In recent years the explosive growth of smartphones and the evolution of mobile communication networks have certainly revolutionized the way how people communicate and access information. This revolution is even more tangible in developing countries where mobile devices are becoming the preferred way to access services for their daily activities. In this context, the development of mobile applications in the areas of health, education, agriculture, and mobile banking become a crucial factor. Unfortunately, the development process presents non-trivial human and technological challenges. The goal of our research is to support people living in developing countries to improve their lives. In particular we focused our attention on assisting farmers from rural zones of Sri Lanka in optimizing their crops.

Very high adoption of mobile phones in developing countries can be used to empower people engaged in various sectors such as agriculture, fisheries and healthcare by providing timely information in right context, thus facilitating them to make informed decisions. Having identified lack of such information is badly affecting farmers in Sri Lanka we embarked on a project to develop a mobile based agriculture information system. We had to combine different theories and methods both from Requirements engineering (RE) and Human Computer Interaction (HCI) on a need basis to successfully gather the requirements. When we retraced the process we saw a definitive systematic pattern as to how RE and HCI can be used to enrich such an artefact; highlighting the strong interplay between RE and HCI. Discovery of this pattern enabled us to generalise the process
