In the course of Management System audits, auditors often find themselves confronted with various LEAN implementations and as a result, trepidation sets in as to the validity of these tool implementations of solid, ‘moving forward’ continual improvement examples (ref. AS9100C, 8.5.1).
It’s interesting to see examples of how LEAN can overcome an organization and peel away at foundational layers of a Management System but in the end, I contend the most effective organizations have LEAN and Management Systems ‘working together’. Imagine for a moment a LEAN implementation without … robust data analysis (ref. AS9100C, 8.4), standardized work instructions (ref. AS9100C, 4.2.3 and 4.2.4), process identification (ref. AS9100C, 4.1 and 8.2.3) and even ‘just fix it’ tools (ref. AS9100C, 8.5.2). It’s hard to imagine, isn’t it? Nonetheless, auditors come across this all the time and we sit there dazed and confused.
Clearly a company that is elevated a LEAN culture within their organization would NOT handle these overlapping tool sets independently and one of the important aspects of a robust internal audit program (ref. AS9100C, 8.2.2) over time is that we look for evidence of how processes are stabilized and requirements are formalized (using a process-approach, appropriate process audit trails). In the end, without this settling with continual improvement and the formalization of tools within a comprehensive Management System, LEAN will need to keep LEAN’ing back in.
