• Asses the risks involved in completing a story and also provide the back - up plan if a story cannot be done because of external dependencies or due to any technical difficulties, so that the Product Owner can scope that item for upcoming release just in case if that cannot be done in the current release.
• Prepare a design document after analyzing the requirents by converting those requirements into technical implementation.
• Participate in design review meeting with Architect, Team lead and any other developers, and review the design approach that was choosen. Give the reasoning why this implementation was chosen.
