Answer:
Data related to the client, business methods and processes (tools used), new inventions and discoveries, client contract information (contract price, performance obligations)
Step-by-step explanation:
In todays world where companies compete with each other on the basis of advertisement and promotions it is highly important that the confidential data related to the business must not be disclosed.
If the confidential information is disclosed by the employee, it could not only hurt the reputation of your business but would also effect the business of your client.
As an advertising agency, you have tons of data with you which include primary and secondary research data and confidential data related to the client. It is mandatory that such confidential data related to the client which the client has only given to us based on trust should not be disclosed by the employee.
The employee should not disclose the business methods/processes and the tools and mediums used by the company to promote the clients products as if they do so, they would lose the competing advantage and the competitors could use the same tools too.
If the company has invested in research and development and came up with new tools and applications to promote its clients products then those new inventions and discoveries should not be disclosed as doing so would ruin all the money invested and hence would lead to the invention or discovery being copied by the competitors.
Employees should not reveal the information related to previous or other clients contracts as this would then lead to a complication as the competitor could offer the same service in a much lower price and the company could lose the client.
There are many other factors which should not be disclosed but these are the main ones to help you understand the importance of confidential information.
