One of the most expensive mistakes in business is not failure.
It is successfully executing the wrong idea.
You develop the product.
Build the website.
Recruit employees.
Purchase equipment.
Develop systems.
Launch the marketing campaign.
Spend the money.
Then discover something uncomfortable:
Customers do not want what you have built—at least not enough to pay for it.
Eric Ries’s THE LEAN STARTUP: How Today’s Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses attacks this problem directly.
Published in 2011, THE LEAN STARTUP has sold more than one million copies and been published in more than 30 languages. Ries’s ideas helped popularise concepts that have become part of the modern business vocabulary, including the Minimum Viable Product (MVP), Build-Measure-Learn, validated learning and the pivot.
But this is not merely a book for technology start-ups.
That is perhaps the most important misconception SME owners should discard before reading it.
Ries defines a start-up in terms of attempting to create something new under conditions of extreme uncertainty. That can apply to an entrepreneur in a garage, but it can also apply to an established company launching a new product, entering a new market, introducing technology or developing a new business model.
For SME owners and leaders, that makes the book extraordinarily relevant.
Because whenever you are making a significant investment based on assumptions about a future you cannot know with certainty, you face essentially the same problem:
How can we learn whether our assumptions are correct before we spend too much time and money discovering they were wrong?
That is the question at the heart of THE LEAN STARTUP.

Who Is Eric Ries? (Business Growth Perth)
Eric Ries is an entrepreneur, author and creator of the Lean Startup methodology.
His entrepreneurial experience included both failure and success, most notably as co-founder and Chief Technology Officer of IMVU. Ries subsequently developed the ideas that became the Lean Startup methodology and began advising start-ups and established organisations on entrepreneurship, innovation and product strategy.
That background matters.
THE LEAN STARTUP was not written from the perspective of someone claiming entrepreneurship can be reduced to a perfect formula.
Quite the opposite.
It starts from the proposition that entrepreneurship involves uncertainty.
Traditional management works particularly well where an organisation has:
historical information,
reasonably predictable demand,
established processes,
known customers,
understood economics.
Innovation often has none of these.
The customer may be uncertain.
The product may be uncertain.
The pricing may be uncertain.
The distribution channel may be uncertain.
Even the problem the entrepreneur thinks they are solving may be misunderstood.
Ries therefore asks:
How should we manage when we don’t yet know whether our assumptions are correct?
His answer is essentially:
Turn assumptions into experiments and uncertainty into learning.
What Is THE LEAN STARTUP Really About? (Business Improvement Perth)
At first glance, the book appears to be about building start-ups more efficiently.
Its deeper message is about reducing waste when making decisions under uncertainty.
The official Lean Startup methodology describes the approach as scientific experimentation designed to discover whether a sustainable business can be built, rather than spending months or years perfecting a product before discovering whether customers actually care about it.
That distinction is critical.
Suppose you believe customers want a new service.
Traditional thinking may say:
develop the business plan,
build the service,
hire employees,
launch,
measure sales.
Lean thinking asks:
What is the cheapest credible way to test whether customers actually want this before making the full investment?
That changes everything.
The objective becomes not merely to execute efficiently.
It becomes to learn efficiently.
The Five Principles of Lean Startup (Business Growth Perth)
Ries’s methodology rests on five major principles:
Entrepreneurs are everywhere.
Entrepreneurship is management.
Validated learning.
Innovation accounting.
Build-Measure-Learn.
These principles are explicitly identified in the official methodology.
Together they represent a significant shift in thinking.
The traditional question is:
Did we execute the plan?
Lean Startup thinking asks:
What have we learned that proves—or disproves—the assumptions underlying the plan?
That is much more demanding.
You can execute a bad strategy perfectly.
Entrepreneurship Is Management (Leadership Development Perth)
Entrepreneurship is sometimes romanticised.
Vision.
Passion.
Risk-taking.
Creativity.
Disruption.
Ries brings management discipline back into the conversation.
A start-up is an organisation.
It therefore needs management.
But because it operates under significant uncertainty, it requires management methods appropriate to uncertainty.
This is particularly relevant for SME founders.
Entrepreneurial energy may get the business started.
It does not automatically build a scalable organisation.
Eventually you need:
priorities,
budgets,
metrics,
processes,
people,
decision-making,
capital allocation.
The challenge is introducing management discipline without destroying entrepreneurial adaptability.
That tension sits at the heart of many growing SMEs.
Stop Treating Assumptions as Facts (Strategic Planning Perth)
Every strategy contains assumptions.
Customers will buy.
The market will grow.
Employees will be available.
Competitors will react in a particular way.
Prices will hold.
Margins will be achievable.
Technology will work.
Distribution partners will cooperate.
The problem arises when assumptions quietly become facts in management discussions.
Consider:
“Customers want 24-hour service.”
How do we know?
“Customers won’t pay more.”
How do we know?
“There is strong demand in Melbourne.”
How do we know?
“Businesses will pay for this software.”
How do we know?
This is where Lean Startup thinking adds enormous value to strategic planning.
Every important strategic assumption should invite another question:
How could we test that?
Validated Learning (Business Improvement Perth)
Validated learning is one of Ries’s central concepts.
The official methodology describes it as a rigorous way of demonstrating progress when operating under extreme uncertainty. Rather than treating activity as progress, businesses conduct experiments to test elements of their vision.
This distinction is enormously important.
A team can spend six months developing a product and report:
10,000 development hours.
Product completed.
Website launched.
Marketing campaign delivered.
Budget spent.
But what did the business learn?
Do customers want it?
Will they pay?
Will they return?
Can we acquire customers economically?
Will they recommend it?
Those questions tell us whether commercial progress has actually occurred.
Build-Measure-Learn (Business Growth Perth)
The most famous concept in THE LEAN STARTUP is the:
Build → Measure → Learn
feedback loop.
Ries describes the fundamental activity of a start-up as converting ideas into products, measuring customer responses and learning whether to pivot or persevere. The objective is to accelerate that feedback loop.
The logic is deceptively simple.
Build
Create the smallest credible experiment capable of testing an important assumption.
Measure
Observe what customers actually do.
Learn
Determine whether the evidence supports the hypothesis.
Then repeat.
The faster the cycle turns, the faster the organisation converts uncertainty into knowledge.
And knowledge allows capital to be allocated more intelligently.
The Minimum Viable Product (Business Growth Perth)
The Minimum Viable Product, or MVP, is probably the most widely recognised Lean Startup concept.
It is also one of the most misunderstood.
The objective of an MVP is not to create a cheap, poor-quality version of the final product.
It is to create enough of an offering to test a critical assumption and generate meaningful learning.
The official Lean Startup methodology positions the MVP as the starting point for learning as quickly as possible before further development.
An MVP might therefore be:
a prototype,
a landing page,
a pilot program,
a manual service,
a limited geographic launch,
a mock-up,
a demonstration,
a small customer trial.
For an SME, the principle is powerful:
Do not build everything necessary for eventual success before testing whether the underlying proposition deserves to exist.
What an MVP Is Not (Business Growth Perth)
This deserves emphasis.
MVP does not mean:
poor quality,
unsafe,
unprofessional,
unethical,
non-compliant,
unfinished rubbish.
The word viable matters.
A minimum viable offering must still allow the business to obtain useful evidence.
For example, a transport company considering a new service does not need to purchase ten trucks to test demand.
It might subcontract initial capacity.
A consulting firm considering a new service does not need a complete online platform.
It might manually deliver the first engagements.
A manufacturer considering a new product does not necessarily need a full production line.
It might prototype.
The objective is:
Maximum learning for the minimum sensible commitment of resources.
Measure What Matters (Business Improvement Perth)
Measurement is fundamental to Lean Startup thinking.
But measuring more things does not necessarily improve decisions.
The challenge is determining what information tells management whether its underlying assumptions are becoming more or less credible.
Suppose website traffic increases by 300%.
Excellent.
But:
Did enquiries increase?
Did qualified leads increase?
Did customers increase?
Did revenue increase?
Did customer acquisition cost improve?
Traffic itself may mean very little.
This leads to another important distinction in Ries’s work.
Vanity Metrics Versus Actionable Metrics (Business Improvement Perth)
Vanity metrics make us feel successful.
Page views.
Downloads.
Followers.
Registrations.
Total customers.
Headline revenue.
But they can conceal poor economics.
Actionable metrics help management understand cause and effect and determine what should happen next. The Lean Startup methodology specifically stresses actionable metrics capable of demonstrating cause and effect.
For SMEs, better questions include:
What percentage of leads convert?
What does acquiring a customer cost?
How many customers repurchase?
What is gross margin by customer?
What is churn?
What is average revenue per customer?
How quickly does a new customer become profitable?
These metrics improve decisions.
Innovation Accounting (Business Improvement Perth)
Traditional accounting tells us whether an established business is financially successful.
Start-ups and experimental initiatives require additional measures.
Ries calls this innovation accounting.
Its purpose is to establish meaningful measures of progress, milestones and priorities where traditional financial results may initially tell management very little.
Suppose a new service has generated only $20,000 revenue.
Is that good or bad?
We cannot know without context.
Perhaps:
customer retention is extraordinary,
acquisition cost is declining,
referrals are accelerating,
customers are upgrading,
gross margins are excellent.
Or perhaps the opposite is true.
Innovation accounting asks whether the underlying drivers are improving.
Pivot or Persevere (Business Growth Perth)
Eventually, experimentation needs to produce a decision.
Do we continue?
Or change direction?
Ries calls this:
pivot or persevere.
A pivot is not simply giving up.
Nor is it random change.
The official methodology describes a pivot as a structured course correction designed to test a new fundamental hypothesis while retaining something learned from the existing direction.
This distinction matters psychologically.
Founders can become emotionally attached to ideas.
They have invested:
time,
money,
reputation,
identity.
Changing direction can feel like admitting failure.
Lean Startup thinking reframes the issue.
If the experiment proves the original hypothesis wrong, learning has occurred.
The failure would be ignoring the evidence.
The Different Forms of Pivot (Business Growth Perth)
A business can pivot in many ways.
The product may change.
The customer segment may change.
The channel may change.
The pricing model may change.
The technology may change.
The problem being solved may change.
The revenue model may change.
This is relevant well beyond start-ups.
Established SMEs pivot too.
A wholesaler moves direct-to-consumer.
A manufacturer introduces services.
A transactional business adopts subscriptions.
A local operator becomes national.
A product company becomes technology-enabled.
The strategic discipline is knowing what should remain constant and what evidence suggests should change.
Small Batches and Faster Learning (Business Improvement Perth)
Lean manufacturing influenced Ries’s thinking, including the idea of working in smaller batches.
The official book structure specifically identifies small batches as one of the techniques used to accelerate Build-Measure-Learn as organisations scale.
For SMEs, the lesson is straightforward.
Large projects create large assumptions.
Large assumptions create large risks.
Instead of:
twelve-month development,
consider:
four-week experiments.
Instead of:
national rollout,
consider:
one location.
Instead of:
full automation,
consider:
one process.
Small batches shorten the distance between action and feedback.
The Five Whys (Business Improvement Perth)
Ries also incorporates the Five Whys, a root-cause technique originating from lean management.
When something goes wrong, ask why.
Then ask why again.
Continue until the underlying cause becomes clearer.
The official Lean Startup methodology identifies the Five Whys as a way of investigating and solving problems as they arise.
Suppose a customer delivery was late.
Why?
The order wasn’t dispatched.
Why?
The warehouse didn’t receive the request.
Why?
The system failed to transmit it.
Why?
The integration was incorrectly configured.
Why?
Testing responsibilities were unclear.
Now the problem looks very different.
The objective is not merely to fix the late delivery.
It is to fix the systemic cause.
The Importance of Speed (Business Growth Perth)
Speed matters enormously in Lean Startup thinking.
But not because rushing is inherently good.
Speed matters because faster feedback produces faster learning.
The question is not:
How quickly can we build?
It is:
How quickly can we discover whether we should build?
That distinction can save SMEs enormous amounts of money.
Three months spent discovering a proposition does not work may feel disappointing.
Three years and $2 million discovering exactly the same thing is much worse.
The Lean Startup and Strategic Planning (Strategic Planning Perth)
Some readers mistakenly interpret THE LEAN STARTUP as an argument against planning.
It is better understood as an argument against treating plans as certainty where uncertainty is high.
Traditional planning remains enormously useful for:
cash flow,
capacity,
budgets,
resource allocation,
established operations.
But innovative initiatives require more adaptability.
This suggests a powerful approach for SMEs:
Plan what can reasonably be planned.
Experiment where assumptions remain uncertain.
Your strategic plan should therefore identify not only objectives and actions, but also:
Which assumptions must be tested?
That improves strategic thinking considerably.
The Lean Startup and Established SMEs (Business Growth Perth)
Perhaps the most important message for my SME audience is this:
You do not need to be a start-up to think like one.
Ries explicitly argues that entrepreneurs exist everywhere and that the methodology can apply inside organisations of different sizes.
An established SME can apply Lean Startup thinking when:
launching a product,
entering a geographic market,
introducing AI,
changing pricing,
developing an online channel,
acquiring a business,
creating a new division,
testing a subscription model,
changing customer segments.
Whenever uncertainty is high, experimentation becomes useful.
Testing New Products and Services (Business Growth Perth)
Suppose you believe customers want a new premium service.
Do not begin by building the entire infrastructure.
Test the proposition.
Speak to customers.
Offer the service manually.
Pre-sell it.
Run a pilot.
Measure response.
Ask:
Who bought?
Why?
Who refused?
Why?
What did they value?
What would they change?
Then refine.
The objective is not to ask customers whether they like the idea.
People are generous with hypothetical enthusiasm.
The stronger evidence is behaviour.
Will they actually buy?
Testing Pricing (Business Improvement Perth)
Pricing is particularly suited to experimentation.
Owners frequently say:
“Customers won’t pay more.”
That is a hypothesis.
Test it.
Try different packages.
Introduce premium options.
Test price increases with particular segments.
Measure conversion and retention.
Sometimes fewer customers at higher prices produce substantially better economics.
The principle remains:
Replace opinion with evidence wherever practicable.
Testing New Markets (Business Growth Perth)
Suppose a Perth SME wants to enter Melbourne.
Traditional thinking might involve:
office,
employees,
vehicles,
warehouse,
marketing,
management.
That creates substantial fixed cost before demand has been validated.
Lean thinking asks:
Can we test Melbourne demand first?
Perhaps through:
digital marketing,
existing partners,
temporary facilities,
contractors,
limited customer acquisition,
a sales representative.
Once evidence strengthens, investment can increase.
This is not timidity.
It is disciplined capital allocation.
Testing Business Models (Business Growth Perth)
Products are not the only things that can be tested.
Business models can too.
Could customers pay monthly rather than per transaction?
Could maintenance be bundled?
Could a product become a service?
Could a marketplace replace inventory ownership?
Could recurring revenue replace irregular sales?
Could direct distribution improve margins?
This connects strongly with business model innovation.
A business model is itself a collection of assumptions.
Lean thinking provides a method for testing them.
Lean Thinking and Capital Allocation (Business Advisor Perth)
This may be one of the most commercially valuable applications for established SMEs.
Capital is finite.
Therefore, large uncertain investments should generally face stronger evidence requirements.
Instead of:
Idea → Full Investment
consider:
Idea → Hypothesis → Experiment → Evidence → Limited Investment → More Evidence → Scale
This creates investment gates.
At each stage management asks:
What did we expect?
What happened?
What did we learn?
Has uncertainty reduced?
Should we invest more?
That is disciplined business advisory thinking.
It helps prevent enthusiasm from outrunning evidence.
Lean Startup and AI (Business Growth Perth)
The Lean Startup methodology is particularly relevant to today’s AI environment.
SMEs are being encouraged to adopt:
generative AI,
automation,
AI agents,
predictive analytics,
customer-service tools,
marketing automation.
The temptation is to buy technology first and search for the business case afterwards.
Lean thinking suggests the reverse.
Start with the problem.
Form the hypothesis.
Run the experiment.
Measure the result.
Then scale.
For example:
Hypothesis: AI can reduce proposal preparation time by 50% without reducing quality.
Test it.
Measure it.
Learn.
Then decide.
This is much more sensible than announcing an “AI transformation” because everybody else is talking about AI.
Where Lean Startup Thinking Can Go Wrong (Business Advisor Perth)
THE LEAN STARTUP is highly influential, but its ideas can be misused.
Mistaking MVP for Poor Quality
Minimum viable does not mean minimum acceptable standards.
Experimenting Forever
At some point businesses need to commit.
Constant testing can itself become procrastination.
Ignoring Strategy
Experiments need strategic context.
Otherwise organisations optimise fragments without determining whether the overall direction makes sense.
Overreacting to Small Samples
Early data can mislead.
One customer does not necessarily represent a market.
Ignoring Brand Risk
Established businesses have reputations to protect.
Experiments visible to customers need appropriate quality control.
Ignoring Regulation and Safety
In healthcare, transport, financial services, construction and other regulated industries, some things simply cannot be “tested” casually.
Pivoting Too Quickly
Persistence matters too.
Poor early results do not always invalidate the underlying strategy.
Sometimes execution needs improvement.
The challenge is determining whether the hypothesis or the execution is failing.
What Eric Ries Gets Particularly Right (Business Growth Perth)
The book’s greatest contribution is arguably philosophical rather than procedural.
It changes the definition of progress.
Progress is not:
working harder,
building more features,
spending the budget,
completing the project plan.
Progress is:
reducing important uncertainty about whether a sustainable business can be built.
That is profound.
It challenges leaders to stop rewarding activity merely because activity is visible.
The official Lean Startup methodology makes this explicit through validated learning and innovation accounting.
For SMEs, the result can be:
less wasted capital,
faster learning,
better products,
better strategic decisions,
earlier abandonment of weak ideas,
greater willingness to innovate.
A Practical LEARN Framework for SME Owners & Leaders (Business Growth Perth)
The principles of THE LEAN STARTUP can be translated into a practical SME framework.
L — LIST THE ASSUMPTIONS
What must be true for this idea to succeed?
E — EXPERIMENT
What is the smallest credible test?
A — ANALYSE BEHAVIOUR
What did customers actually do?
R — RESPOND TO EVIDENCE
What does the result tell us?
N — NEXT DECISION
Do we persevere, modify, pivot or stop?
In shorthand:
List → Experiment → Analyse → Respond → Next Decision
This is not Ries’s own acronym. It is a practical SME application of his underlying principles.
The crucial point is that the cycle repeats.
Each experiment should make the next decision more informed than the last.
Practical Recommendations for SME Owners & Leaders (Business Growth Perth)
Before committing substantial resources to a new initiative, ask:
- What problem are we trying to solve?
- Who experiences that problem?
- What evidence proves it matters?
- What are we assuming?
- Which assumption is most dangerous if wrong?
- How could we test that assumption?
- What is our MVP?
- What customer behaviour would constitute meaningful evidence?
- Which metrics genuinely matter?
- Are we relying on vanity metrics?
- What would cause us to stop?
- What would justify further investment?
- How quickly can we complete one Build-Measure-Learn cycle?
- Are we investing faster than we are learning?
- What have customers actually done—not merely said?
- What have we learned that surprised us?
- Are we emotionally attached to the original idea?
- Should we pivot or persevere?
- What is the next cheapest useful experiment?
- What would we do differently if this were our own money?
For SME owners, that final question is usually unnecessary.
It often is your own money.
Which makes disciplined experimentation even more important.
Key Takeaways (Business Growth Perth)
THE LEAN STARTUP offers SME owners and leaders a powerful collection of principles.
Entrepreneurship exists wherever organisations operate under significant uncertainty.
Entrepreneurship requires management discipline.
Assumptions should be tested rather than quietly treated as facts.
Validated learning is a meaningful measure of progress under uncertainty.
Build-Measure-Learn converts ideas into evidence.
An MVP should maximise useful learning without unnecessary investment.
Minimum viable does not mean poor quality.
Actionable metrics are more valuable than vanity metrics.
Innovation accounting helps measure progress before traditional financial metrics become meaningful.
Pivoting is a structured change of direction, not simply giving up.
Small batches reduce the cost and time required to learn.
The Five Whys can help uncover root causes.
Speed matters because faster feedback creates faster learning.
Strategic planning and experimentation should complement rather than replace one another.
Established SMEs can apply Lean Startup principles to new products, markets, pricing, technology and business models.
Capital commitments should increase as evidence strengthens.
And perhaps the most important lesson:
Do not spend enormous amounts of money proving something you could have tested cheaply.
Frequently Asked Questions About THE LEAN STARTUP (Business Growth Perth)
What is THE LEAN STARTUP by Eric Ries about?
The book presents a scientific approach to entrepreneurship and innovation based on experimentation, validated learning, Build-Measure-Learn, MVPs, innovation accounting and decisions about whether to pivot or persevere.
When was THE LEAN STARTUP published?
THE LEAN STARTUP was published in 2011. Ries’s current website states that it has subsequently sold more than one million copies and appeared in more than 30 languages.
What are the five Lean Startup principles?
They are Entrepreneurs Are Everywhere, Entrepreneurship Is Management, Validated Learning, Innovation Accounting and Build-Measure-Learn.
What is Build-Measure-Learn?
It is a feedback loop in which a business builds an experiment or product, measures customer response and learns whether its underlying assumptions are supported.
What is a Minimum Viable Product?
An MVP is the minimum credible version or experiment needed to begin testing important assumptions and learning from actual customers without unnecessarily building the complete offering first.
Does MVP mean launching a poor-quality product?
No. The objective is to minimise unnecessary development while obtaining meaningful evidence. Safety, regulatory requirements, brand standards and essential customer expectations still matter.
What is validated learning?
Validated learning is Ries’s approach to demonstrating genuine progress through experiments that test assumptions about how a sustainable business can be created.
What are vanity metrics?
They are numbers that may appear impressive but provide little useful information about whether the business model is actually improving.
What is innovation accounting?
Innovation accounting provides milestones and measures for evaluating progress in uncertain new ventures where conventional financial accounting alone may initially provide insufficient insight.
What does pivot or persevere mean?
It means deciding, based on learning and evidence, whether to continue broadly along the existing path or make a structured change to an important aspect of the business hypothesis.
Is THE LEAN STARTUP only relevant to technology companies?
No. Ries’s definition of entrepreneurship centres on operating under extreme uncertainty, and his principles are explicitly intended to apply beyond garage start-ups and into established organisations.
Can established SMEs use Lean Startup principles?
Yes. They are particularly useful when testing new products, services, markets, pricing structures, technologies, channels or business models.
Does Lean Startup thinking replace strategic planning?
No. Strategic planning establishes direction and resource priorities, while experimentation can test important assumptions where uncertainty remains high.
Can Lean Startup principles help reduce financial risk?
Yes. Testing important assumptions before committing substantial resources can reduce the amount of capital exposed to unvalidated ideas.
What is the biggest lesson from THE LEAN STARTUP?
Perhaps the biggest lesson is to stop equating execution with progress. Under uncertainty, progress comes from learning what actually works before committing disproportionate resources.
Conclusion: Stop Asking Whether You Can Build It—First Determine Whether You Should (Business Growth Perth)
Business owners are naturally action-oriented.
That is often why they became entrepreneurs in the first place.
See an opportunity.
Make a decision.
Invest.
Build.
Sell.
Grow.
But entrepreneurial decisiveness has a dangerous counterpart:
We can become so committed to executing an idea that we stop questioning whether the assumptions beneath it are correct.
That is where THE LEAN STARTUP makes its greatest contribution.
Eric Ries does not tell entrepreneurs to stop taking risks.
He provides a framework for becoming more intelligent about which risks deserve to be taken.
The distinction is enormously important.
Imagine two businesses pursuing the same opportunity.
Business A spends $1 million building the complete solution and then launches.
Business B spends $50,000 testing the most important assumptions first.
Suppose customers dislike the proposition.
Business A has lost substantial capital and perhaps a year.
Business B has bought valuable information for $50,000.
Now suppose customers love it.
Business B can invest more confidently because uncertainty has reduced.
That is the essence of Lean Startup thinking.
Learn before you scale.
For SME owners, this has applications far beyond starting a new company.
Before opening another branch:
test demand.
Before buying substantial equipment:
test utilisation assumptions.
Before entering another state:
test customer acquisition.
Before developing expensive software:
prototype the workflow.
Before creating a new service:
sell it to a few customers.
Before adopting new technology:
test the business case.
Before assuming customers will reject a price increase:
test the assumption.
Before investing millions in an acquisition:
test the strategic assumptions behind the transaction.
This does not eliminate risk.
Nothing can.
It does something more useful.
It turns uncertainty into a management problem rather than a gambling problem.
And that may be the most enduring lesson from THE LEAN STARTUP.
The successful SME of the future will not necessarily be the organisation with the best original plan.
It may be the organisation that can learn faster than its competitors.
Build.
Measure.
Learn.
Then build again.
Not because endless experimentation is the objective.
But because each cycle should bring the organisation closer to understanding what customers genuinely value, what economics genuinely work and where scarce capital can create the greatest return.
Ries’s official methodology poses the issue particularly well: the important questions are not simply whether a product can be built, but whether it should be built and whether a sustainable business can be created around it.
For SME owners and leaders, that is an extraordinarily valuable discipline.
Don’t fall in love with your solution.
Fall in love with understanding the problem.
Don’t mistake assumptions for evidence.
Don’t mistake activity for learning.
Don’t spend heavily where you can test cheaply.
And above all:
Before you scale the investment, validate the opportunity.
