Answer:
A) Implementing the change quickly.
Step-by-step explanation:
The company's controller is basically the chief accountant of the company. In this case, he/she is trying to focus on lowering costs and suggest a formal budgeting process might help. This is an essential thing that should have been done before, probably since the company started operating.
When essential and important activities are not carried out within a company, and suddenly someone realizes that it must be done, it may be seen as something bad. E.g. if it was really so important, why was it never done before?
As all important things, they cannot be rushed, and they have to be done with the largest possible support within the organization. This includes both management (who will feel pressured) and employers (who might believe it is a way to determine who should be fired).
