Goals of Balance Scorecard under Innovation and learning Perspective? [Provide detail explanation]

How would you measure the resistance of employees during the innovation process?

Explain.

Please Give a report about the new innovation of hydrogels towards cartilage repair.

why you think people initially “freaked out” about this technological innovation.

Do you agree that a systematic policy is the only way to overcome resistance to innovation?

Discuss people/innovation perspective as one of the dimension of balanced scorecard in hotel context
