This paper (16 page PDF) documents the use of a Learning Engineering Evidence and Decision (LEED) tracker to answer three questions. To paraphrase: How do practitioners track and cite sources of influence on design decisions? Requirements and Experience. How do practitioners communicate, revisit, and iterate these decisions? Stakeholder requirements and technical changes. When revisions were made to decisions, what sources of influences led to these changes? Changes to requirements, and experience. I think the study was worth conducting, but the overall pattern that emerges for me is that there isn't much recording of the basis for decisions other than the requirements document. "The exclusive concentration of decisions that cite Requirements: SME across CIF projects... reflects the strong presence of an instructor (SME) throughout the projects and how this influence was top of mind for LDPs when designing."
