A typical ES should support the managers of each hierarchical level with the following capabilities.
• Drill down
• Critical success factors
• Analytics
• Exception reporting
• Navigation of information

Thereofre, the correct option is B.

Navigation of information: This capability helps executives to explore vast amount of data and information fast and easy ways. Thereofre, the correct option is B.

Critical success factors: These are the key factors that delineate the companies success levels in the market. Executives should be enabled to observe the current status of those factors including KPI’s (key performance indicators). Thereofre, the correct option is C.

Predictive analytics aims to reveal the risks and opportunities a company can face in the future. For gaining insights on the future of an enterprise, managers turn to statistical forecasting and prediction methods connected with corporate data sources. Thereofre, the correct option is A.

Descriptive analytics, sometimes called “reporting analytics” deals with the current status of the company based on the key performance indicators, i.e., KPIs. Managing a company requires appropriate monitoring the operations. Key performance indicators are chosen to summarize the business performance of the enterprise. So, they are supposed to represent what is happening in the company and indicate the potential problems. For instance, the average inventory levels, the utilization rate of the computer numerical controlled machines and robots, as well as backlogs and shortages are examples of KPIs. Thereofre, the correct option is C.

The goal of the prescriptive analytics is to provide a feasible solution or a recommendation that shows how to achieve the best performance. The methods and algorithms of some disciplines such as operations research, management science, and optimization have been widely used for prescriptive analytics. Thereofre, the correct option is E.

The most important task of a manager is to make decisions. Therefore, human decisionmaking process may be considered as a blend of the intelligence, educational background, experience, intuition, judgment, as well as personality and the cultural background of the decision maker.

What is more important than the profile of a decision maker is to follow the steps of the scientific decision making.
They are as presented by Simon:
1. Define or identify the problem or the opportunity
2. Built an appropriate representation of the problem, that is, a model
3. Search for best or better feasible solutions to the problem by using the model
4. Choose a superior solution to the problem.

Thereofre, the correct option is D

One of the fundamental concepts associated with security of information systems is known as CIA triad consists of confidentiality, integrity, and availability. Thereofre, the correct option is B.

Descriptive analytics, sometimes called “reporting analytics” deals with the current status of the company based on the key performance indicators, i.e., KPIs. Managing a company requires appropriate monitoring the operations.

The purpose of this chapter is to present the enterprise decision support systems that turn data and information of extended ERP systems into managerial and organizational intelligence.

When it comes to processing and storing information, human-beings have certain mental limits and they cannot outperform the decision support systems. The variety of the information and knowledge as pertains to the problem on hand has also a significant impact on the boundaries of the human mind. The size of the problem, the number of criteria a decision maker must consider can be faster, and the memory recall issues can be overcome almost always by EDSSs.

Phishing is one of the methods used by people with bad intentions frequently. It is a kind of action which takes benefits from peoples’ weakness.
