Problem solving and design
analyzing pre-release material

Top-down design

• Breaking down the system into smaller modules
• If necessary, modules can further divide into smaller sub-modules until each one is simple enough (maybe performing single action)
• We often use structure diagrams to represents this design process (textbook p.116)

Work in group of 3, analyze the pre-release material and produce a detailed structure diagram. 

Give 2 minutes presentation explains why you design your diagram in this way.
