How to create great bond/understandings between different departments of an Company which is necessary for success for any Company?

I would like to put as follows:

• Creation of common understanding of core business and how each employee is related to the final output. This could be created through all staff meeting (office based or plant based).
• When a project is launched, take opinion of all department heads and relevant core staff.
• Conduct weekly meeting with all department /unit heads to update their position/progress and let them express what support they expect. This will create a overall good relationship among all. 

Create the great bonds & understanding among all Departments in the Company by consideration the following points :

1- Increasing the communication skill for all staff of the departments

2- Encourage the personal initiatives to develop the business and making the team spirit prevalent in the working system of all Departments

3- Participation all Departments in the period meetings to exchange the points of views and discussion new strategy and policy of the company

4- Organization the internal session and seminars to increase opportunities of the mutual talking and discussions each other and reaching out in the ideas and orientations

5- Inspire the responsibility spirit in all staff of departments that success and failure for all in order to make all staff of the company are carrying the responsibililty and working gather to reach the goals

The best formal way to create bond and understanding between different departments of a company is by creating service agreements which are understood by both ends of the interactive departments, and the service level maintenance is controlled by appointed supervisor by both ends. 

thanks for the information

I agree with colleagues answer

What I am reading here is good ...typical text book .... but the best way is to show that you can do what you say... than assist other departments ... at times you have to take invitations to walk through a department and show that supervisor what he/she is looking for ....

at times you endure nasty emails answer them in a professional manner to make out of an enemy a friend.

One hand washes the other ... do favors (professionally only) and when you need something done most will repay your kindness..

I have seen a company divided one department fighting against an other and 2 years later you see how these departments working together ... a change in management, attitude of all employees and the willingness to change for the better made this company a better place in business   

Assign common goals to different teams. For example, a concept called SMarketing is an integrated approach towards marketing and sales teams, assigning them common goals and rewards to help them see the goal of the company and not their teams. 

Thanks for the invitation. I second the answers given by experts here.
