What are the three levels of management and how they can contribute to an organizational efficiency and effectiveness?

Thanks

They are :

• Top management ( High- Level) : which contains Chairman, CEO, Stockholders, General Manager, this level responsible for putting general plan\\s, strategic plan\\s,organizational policy, each departments policy, organization; vision-mission-message.determine the size of organization, determine the targeted market, work process, form of alliances, other important & strategic decisions.
• Middle- Level : which contains departments managers and administrative manager, this level mix between implementing the procedures put by high-level and direct,manage,control,& evaluate the low- level by leading it,in order to achieve the goals are assigned by high-level, middle- level send their feedback and outputs directly to mentioned person (CEO,Chairman,GM,..)
• Low- Level : which contains executive persons, employees, teams, craws, under official name as; Supervisor, Team Leader, Branch Manager. all of them as a person or teams send their reports, feedback, inputs, achievements reports, results, diagrams to their supervisor, team leader which in his-her turn sends it (report) to Department managers which will they compile them ( reports) in one report and feedback them to high and\\or  management in hierarchy form within Organization Communication System.

If we are about contribution, i would say every small employee has a big contribution in this system by his-her ( role, achievement, work, ideas, implementation, following orders, initiative, creativity,...) just he-she should has an organizational  loyalty  and ability work with team as one spirit.

The three level of management form a hierarchy from top down to the bottom: top, middle, first level. Each level has their own respective duties. The top level task is to formulate and set goal for the company and seldom to see in the operation they just come to discuss  important things or matters pertaining companies concerns. The middle level is the one  to carry the goal that set by the top level managers such as general managers regional director etc...the first level is the managers who actually work with the employees such as store managers for examples. Each level has its own task and duties which contributes for the success and prosperity of the company. 

 . I totally agree with Mr Omar He gave a great detailed answer  

Thanks for invitation,

Totally agree with the valuable input of Mr Omar Saad.

Management does not have three levels.  It has as many as you want it to have.

However, management is often divided into three levels by commentators, and this division does have some utility in describing common structures and functions of management hierarchies.

Senior management - make big decisions

Middle management - communicate decisions down the management chain and information up it

Junior management - make the staff do the thing the senior management decided

Upper Management- responsible for controlling and overseeing the entire organization       can influence masses by setting examples and by leading from front.

Middle Management- Bridge between Upper Management & Lower Management

Can bring both managements into on page and can influence many rules & regulations of company to ease process.

Lower Management- Manages rest of staff directly reporting to them, leadership skills can bring prosperity for organization & employee.

Thank you for invitation. I agree with colleagues answer, also looking forward to new answer.
