Industries like marketing, sales, and other domains that are not specific to software borrowed Agile principles and proved that these methodologies could be applied widely.<\/p>\n\t<p>Agile approach allows more adaptive and evolutionary processes, helping companies to respond to rapid market and technology shifts.<\/p>\n\t<p>Agile has an interesting origin. Even if its start seems to be more likely in 1620 (Francis Bacon\u2019s articulation of the scientific method), this methodology was better revealed in 1986 when it was built on the model provided by Hirotaka Takeuchi and Ikujiro Nonaka (authors of \u201cThe New New Product Development Game\u201d). The concept was related to the rugby principles in a metaphorical perspective for defining the way teams work together on the field:<\/p>\n\t<p>&#8220;The &#8216;relay race&#8217; approach to product development may conflict with maximum speed and flexibility goals. Instead, a holistic or &#8216;rugby&#8217; approach \u2013 where a team tries to go the distance as a unit, passing the ball back and forth \u2013 may better serve today&#8217;s competitive requirements.&#8221;<\/p>\n\t<p>Getting back to our days, you may be wondering why Agile is the first-choice approach for software development.<\/p>\n\t<p>Let\u2019s take a quick peek at what stats say:<\/p>\n\t<figure class=\"wp-block-image\"><img decoding=\"async\" loading=\"lazy\" width=\"1403\" height=\"344\" src=\"https:\/\/www.roweb.ro\/blog\/wp-content\/uploads\/2021\/10\/loikjahdgfouyad5obro.png\" alt=\"The Agile Model\" class=\"wp-image-5789 simple-no-border\" srcset=\"https:\/\/www.roweb.ro\/blog\/wp-content\/uploads\/2021\/10\/loikjahdgfouyad5obro.png 1403w, https:\/\/www.roweb.ro\/blog\/wp-content\/uploads\/2021\/10\/loikjahdgfouyad5obro-300x74.png 300w, https:\/\/www.roweb.ro\/blog\/wp-content\/uploads\/2021\/10\/loikjahdgfouyad5obro-1024x251.png 1024w, https:\/\/www.roweb.ro\/blog\/wp-content\/uploads\/2021\/10\/loikjahdgfouyad5obro-624x153.png 624w\" sizes=\"(max-width: 1403px) 100vw, 1403px\" \/><\/figure>\n<p>&nbsp;<\/p>\n\t<h4><b>The most popular and common examples of Agile methodologies<\/b><\/h4>\n\t<ul class=\"blue-checkbox\">\n\t\t<li><b>Scrum<\/b> &#8211; a structural Agile approach based on a complex of management principles.
