Preliminary Design Review

2. The Design Process Review
Design is an iterative process where the engineer must analyze the design (i.e., break apart, deconstruct), identify areas of greatest uncertainty, study (rapid prototype) possible solutions, and along the way eliminate poor or unsuitable solutions.
Once the parts of a design are understood, the design can be synthesized (i.e., put back together, reconstructed) and the design studied as a whole (i.e., at the system level).
Over the entire design process (analysis and synthesis) the criteria for making decisions are the mission objectives and requirements.

3. Preliminary Design Review
The Preliminary Design proceeds from a clear definition of the
Mission Objective(s) and Profile
Program/Project Level 1 Requirements/Verification
System/Subsystem Level 2 Requirements/Verification
This documentation was codified in the Project Plan
The Preliminary Design Review presents how your design has proceeded to date with the goal of meeting these objectives and requirements.

4. Preliminary Design Review Guidelines
Power Point Presentation
20 minute maximum duration
Each person in the group should present their own work.
Be familiar with the material, do not reed it from the overhead or from a sheet of paper
Speak clearly, with authority, and eloquently
Practice the presentation to ensure all topics are covered in the time allotted.
Have simple and uncluttered visual materials.
Do not put too much information on one visual.
Plagiarism – Provide source for all visuals, text, block diagrams, etc.

7. Clearly state Mission Objectives and Mission Profile

8. Level 1& 2 Requirements Requirement Evaluation Rubric
Is the requirement, Quantitative, Verifiable, and Realizable
Is the requirement located at the correct level (1 – Program/Project or 2 – System/Subsystem)
Is the requirement response to a higher level requirement or customer’s objective? Is the linkage clearly defined? Is requirement consistent with other requirements?
Does requirement provide links to source material?
Are equations used to calculate a requirement provided and are answers correct?
Is language in the form of a requirement?
Is a single requirement defined (i.e., breakup statements that contain multiple requirements)

9. Level 1& 2 Requirements Presentation Options
Level 1and Level 2 requirements with verification on separate slides.
Level 1with drilled down Level 2 on same slide with verification on separate slides.

13. Interface Definition Design examples
Your system interface definitions can take many forms including schematic(s) and tables.

14. Resource Reports
Resources that are important to your project need to be tracked over the life of the project.
UFO Ab-ducted, BiPed, Spider, – Power and Mass
Rover, ATechTop – Power
Cost must be managed by all projects
Over the life of the project; as simulations and experiments are run, trade-off studies completed, models and prototypes built and tested, you will be able to finalize your design. Until then, there will always be uncertainty. This level of uncertainty is managed by allocating margins to project resources. This may be done at the system, subsystem, and/or component level.
