Value And Effectiveness

April 14, 2012 4 comments

A few weeks ago, my friend Charlie Alfred challenged me to take a break from railing against the dysfunctional behaviors that “emerge” from the vertical command and control nature of hierarchies. He suggested that I go “horizontal“. Well, I haven’t answered his challenge, but Charlie came through with this wonderful guest post on that very subject. I hope you enjoy reading Charlie’s insights on the horizontal communication gaps that appear between specialized silos as a result of corpo growth. Please stop by his blog when you get a chance.

——————————————————————————————————————————–

In “Profound Shift in Focus“, BD00 discusses the evolution of value-focused startups into cost-focused borgs.  There’s ample evidence for this, but one wonders what lies at the root?

One clue is Russell Ackoff’s writings on analysis and synthesis.  Analysis starts with a system and takes it apart, in the pursuit of understanding how it works.  Synthesis, starts with a system, identifies the systems which contain it, and studies the role of the original system within its containing systems in the pursuit of understanding why it must work that way.

Analytical thinking is the engine that powered the Industrial Revolution and many of the most important scientific advances of the 21st century.  Understanding how things work is essential to making them work better (also known as efficiency).  Today, we have better automobiles, airplanes, computers, phones, and TV’s than our parents.  And we owe much of this to analytical thinking.

But one of the side effects of analytical thinking is specialization.  As understanding deepens, the volume of subject matter knowledge explodes.  This leads to the old joke.

Q:   What’s the difference between an engineer and an executive?

A:     Every day engineers learn more and more about less and less, until one day they know everything about nothing, while executives learns less and less about more and more, until one day they know nothing about everything.

But all joking aside, this is a serious concern.  The vast majority of organizations today are organized functionally: sales, marketing, finance, engineering,  manufacturing, HR, IT, etc.  And withing these organizations, there are even more specializations.  Marketing has specialists in advertising, public relations, research, distribution channels, and product management.  Engineering has chemical, mechanical, electrical, firmware, and software engineers.  Even in software development, you have specialists in user interfaces, networking, databases. realtime embedded and project management.

One of the critical problems is that most people working in each of these areas become overspecialized.  They spend so much time accumulating and applying specialized knowledge, that they can only communicate with people in their own specialty.  If you don’t believe me, observe a two hour meeting involving somebody from sales, market research, product management, mechanical engineering, electrical engineering, finance, and purchasing.

In Mythical Man Month, Frederick Brooks retells the Tower of Babel as a project management story.  It fits perfectly, because the root cause of the Tower of Babel failure was overspecialization and a failure to communicate.   Today, instead of talking Hebrew, Arabic, Persian and Greek, we talk gross margin, differentiation, segmentation, tensile strength, electromagnetic interference, and virtual inheritance.

And our communication has another quality.  Solution focus.  We routinely argue the flaws and merits of solutions with only the foggiest understanding of what the problem is.  And we use the vast levels of specialized knowledge from our respective disciplines to shout down the cretans who disagree with us.

Cost reduction and efficiency live in the same neighborhood as specialization and analytical thinking:

  • If we replace these two steps with this one, the process will be faster.
  • If we replace this part with this other part, the unit cost will be reduced by 2%.
  • If we consolidate these three models into one, we can reduce inventory by 20%.

If efficiency is “doing things the right way”, then effectiveness is “doing the right things the right way.”  Value lives next door to effectiveness and both live in the same neighborhood as synthesis.  Value, like beauty, is in the  eye of the beholder.  Products and services can deliver benefits, but only the buyers and users can apply these benefits to realize value.  Consider smartphones.  Some people only use their phones for mobile calls, others for text messaging, some to read books on the train.

So in the end, there are a couple of reasons that startups are inherently focused on value.  First, because they are small, specialization is a liability.  Most people in startups do several jobs (well), by necessity.  Second, because they are not yet profitable and self-sustaining, their survival is highly dependent on their surroundings (e.g. customers, competitors, economic conditions).  This requires more synthesis than analysis.

As they grow, their strategy shifts to cost.  Michael Porter writes about this in Competitive Advantage.  And guess what, every one of us bargain-hunting, coupon-clipping, “buy one get one free” consumers is the root cause of this.  Why mention this?  Because synthetic thinkers love systems with feedback loops!

Where Elitism Is Proper?

Ever since I stumbled upon Fred Brooks‘s meta-physical idea of “Conceptual Integrity” in his classic book, “The Mythical Man Month“, I’ve strived mightily to achieve that elusive quality in the software work that I do. Over twenty years ago, Mr. Brooks stated that the greatest conceptually integral designs were the product of one, or at most two, human minds. Fred asserts that his “one or two minds” principle still holds true today:

My fictional alter ego, Bulldozer aught aught, would’ve re-worded the beginning of the statement to “Most, if not all… “, but Fred’s message stills rings loud and true.

According to Fred, in today’s world of exponentially growing complexity and team sizes, conceptual integrity is more difficult to achieve than ever:

Why the increased difficulty? Because as a team grows larger, more minds will collide with each other to express and manifest their incompatible design ideas. Big projects can, and usually do, devolve into “design by committee” fiascos where monstrously over-complicated contraptions get created and foisted upon the world.

Ok, Ok, you say. Enough disclosure of the pervasive problem – we get it Yoda. What’s the solution, bozo? Here it is:

Even though it sounds simple to enact this policy, it’s not. The role of “Chief Designer” in a group of highly educated, independent thinking people is fraught with peril. It requires a dose of discipline imposition that can be perceived as “meanness” to external observers. Too much perceived meanness can cause a supporting team to morph into an unsupporting team and lead to the ejection and ostracism of the chief designer. Too little meanness and the possibility of achieving conceptual integrity goes right out the window – it’s Rube Goldberg city. Bummer.

Does your org explicitly recognize and implement the “Chief Designer” role – which is not the same as the softer, less technical, more politically correct, and more administrative “software lead”, “project manager”, “product manager”, and…….. “software rocket-tect” roles? If your org does formally implement the “Chief Designer” role, are your chief designers kept on a tight leash by higher ranking BUTTS, BMs, BOOGLs, SCOLs or CGHs that have no idea what “conceptual integrity” means? Worse, do your “Chief Designers” (again, if you have any) handcuff themselves in order to increase their promotability?

I’m not into corpo caste systems or stratified command-control hierarchies and I struggle endlessly to fight the instinct to play the “I’m smarter than you” game, but I agree with Mr. Brooks when he asserts that world class product design is one of those rare situations…..

How about you? Where do you stand…… or sit?
