management

there are two questions, each questions must be answered with a maximum of 300 words. Thank you.

1. What is aggregate planning? What is the main difference between demand and supply strategies for managing production quantities using aggregate planning? How might a pricing strategy work to increase product sales for intermediate term planning? How might a manager vary the workforce size to match production rates?

2. Describe three reasons Procurement matters to organizations. Then, define the sourcing decision and explain the difference between in-house sourcing and outsourcing. Finally, discuss which of the sourcing options (single, multiple, cross, dual, and sole) you believe offers an organization the most versatility for procuring the resources it needs.
