This paper presents the Geotechnical Workbench software that was developed by a working team in BHP Iron Ore with the intention of providing an integrated tool to the geotechnical team that permits consistent decision-making of strength properties for slope design. This paper includes a description of the steps taken for software development and the list of learnings gained by the working team. This information is shared for the wider industry for the benefit of others that may endeavour a similar initiative. The software architecture is presented in a very minimalistic manner to protect intellectual property, however, the paper still shows the general idea of software functionalities including some description for the major tools developed within the whole package.

Keywords: software, decision-making, slope design
