The key to Lean is minimizing waste. Create current value stream maps to see how things operate now and find where the wasted time comes from (waiting, overproduction, rework, movement, people, intellect, inventory and transport). This will give you a better idea of where the poor quality comes from.
An example is waste in movement. For me it came when I performed a 5S analysis on my vehicle. Once I found that I was wasting time making multiple trips too and from, digging for tools and parts and just being disorganized, I was able to improve the quality of the work I was doing because things were easier to find and get too. Plus, everything was is a specific place and returned there for the next time.
Follow these and you may find how to overcome your road block.
