We have chosen to focus on the agile development the subject of this essay. The Agile development is a new way of thinking when working in projects. The subject for this essay includes information about the meaning, different methodologies and also a study based on the agile methodology formulation in practice. In addition to the literature the study is also based on a survey over a number of different companies in Sweden. The reason why we have chosen this topic is that throughout our three-year education we have studied the agile approach and also tried to apply all the agile methods in various projects. We have also noticed that this approach is becoming more popular to use in the business world. We have tried to explore what the agile really means, both as an agile approach itself and what it means for companies. The results obtained from our interview with companies have shown a very positive view on the agile thinking and they advocate a bright future for it. The agile manifesto which is the basic pillar of the agile thinking will guide these companies much more in the future.
