I need a case study written with a in-depth supplier analysis (cost analysis, internal/external factors, other key success factors) that will determine when E-charger supplier Spin Masters Toy company should choose. Attached is the directions/instructions (what is a case analysis) , the paper itself (ACTUAL PAPER FROM HBR), chapter notes which outline a few concepts to explore (chapter 13 and 12), and then I have attached a few examples and other papers that should help quickly come to a decisive conclusion (but these are not super important).
