Articulated within this paper is a qualitative investigation into using structuration and semiotic theories that suggests improvements to communication when developing new software. Forming the analysis, an Information System (IS) designed using the Unified Modelling Language (UML) allied with the Agile software development process exposed a key factor: the need for effective communication. This factor caused a negative outcome when developing a new IS necessary to support the digitalisation of a business. Analysing the conditions and adjusting requirements modelling with structuration and semiotic theories, team members expressed with clarity requirements for their new IS as real-world effects and causes. Such cause and effect statements align to Peircean interpretant signs that facilitated effective communication.
