There is a wide area of applications that use embedded systems, and the number of such systems keeps growing. The\r\nrequired functionality and complexity of embedded systems are also constantly increasing, and development of such\r\nproducts is becoming increasingly harder. This requires new thinking on the product development processes, and\r\none such emerging philosophy is the agile methods. These methods were created by the software engineering\r\ncommunity where they are commonly used. Since then, they have been adopted in embedded systems\r\ndevelopment; however, whether they can improve the embedded systems product development processes remains\r\nan open question. This study aims to bring forth what is known about agile methods in embedded systems\r\ndevelopment and to find out if agile practices are suitable in this domain and what evidence is there to support the\r\nfindings. We conducted a literature review and a mapping study to answer these questions. The scope of this study is\r\nnot only limited to embedded software development, but also to embedded hardware and integrated circuits. We\r\nhave found that agile methods can be used in the embedded domain, but the methods and practices need to be\r\nadapted to suit the more constrained field of embedded product development. Furthermore, the field of embedded\r\nproduct development has wide diversity of products with different needs and domain-specific problems so that no\r\nsingle method is applicable, but rather many methods and practices are needed for different situations.
