Please help me with this case study, please do not copy answers from previous posts of this questions.

Four years after being appointed as Costco Wholesale's president and chief executive officer, Craig Jelinek was proving fully capable of cementing the company's standing as one of the world's biggest and best consumer goods merchandisers. His predecessor, Jim Sinegal, cofounder and CEO of Costco Wholesale from 1983 until year-end 2011, had been the driving force behind Costco's 28-year evolution from a startup entrepreneurial venture into the third largest retailer in the United States, the seventh largest retailer in the world, and the undisputed leader of the discount warehouse and wholesale club segment of the North American retailing industry at the time he retired. The cornerstone of Costco's strategy were low prices, a limited product line and limited selection, and a "treasure hunt" shopping environment.

Using your critical thinking skills, analyze the case study and evaluate Costco's strategy for growth and expansion while discussing the following issues to determine if Costco's plan is effective and what changes could be made to improve it:

• The chief elements of the Costco strategy.
• Whether their strategy is well matched to market conditions in the warehouse and wholesale retail industry.
• Craig Jelinek's mission and vision for Costco.
• The validity of Costco's core values and their contribution to the success of the company.
• Demonstrate the success of Costco's current and past financial performance using three key financial ratios.
• The competitive advantage Costco has in the warehouse and wholesale club market.
• Recommendations to sustain growth and financial performance.
