Six Sigma In Hotel Industry

I'm interested in Six Sigma in hotels. Can anyone recommend me some books, share some knowledge?
Does anyone know, where to find an e-book Design for Six Sigma for Service (Six SIGMA Operational Methods)?

Had you searched the web, you would have found it at eBook: Design For Six Sigma For Service - PDFoo.com I have seen a hard copy about a year ago. However, it costs nearly 90 dollars.

Than you very much for reply. So, as you have seen it, could you recommend me this book? I mean, is it well written, in comparison to other publications?
Do you know other titles connected with six sigma in services? I carry out research about six sigma, so I need some scientific approach...
