Consider the Bicycle

Now Think About Software

• Software can and should be critiqued in the same way as a bicycle:

  • Does it do what it's supposed to?

  • Is it pleasurable to use?

• What's missing is:

  • Did its design facilitate its manufacture and maintenance?

What We Need

• A vocabulary and canonical examples to ask and answer questions

• Can this be build at a reasonable cost?

• Will it hold up under constant use?

• Will people understand how to use it?

• Will they enjoy using it?

Now It's Your Turn

• I hope this book will help us get there

• Because software is beautiful—or can be

• I hope your journey won't stop here
