We have all struggled with ‘Fix-it but don’t change anything’ mandates from above.  No way to win here when management is petrified of their own products, processes and customers.  There is an even more common debilitation and that is a fix-it focus.  Of course, ther...

The Roisum Library
In the last clip we lamented at the near uselessness of Google or other search engine for many web-handling and web processes needs.  We gave the example of trying to learn how to treat wrinkles by typing it into the search engine and getting offers for Botox treatments on the first umpteen pag...

Root Cause versus Outcome

Anniversary Bonus Offering

Afraid of Defects
On several occasions I have blogged about being afraid (of customers on 7/27/2009 and then again on10/16/2012 and of knobs just last week 9/11/2014).  This topic, of being afraid, deserves much more treatment because it is one of the biggest handicaps to improvement.  Just last week I ran ...
