Translating business intent into technology solutions is a complex cluster of cognitive activities expected from an architect. To perform valid and traceable requirements analysis, architects need to be strong in logical conclusions and critical thinking. Without strong reasoning skills, architects often revert to marketectures or leaps of faith where technical recommendations are stated without explicitly traceable logical chain. This session will show best practices in premises examination, facts validation, checking for logical fallacies and packaging/presenting the conclusions or outcomes.
