Krishna discusses avoiding pitfalls in design basis for engineering projects. Some key risks include inadequate protection, lack of accurate data, cost/schedule constraints, and lack of design expertise. Typical design basis pitfalls include unclear ownership of design documents, incomplete or changing design basis documents, and lack of communication between design and project teams. Krishna provides several case studies where failures occurred due to changes in conditions from the original design basis, such as differences in feedstock or environmental conditions. He emphasizes regularly reviewing and updating the design basis to account for new information or risks beyond the initial design specifications.
