Plans for next phase

• Detailed Design & Component Selection
• Design and describe the completed product of the components found in our Environmental Test Chamber
• Determine High, Medium and Low risk area in our detailed design
• Improve our Bill of Materials and narrow down our budget, to discuss with our customer the investment needed in completing the project
• Review our risk assessments, and design a chart of mitigation options
• Review our design output to confirm that the subsystems address all requirements
• Feasibility Analysis. Finishing touches on our CAD simulation, and prototyping
• Follow up with our advisor who can critically review our design elements to confirm feasibility.
