Greenbell Software Inc Suppose the Overall Utility (Sum of Part-Worths) of the Current

Greenbell Software Inc. conducted a study on its smartphone products in the market to determine which phone has the best features in terms of three prominent attributes: operating system of the phone (A or B), RAM (512MB or 1GB), and the rear camera specifications (3MP, 5MP, or 7MP). A sample of eight customers participated in the study and provided the following part-worths for each of the above attributes.
​ $$\begin{array} { | c | c c | c c | c c c | } &{ \text { Operating System } } && { \text { RAM } } &&& { \text { Camera } } \\\hline \text { Consumer } & \text { A } & \text { B } & 512 \mathrm { MB } & 1 \mathrm {~GB} & 3 \mathrm { MP } & 5 \mathrm { MP } & 7 \mathrm { MP } \\\hline 1 & 25 & 29 & 20 & 45 & 18 & 18 & 15 \\2 & 35 & 32 & 30 & 35 & 27 & 19 & 13 \\3 & 45 & 35 & 30 & 30 & 15 & 25 & 30 \\4 & 55 & 65 & 25 & 45 & 25 & 20 & 35 \\5 & 40 & 40 & 35 & 40 & 20 & 25 & 30 \\6 & 30 & 47 & 40 & 35 & 15 & 20 & 15 \\7 & 35 & 45 & 30 & 30 & 20 & 20 & 20 \\8 & 25 & 25 & 25 & 30 & 25 & 30 & 30 \\\hline\end{array}$$ Suppose the overall utility (sum of part-worths) of the current favorite Greenbell smartphone is 100 for each consumer. What new product design will maximize the share of choice for the eight consumers in the sample?
