CSULB EE400D DOCUMENTATION INSTRUCTIONAL SERIES 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 material was codified in the Preliminary Design / Project Planning Blog Post. The Preliminary Design Review presents how your design has proceeded to date with the goal of meeting these objectives and requirements.

PRELIMINARY DESIGN REVIEW GUIDELINES Power Point Presentation 45 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.

TITLE PAGE Artistic Rendering of your Project This may be in the form of a drawing, 3D model, photo, or some combination. The rendering should be creative and reflect positively on your project. Team Member Names Division Assignments

PROGRAM OBJECTIVES TBD

MISSION PROFILE TBD

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) Is the requirement response to a higher level requirement or customer’s objective (Requirement Flow Down)? Is the linkage clearly defined? Does requirement provide links to source material? Does the requirement move the design process forward?

LEVEL 1& 2 REQUIREMENTS REQUIREMENT EVALUATION RUBRIC - CONTINUED Are equations used to calculate a requirement provided and are answers correct? If calculations overly complicate the slide you may simply provide a link. The requirements that are missing are the hardest to discover and will be factored into your evaluation. Is language in the form of a requirement? Avoid multiple requirements within a paragraph. (i.e., breakup statements that contain multiple requirements)

LEVEL 1 REQUIREMENTS WITH VERIFICATION What is this requirement missing?

LEVEL 2 REQUIREMENTS WITH VERIFICATION

SYSTEM 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 3DoT Projects – Power, Mass, and 3D Print Time 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. Example are TBD

PROJECT BUDGET Cost must be managed by all projects Example is TBD
