ABSTRACT
This chapter is adapted from my recent book Lean Auditing, published by JohnWiley & Sons (cf.
Paterson, 2015). The chapter is written for a non-audit audience and covers some key general
points about auditing, external auditing and then internal auditing, as well as more specific
insights about lean internal auditing. It also offers some wider reflections about lean ways of
working, particularly in relation to some of the cultural and behavioral challenges that need to be
recognized and managed.
