2 questions regarding "Management"

(1) The roles of manager:

Control by creating and maintaining a positive flow of work by utilizing what resources and facilities are available
Lead by developing and cascading the organizations strategy/mission statement to all staff
Organize resources such as facilities and employees so as to ensure effective production of goods and services
Plan by prioritizing customer, employee and organizational requirements
Maintaining and monitoring staffing, levels, Knowledge-Skill-Attitude (KSA), expectations and motivation to fulfill organizational requirements
Performance Measures for the measurement of performance and consideration of efficiency versus effectiveness
(2) In business, facility management is the management of buildings and services. The services are sometimes considered to be divided into "hard services" and "soft services." Hard services includes such things as ensuring that a building's air conditioning is operating efficiently, reliably, safely and legally. Soft services includes such things as ensuring that the building is cleaned properly and regularly or monitoring the performance of contractors (e.g. builders, electricians). The term "facility management" is similar to "property management" but often applied only to larger and/or commercial properties where the management and operation is more complex. Some or all of these aspects can be maintained by data-rich computer programs.
It is the role of facility management to ensure that everything is available and operating properly for building occupants to do their work.The facility manager generally has the most influence upon the quality of life within a facility. Facility management may range from the small scale (e.g. single small building custodial services) to the large scale (such as Johnson Controls' operation of Chrysler manufacturing) or even on an international scale (e.g. global service provision to a multinational corporation). Some facility management companies (e.g. Regus) have grown to simply provide environments which other organisations may rent on demand in order to do business in a "hotel" environment.
One definition provided by the International Facility Management Association (IFMA) is:

"A profession that encompasses multiple disciplines to ensure functionality of the built environment by integrating people, place, process and technology."
Another broader definition provided by IFMA is: "The practice or coordinating the physical workplace with the people and work of the organization; integrates the principles of business administration, architecture, and the behavioral and engineering sciences."
In the UK and other European countries facilities management has a wider definition than simply the management of buildings and services. The definition of FM provided by the European Committee for Standardisation (CEN) and ratified by BSI British Standards is:

“Facilities management is the integration of processes within an organisation to maintain and develop the agreed services which support and improve the effectiveness of its primary activities”.
The British Institute of Facilities Management has formally adopted the CEN definition but also offers a slightly simpler description:

"Facilities management is the integration of multi-disciplinary activities within the built environment and the management of their impact upon people and the workplace".
Operations management is different from production management, it is about a product will be made from raw material to final product. Using a method to minimize the time but maximize the profit but did not reduce the quality of the product is the main theory of this management.
