The defence industry is moving rapidly towards new types of agreement such as availability contracts based on Industrial Product-Service System (IPS2) business models. Obsolescence has become one of the main problems that will impact on a system during its life cycle. Most of the research carried out has been focused on electronic components; neglecting the impact of obsolescence in other areas such as software. This paper presents the concept of software obsolescence and highlights the key challenges and mitigation strategies to managing it; which was identified through a set of semi-structured interviews with experts in defence; aerospace and nuclear industries and literature review in software and obsolescence management. It is observed that there is a lack of understanding of the software obsolescence and the impact that it has on the systems.
