My AOP Professor once said that today, we build software like medival smiths built swords: The customer would describe how he would want his sword to look and feel like, and the smith crafted each and every one individually. This led to very unique and well fit, but also very expensive products.
He said that we should aim to build software products like the industrialization revolutionalised manufacturing: Assembling many modular parts into something, instead of hand crafting everything. In his opinion, this will lead to faster and cheaper development.
