Computerized maintenance management system

Computerized maintenance management system (CMMS) is also known as computerized maintenance management information system (CMMIS).

A CMMS software package maintains a computer database of information about an organization’s maintenance operations, i.e. CMMIS – computerized maintenance management information system. This information is intended to help maintenance workers do their jobs more effectively (for example, determining which machines require maintenance and which storerooms contain the spare parts they need) and to help management make informed decisions (for example, calculating the cost of machine breakdown repair versus preventive maintenance for each machine, possibly leading to better allocation of resources). CMMS data may also be used to verify regulatory compliance.

CMMS packages may be used by any organization that must perform maintenance on equipment, assets and property. Some CMMS products focus on particular industry sectors (e.g. the maintenance of vehicle fleets or health care facilities). Other products aim to be more general.

Facility management

Facility management (or facilities management or FM) is an interdisciplinary business function that coordinates space, infrastructure, people and organization. It is often associated with the administration of office blocks, arenas, schools, sporting complexes, convention centers, shopping complexes, hospitals, hotels, manufacturing and shipping. Facilities management currently represents about 5% of global GDP. Its relationship to the human resources, real estate and information technology functions of an enterprise has increased.

FM represents a wider range of activities than just business services and these are referred to as non-core functions. They vary from one business sector to another. In a 2009 Global Job Task Analysis the International Facility Management Association (IFMA) identified the core competencies of facility management as:

Asset management

Asset management, broadly defined, refers to any system that monitors and maintains things of value to an entity or group. It may apply to both tangible assets such as buildings and to intangible assets such as human capital, intellectual property, and goodwill and financial assets. Asset management is a systematic process of deploying, operating, maintaining, upgrading, and disposing of assets cost-effectively.

The term is most commonly used in the financial world to describe people and companies that manage investments on behalf of others. These include, for example, investment managers that manage the assets of a pension fund.

Alternative views of asset management in the engineering environment are: the practice of managing assets to achieve the greatest return (particularly useful for productive assets such as plant and equipment), and the process of monitoring and maintaining facilities systems, with the objective of providing the best possible service to users (appropriate for public infrastructure assets).

Software

Computer software also called a program or simply software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of computer programs, libraries and related non-executable data (such as online documentation or digital media). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other.

At the lowest level, executable code consists of machine language instructions specific to an individual processor—typically a central processing unit (CPU). A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also (indirectly) cause something to appear on a display of the computer system—a state change which should be visible to the user. The processor carries out the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction, or interrupted.
