2. Diffusion of Innovation and Best Practice

The issue… There are many things we know... lower left of Stacey... Examples: early ambulation after hip surgery, early extubation after heart surgery, aspirin after MI.... In a large organization or health system, these are done in some places well and in other places not at all. Replication of improvement is an important issue. In general, people are confused by the often failure to replicate a logically sound improvement idea. Complexity theory could provide important sense-making and strategy-aides. The question we should be seeking to answer for the leaders out there struggling with replication of improvement is: What should I do different from what I am currently doing?

Caution… There is a need for thoughtfulness in deciding what is needed in a situation. Yes, taking an area of certainty and driving it home is the problem. But also yes, creating conditions for adaptation and creativity is the problem.

Complexity Concepts: Fitness Landscapes, Coupling, Context… Kauffman's "rugged fitness landscapes" may help us understand what is happening here... In a smooth landscape, optimization of whole system is easy... On rugged landscape, optimization of whole system is hard... On smooth landscapes, all can see the optimum point and all roads lead there... On rugged landscapes, one can be trapped on a low "optimum" where any change leads to degradation and where it is hard to see that there are even higher optimum points elsewhere.

Tight coupling between practices and the context of those practices (organizational environment factors) leads to rugged landscapes. So, we need to understand how strongly coupled the "practice" is to the "context" before we simply try to replicate it. If the practice is tightly coupled to a particular context, then it will be harder to replicate into another context. Everett Rogers talks about this in his book Diffusion of Innovation. There he observes that groups often need to "rediscover" the innovation. This has the effect of breaking the coupling with the distant context and creating useful coupling to the local context. A social system that facilitates rediscovery by valuing diversity, collaboration, risk taking, etc. might be more able to accept good practices initially discovered elsewhere. (Another reference is a paper by Mark Granovetter, "The Strength of Weak Ties." Glenda Eoyang's book contains a chapter on coupling.)

For successful emergence, a complex system requires loose coupling in order to consider new ideas and tight coupling to engage them locally. Both the describer of the "best practice" and the receiver of the practice need to be conscious of this need to continuously play with coupling. (Jim Howard pointed out that Grey Elrodt did a study of diffusion of clinical pathways within VHA and found this loose-tight coupling phenomenon.)

Rogers also points out that innovation often begins in the 2% "first adopters." These folks are often not listened to in their home organizations (loose coupling). The next 10% of "adopters" are key. They are respected in their organizations (tighter coupling) but they will also listen to the odd-ball early adopters.

The idea of weak and tight coupling might also be related to the concept of legitimate and shadow organizations. Tight coupling in the legitimate and weaker coupling in the shadow. Diffusion of innovation might be easier in organizations where there is some degree of harmony among these aspects of the organization.

Plsek post … "My question is: How would you know if a practice was tightly coupled to its context? What would you be able to observe that would indicate to you that simply replicating the idea back at your place was not going to be a simple matter? (The answers to these questions could be a great contribution to the "arts" of benchmarking and rapid cycle improvement based on change concepts.)"

Levine post … I think the answer depends on a better understanding of the human relationships within the organization under review. It seems to me that process as a whole as well as the component parts of the process have differing levels of dependence on individuals. If we had a way to "measure" these individual relationships, we would have some sense of how well prepared another institution was to incorporate the benchmark institution's process.

Dooley post… Remember Shortell's important recent research re hospitals and TQM: midstream and late adopters (70% of the total) of TQM do so because they think they must in order to remain "legitimate"; the adoption process has little to do with perceived or expected benefit. Therefore, organizational readiness or context--while I admit that it *should* matter--is largely ignored by organizational decision-makers.

Complexity Concepts: Tune the CAS… Recall one of the "emerging principles of complexity:" *Tune* your place to the edge by *tuning* info flow, diversity, and so on. Tuning implies that sometimes you need more info, diversity, etc and sometimes you really do need less. Great opportunity to overlap with traditional QI approaches around the PDSA cycle of learning. Tune the info, diversity, etc *up* and reflect on what happens, tune it *down* and reflect. Continuously learning about the CAS.

Tom Petzinger's Forklift Company example illustrates the use of tuned up info flow and tuned down power differential. They made information available as opposed to saying thou shalt do it this way. Netscape is getting improvement in its browser by sharing information about its source code with a diverse and increasingly connected collection of programmers on the internet.

Complexity Concepts: Stacey Matrix… The Stacey matrix is a wonderful map for plotting issues. The questions are: Where are we on this diagram? What direction do we wish the system to go now (towards more adaptation or towards more certainty)? And what actions on my part, as a member of the CAS, are appropriate?

Don't settle down forever in the lower left of Stacey. Yes, we might be certain and agree *now* about something, but we should also from time to time purposefully pull up into the mid zone and see if some adaptation is appropriate. A useful bit of language to remind us about this is the phrase: "current best practice for the time being."

CAS theory gives us guidance on how to "play" the system on the Stacey diagram. To move toward the mid-zone: provide more information, stress divergence and diversity of thought, loosen the couplings, and so on. Vice versa to move the other direction.

A key piece of information we need for adaptation is our true position on the Stacey diagram.

Plsek post... I wish that we had a "stacey-o-meter" that we could dip into a CAS and read where it truly is. One practical way to do this would be to simply have some dialogue where everyone gets a chance to put a dot on the diagram where they think the system is on the particular issue under discussion. This would provide feedback to the system and provide a grounding for further discussion about options (maybe multiple options). Such simple reflection might have helped the Xerox situation described by Steve. Such simple reflection might keep many organizational "leaders" from wasting lots of time forcing clockware OR swarmware onto a situation when one or the other really isn't appropriate. What would our organizations be like if *everyone* in the organization understood and routinely used this one simple aide from complexity thinking?

A potentially nice demonstration project… Teach the Stacey diagram to everyone in the organization... use it for extensively for reflection... see if the organizations capacity for successful action and adaptation is improved.

Complexity Concepts: Holland's Framework… Another potentially rich set of ideas for understanding diffusion of good practice comes from John Holland's book Hidden Order. See Steve Larned 3/9/98 post for more information about how tagging, agents, internal models, aggregation, catalyzation, non-linearity, flows, and diversity might help us think through the issues around diffusion.

Thoughts About Demonstration Projects… A natural place to demonstrate new thinking based on the complexity sciences would be in the midst of current efforts around EBM, clinical paths, guidelines, etc. that people are naturally finding frustrating. This current frustration would make for a natural resonance with new thinking from complexity.

Does the current trend toward consolidation into larger organizations in healthcare make diffusion of innovation easier or harder?…

(Post from Mark Levine) Consolidation in and of itself does add to the coupling challenge. I think it is imperative to remember that consolidation causes disruption to former relationships while at the same time causing opportunity to develop new relationships. Focusing on currently existing generative relationships and actively working to maintain those relationships, it would seem to me, is the key. Encouraging a new identity and structure in the consolidated organization that fosters development of new generative relationships is the other key. (An interesting article about medical systems can be found in the Feb 15, 1998 Annals of Internal Medicine Nolan, T Understanding Medical Systems p. 293.)

Post from Al Herzog... Paul, in theory, these consolidations should make the diffusion of best practice into other organizations-from those with the best practice for `X`, much easier. In practice, this has not happened; certainly not in my system, and, as I listen to and read people like Brent James, neither in his. All of that provides some comfort, but ultimately much frustration. I think much of this has to do with trust--the level or degree of it between/among different people but there may be other, perhaps even stronger reasons. I struggle with this one but am so far without a good explanation.

Open questions...

  • Can we use complexity principles and Aides (eg. tune to the edge, coupling, fitness landscapes, shadow organizations, and so on) to build on and supplement existing thinking about diffusion of improvement?
  • Can these additional complexity-inspired approaches help us even more as we move toward consolidation and ever-larger organizations in healthcare?

Thoughts About Demonstration Projects… Need to do more thinking about this.

Ultimate Goal of This Line of Thinking… Better diffusion of improvement knowledge, evidence, best practice, and results of benchmarking studies within today's healthcare organizations. What can leaders do that is different from what they are currently doing (which is leading today to lots of frustrations)?
