  2. Agenda • Recap: Background Info. & Requirements • System Analysis • Functional Decomposition • Concept Analysis • Concept Selection • System Architecture • Engineering Analysis • Risk Assessment • Test Plan • Next Steps

  3. Background Information & Requirements

  4. Problem Statement Current State: • In order to use the Better Water Maker (BWM) users must first pour the water through a cloth before being treated. Desired State: • The device should clear particles from water to allow the BWM to operate more effectively. • The device should be simple to use and operable by both women and children. Project Goals: • Analyze the design selected by P13418 • Improve the effectiveness of the Better Water Maker Notable Constraints: • Must be usable by both women and children • Only locally available materials may be consumed • Must not negatively impact the smell and taste of water
