Answer:
investing in managerial productivity and enjoying experience curve effects.
Step-by-step explanation:
Companies can pursue differentiation from many angles including providing a unique competitive product taste, executing superior customer service, providing products that ensue luxury and prestige, ensuring engineering design and performance benefits; but not investing in managerial productivity and enjoying experience curve effects.
Productivity does not imply differentiation, it is defined as a ratio between the output volume and the volume of inputs.
Differentiation involves making products superior to competitors' products.
It can be argued that as firms try to increase productivity, they will compromise on quality and differentiation because differentiation will require more time and resources which could mean lesser outputs.
Hence improved productivity is not a means of differentiation.
