Lecture 3: Practicality Why Easier to build. Verifiable. Test at every step Good interfacing. Systems Engineer Innovation Small steps within practical structure Big dreams: Break into pieces, do each simply, fit them together Lots of untried pieces means more points of failure and confusion Make everything old and tested and working, then add or modify one at a time Dreamers come up with the vision. Engineers make it practical. Be both! Activity: Take something old and improve it one step at a time. Example: Buildings (even new and innovative ones) are made of the same old steel and concrete. 'Green' buildings change one single aspect at a time (recycled materials, rooftop garden, improved airflow, reflective windows) _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ Main Project: Is your project practical? How do you make it so? Find ways to use common materials and components to come up with an initial design (demo, model, or rough prototype) _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________
