Question 1

Semistructured and unstructured decisions are challenging because they involve multiple criteria,and often users have to choose between conflicting objectives.

Accepted Answer

Semistructured and unstructured decisions are challenging because they often involve subjective and complex factors that can result in conflicting objectives, making it difficult for users to make the best decision.

Question 2

A database management system (DBMS)is used for creating,modifying,and maintaining the database.

Accepted Answer

A database management system (DBMS) is specifically designed for creating, modifying, and maintaining databases. It provides a software interface for users to interact with the database, and manages the storage, retrieval, and manipulation of data within the database. Therefore, it is true that a DBMS is used for creating, modifying, and maintaining the database.

Question 3

DSS uses the what-if analysis feature to support decision making.

Accepted Answer

DSS or Decision Support System uses the what-if analysis tool to simulate different scenarios, enabling decision-makers to choose the best option based on predicted outcomes.

Question 4

Information technology provides a high level of support for the design phase of decision making.

Accepted Answer

The answer of Information technology provides a high level of...

Question 5

Criteria are goals and objectives that decision makers establish in order to achieve certain performance.

Accepted Answer

Criteria are specific targets or goals that decision makers set to measure performance and progress towards achieving a specific objective. They provide a benchmark against which actual performance can be measured and evaluated.

Question 6

A DSS should use both internal and external data.

Accepted Answer

A DSS should incorporate both internal data (such as historical sales data, customer profiles, and inventory data) and external data (such as market trends, competitor data, and economic factors). This allows for a more comprehensive analysis and informed decision-making process.

Question 7

A model builder is the liaison between users and designers.

Accepted Answer

A model builder is responsible for understanding and translating user requirements into design specifications that can be implemented by designers, therefore acting as the liaison between the two.

Question 8

Each type of management support system is designed with its own goals and objectives.

Accepted Answer

Each type of management support system is designed to address specific business needs and goals, and therefore has its own unique set of objectives.

Question 9

In the design phase,a decision maker examines the organization's environment for conditions that need decisions.

Accepted Answer

In the design phase, a decision maker develops possible solutions to a problem, not examining the environment for conditions that need decisions.

Question 10

The costs and benefits of decision support systems can be difficult to assess because these systems are focused on effectiveness rather than efficiency.

Accepted Answer

Decision support systems are designed to improve the quality of decision-making, which may not always result in immediate cost savings or efficiency improvements. The benefits of these systems are often intangible, such as improved accuracy and reduced risk, which can make it difficult to quantify their overall impact on an organization. Therefore, assessing the costs and benefits of decision support systems can be challenging.

Question 11

A DSS should incorporate the human element as well as hardware and software.

Accepted Answer

The answer of A DSS should incorporate the human element...

Question 12

Information technologies are a major support tool for making structured decisions.

Accepted Answer

Information technologies, such as data analysis tools and decision support systems, can help in breaking down complex information into manageable segments, allowing decision-makers to make more informed decisions. Hence, they are a significant aid in making structured decisions.

Question 13

Unstructured decisions are often used in sales forecasting.

Accepted Answer

The answer of Unstructured decisions are often used in sales...

Question 14

A DSS can do a follow-up assessment on how well a solution is performing.

Accepted Answer

A DSS can provide post-implementation analysis in order to evaluate the effectiveness of a solution. This would involve assessing whether the solution is meeting the predefined objectives and whether the anticipated outcomes are being achieved. This data can help decision-makers to make necessary adjustments and improvements to ensure that the solution is optimized for success.

Question 15

A managerial designer defines issues that involve the technological aspects of the system.

Accepted Answer

A managerial designer focuses on organizational and managerial aspects, not technological ones.

Question 16

The benefit of improving communication and interactions between management and employees is easy to quantify using a DSS.

Accepted Answer

Quantifying the benefits of improved communication and interactions involves subjective measures and qualitative factors, which are not easily captured by a Decision Support System (DSS).

Question 17

Generally,information technologies are more useful in the design phase than in the intelligence and choice phases.

Accepted Answer

Information technologies play a crucial role in the intelligence and choice phases as they provide access to data and analysis tools that aid decision-making. In the design phase, technologies like computer-aided design (CAD) and virtual reality (VR) are commonly used to create and refine product prototypes.

Question 18

A model base management system (MBMS)performs tasks similar to a DBMS in accessing,maintaining,and updating models in the model base.

Accepted Answer

A model base management system (MBMS) is designed to manage a collection of models, which may be used for a variety of purposes such as simulation, analysis, and design. Like a traditional database management system (DBMS), an MBMS is responsible for tasks such as accessing, maintaining, and updating the models stored in the model base. Therefore, the statement is true.

Question 19

A DSS typically provides support for only the managerial and higher organizational levels.

Accepted Answer

A DSS may support decision making at various levels of an organization, including operational, tactical, and strategic levels. While it may commonly support higher organizational levels, it can also be designed to support lower levels such as supervisors or workers making daily operational decisions.

Question 20

EIS designers should focus on simplicity when developing a user interface.

Accepted Answer

EIS (Executive Information System) designers should focus on simplicity when developing a user interface as it can enhance usability and reduce the learning curve for the users. Simple and intuitive interfaces also reduce the risk of errors and ensure user satisfaction.
