Leader Standard Work and Plausible Deniability

Truthfully, the only times I have ever heard the term "plausible deniability," other than my own frivolous use, is in movies or TV shows about clandestine operations and the like. Wikipedia says, at least for now,

Plausible deniability refers to the denial of blame in loose and informal chains of command where upper rungs quarantine the blame to the lower rungs, and the lower rungs are often inaccessible, meaning confirming responsibility for the action is nearly impossible...

Sounds spooky, no pun intended. In a lean environment there's no place for plausible deniability. It's all about transparency and the ability to identify abnormal conditions and, not to be redundant, opportunities.

Leader standard work is SDCA (standardize-do-check-act) in action. It seeks to determine whether standards are being adhered to and whether they are sufficient - very important stuff when you are to trying to sustain lean gains and develop a lean culture.

We all know that good leader standard work is supplemented by good visual controls - ones that enable "drive by" ease to determine normal versus abnormal. What some folks unfortunately don't comprehend or want to comprehend is that leader standard work is redundant or "nested."

A supervisor or team leader's leader standard work may represent as much as 50% of their time on the job. A next level manager 30%. A value stream leader (i.e., plant manager) as much as 20% or so. Is each level's standard work totally different? No! There's redundancy. The frequency and scope may differ, but the checker, and the checker of the checker (and so on) is being checked at multiple levels.

This may sound like muda. But, in lean we often rely upon "human systems." Human systems are fragile in nature and therefore need rigorous support and maintenance. This rigor requires direct confirmation. Are you more inclined to properly execute your assigned tasks if you know that someone is going to be auditing your work and your area of responsibility - in person?

Indeed, while leader standard work must include the superior checking the subordinate's leader standard work document to, among other things,: 1) ensure that it has been completed in a timely manner, 2) identify what abnormalities have been identified (and whether they are of a repeat variety), and 3) the sufficiency of the subordinate's countermeasures, it also must include direct observation. We, like Taiichi Ohno, must prefer facts over data.

The superior's leader standard work must also require him or her to go to the gemba and for example, ensure that the operator(s) is working in accordance with standard work - steps, sequence, cycle time, and standard work-in-process. Anything less than that and we're in the plausible deniability realm, taking the "word" of the second hand information and never verifying...even though we may have more than an inkling that the system is breaking down. "Hey, my subordinate was checking that in their leader standard work..."

It's not that we shouldn't trust people, we just need to be good lean pragmatists. We need to model the proper behaviors and actively lead and coach. Good leader standard work, and thus SDCA, does not co-exist with loose and informal chains (of command). Nothing deniable there.

Hi Bill,

Thanks for the comment! My viewpoint is based upon years of direct observation of others and my own successes and failures as a lean leader.

Best regards,
Mark

I take this a step further - everyone's standard work should be posted in a common area. How do I know what my boss is focused on? Most people rely on piecing together random inquiries to determine the pattern of focus, often over-reacting to the results. But if I see their focus, their full focus, in their standard work, then I truly know. That's transparency.

Jamie,

Exactly! Everyone's standard work should be posted, typically at their work station. This includes leader standard work. After the leader completes their leader standard work, I typically prefer that it is posted (with a visual control that gives insight as to whether or not it has been completed on time) adjacent to the appropriate tiered performance metric board, etc.

I coach folks, as they are in the process of developing and deploying their leader standard work, to show their folks the leader standard work - from an audit standpoint, what they're looking at and why. From a task standpoint, that should be transparent as well.

Best regards,
Mark
