Why are we so obsessed with tools?

This is from a healthcare consultant's website....  Lean is just a bunch of tools? That's not what Toyota says... it's also a management system and a culture. Is the "tools in the toolbox" mental model holding back Lean and holding back healthcare?

The text:

Which method is best… Lean or Six Sigma?
Remember that these are tools and methods. Is a hammer better than a screwdriver or saw? Each tool is appropriate for a specific task or function. In our experience, the Lean toolbox is the place for most organizations to start. Lean is intuitive and easy for managers to put into practice. Lean methods lay the foundation for "process and flow thinking." However, most organizations find that they will rapidly need the rich statistical toolbox of Six Sigma. This is especially true when dealing with complex issues of patient flow when the obvious improvements have already been completed.

I've also never found an organization that's run out of "obvious improvements." This toolbox view can perhaps drive short-term improvement... but is that it?

This Site Says Lean is Just a Toolbox; Toyota Disagrees

A Lean Sigma website (and many others) portray Lean as "a set of tools."

Lean Sigma people often say things like "Lean and Six Sigma are just tools in the toolbox, so you choose the one you need for the problem at hand."

The problem is that calling Lean a "set of tools" diminishes the power of this management system. There's nothing in that toolbox about the core Toyota Way principle of "respect for people." There's nothing about the management system, like going to the gemba, asking why, and not blaming individuals for systemic problems.

Toyota would tend to agree that Lean is not just a set of tools, it seems, if you check out what they say:

TPS isn’t just a tool kit; it’s a culture of problem solving at every level of the organization, from top management to the workplace.

Here is how Toyota illustrates their production system as more than tools:

It's technical (tools) as well as managerial and philosophical. It's an integrated system. 

Using tools is fine, but if you're just using a tool or two from some toolbox, you shouldn't call it "Lean."
