Porter’s 5 Forces Analysis = Suppliers‚ Customers‚ New Entrants‚ Substitute Products‚ Competitors What is Porter’s 5 Forces Analysis? Porter’s 5 forces analysis represents the competitive environment of the firm. It is a strategic foresight to avoid putting the competitive edge at risk and ensure the profitability of products on a long term. For the company this vision is quite important because the firm is able to direct its innovations in terms of choice of strategies and investments. The

growth and decline that an industry moves through. In most examples of industry lifecycles there are either 4 or 5 phases as shown below: | | Typical 4 Phase Cycle | Typical 5 Phase Cycle | The key difference is often how the early or embryonic phases are broken down. Using the global mobile phone manufacturing industry as an example the process would best break down into 5 phases as set out below: * Embryonic (Product Development) At this point (1960’s through early 1970’s) the

systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from these equations. When applying the second condition we are free to choose any axis about which to compute torques. It is best to choose an axis that eliminates one or more forces that have lines of force that pass

INTRODUCTION Sales force management systems are information systems used in CRM marketing and management that help automate some sales and sales force management functions. They are often combined with a marketing information system‚ in which case they are often called customer relationship management (CRM) systems. Sales force management systems are essentially the same thing as sales force automation system (SFA). A SFA‚ typically a part of a company’s customer relationship management system

It would be far too expensive for a new company to copy the characteristics of Zappos including their next day delivery and large overhead. The fact that Zappos was losing money initially illustrates this difficulty. Another

framework uses concepts developed in IO economics to derive 5 forces that determine the attractiveness of a market. 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. Four forces -- the bargaining power of customers‚ the bargaining power
