PEST analysis stands for "Political, Economic, Social, and Technological analysis" and describes a framework of macroenvironmental factors used in environmental scanning. It is also referred to as the STEP, STEEP or PESTEL analysis (Political, Economic, Socio-cultural, Technological, Legal, Environmental). Recently it was even further extended to STEEPLED, including ethics and demographics.

The Porter 5 forces analysis is a framework for business management developed by Michael Porter in 1979. It uses concepts developed in Industrial Organization (IO) economics to derive 5 forces that determine the attractiveness of a market. It is also known as FFF (Fullerton's Five Forces). Porter referred to these forces as the microenvironment, to contrast it with the more general term macroenvironment. They consist of those forces close to a company that affect its ability to serve its customers and make a profit. A change in any of the forces normally requires a company to re-assess the marketplace.

The Boston Consulting Group (BCG) is a management consulting firm founded by Harvard Business School alum Bruce Henderson in 1963. He left HBS ninety days before graduation to work for Westinghouse, where he became one of the youngest vice presidents in the company's history. He would leave Westinghouse to head Arthur D. Little's management services unit before accepting the challenge from the CEO of the Boston Safe Deposit and Trust Company to start a consulting arm for the bank.
In 1965 Henderson thought that to survive, much less grow, in a competitive landscape occupied by hundreds of larger and better-known consulting firms, a distinctive identity was needed, and pioneered "Business Strategy" as a special area of expertise for BCG.

The growth-share matrix chart.
In the 1970s, the BCG created and popularized the "growth-share matrix", a simple chart to assist large corporations in deciding how to allocate cash among their business units. The corporation would categorize its business units as "Stars", "Cash Cows", "Question Marks", and "Dogs", and then allocate cash accordingly, moving money from cash cows toward "stars" and "question marks" that had higher market growth rates, and hence higher upside potential.
The chart was popular for two decades and "continues to be used as a primer in the principles of portfolio management," as BCG says.

PEST

http://en.wikipedia.org/wiki/PEST


PEST analysis stands for "Political, Economic, Social, and Technological analysis" and describes a framework of macroenvironmental factors used in environmental scanning. It is also referred to as the STEP, STEEP or PESTLE analysis (Political, Economic, Socio-cultural, Technological, Legal, Environmental). Recently it was even further extended to STEEPLED, including ethics and demographics.

It is a part of the external analysis when doing market research and gives a certain overview of the different macroenvironmental factors that the company has to take into consideration. Political factors include areas such as tax policy, employment laws, environmental regulations, trade restrictions and tariffs and political stability. The economic factors are the economic growth, interest rates, exchange rates and inflation rate. Social factors often look at the cultural aspects and include health consciousness, population growth rate, age distribution, career attitudes and emphasis on safety. The technological factors also include ecological and environmental aspects and can determine the barriers to entry, minimum efficient production level and influence outsourcing decisions. It looks at elements such as R&D activity, automation, technology incentives and the rate of technological change.

The PEST factors combined with external microenvironmental factors can be classified as opportunities and threats in a SWOT analysis.
