Storm doors have been installed on 50%

of all homes in Any town, USA. The remaining

50% of homeowners without storm doors think they

may have a problem that a storm door could solve,

but they're not sure. Use Activities 1, 2, and 3

in the engineering design process (Table 1-1) to help

these homeowners systematically think through the

definition of their need (Activity 1), a formal statement

of their problem (Activity 2), and the generation of

alternatives (Activity 3).The design process begins in Figure P1-15 with a

statement of need and terminates with the specifications

for a means of fulfilling that need.
