Lesson: Date: Words: Michael Porter Five Forces Analysis Michael Porter’s Five forces framework as explained by Kotler and Keller (2011) as well as Proctor (2000‚ pg. 103) is an analysis method that involves analyzing a specific sector from five various perspectives in order to establish the nature of competition in the given sector. The five different forces in the framework consists of bargaining power of buyers‚ competitor rivalry‚

BASE ISOLATED BUILDINGS What is base isolation? When a building is built away (isolated) from the ground‚ resting on flexible bearings or pads known as base isolators. It is of the most popular means of protecting a structure against earthquake forces. HISTORY The first evidence of architects using the principle of base isolation for earthquake protection was discovered in Pasargadae. One of the world’s first base-isolated structures – the William Clayton building Base Isolation

Competitive Forces (Porter’s 5 Forces) Analysis of the competitive environment can be done utilising Michael Porter’s 5-forces model of UPS and FedEx. Porter’s theoretical framework allows us to determine the overall profitability and sustainability within the industry (Laudon & Laudon 2006‚ pg.99; Hubbard 2004‚ pg.211). We reckon that in this case‚ the competitive forces for both UPS and FedEx are very similar because they are both in the same industry. Power of substitutes: Communications

Types of Forces Used in Basketball Forces are found everywhere‚ but of course‚ you can`t see them. They act on you for example if you are waking there are many forces that act`s on you. If they are not involved you can`t wake. Let`s talk about the forces that are involved in basketball. Basketball is a very enthusiastic sport and you must try it‚ you are not going to regrets. Basketball has original thirteen rules‚ but I am just going to mention 10 of them. 1- The ball can be thrown in any direction
