Hi there.. I have a homework to ask

1. Help me to know how to identify and evaluate the value proposition and value delivery of a company (in my case: Lululemon Athletica)
2. My teacher ask me to give a critical evaluation of the value proposition of this company, including sources and types of value created and how the value corresponds to the needs of target customer segment. How should I explain this.
3. Can you help me to understand what is value delivery system how should I know whether the value delivery system of the company aligns with its value proposition.
