Sourcing strategy must be developed within the scope of the overall mission statement and ensure, to the extent possible, achieving the organization's objectives. It is also imperative to ensure that the strategy addresses developments throughout the supply chain; it may be economic conditions, or it may be category or commodity shortages that escalate market pricing. Use the previous elements to help you.
Create the strategy section of your sourcing plan. Remember, your strategy can change as market conditions and other factors change in the marketplace but you need to have an initial strategy so that the organization understands what plans and decisions will need to be made.
