Which is more important in an organization hierarchy, sales department or marketing department and why?

In a organisation all employees and departments should be working towards one united goal; to further the organisation. A company that works as a team without hierarchy will prove more successful than one with un healthy competitiveness dividing the company. 

Some strategies of the Marketing Department are for a long term basis and required generate leads, and for the short term it has to work hand-in hand.

In any Company (( Sales are the Heart of Company )) but no one never and ever can succeed alone , but all divisions MUST work together, that's why its called company.   

The hierarchy of authority in an organization is designed to benefit the company and the employees. The company grows with the strength of a competent managerial staff, and employees look to management to provide career development. A hierarchy is also a method of maintaining managerial integrity. When someone becomes a manager, she must prove to be competent, or else she will experience employee turnover. The hierarchy of authority in an organization is important to the sustained success of the company.

Managerial accountability in the hierarchy of authority should not be used to point fingers and accuse staff members of being incompetent. A clearly defined hierarchy creates a path of accountability for every project and activity within the company. For example, an accounts receivable associate reports to an accounting manager, who reports to the operations manager. If the accounts receivable system is consistently reporting erroneous information, then you can follow the hierarchy of authority to determine who is responsible for the errors. The accounting manager may be approving payment logs that have errors on them, or the operations manager may be failing to detect a problem with the accounting software during monthly audits of the system. The point is to find the point of failure, repair it and then allow the responsible person to learn from the experience.

Employee development happens at all levels of an organization. Employees look to the managerial staff to help develop work skills, the managers work with company executives to improve managerial performance, and the executives draw on the experience of company owners for business guidance. The hierarchy of authority helps an employee to understand who he is to receive guidance from, and it helps that employee to see where his manager is getting her career development from. This is why competence at all levels of the corporate hierarchy is important.

The hierarchy of authority provides a clear career path for each employee in the organization. The outline of executive, managerial and supervisory positions within the company can help employees to determine their career goals and what kind of move up the corporate ladder they would like to take. Executives and managers can use the hierarchy as motivation for employees that show supervisory or managerial potential to perform at a high level of productivity.

A hierarchy helps to establish efficient communication paths between employees, departments and divisions of the company. The manager of each department becomes the departmental administrator, and any information that is relevant to the department is given to the manager. The manager can either act on the information or delegate it to someone within her staff. Information can be effectively distributed through company managers rather than trying to contact each individual employee. The manager's understanding of her staff and the structure of her department makes her the ideal person to improve communication to her department.

Sales Department & Marketing Department, both have equal importance in an organization hierarchy.

One is incomplete without the other. Marketer are highly analytical, data oriented, and project focused. They’re all about building competitive advantage for the future…Salespeople, in contrast, spend their time talking to existing and potential customers. They’re skilled relationship builders, they want to keep moving.

Both enjoys equal importance............... Marketing is like a BRAIN and Sales is like LIMBS........... 

Both departments are2 sides of the same coin and both are interdependent on each other.

If Marketing is creation of strategies, Sales implement them and remember all strategies are as good as implemented.

If the company can inculcate a culture where both the departments work in absolute harmony and transparency it is an ideal condition for success and anything less leads to a certain faliure.
