Current and necessary insights into SACM: An analysis based on past publications

SACM (Structured Assurance Case Metamodel) is a standard for assurance case creation and exchange. Although it is a promising initiative towards providing common system assurance practices and improving them, the document of the standard provides little information about how to use SACM, its benefits, and its limitations. Consequently, it is difficult to determine what SACM can be used for and what needs to be investigated about the standard. This position paper aims to address this issue by reviewing 28 publications that have referred to SACM. Based on the insights gained, we propose a set of aspects that need to be further studied. This information can be valuable for anyone interested in the standard.
