Project for your Professional Development

• Purpose: – Get you from now in to Practice of Engineering– The greater the number of projects you have done, the

higher the confidence to tackle a difficult project

(Note: This is solely for your own development and not an obligation. However, if you do it you’ll be a better practicing engineers in the market.)

Project for your Professional Development

• Objective: Design a product from initial concept of your own choice– Name your company and specify a product that you feel its need– Develop Project Plan– Specify working principles (i.e. initial calculations and parameters required to

be given to vendor)– Indicate sketches– Design Layouts– Vendors supplying the parts along with their prices and catalogues– Detail Drawing of parts of your project (indicating material and dimension)– Assembly drawing of the project, indication section drawings if required (must

have BOM)– Also include packaging style (This will incorporate surface development topics
