is characterised by repeated, varied attempts which are continued until success,[2] or until the agent stops trying. iterative design example According to W.H. Thorpe, the term was devised by C. Lloyd Morgan after trying out similar phrases "trial and failure" and "trial and practice".[3] Under Morgan's Canon, trial and error method of learning animal behaviour should be explained in the simplest possible way. Where behaviour seems to imply higher mental processes, it might be explained by trial-and-error learning. An example is the skillful way in which his terrier Tony opened the garden gate, easily misunderstood as an insightful act by someone seeing the final behaviour. Lloyd Morgan, however, had

watched and recorded the series of approximations by which the dog had gradually learned the response, and could demonstrate that no insight was required to explain it. Edward Thorndike showed how to manage a trial-and-error experiment in the laboratory. In his famous experiment, a cat was placed in a series of puzzle boxes in order to study the law of effect in learning.[4] He plotted learning curves which recorded the timing for each trial. Thorndike's key observation was that learning was promoted by positive results, which was later refined and extended by B.F. Skinner's operant conditioning. Trial and error is also a heuristic method of problem solving, repair, tuning, or obtaining knowledge. In the field of computer science, the method is called generate and test. In elementary algebra, when solving equations, it is "guess and check". This approach can be seen as one of the two basic approaches to problem solving, contrasted with an approach using insight and theory. However, there are intermediate m

natural repository for iterative design. The 'Page History' facility allows tracking back to prior versions. Modifications are mostly https://en.wikipedia.org/wiki/Trial_and_error incremental, and leave substantial parts of the text unchanged. Common law - The principle of legal precedent builds on past experience. This makes law a form of iterative design where there should be a clear audit trail http://www.instructionaldesign.org/models/iterative_design.html of the development of legal thought. Evolution - There is a parallel between iterative and the theory of Natural Selection. Both involve a trial and error process in which the most suitable design advances to the next generation, while less suitable designs perish by the wayside. Subsequent versions of a product should also get progressively better as its producers learn what works and what doesn't in a process of refinement and continuous improvement. There are several instructional design models based on the principle of iterative design: Rapid Prototyping Spiral Model Instructional Design Jobs Instructional Design Books © 2013 Richard Culatta | Multiple domain web hosting provided by InnovativeLearning.com

Answer like yes or no won't be much useful. –Rachel Sep 23 '09 at 16:48 1 Short answer: who cares if it is homework? –BryanH Sep 23 '09 at 16:49 1 @BryanH - read the FAQ on asking homework questions: meta.stackexchange.com/questions/10811/… –womp Sep 23 '09 at 17:03 | show 5 more comments 7 Answers 7 active oldest votes up vote 3 down vote accepted Short answer: It depends. Longer answer: Software design can be trial and error. If you are not completely sure of the software requirements, and it is something that hasn't been done that way before, it can be trial and error. But where the problem is well defined, and you are using methods that you understand, and where you have developed similar systems before, then it is more like a step-wise refinement. You have a pretty good idea of what has to be done - you build that, and during the testing process made some refinements. "Trial and Error" implies you aren't really sure if your solution will work, but you will give it a shot, on the understanding that if it doesn't work, you scrap it and try again, hopi

SIGN UPGLOSSARYIterative DevelopmentWhat is Agile?Agile Manifesto12 PrinciplesSubway Map to Agile PracticesAgile GlossaryPractices TimelineDefinitionAgile projects are iterative insofar as they intentionally allow for "repeating" software development activities, and for potentially "revisiting" the same work products (the phrase "planned rework" is sometimes used; refactoring is a good example).They are iterative in a third, less essential sense, in being most often structured around a series of iterations of fixed calendar length. However, some Agile approaches to scheduling, such as Kanban do away with iterations in this later sense, but retain the other aspects of multiple repetitions and planned rework.Nearly all Agile projects are incremental as well as iterative. However, it is possible to use iterative strategies which are not also incremental; for instance, a "b
