Foreword

For many years safety-critical systems domains are heavily regulated. To confirm the quality and safety of components and systems as a whole, companies working in these environments need to follow the standards that describe in detail the phases of the development life cycle and techniques to confirm the quality and safety of components and systems as a whole. Following these standards is what will make organisations successfully achieve the certification of their products. Due to the heavily regulated environment and the need to achieve successful certification, safety-critical systems companies have been doing their development by using the traditional waterfall model. Traditional waterfall model has been used to manage the development processes. While this is still in use, the creation of agile manifesto and its methods, provided an alternative to organisations looking to improve their work. The scope of the present research was to gain an understanding of whether organisations within safetycritical systems engineering can adopt the agile methodology. The objective was to identify relevant publications by conducting a literature review of articles published in Scopus and Inspec databases. The current findings show us that there is work being done in the area. Nevertheless, there is space for future work. In the conclusions, we identified some point for future work that can be followed through
