Executive information system

Last updated

An executive information system (EIS), also known as an executive support system (ESS), [1] is a type of management support system that facilitates and supports senior executive information and decision-making needs. It provides easy access to internal and external information relevant to organizational goals. It is commonly considered a specialized form of decision support system (DSS). [2]

Contents

EIS emphasizes graphical displays and easy-to-use user interfaces. They offer strong reporting and drill-down capabilities. In general, EIS are enterprise-wide DSS that help top-level executives analyze, compare, and highlight trends in important variables so that they can monitor performance and identify opportunities and problems. EIS and data warehousing technologies are converging in the marketplace.

The term EIS lost popularity in favor of business intelligence (with the sub areas of reporting, analytics, and digital dashboards).

History

Traditionally, executive information systems were mainframe computer-based programs. The purpose was to package a company's data and to provide sales performance or market research statistics for decision makers, such as, marketing directors, chief executive officer, who were not necessarily well acquainted with computers. The objective was to develop computer applications that highlighted information to satisfy senior executives' needs. Typically, an EIS provides only data that supported executive level decisions, not all company data.

Today, the application of EIS is not only in typical corporate hierarchies, but also at lower corporate levels. As some client service companies adopt the latest enterprise information systems, employees can use their personal computers to get access to the company's data and identify information relevant to their decision making. This arrangement provides relevant information to upper and lower corporate levels.

Components

EIS components can typically be classified as:

Hardware

When talking about computer hardware for an EIS environment, we should focus on the hardware that meets the executive's need. The executive must be put first and the executive's needs must be defined before the hardware can be selected. The basic hardware needed for a typical EIS includes four components:

  1. Input data-entry devices. These devices allow the executive to enter, verify, and update data immediately
  2. The central processing unit (CPU), which is the most important because it controls the other computer system components
  3. Data storage files. The executive can use this part to save useful business information, and this part also helps the executive to search historical business information easily
  4. Output devices, which provide a visual or permanent record for the executive to save or read. This device refers to the visual output device such as monitor or printer

In addition, with the advent of local area networks (LAN), several EIS products for networked workstations became available. These systems require less support and less expensive computer hardware. They also increase EIS information access to more company users.

Software

Choosing the appropriate software is vital to an effective EIS.[ citation needed ] Therefore, the software components and how they integrate the data into one system are important. A typical EIS includes four software components:

  1. Text: handling software—documents are typically text-based
  2. Database: heterogeneous databases on a range of vendor-specific and open computer platforms help executives access both internal and external data
  3. Graphic base: graphics can turn volumes of text and statistics into visual information for executives. Typical graphic types are: time series charts, scatter diagrams, maps, motion graphics, sequence charts, and comparison-oriented graphs (i.e., bar charts)
  4. Model base—EIS models contain routine and special statistical, financial, and other quantitative analysis

User interface

An EIS must be efficient to retrieve relevant data for decision makers, so the user interface is very important. Several types of interfaces can be available to the EIS structure, such as scheduled reports, questions/answers, menu driven, command language, natural language, and input/output.

Telecommunication

As decentralizing is becoming a trend in companies, telecommunications plays a pivotal role in networked information systems. Transmitting data from one place to another has become crucial for establishing a reliable network. In addition, telecommunications within an EIS can accelerate the need for access to distributed data. It can be both by scientific and business means.

Applications

EIS helps executives find data according to user-defined criteria and promote information-based insight and understanding. Unlike a traditional management information system presentation, EIS can distinguish between vital and seldom-used data, and track different key critical activities for executives, both which are helpful in evaluating if the company is meeting its corporate objectives. After realizing its advantages, people have applied EIS in many areas, especially, in manufacturing, marketing, and finance areas.

Manufacturing

Manufacturing is the transformation of raw materials into finished goods for sale, or intermediate processes involving the production or finishing of semi-manufactures. It is a large branch of industry and of secondary production. Manufacturing operational control focuses on day-to-day operations, and the central idea of this process is effectiveness.

Marketing

In an organization, marketing executives' duty is managing available marketing resources to create a more effective future. For this, they need make judgments about risk and uncertainty of a project and its impact on the company in short term and long term. To assist marketing executives in making effective marketing decisions, an EIS can be applied. EIS provides sales forecasting, which can allow the market executive to compare sales forecast with past sales. EIS also offers an approach to product price, which is found in venture analysis. The market executive can evaluate pricing as related to competition along with the relationship of product quality with price charged. In summary, EIS software package enables marketing executives to manipulate the data by looking for trends, performing audits of the sales data, and calculating totals, averages, changes, variances, or ratios.

Financial analysis

Financial analysis is one of the most important steps to companies today. Executives needs to use financial ratios and cash flow analysis to estimate the trends and make capital investment decisions. An EIS integrates planning or budgeting with control of performance reporting, and it can be extremely helpful to finance executives. EIS focuses on financial performance accountability, and recognizes the importance of cost standards and flexible budgeting in developing the quality of information provided for all executive levels.

Advantages and disadvantages

Advantages of ESS

Disadvantages of ESS

This trend frees executives from learning different computer operating systems, and substantially decreases implementation costs. Because this trend includes using existing software applications, executives don't need to learn a new or special language for the EIS package.

Interactive visualizations are trending. 3D visualizations in a VR/AR environment looks like a possibility already. Also, predictive analytics open the doors for (machine) learning what is going to be next based on data from the past. While the data processing can be done in many ways, learning is not completely unsupervised. There is still a good deal of classification using expert personnel analysis. In near realtime scenarios, latencies while doing ML can be a barrier. Optimizing data models, size and processing path/time are ongoing work. As more data is captured at different data stages in not only EIS apps but also other enterprise apps, audio and video tagging can catalyse data discovery.

A computer appliance is a computer system with a combination of hardware, software, or firmware that is specifically designed to provide a particular computing resource. Such devices became known as appliances because of the similarity in role or management to a home appliance, which are generally closed and sealed, and are not serviceable by the user or owner. The hardware and software are delivered as an integrated product and may even be pre-configured before delivery to a customer, to provide a turn-key solution for a particular application. Unlike general purpose computers, appliances are generally not designed to allow the customers to change the software and the underlying operating system, or to flexibly reconfigure the hardware.

A marketing information system (MIS) is a management information system (MIS) designed to support marketing decision making. Jobber (2007) defines it as a "system in which marketing data is formally gathered, stored, analysed and distributed to managers in accordance with their informational needs on a regular basis." In addition, the online business dictionary defines Marketing Information System (MKIS) as "a system that analyzes and assesses marketing information, gathered continuously from sources inside and outside an organization or a store." Furthermore, "an overall Marketing Information System can be defined as a set structure of procedures and methods for the regular, planned collection, analysis and presentation of information for use in making marketing decisions."
