Regarding cross$-$functional new product development teams, which statement below is true?

Without proper funding for the new product development process innovation may never be realized, so a budget must be established at the beginning to ensure the team will have the means to create and launch a successful new product.

Cross$-$functional groups should only be staffed by employees from very limited functional areas within the firm to avoid confusion and time delays due to a lack of knowledge about product develop.

The cross$-$functional team leader should have limited authority to act to avoid unnecessary expenditures.

Communication between team members should be limited to speed up the product development process.

Groupthink is the friend of new product development, so the team should be comprised of individuals from similar backgrounds.
