Because of turbulent\nbusiness environments, organizations pursuing operational excellence are faced\nwith constant change. This creates a pressure to change the IT within. Thus, the\nburden of changing business requirements is forwarded into organizations de-\nveloping the IT systems. The constant change expresses that software systems\ntend to be evolutionary in their nature. Software evolution is a theoretical lens\nwhich explains the aspects faced by software development organizations when\ntrying to handle the constant evolution. To cope with the encumbrance of soft-\nware evolution, software organizations are continuously searching for more\neffective manners to operate. This was, for example, realized in the early 2000s\nas the emergence and popularity of agile development methodologies. A more\nnovel trend in systems development is an operational model called DevOps.\nDevOps has a promise of streamlining and speeding up the development, re-\nlease and operation of software systems. However, science and the software\nindustry are far behind in understanding the influence that DevOps has on\nsoftware evolution.\n\nThe aim of this research is to investigate the impacts of DevOps in manag-\ning software evolution. The paper includes two sections. The first section is a\nliterature review of software evolution and DevOps. The section reveals aspects\nand importance of software evolution in software engineering context. Addi-\ntionally, the review recognises the purposes and practices of DevOps. The sec-\nond section of the paper introduces a qualitative study conducted by interview-\ning software professionals in three Finnish software producing companies. The\nqualitative section explains how DevOps and related practices influence the\nevolution of software systems.\n\nThe research results show that DevOps, indeed, has several significant\nimpacts in managing software evolution. Generally, these impacts are of posi-\ntive fashion. However, the findings also point out some unobvious challenges\nthat are generated into the software engineering process. DevOps is seen to aid\nthe management of software evolution in two facets.
