A Tale of Two Cattle Prods Named Reason and Motivation: A Software Architecture Parable, Apparently

Based in the universe created by the The Tale of Thomas, Richard, and Karen — A Software Architecture Parable post.

A Parable

And, it came to pass, in the land of Enterprise Information Technology, that there arose a great need.

Not a real need, mind you.

But, a need nonetheless.

For the business had spoken.

And when the business speaks, the people of IT must listen.

Or, at least schedule a meeting to discuss listening.

And, so it was written in the requirements document, “The system shall be modern.”

And, the architects rejoiced.

For they knew not what modern meant, but they knew it would require Kubernetes and had to have AI.

And, lo, and behold, there was assembled a council of developers, architects, engineers, product owners, project managers, security people, compliance people, and one unfortunate DBA who had merely been walking past the conference room when someone asked, “Does anyone know anything about databases?”

The DBA should have kept walking.

But, that was not his way.

And, thus, began the project.

In the Beginning, There Was Reason

Among the assembled were two great cattle prods.

The first was called Reason.

Reason was a magnificent cattle prod.

• Reason spoke softly.
• Reason presented diagrams.
• Reason produced spreadsheets.
• Reason cited standards.

Reason said things such as:

“Perhaps we should first establish the business requirements.”

And:

“Before selecting the technology, we should identify the architectural constraints.”

And:

“Have we considered whether this problem actually requires a distributed system?”

The others nodded solemnly.

They agreed that these were excellent questions.

They then scheduled another meeting.

For seven weeks they met.

They debated.

They whiteboarded (if that is a verb).

They created decision matrices.

They established working groups.

The working groups established sub-working groups.

The sub-working groups created Jira epics.

The Jira epics spawned seventeen hundred tickets.

And, every ticket had a description.

And, every description had acceptance criteria.

And, every acceptance criterion had an owner.

And, the owners, having seen the scope of their responsibilities, quietly updated their LinkedIn profiles.

Thus, did Reason prosper.

But, the project did not.

For Reason has a weakness.

Reason requires people to agree that the reasonable thing is reasonable.

This sounds obvious.

It is not.

Especially in Enterprise IT.

And, Then Came Motivation

And, after Reason had spoken, another cattle prod appeared.

Its name was Motivation.

Motivation was not subtle.

Motivation did not produce architecture diagrams.

Motivation did not ask whether everyone was aligned.

Motivation did not create a steering committee.

Motivation simply walked into the room and said:

“We are doing this.”

And the people asked:

“Why?”

And Motivation answered:

“Because the CEO said so.”

And, suddenly, there was progress.

For behold, engineers who had spent six months debating whether a service should communicate over REST or asynchronous messaging suddenly became capable of making a decision in approximately fourteen minutes.

Developers who had spent three months discussing coding standards suddenly wrote code.

Security engineers who had demanded seventeen threat models suddenly approved one.

And the project manager discovered that a deadline was, in fact, a thing that could be enforced.

There was much rejoicing.

For approximately eleven minutes.

The Problem With Motivation

For Motivation, too, had a weakness.

Motivation can make people do something.

It cannot necessarily make them do the right thing.

Thus, it came to pass that the development team built exactly what they had been instructed to build.

Which was unfortunate.

Because, nobody had established what should actually be built.

The system was completed on time.

It was delivered under budget.

It passed all the tests.

It was deployed into production.

And, it was completely useless.

The business users looked upon it and said, “That isn’t what we wanted.”

The project manager replied, “But, you signed the requirements.”

The business replied, “Yes.”

The project manager said, “Then what is the problem?”

The business answered, “The requirements were wrong.”

And, there was much weeping.

And, gnashing of teeth.

A couple of people cut out their own stomachs.

And, a new project was created.

The Third Way

And, so the elders of IT gathered upon the mountain.

They brought with them coffee. Lots of coffee.

For the mountain was high.

And, the meeting was scheduled for four hours.

There they pondered the ancient problem: What is the proper way to make technology decisions?

Reason said, “We must understand the problem.”

Motivation said, “We must actually do something.”

Reason said, “We need evidence.”

Motivation said, “We need a decision.”

Reason said, “We should consider the alternatives.”

Motivation said, “We have considered them for six months.”

Reason said, “We need to understand the consequences.”

Motivation said, “The consequences of doing nothing are already unacceptable.”

And, the elders sat in silence.

For both cattle prods were correct.

Which was deeply inconvenient.

And, the Architecture Was Born

Then, there appeared among them an Enterprise Architect.

Not the same Enterprise Architect as in our first tale.

This one had survived more than one transformation program.

He had seen JEE and the rise & fall of EJB.

He had seen SOA.

He had seen REST.

He had seen microservices.

He had seen the Great Kubernetes Migration.

He had witnessed the Serverless Prophecy.

He had once attended a meeting where someone proposed putting a database on a blockchain.

He had therefore seen enough. Never everything, just enough.

And, the Enterprise Architect spoke, “Reason tells us what should be done.”

“Motivation tells us that it must be done.”

“But, neither tells us how to make people care about doing it correctly.”

The people were confused.

So, he explained.

“Reason without Motivation produces endless analysis.”

“Motivation without Reason produces beautifully executed stupidity.”

The people nodded.

For this was wisdom.

And, wisdom, being wisdom, was immediately added to a PowerPoint deck.

The Four Horsemen of Enterprise Architecture

The Enterprise Architect then revealed the four principles.

First: Reason

Understand the problem.

Understand the constraints.

Understand the consequences.

Do not choose technology because someone saw it on LinkedIn.

Do not build a distributed system because distributed systems are cool.

Do not put everything into Kubernetes because someone owns a Kubernetes hoodie.

And, above all, do not confuse a technology preference with an architecture.

Second: Motivation

Once the decision is made, make the decision matter.

Assign ownership.

Set deadlines.

Allocate resources.

Remove obstacles.

Hold people accountable.

Because an architecture decision that nobody is required to follow is not an architecture decision.

It is a suggestion.

And, Enterprise IT already has enough suggestions.

Third: Authority

For Reason and Motivation without authority are merely two unemployed cattle prods.

Someone must be empowered to say, “This is the decision.”

And, then enforce it.

Not endlessly reopen it.

Not revisit it every Tuesday because someone discovered a new framework.

Not create a committee to determine whether the original committee was sufficiently representative.

Decide.

Proceed.

Revisit when the facts change.

Not merely because someone got back from AWS re:Invent.

Fourth: Consequences

Every architectural decision has consequences.

Some are technical.

Some are financial.

Some are operational.

Some are political.

And, some are the sort of consequences that appear three years later in a meeting where someone says, “Who thought this was a good idea?”

The answer, almost invariably, is, “It was a collaborative decision.”

Which means, of course, that nobody did.

And, Thus the Project Proceeded

The team returned from the mountain.

Reason examined the problem.

Motivation established the deadline.

Authority established who could make decisions.

Consequences were documented.

And, the work began.

Thomas the Developer wrote code.

Richard the Data Engineer moved data.

Karen the Integration Architect connected systems.

And, the Enterprise Architect watched them carefully.

Not because he wished to control every detail.

But, because he had learned a terrible truth:

People left unsupervised with architectural freedom will eventually invent an architecture.

And, the architecture they invent will invariably involve:

• Six message brokers
• Three API gateways
• Four identity providers
• A data lake
• A service mesh
• Kubernetes
• And, a database that nobody is allowed to touch because “the platform team owns it.”

And, so the Enterprise Architect kept his cattle prod nearby.

Just in case.

The Moral

And, thus we learn:

• Reason without Motivation becomes analysis paralysis.
• Motivation without Reason becomes organized stupidity.
• Authority without either becomes tyranny.

And, all three without Accountability become an enterprise architecture program.

Which is arguably worse.

The wise architect therefore carries two cattle prods.

One is named Reason.

The other is named Motivation.

Reason asks, “Why are we doing this?”

Motivation asks, “Why haven’t you done it yet?”

And, when the two disagree, the architect should probably stop.

Because, that usually means somebody has gone to the had place and has confused having a decision with having a good decision.

And, somewhere, inevitably, a project manager is already preparing a status report that says: GREEN — On Track

This is how civilizations fall.

Not with a bang.

Not with a revolution.

But, with a PowerPoint slide containing a green circle.
