how an organization will

recover and restore partially

or completely interrupted

critical function(s) within a

predetermined time after a

system is not operating and cannot be

used

High availability – System is

continuously operational at all times

Maintainability

Maintainability – How quickly a system

can transform to support environmental

changes

Organizations must watch today’s

business, as well as tomorrow’s, when

designing and building systems

Systems must be flexible enough to

meet all types of business changes

Portability – The ability of an application to

operate on different devices or software

platforms

Page 18: CHAPTER FIVE - Burapha University · 2013-06-06 · 16 Maintainability Maintainability – How quickly a system can transform to support environmental changes Organizations must watch

18

Reliability

Reliability - Ensures a system is

functioning correctly and providing

accurate information

Reliability is another term for

accuracy when discussing the

correctness of systems within the

context of efficiency IT metrics

Page 19: CHAPTER FIVE - Burapha University · 2013-06-06 · 16 Maintainability Maintainability – How quickly a system can transform to support environmental changes Organizations must watch

19

Scalability

Scalability - How well a system can

scale up, or adapt to the increased

demands of growth

Performance - Measures how quickly a

system performs a process or transaction

Capacity planning - Determines future

environmental infrastructure

requirements to ensure high-quality

system performance

Usability

Usability – The degree to which a system is

easy to learn and efficient and satisfying to use

MIS AND THE ENVIRONMENT

Moore’s Law - Refers to the computer chip

performance per dollar doubles every 18

months

Sustainable, or “green,” MIS - Describes

the production, management, use, and

disposal of technology in a way that

minimizes damage to the environment

Corporate social responsibility -

Companies’ acknowledged

responsibility to society

Increased Energy Consumption

Huge increases in technology use have greatly

amplified energy consumption

The energy consumed by a computer is estimated

to produce as much as 10 percent of the amount

of carbon dioxide produced by an automobile

Page 27: CHAPTER FIVE - Burapha University · 2013-06-06 · 16 Maintainability Maintainability – How quickly a system can transform to support environmental changes Organizations must watch

27

Increased Carbon Emissions

The major human-generated greenhouse gases,

such as carbon emissions from energy use, are

very likely responsible for the increases in climatic

temperature over the past half a century

When left on continuously, a single desktop

computer and monitor can consume at least 100

watts of power per hour
