At the start of the course, the class worked together on defining a problem we were going to solve as competing teams\u2014the outcome of which would be a major chunk of our grade. Being seniors we wanted to keep the problem simple and the brainstorming session came down to \u201c<em>a paper airplane that went the farthest would be the winner\u201d<\/em>. The professor guided us by pointing out a few problems with our requirement:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Paper? Why not some other material? That discussion lead to removing the paper and substituting an \u2018object\u2019<\/li><li>Went the farthest? What would you use to launch this airplane\/object in a consistent way? After a long discussion, it was decided we would need a standard launch platform that could consistently launch each airplane\/object. A 10-foot step ladder with a shelf at the top rung was acquired from the nearest custodial closet and the top rung shelf when dropped would be the standard launch platform.<\/li><\/ul>\n\n\n\n<p>\u2026so the requirement was adjusted to be \u201can object dropped [with no assist] from the [standard] 10 foot step ladder shelf [Brand X Model Z serial # 332207] that went the farthest [the point at which the object stops] as measured by tape measure [Brand Q model D; stored at room temperature (70\u2019 F) prior to measurement [as documented by periodic temperature measurements performed by a disinterested, outside the class student\u2014background-checked<em> for conflicts of interest] would be the winner\u201d<\/em>.&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Design<\/h3>\n\n\n\n<p>After all those arguments\/discussions, the professor divided us into teams and the competition began with the \u2018fly off\u2019 taking place on the last day of class. It wasn\u2019t long before there began to be scheduling conflicts for the launch platform and wind tunnel with a scheduling system put in place for using the test equipment (including accusations about some teams overscheduling the equipment and subletting their time for a price and rumors about industrial espionage).&nbsp;<\/p>\n\n\n\n<p>As designs evolved, questions arose about the environment within which the airplane\/objects would be finally tested\u2026 outside weather, wind, etc. Arrangements were made and the requirement adjusted (and approved by the configuration control board staffed by representatives from each team) to designate the college basketball arena as the environment within which the final fly-off contest would take place.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/14\/2019\/12\/Integrated-Requirements-1024x716.jpg\" alt=\"Integrated Requirements\" class=\"wp-image-4023\" width=\"390\" height=\"272\" srcset=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/14\/2019\/12\/Integrated-Requirements-1024x716.jpg 1024w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/14\/2019\/12\/Integrated-Requirements-600x420.jpg 600w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/14\/2019\/12\/Integrated-Requirements-768x537.jpg 768w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/14\/2019\/12\/Integrated-Requirements-1110x776.jpg 1110w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/14\/2019\/12\/Integrated-Requirements.jpg 1200w\" sizes=\"auto, (max-width: 390px) 100vw, 390px\" \/><\/figure><\/div>\n\n\n\n<p>On the last day of class, the certified ladder\/launch platform as placed on the center court to provide adequate space 360 degrees around the launch platform for those airplanes\/objects that might turn during flight (it was agreed by the Requirement CCB to adjust the definition of distance to convey the absolute distance from the launch platform; not just \u2018in front\u2019 of the launch platform).&nbsp;<\/p>\n\n\n\n<p>A random drawing was held (using the vetted disinterested outside class student) for the sequence of the launch trials. Each team launched their airplane\/object which included a number of elegant airplane-like solutions (carbon fiber, Mylar skins,\u2026)&#8211;some of which went almost to the baseline from a standing start when dropped from the shelf at the top of the ladder\/launch platform. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Results with Un-Bias Thinking<\/h3>\n\n\n\n<p>Then the last team stepped forward with a SuperBall (some of you are old enough to remember the <a rel=\"noopener nofollow noreferrer\" href=\"https:\/\/en.wikipedia.org\/wiki\/Super_Ball\" target=\"_blank\">Wham-O SuperBall<\/a>). The entire class appealed\/demanded an evaluation of the SuperBall solution by the professor;  &#8220;an object when dropped from\u2026&#8221; \u2026a SuperBall met the requirements. The SuperBall team had also been testing their solution with the standard test equipment\/launch platform and figured out how to place their solution on the shelf that when dropped it would consistently hit the bottom rung of the test equipment\/ladder and it took off out of the basketball court and down an exit hall on the way out of the arena, blowing away the competition and getting the &#8220;A&#8221; in the contest.<\/p>\n\n\n\n<p>The losers all learned a valuable lesson about preselection bias\/error that day.<\/p>\n\n\n\n<p>Preselection bias (our airplane thinking) had blinded us to other possible solutions to the requirements.
