the difference between a product line approach and a customer segmentation approach to marketing
The Difference Between a Product-Line Approach and a Customer Segmentation Approach to Marketing
  • In the product line approach (technology-driven), products are spawned from the technology to create wants, while in the customer segmentation approach (market-driven), products are assembled to meet predetermined needs of customer segments.
  • In the product line approach, the systems development and the delivery function (marketing) are the responsibility of the managers of technology. Product marketing by the producers in a popular structure for entrepreneurial products (leading edge technologies) and organizations in early growth.
  • In the customer segmentation approach, the delivery function (marketing) is customer-oriented and market-driven (instead of technology-driven). Products are developed to meet well defined needs by employing only those technologies that are necessary to do so.

SMDS
  • Switched Multimegabit Data Services is a switched service for MANs that uses cell relay technology.
    • The service is now being offered by local telephone companies and promoted for linking LANs within metropolitan areas.
    • Long distance carriers are also looking into offering it between MANs, as is Stanford University to transfer medical images (such as CAT scans) and earth resources mapping images among buildings on the campus
characteristics of interorganizational systems
Characteristics of Interorganizational Systems
  • At least two parties to create an IOS, thus the partners in the venture must have a willingness to cooperate and the ability to perform the work.
  • Standards play a major role in permitting many IOS efforts to get off the ground.
  • Education of potential partners is often more of a hurdle than the technology.
  • Coordination of joint systems often entails using a third party.
  • The various efforts need to be synchronized.
  • Work processes are often re-evaluated.
  • Technical issues are minor compared to the relationship issues.
  • IOS often requires more openness than traditional system development.
interoperability
Interoperability
  • The capability for different machines, using different operating systems, on different networks to work together on tasks-exchanging information in standard ways without any changes in the command language or in functionality and without physical intervention.
investment strategy analysis approach to studying current expeditures
Investment Strategy Analysis Approach To Studying Current Expeditures
  • The true “intensity of beliefs” about the use of technology, says Norton. It allows the managers to stand back from the business, see where the investments are currently being made, and then decide where they should be made in order to align the information systems investment with the business strategy.
problem solving approach to information systems
Problem-Solving Approach to Information Systems
  • Techniques that can be used to enhance several I/S/ planning approaches.
  • Recognizing the problem, analyzing problem information to develop a useful problem definition, generating solutions, and selecting and implementing a solution.
  • Opportunity identification
  • Nonlinearity and recursiveness of the model, and the identification of a variety of creativity techniques for each problem-solving phase.

Couger’s three variants to the classical method

critical success factors in the systems planning process
Critical Success Factors in the Systems Planning Process
  • Critical success factors are the few key areas of the job where things must go right in order for the organization to flourish. Factors are critical for accomplishing the objectives, and are also used to determine the prime measures for satisfying each factor.
examples of distributed systems structures
Examples of Distributed Systems Structures
  • A hierarchy of processors is the most familiar data processing structure, with a large, controlling computer at the top of the hierarchy and PCs or terminals at the lowest level. The important characteristic of its structure is that the mainframe, or host computer, is the central, and controlling, component.
  • Decentralized stand-alone systems do not really form a distributed system at all. They are basically a holdover from the 1960s, when departments put in their own departmental computers, with no intention of connecting them to other systems. Hence, they are decentralized, not distributed.
  • Systems based on a local area network (LAN) have become widely used as the basis for distributed systems. This approach began in the office system arena with LANs providing the links between PCs, print servers, and gateways to other networks. This structure has no hierarchy, processors communicate on a peer-to-peer basis.
  • LAN-based systems that communicate with mainframe-based systems another structure for distributed systems. It is essentially a combination of the hierarchy approach (for mainframe-based processing) and the LAN-based system (in offices).
  • Cooperative systems are the newest member of the distributed system family. A cooperative system melds and extends the previous approaches. All the components are linked to each other via interconnected LANs and wide area networks (WANs). In essence it is an internet-a network of networks. All machines are equal; no machine is at the hub.

attributes of innovations
Attributes of Innovations

Relative advantage - The innovation is technically superior (in terms of cost, functionality, “image”, etc.) than the technology it supersedes.

Compatibility - The innovation compatible with existing values, skills, and work practices of potential adopters.

Complexity - The innovation is relatively difficult to understand and use.

Trialability - The innovation can be experimented with on a trial basis without undue effort and expense; it can be implemented incrementally and still provide a net positive benefit.

Observability - The results and benefits of the innovation’s use can be easily observed and communicated to others.

economic factors impacting technology adoption
Economic Factors Impacting Technology Adoption

Prior Technology Drag - A prior technology provides significant network benefits because of a large and mature installed base.

Irreversibility of Investments - Adoption of the technology requires irreversible investments in areas such as products, training, and accumulated project experience.

Sponsorship - A single entity (person, organization, consortium) exists to define the technology, set standards, subsidize early adopters, and otherwise promote adoption of the new technology.

Expectations - The technology benefits from an extended period of widespread expectations that it will be pervasively adopted in the future.

changes in traditional environments
Changes in Traditional Environments
  • Many organizations are emphasizing teams to accomplish major tasks and projects.
  • Information workers are increasingly mobile.
  • Organizations are examining what they should do internally, and what should be done by some other organization.
  • Corporations are shifting their emphasis from financial capital to human capital.
  • New forms of self-managing groups are appearing.
  • A coming labor shortage will result in more jobs for women, part-time older people, and the poor and disadvantaged.

According to Naisbitt and Aburdene

procedure based vs goal based information systems
Procedure-Based vs. Goal-Based Information Systems

Procedure-Based Activities:

  • Tend to consist of high volumes of transaction in which each has relatively low cost or value.
  • Are based on well-defined procedures (or algorithms) where the outputs are well-defined too.
  • Are based on the handling of data.

Goal-Based Activities

  • Tend to handle fewer transactions of higher value or cost.
  • Are based on ill-defined processes (or heuristics) and the outputs are less defined as well.
  • Tend to focus on defining the problems and the end results or goals with effectiveness stressed in achieving them.
  • Are based on the handling of concepts.
