acquisition ; development

Explanation:

Heterogeneity refers to the state where the character if different of each and every product.

These days the consumer or the customers have heterogeneity and with basic product development each time you cannot full fill the need of every customer.

For that you need to provide complete other product sometime. Therefore, as per Professor Fader one should seek more opportunity through acquisition, that does not mean that you should stop development. Development is also needed, and shall not be stopped. That is always the icing on the cake.
