1.effectiveness

Effectiveness means the capability of producing an effect.

In mathematics, effective is sometimes used as a synonym of algorithmically computable.

In physics, an effective theory is, similar to a phenomenological theory, a framework intended to explain certain (observed) effects without the claim that the theory correctly models the underlying (unobserved) processes. An example is an effective field theory that "pretends" that certain effects are caused by a field even if it is known that this is not actually the case. In a way, any theory of Physics is fundamentally an effective theory, since there is no meaningful distinction of observables and reality within the scope of Physics (see also FAPP, cogito ergo sum, Phenomenalism, Pragmatism).

efficiency is a term used in the comparison of various statistical procedures and, in particular, it refers to a measure of the desirability of an estimator or of an experimental design.^[1] The relative efficiency of two procedures is the ratio their efficiencies, although often this term is used where the comparison is made between a given procedure and a notional "best possible" procedure. The efficiencies and the relative efficiency of two procedures theoretically depend on the sample size available for the given procedure, but it is often possible to use the asymptotic relative efficiency (defined as the limit of the relative efficiencies as the sample size grows) as the principal comparison measure.

Efficiencies are often defined using the variance or mean square error as the measure of desirability.^[2] However, for comparing significance tests, a meaningful measure can be defined based on the sample size required for the test to achieve a given.

Productivity is a measure of output from a production process, per unit of input. For example, labor productivity is typically measured as a ratio of output per labor-hour, an input. Productivity may be conceived of as a metric of the technical or engineering efficiency of production. As such, the emphasis is on quantitative metrics of input, and sometimes output. Productivity is distinct from metrics of allocative efficiency, which take into account both the monetary value (price) of what is produced and the cost of inputs used, and also distinct from metrics of profitability, which address the difference between the revenues obtained from output and the expense associated with consumption of inputs.

1.Explain why strategy and strategic moves important to business?
strategy is a plan of action designed to achieve a particular goal. The word strategy has military connotations, because it derives from the Greek word for general.^[1]

Strategy is different from tactics. In military terms, tactics is concerned with the conduct of an engagement while strategy is concerned with how different engagements are linked. In other words, how a battle is fought is a matter of tactics: the terms that it is fought on and whether it should be fought at all is a matter of strategy.

trategic planning is an organization's process of defining its strategy, or direction, and making decisions on allocating its resources to pursue this strategy, including its capital and people. Various business analysis techniques can be used in strategic planning, including SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats ) and PEST analysis (Political, Economic, Social, and Technological analysis) or STEER analysis (Socio-cultural, Technological, Economic, Ecological, and Regulatory factors) and EPISTEL (Environment, Political, Informatic, Social, Technological, Economic and Legal).

formation technology provides a platform for a company to connect the global world with Internet. Internet has a wide range of customers, buyers, service providers, technical staff, etc. with the help of Internet business can run on a single website like General Electric company in our book case study at page no 5

Information system and technology provide various channels to communication like E-mail, Instant messages, SMS servers, etc to all employees at any time all over the world. This type of software helps to saving time and cost. Of the company

3. identify the basic initiatives gaining a competitive advantage?

Present economic challenges aside, there is another crisis looming in the business sector that may not be as easily seen. And may, to some, seem secondary given the current focus on basic survival: the long-term sustainability of a business as the retiring baby-boomer generation leaves an increasingly

1. Why information are essential to business?

It helps company to gain a competitive advantage. Information system such as M.I.S refers broadly to a computer based.

2.Data vs Information.
Generally, data mining (sometimes called data or knowledge discovery) is the process of analyzing data from different perspectives and summarizing it into useful information - information that can be used to increase revenue, cuts costs, or both. Data mining software is one of a number of analytical tools for analyzing data. It allows users to analyze data from many different dimensions or angles, categorize it, and summarize the relationships identified. Technically, data mining is the process of finding correlations or patterns among dozens of fields in large relational databases.

3. What is a system?

• instrumentality that combines interrelated interacting artifacts designed to work as a coherent entity; "he bought a new stereo system,
  

a group of independent but interrelated elements comprising a unified whole; "a vast system of production and distribution and consumption keep the country going"
