Explain why information systems are so indispensable in concern today: Information systems are a foundation for carry oning concern today. In many industries. endurance and the ability to accomplish strategic concern ends are hard without extended usage of information engineering. Businesss today use information systems to accomplish six major aims: operational excellence. new merchandises. services. and concern theoretical accounts. customer/supplier familiarity. improved determination devising. competitory advantage. and twenty-four hours to twenty-four hours survival
Define an information system from both a proficient and a concern position. From a proficient position. an information system collects. shops and distributes information from an organization’s environment and internal operations to back up organisational maps and determination devising. communicating. coordination. control. analysis. and visual image. Information systems transform natural informations into utile information through three basic activities: input. processing and end product.
From a concern position. an information system provides a solution to a job or challenge confronting a house and represents a combination of direction. organisation and engineering elements. The direction determination of information systems involves issues such as leading. scheme. and direction behaviour. The engineering dimension consists of computing machine hardware. package. informations direction engineering and networking/telecommunications engineering ( including the cyberspace ) . The organisation dimension of information sytems involves issues such as the organisations hierarchy. functional fortes. concern procedures. civilization and political involvement groups.
Identify and depict the three dimensions of information systems: Organizations
Cardinal elements of organisations – people/structure/business process/politics/culture -orgs have constructions – different degrees and fortes
Upper – managerial/professional/technical
Lower – operational forces
Senior direction – makes long rate strategic determinations about merchandises and services and fiscal public presentation Middle direction – carries out plans and programs of senior direction Operational direction – proctors day-to-day activities of concern
Knowledge workers – applied scientists. scientists. designers – design merchandises and services and make new cognition for house Data works – secretaries. clerks – do paperwork
Production or service workers – produce merchandise and present service
Business maps specialized undertakings performs by concern orgs -sales and marketing – sell
-mfg and production – manage assets
Human resources – attract. develop. keep labour force. records
-make sense of the state of affairss faced
-exercise responsible leading
-create new merchandises and services ; even re-create organisation from clip to clip
IT is a tool directors cope with alteration
Computer hardware – physical equipment used for input. processing and end product -includes computing machines. input. end product and storage devices. telecommunication devices
Data direction – package regulating the organisation of informations on physical storage media
Network and telcom engineering – physical devices and package – links to hardware
Network – links 2 or more computing machines to portion informations or resources Examples: pressman
Internet – most used web
Intranet – internal corp based on cyberspace engineering
Extranet – private intranets extended to authorise users outside of organisation -firms use to organize activities with other houses for doing purchases. coaction on designs and other inter-organizational work
World broad web
IT substructure – provides foundation/platform on which the company builds it’s IT on -orgs must carefully plan and pull off it’s IT so it has the tech services it needs for the work it wants to carry through
Assess the complementary assets required for information engineering to supply value to a concern. In order to obtain meaningful value from information systems. organisations must back up their engineering investings with appropriate complementary investings in organisations and direction. These complementary assets include new concern theoretical accounts and concern procedures. supportive organisational civilization and direction behaviour. appropriate engineering criterions. ordinances. and Torahs. New information engineering investings are improbable to merchandise high returns unless concerns make the appropriate managerial organisational alterations to back up the engineering.
Identify and describe modern-day attacks to the survey of information systems and distinguish between computing machine literacy and information systems literacy. page 18
Define and describe concern procedures and their relationship to information systems. A concern procedure is a logically related set of activities that defines how specific concern undertakings are performed. and it represents a alone manner in which an organisation coordinates work. information. and cognition. Directors need to pay attending to concern procedures because they determine how good the organisation can put to death its concern. and they may be a beginning of strategic advantage. There are concern procedures specific to each of the major concern maps. but many concern procedures are cross-functional. Information systems automate parts of concern procedures and they can assist organisations redesign and streamline these procedures. Describe the information systems back uping the major concern maps: gross revenues and selling. fabrication and production. finance and accounting. and human resources. Page 45 ESS. DSS. MIS. TPS
Measure the function played by systems functioning the assorted degrees of direction in a concern and their relationship to each other. Systems functioning operational direction are dealing treating systems. such as paysheet or order processing that track the flow of the day-to-day everyday minutess necessary to carry on concern. Management information systems and decision-support systems support in-between direction. Most MIS studies condense information from TPS and are non extremely analytical. DSS support direction systems that are alone and quickly altering utilizing advanced analytical theoretical accounts and informations analysis capablenesss. Executive support systems support senior direction by supplying informations that are frequently in the signifier of graphs and charts delivered via portals utilizing many beginnings of internal and external information.
Explain how enterprise applications and intranets promote concern procedure integrating and better organisational public presentation. Enterprise applications ( endeavor systems. supply concatenation direction systems. client relationship direction systems. and knowledge direction systems ) are designed to organize multiple maps and concern procedures. Enterprise systems integrate the cardinal internal concern procedures of a house into a individual package system to better coordination. efficiency and determination devising. Supply concatenation direction systems help the steadfast manage its relationship with providers to optimise the planning. sourcing. fabrication. and bringing of merchandises and services.
Customer relationship direction uses information systems to organize all of the concern processes environing the firm’s interactions with its clients to optimise steadfast gross and client satisfaction. Knowledge direction systems enable houses to optimise the creative activity. sharing. and distribution of the cognition. Jobs where interaction is the primary value-adding activity benefit from coaction and communicating systems. Intranets and extranets use Internet engineering and criterions to assemble information from unrelated systems and present it to the user in a Web page format. Extranets make parts of private corporate intranets available to foreigners.
Assess the function of the information systems map in a concern. The information systems section is the formal organisational unit responsible for information engineering services. It is responsible for keeping the hardware. package. informations storage. and webs that comprise the firm’s IT substructure. The section consists of specializers. such as coders. systems analysts. undertaking leaders. and information systems directors. and is frequently headed by a CIO.
