Then for differentiation strategy, the risk associated with it includes a customer group's decision that the differences between the differentiated product and the cost leader's good or service are no longer worth a premium price. What it means here is that firm might providing the differentiated features that exceed customers' needs and competitor can offer a better price than the cost's leader with better combination of product features. Besides that, the inability of a differentiated product to create the type of value for which customers are willing to pay for premium price is another risk where customer perceived that rivals offer the same product and maybe even with lower price. Not only that, the ability of competitors to provide customers with product that have features similar to those associated with the differentiated product, but at a lower cost is also one of the risk. Last risk is the threat of counterfeiting, whereby firms produce a cheap "knock-off" of a differentiated good or service.
The risks for both focused cost leadership and differentiation strategy are combine together. The risks include competitor's ability to use its core competencies to 'out-focus' the focuser by serving an even more narrowly defined competitive segment. Here it mean that competitor can narrow down its competitive segment than the cost leader.
