Here’s the mantra;

Keep it Lean, Keep it Simple, Keep it Real, Keep it Going

Here’s what I mean:

• Keep it lean
  Generally, dysfunctional or under-performing factories are operating
  inefficiently, and lots of low-hanging fruit can be gathered and hauled
  away by utilizing lean principals.
• Keep it simple
  Identify concrete problems and propose limited but effective solutions.
  If you are responsible for leading a turn-around, the complexities of
  perfectionism are simply not part of your world! Go for a quick fix for
  80% of the problem and go snag the remaining 20% later after you’ve
  become a hero.

• Keep it real
  Make sure you accurately measure progress (inventory reduction,
  operating cost reduction, on-time delivery, production cycle time,
  etc.) against accurate baseline data. If a performance indicator is
  really difficult to measure, it may need to be changed to one which can be measured easily.  (e.g., SMART KPI)
• Keep it going!
  Ensure that your performance is repeatable by establishing
  transformational best practices as written procedures, on which all
  relevant personnel are trained.
