Some Thoughts on Institutions

Today on Morning Edition Condoleezza Rice shared that the founders of the American republic understood institutions weren’t built for human perfections, but for human imperfections [1]. If only present day leaders understood institutions in this way, too.

We humans don’t always act in ways that help us achieve our goals. Our imperfections get in the way. So we establish ways of doing things, patterns of behavior, to help us act appropriately. This is particularly valuable during times when our judgment is clouded.

In our pursuit of ever more ambitious goals, goals that require coordinated action of many individuals, we need a system of such procedures that is designed to help us achieve those goals. When we put these procedures into practice, we collectively move toward our goals. When this pattern of behavior persists over time, we give rise to a recognizable entity: an institution.

Institutions exist to help us act in ways that make it possible to achieve the goals we set for them. They are especially valuable at times when we experience uncertainty that stokes our primal fear.

Book Review: “Systems Thinking For Social Change”

Systems Thinking For Social Change“Why are people unable to solve a chronic complex problem or achieve a meaningful goal—often despite their best efforts?” David Peter Stroh offers insight into this question in Systems Thinking for Social Change. The book is a good blend of theory and practice. In it Stroh draws a contrast between our conventional ways thinking, which seek to understand and change the world in terms of its parts, and thinking in terms of systems, which emphasizes understanding and changing the relationships between these parts.

He attempts to show the effects of these two ways of thinking with several examples pulled from current issues. Among them are homelessness, mass incarceration, and rural housing development. However, Stroh runs the risk of losing readers of a particular ideological bent when he let’s his views slip into his explanations of the examples. This even as he rightly states the requirement to engage diverse stakeholders in creating a rich understanding of a system. That would be unfortunate as Systems Thinking for Social Change has much to offer in helping people think differently so that we may come together to solve whatever problem we are confronting.

Stroh’s style is generally accessible, although it did test my focus in a couple of spots. He avoids jargon and keeps his language understandable. He methodically introduces the reader to thinking in terms of systems; on how to use this new skill to map systems and see himself and his world in a new way; on how to identify desirable and undesirable dynamics of a system, and on how to act in a way that brings about desired change. The chapters are short, made to feel even shorter with many subsections. In keeping with the systems approach of using graphics to tell stories, they contain lots of systems maps and graphs. I do wish the many maps showing causal links also included the direction of change with those links.

I think Systems Thinking for Social Change is a book you will return to repeatedly as you practice the tools it teaches. Having said that, neither Stroh nor this book will miraculously transform you into a systems thinker or reshape the way you view the world. That is something you will have to do on your own through practice. I used it to map a couple of systems at my place of work. These gave me insight into the dynamics at play. I have shown my maps to colleagues to their approval. If nothing else, we now share an awareness of what is going on. Change is not brought about through thought alone. While ideas serve to inspire, change comes about through action.

The Weekly Meeting

Monday afternoons at two-thirty. That was the time for our weekly staff meeting. When I joined the company everyone was required to attend it: engineers, technicians and operators. The head of our department, the Director of Quality, led it.

It was a rare week when the meeting started on time. Mondays were also when we had our one-on-one meetings with the Director and he had one of those exchanges going on right before our staff meeting. It always went over. So several of us would gather and wait outside of the meeting room until we were noticed and motioned to come in.

Even with this routine delay I don’t remember a single week when everyone was present before the meeting started. There was frequently at least one person who creeped in late. It wasn’t always the same person either. Some late comers might put on an apologetic face at times, but a few were shamelessly indifferent of their indiscretion.

Just as the meeting never started on time, it didn’t end on time either. I recall a few occasions when I wondered whether the meeting actually ended.

The Director got our meeting going by sharing a subset of the highlights and lowlights of the previous week that he gets in an email from the corporate overlords. We cheered the highlights and bemoaned the lowlights even though none of us could draw a connection to any them with the specific work we did. They did not prompt any actions for our department. They were also divorced from similar points shared in the previous week; presented as stand-alone bits of information. On those occasions when someone did make a tentative connection, it unleashed pent up frustrations with people feeding off of each other to blame some nonpresent “they.” So what purpose did this update serve? I couldn’t tell you.

Following the update, the Director shared his schedule for the current week. It always showed back-to-back meetings, sometimes overlapping, from the start of the workday to its end, for the whole week. So when did he have time to think and plan, to draw up an agenda for his meetings, to follow-up on assignments, to analyze, understand, and guide the performance of the system he was charged to direct? At first I had felt sympathy. What sort of monstrous organization drives its people like this? But it didn’t last long. I recognized much of it was self imposed and not a demand of the organization. It was his way of showing others how busy and engaged he was, how hard he was working, how committed he was to the company. It was all light and no heat. Perhaps I’m being harsh, but I don’t think so.

After he finished his update he would ask each staff member if they had anything to share. Most did not. Some, though, shared information on what they were doing in excruciating detail. Usually it was about “unexpected” hurdles, blocks, or breakdowns. They were the same from week to week. This was another opportunity to vent about those others who didn’t follow procedures, the unreasonable surge in demand for our services, or how the system is broken and needs fixing. Who is going to fix it? How should it be fixed? What resources are needed for the fix? That requires a plan. But when is there time and space for that?

Once a month the Director would remind everyone to calculate and report metrics they were responsible for. It shouldn’t come as a surprise that at least one was delayed. Not always the same one, but it came with all the usual excuses.

That was the ritual.

Hiring the Best and Brightest

Companies have been proudly proclaiming that they hire only the best and brightest. Ignoring the fact that this is a bogus claim – personal experience at a dozen different companies has demonstrated otherwise – a firm would find it all but impossible to function with the best and brightest.

Back in 1994 Dr Russell Ackoff shared an example that elegantly explains why.

I read in the New York Times recently that 457 different automobiles are available in the United States. Let’s buy one of each and bring them into a large garage.

Let’s then hire 200 of the best automotive engineers in the world and ask them to determine which car has the best engine. Suppose they come back and say Rolls Royce has the best engine. Make a note of it.

“Which one has the best transmission?”, we ask them and they go run tests and come back and say the Mercedes does.

“Which one has the best battery?” [They] come back and say the Buick does.

And one by one, for every part required for an automobile, they tell us which is the best one available.

Now we take that list and give it back to them and say “Remove those parts from those cars. Put them together into the best possible automobile,” because now we’ll have an automobile consisting of all the best parts.

What do we get? You don’t even get an automobile, for the obvious reason that the parts don’t fit!

The performance of the system depends on how the parts fit, not how they act taken separately.

A significant portion of organizational excellence depends on how employees interact with one another i.e. how they fit together, not how they act individually.

Dr. Ackoff’s entire talk titled “Beyond Continual Improvement” is worth listening to.
