I have noticed for many years now that McDonald's trains America's youth. How do they do that? By using the same procedures in every store. It doesn't matter what the location of the store is, the procedures will always be the same. At least some part of their Quality would be classified as consistency.
Years ago when all the group homes lived like families, each home had a quality statement that described their home. The girls in group home always gave a portion of their allowance to charity and supported several community endeavors. They named themselves the 'House of Giving'. All the homes had something they stood for. They developed pride of ownership, knowing something they stood for, and something to be known for.
I think we can do this in our homes today. If business can do it so can group homes. Why don't you try it in your family too? Please let me know how it works out.
