This report explores Ryanair’s domain in relation to the external environment and outlines the concerns for the company within these sectors. The environmental uncertainty of Ryanair is dealt with and ways in which it can adapt to this uncertainty are outlined. This report also explores possible strategies for minimizing environmental uncertainty for the organisation. 1.

that attempts to forecast the ultimate cost of a project. The difficulty about this analysis‚ especially for complex projects‚ is that there are a lot of uncertainties about cost items such as technology‚ productivity of human resources‚ economic conditions‚ market conditions‚ prices‚ inflation and other future risks and events. In general uncertainty occurs for a number of reasons: • Uniqueness (no similar experience) ⁎ Corresponding author at. Industrial Engineering Department‚ Bu-Ali Sina University

IB Physics Internal Assessment Andy Tang Research Question In this internal assessment‚ I am given a cantilever to find the physical properties of it. I decide to investigate the relationship between the force I act on one side of the cantilever and the maximum acceleration the tail can reach. This experiment will be also showing the elasticity of the cantilever. Since I pull down one side of it and fixed the other side‚ when I cut the string‚ it will bounce up and down until all the internal

on their own are minor problems but may have a cumulative affect. The resistance of all the wires joined together is 0.6 ohms. But the biggest uncertainty after early testing is the fluctuations on the ammeter‚ the ammeter very rarely settles on a value which leads to an inaccuracy of 0.02 volts (+/- 0.01 volts) and 0.02 amps (+/- 0.01 amps). This uncertainty could be very high especially with lower values First experiment I started with a simple experiment to get figures from which improvements could

Australian’s on the other hand generally place less importance on the need to high-end quality products. These cultural differences in approach to uncertainty and social control would necessitate awareness that Japanese employees and management may place a greater importance on procedures and protocol. Their Australian counterparts may not place the same importance on these internal procedures. If not
