Difference Between Office Order, Circular & Notice

Hi Everyone,
I would like to know exact difference between the Office Order, Circular & Notice.
Please help me to provide the clarity amoungst above three words.
Regards,
Niket

Dear Niket,
Office Order: - issued by competent authority. Office order contains instructions related to office works, change of working hours, instruction on closed holidays, message by senior authorities when they take over some organisation, promotions etc. Office orders are issued periodically like every Monday or on every 1st of month etc. The sequence of the information is pre-decided.
Circular: - An advertisement (usually printed on a page or in a leaflet) intended for wide distribution. It need not be issued by competent authority but generally it is issued by officers or managers. Circulars are for specific purpose or event like meeting, or any other event.
Notice: - A sign posted in a public place as an advertisement. When Govt authorities issue some communication, it is also called as notice e.g. notice by labour officer.

Re: Difference between Office Order, Circular & Notice
Dear Niket,
Office Order: in short, an office order has an element of "order" passed by the issuing authority intended to be followed by the target group of viewers concerned.
Circular:There is no order of any authority. It is just an information about some rules, regulations or routine process of circulating some information to intended viewers for being aware about the same.
Notice: This is also a kind of circulation of some information about an event/occurence which has already occured or is going to occur within in a short period.The retention time of a notice is generally short.

"Office Order" is mandatory of compliance by all. "Circulars" is an information for all. "Notice" is an advisory for all!
