*20MM, key ring flash mode, and the charging leading time of five to seven days. The clients required the packing to be in an inner box of 500 pieces, with cumulative weight of 12.5 Kg. FDG conducted is outlined in the appendices Design Specification Name Parameter Specification Features Body color Blue, Pink, Silver, Green, and red painting Material Aluminum alloy Switch Button LED Lights Brightness of 13000mcd Size 58 by 20 MM Battery 3*LR44 Packing 1 piece/OPP, 100pcs/CTN, NW 12.g Kg Charge Lead time 5-7 days Flash mode Key ting Details of Packing Packing Inner Packing Outer Packing Meas G/N.w 1 pcs/ bag 100 pieces /inner box 500 pieces per Carton 32*23*24cm 13.5/ 12.5 Kg Design Specification and the customer requirement The design is based on the outlined specification. The reliability requirement of the key ring torch was part of the technical specification document. The company set the requirement for the key ring torch. The reliability of the product is not easy to specify. It is very easy to use the qualitative language like the needs of the product needs to exceed the expectation of the client. The key ring torc ...Show more
