Software
Richard Gabriel, discussing Alexander's Quality Without A Name as it pertains to software:

• It was not written to an unrealistic deadline.
  
• It modules and abstractions are not too big.
  
• Any bad parts were repaired during maintenance or are being repaired now.
  
• If I look at any small part of it, I can see what is going on.
  
• If I look at any large part in overview, I can see what is going on.
  
• It is like a fractal, in which every level of detail is as locally coherent and as well thought out as any other level.
  
• Every part of the code is transparently clear.
  
• Everything about it seems familiar.
  
• I can imagine changing it, adding some functionality.

He then asks, "Think about the quality without a name when you look at your software. Do you think your software possesses it? What would you do to make your software have it?"
