Although the philosophy behind QFD is solid -- that is to use customer inputs to create products that customers want -- the house of quality, which is the multifaceted matrix used pervasively as the tool for implementing QFD is the wrong tool for the job of innovation. Innovation is the process of finding solutions that address unmet customer needs. The house of quality emerged as a tool to ensure the product was designed as conceptualized as it went through the product development process -- not to enable the innovation process. Using the house of quality for innovation has forced QFD practitioners to execute workarounds and employ questionable practices that introduce variability into the innovation process.
Saying that QFD does not fit into the process of innovation is shortsighted. The answer is to use the Kano model and strategy to identify features that would "delight" the customer. At that point, you would include those features in the QFD process. Just like many of the tools used in Six Sigma or Lean, it's just that, a tool. You have to know how to use it within the context of the situation.

House of Qualities matrix is used by many large successful companies, of course you cant include every customer need into it but I don't understand why it is not a good tool for innovation. Direct customer inputs using "craft" production or "lean"?
