risks and determine the likelihood and consequence of that risk occurring during the project. The

With the release of the new budget for year 9 from Competition Bikes, there are a couple of areas that are a concern that warrant being addressed. The first being the prediction of amount of bikes to be sold; Competition Bikes is expecting 3,510 units to be sold after a year 8 that sold only 3,400 units which was a 15% drop in sales from the year prior (which sold approximately 4,000 units) with zero drop in price point which may make it harder for customers to justify purchasing a bike in the current economy. Understandably, year 8 was in the middle of a recession and the economy could rebound for a productive year 9. However, with only an extra $984 being spent on advertisement, the expectations could fall short unless

Naval warfare had not turned out to be an especially critical factor for either the Germans or the British, and there were no truly decisive naval battles. The submarine, however, produced some earth-shaking results. Submarine warfare led to the sinking of the Lusitania, a passenger ship. This occurred during a submarine blockade of Britain. The Germans placed no limit on their campaign of submarine warfare. This campaign helped draw the United States into the conflict. Without submarine warfare, perhaps the U.S. never enters the conflict. By June of 1918, the Allied lines were so devastated that the German commander Ludendorff felt he could wire the Kaiser and state that the war might end soon. Then, U.S. troops began to arrive, as many as 250,000 a month. The Allies rallied. Germany may well have won without the infusion of U.S. troops into the battle. So, in a very unexpected way, new technology-- the deadly submarine warfare of the Germans had a decided impact on the war.

This war was the first to successfully implement many aspects of technology into warfare successfully. In fact, many technologies were invented during this war to help provide the government with a more efficient killing machine that could now ravage its enemies with considerable more ease. A great example of this improvement in killing is the introduction of the repeater rifle and the minie ball. These two technologies changed the course of war from the antiquated musket world to the at the time modern and superbly advanced repeater rifle. This rifle was able to be loaded with a cartridge that was self contained and required no packing of powder into a barrel and no tedious fuses. It could fire many rounds a minute, essentially as many as the soldier could chamber into the barrel with a charging handle on the bottom of the weapon. The antediluvian muskets were cumbersome, dangerous, inaccurate, slow to fire, as well as difficult to fire even remotely accurately. A technology that could be literally heard around the nation was the telegraph. This technology allowed generals to speak with their troops and their commander-in-chief in a fraction of the time that it would take for a messenger to ride a horse all the way from the headquarters to the front lines or wherever the message was intended to end up. As

Throughout the Progressive Era, 1890 to 1920, there was an enormous amount of change that would forever change the history of the United States of America. Ten years into this era had brought the biggest military technological innovation which was the first submarine, USS Holland Submarine. This submarine was named after its designer, John P. Holland, who was an Irish immigrant who set the foundation to the modern submarines. However, designs of having underwater boats did not start up in the 1900’s but was thought of since the 1500’s.

Weapons can change war in a matter of seconds . New military technology allows missions to be more efficient and safer. Weapons like the railgun, sonic rifle, and a self-guided bullet. Help ing by giving the advantage at the best of times. The new is coming and that means others might be advanced but behind at the same time.

The factors that made the Allied victory happen include the Germans beginning to effectively organize industrial production at the very least six months too late to give them a chance at victory. By the time they got the production to be swiftly working on weapons such as fighter planes, the Allies were in firm enough control of the air space. This meant that the Allied bombing prevented the German economy from reaching it’s full potential. Another flaw in the German production meant that tanks such as Tigers and Panthers, of which dominated tactical situations on the battlefield, had logistical and maintenance nightmares. If the Germans were to overcome their problems in production then it would have stood them in much greater stead, giving them an advantage over the Allies.

iii. The advancement in science saw the war become sophisticated as each side tried to outwit the other in tact and equipment.

McCloy para.1). The countries knew from previous wars that they needed to come up with weapons that they enemies did not have. Things like secret languages and decoding machines were brought into the war to help communicate without enemies being able to understand major issues(Robert Curley). This was not it. Advancements in tanks, planes, and most importantly machine guns were the most important of them all.

The Battle of the Atlantic was a competition between the Western (US, Britain, and Canadian navies) and the Axis Powers over control of the Atlantic sea routes.The Allies main strategy was to blockade, while the Axis Powers limited productivity and diminished morale. The Allies tried to counter the submarine attacks by traveling in convoys.They had warships that would defend them from the attacks. This method was effective for a while but Britain build more U-boats and convoying stopped working.

One of the most recognized technologic advancements in plans during world war one and two waqs the blitzberg plan. The World War Two era was a time of change. There were many technological advancements during this time. These advances can be categorized into three categories. They are weapon advances, vehicle advances, and strategic advances. This technology would change the face of war forever.

Airbus predicts that there would be demand for more than 1500 super jumbos over the next 20 years that would generate sales in excess of $350 billion. And they could sell as many as 750 over jumbos over the next 20 years with a break even on undiscounted cash flow basis with the sales of only 250 planes. There is a huge profit in this business if Airbus succeeds in the industrial launch of A3XX jumbo jets.

The B707 was the first aircraft developed by Boeing in 1958, it is a narrow body , mid-size and a four turbo-fan engine aircraft ( Pratt & Whitney ) . Some people call it ( seven oh seven ) and it has different modules ( series ) that contains different capacity from 140-189 passengers .The Boeing 787 was produced in 2007 , it is a long-range , wide-body , twin turbo-fan engine ( GEnx or Rolls Royce ) aircraft . Passenger’s seat varies from 242-335 dependant on the series of the aircraft. Of course both aircrafts varies from the internal structures ,but almost the same design for the outer structure (body shape ) , and I’ll demonstrate the differences and similarities between both aircrafts , from structure design to the innovations made to the B787 , that surely made us look at the Boeing industry in a different perspectives.

In 1943, Theodor Von Karman, in response to a request by US Air Force headquarters, claimed that the realization of a supersonic aircraft would have been doable using the right technology and tools. The fear of breaking the "sound barrier" was finally removed in 1947, when the Captain Yaeger flew the Bell X-1 at a speed slightly above Mach 1 for few seconds, producing the famous and long-awaited sonic boom (caused by an impulsive pressure change created by the sonic waves detaching from the aircraft), music for the scientists attending that historical moment, but current nightmare for the 21st Century supersonic vehicles' designers [8].
