Disclosed is a strategy planning system for displaying a narrative content associated to an optimal strategy to be implemented for a business opportunity. The strategy planning system comprises a strategy computation module, a strategy synthesis module, and a strategy customization module. The strategy computation module determines an optimal strategy, amongst a set of strategies, to be implemented for a business opportunity. The strategy synthesis module generates a narrative content for the optimal strategy by selecting a predefined narrative template, comprising a predefined content, associated to the optimal strategy. Post selection of the predefined narrative template, a narrative description for the optimal strategy may be created by performing a Natural Language Generation (NLG) technique on metadata associated to the impact analysis. Subsequently, the narrative description may be appended to the predefined content in order to generate the narrative content for the optimal strategy. After generating the narrative content, the strategy synthesis module displays the narrative content, associated to the optimal strategy to be implemented for a business opportunity, to a user.
