Final answer:
The favorable condition for Mandy to facilitate cultural change in her company is that it is young and small, which likely means a more adaptable culture.
Step-by-step explanation:
The favourable conditions that might help facilitate cultural change in Mandy's company is option B) The organization is young and small. Given that the company is only five years old and consists of 150 people, it is likely to have a more flexible and malleable culture compared to older, larger organizations. Additionally, organizational culture is influenced by shared beliefs, values, and practices, which can be more readily shaped and adapted in a smaller, younger company. Mandy should look to leverage the recent shock from the hostile takeover and harness the current mindset of change among the employees to guide the cultural change.
