d. Value chain analysis

Explanation:

The Value Chain analysis by Michael Porter has become a very integral analysis tool for companies as they aim to improve their sales and production efficiency.

Value Chain Analysis works by a company looking inwards to find out the activities it engages in to enable it sell the products that it does. They will look at what sets them apart from other competitors which is their competitive advantage and core competencies.

Using this they will know which activities to embark on and which to avoid or improve upon to enable them maintain profitability. Blackberry needs to do a Value Chain Analysis to regain a scope of its core competencies and determine potential sources of competitive advantage.
