The best way to organize efficiency in your business is by taking a step back and defining the problem.  This is precisely what is taught in the wildly popular and successful program, six sigma.  Six sigma teaches companies to take a hard look at their processes.  They want you to define your process, try it out, analyze for mistakes, and then execute the plan.  The great thing about six sigma, is that it always brings the process back to the program, identifying how you were able to make the program better by being a part of six sigma.  It is perfect for almost all companies.
