10. 1. Introduction to the concept of ‘Lean’
1.1 What is ‘Lean’?
This workshop centres around the application of concepts borrowed from the
LEAN MANUFACTURING revolution, which was an approach pioneered by Taiichi
Onho and Shigeo Shingo at Toyota, leading to the much-famed Toyota Production
System (TPS). TPS is renowned for its focus on reduction of the original
Toyota seven wastes to improve overall customer value.
Lean manufacturing or lean production, often simply "lean", is a systemic
method for the elimination of waste within a manufacturing process. Lean also
takes into account waste created through overburden and waste created through
unevenness in work loads.
Working from the perspective of the client who consumes a product or service,
"value" is any action or process that a customer would be willing to pay for.
In-line with the above, essentially, lean is centered on making obvious what adds
value by reducing everything else, viz. “waste”, using a set of ‘tools’ that assist in
the identification and steady elimination of the same.

13. 1. Introduction to the concept of ‘Lean’
1.4 Summary – What ‘Lean’ taught us?
The Lean approach taught the world the difference between value-creating
activities and waste, and showed how to build quality into products from the inside
out, by focusing on the following (for instance):
shrinking of batch sizes,
just-in-time production,
inventory control,
acceleration of cycle times,
continuous improvement,
focused problem solving,
learning from failure quickly,
scaling-up based on success,
drawing on the knowledge and creativity of individual workers
Through this workshop, we learn how to adapt the ideas from the ‘lean’ approach
pioneered at Toyota, to the context of entrepreneurship and the world of startups.

1.6 Where do we go from here?
In-line with the learning outcomes of this workshop, after explaining Phase 2 and
3, we will explain an innovative method to perform business modelling.
On Day 2, we follow-up this activity with another novel set of tools to revolutionize
your business plans.
20. 2. Phase 1: Vision
2.1 Start
We start by appreciating that startup entrepreneurship involves management of a
different nature.
Classical and traditional rules of management do not necessarily translate into
guaranteed startup success, as:
They may impede the creative and the dynamically adaptable process which
leads to innovation
They may not work entirely in an extremely uncertain, complex and at times
‘chaotic’ nature of startups in general
They may invite bureaucracy at an early stage which may not be conducive for
the early success a startup craves for
The same principles do, however, work very well in a more stable work
environment, where there has been a long history of success through years of
hard-work and perseverance.
21. 2. Phase 1: Vision
2.2 Define
Before we describe the principles of Lean Startup in detail, it is important to define
an entrepreneur and a startup
Entrepreneur
An entrepreneur is a person who finds ways to convert raw materials of innovation
into successful ventures and is well-equipped by a proper team structure and
composition, a strong vision for the future and a naturally risk-taking ability.
Startup
A startup is a human institution designed to create a new product or service under
conditions of extreme uncertainty.
Lean Startup methodologies are not restricted to startups alone!
In fact, they are applicable to companies of all sizes and shapes, working in any
industry or sector, at any stage of development.
22. 2. Phase 1: Vision
2.3 Learn: Concept of Validated Learning
It is often said, “We learn from our failures”. Very true!
Learning is a continuous process in general, but unfortunately learning is also an
excuse for managers who fail to achieve the results so promised. Learning can be a
cold comfort to employees who are following an entrepreneur into the unknown.
As per the Lean Startup Methodology, learning assumes the most critical role and
it does so through the concept of Validated Learning. Validated learning is:
The process of demonstrating empirically that a team has discovered valuable
truths about a startup’s present and future business prospects.
It is more concrete, accurate and faster than market forecasting or business
planning.
It is the principal antidote to the lethal problem of achieving failure successfully
(and quickly!) executing a plan that leads nowhere
23. 2. Phase 1: Vision
2.3 Learn: Concept of Minimum Viable Product
Minimum Viable Product is the product, constituting minimum features and
developed by investing minimum resources, as a test or an experiment to
determine the response of the customers upon purchase.
An MVP approach can help us learn
about what the customer truly values
before we’ve invested too much time and
money into building something they
don’t need or want. Our work is not done
until the customer is, in fact, delighted.
24. 2. Phase 1: Vision
2.3 Learn: Building an MVP – all what Lean Startup
focuses onBuild:
Build the MVP, as an experiment, as quickly as
possible that will allow you to test a clear
hypothesis (set of assumptions) we have about
our product or strategy
Measure:
Measure the impact of the MVP in the
marketplace using actionable metrics that help
us analyze customer behavior and feedback
Learn:
Learn whether our original assumptions about
the product, process, and customer needs
were correct or whether we need to change
strategies to better meet our vision
Build
Measure

Repeat this

LEAN APPROACH
25. 2. Phase 1: Vision
2.3 Learn: Building an MVP – all what Lean Startup
focuses on
Build-Measure-Learn feedback loop
does not end once we’ve put our
first product into the market.
Every new launch of an MVP is an
opportunity to gain valuable
information about how well we’re
meeting customer needs - and
whether we need to adjust our
strategy or not.

FEEDBACK LOOP
Fundamentals of the
LEAN APPROACH
26. 2. Phase 1: Vision
2.4 Experiment: Just like we did in our Science Labs at
school!The Lean Startup Methodology reconceives a startups efforts and all what they
develop in the name of products, as experiments (in the form of MVPs) that test its
strategy to see which parts of the product are brilliant and which are not-so-
brilliant.
A true experiment follows the scientist method.
It begins with a clear hypothesis that makes prediction about what is supposed
to happen.
It then test those predictions empirically through customer interaction and
feedback.
Just a scientific experimentation is informed by theory, startup experiments are
guided by startup's vision. The goal of every startup experiment is to discover
how to build a sustainable business around that vision.
27. 2. Phase 1: Vision
2.4 Experiment: What to remember whilst doing so?
Think big, start small
This implies that your ultimate goals should be big but realistic as well, but invest
little resources into the business so that the risk involved is less.
For long term change, experiment immediately
Long term change in the system requires an immediate need to experiment and
imply the changes as needed this work should be fast tracked in a manner to
achieve the long term goals through immediate and prompt changes.
Break it Down
This steps include the breakdown of the grand vision into its component parts.
28. 2. Phase 1: Vision
2.4 Experiment: Assumptions and how to make them?
The two most important assumptions entrepreneurs make are:
Value Hypothesis testing whether a
product or service really delivers value to
customers once they are using it.
Growth hypothesis testing how new
customers will discover a product or
service, and how to increase our
customer growth.
29. 2. Phase 1: Vision
2.4 Experiment: Important Facts
Experiments take less time (than traditional strategic planning alone!),
provide a more accurate gauge, and a real picture of our market size.
An experiment is more than just a theoretical model, in a lean model it is
treated as a first product.
If this or any other experiment is successful, it allows the managers to get
started with his or her campaign: enlisting early adopters, adding employees
to each further experiment or iteration and eventually starting to build a
product.
This way by the time that product is ready to be distributed widely, it will
already have established customer’s unlike a traditional strategic planning or
market research process.
This approach has its roots in feedback on what is working today, rather than
in anticipation of what might work tomorrow.
30. 2. Phase 1: Vision
2.4 Experiment: Split Testing – A key approach
A split or A/B test is an experiment in which different versions of a product are
offered to customers at the same time.
The goal of a split test is to observe differences in behavior between the two
groups and to measure the impact of each version on an actionable metric.
A/B testing can also be performed in serial fashion where a group of users one
week may see one version of the product while the next week users see another.
Though, caution must be observed at times whilst following this approach where
external events may influence user behavior one time period but not the other.
For example, a split test of two ice cream flavors performed in serial during the
summer and winter would see a marked decrease in demand during the winter
where that decrease is mostly related to the weather and not to the flavor offer.
31. Case Studies 1 and 2
Testing your knowledge of Vision (DEFINE and EXPERIMENT)
32. Case Study 1
Startup: Web App
In 2010, Justin and Eric were fresh on the startup scene. With two months of client
business under their belt and the launch of their first “web app“, they discovered a new
problem that they thought could be solved, Social Media Management.
While there were plenty of tools available, the process of learning how to use them
effectively (for business) was complicated. They tried many of the typical software
solutions that were available, but their clients rarely succeeded with these tools. Most
of the time, they became even more frustrated than ever.
The problem with those tools was that while they technically allowed users to complete
social media tasks, they were messy and did little to help make customers actually
better at social media marketing. Business owners are busy, and they found that the
failure rate was rising with these products.
33. Case Study 1
Case Analysis
Question 1: What could have been the problem they faced?
Question 2: What according to you could be the solution to their problem?
Question 3: What strategy would you suggest, to help solve their problem?
34. Case Study 2
The Story of Zappos – Online Shoes Retail
Founder Nick Swinmurn was frustrated because there was no central, online site with a great
selection of shoes which gave him the idea to create a shoe Mega Online Store.
Swinmurn could have waited long time and might have employed a lot of its financial resources on
promotion and warehousing.
Instead he started by running experiment and tested the market by asking local shoe store if he
could take pictures of their inventory. In exchange for permission to take pictures, he would post
the pictures online and come back to buy the shoes at full price if a customer bought them online.
Zappos began with a tiny, simple product – shoes, it was designed to answer one question above
all; is there already sufficient demand for a superior online shopping experience for shoes,
however a well-designed startup experiment like the one Zappos began with does more than test a
single aspect of a business plan. In the course of testing this first assumption, many other
assumptions were tested as well.
35. Case Study 2
The Story of Zappos – Online Shoes Retail
Question 1: What approach did Swinmurn follow to increase his appeal?
Question 2: How did this approach help?
Question 3: What other assumptions he have tested following his approach?
Question 3: How can you apply this to your Business?
37. Activity 1
Comparing the Lean Startup approach with the
TraditionalThis activity will help you choose, which of the two approaches Lean or
Traditional work for your business.
This activity will be a group discussion / debating activity, which will involve the
class to be divided into 2 groups. Each group will either speak for Lean
Approach or the Traditional Approach.
Points of discussion will be the differences in strategies. Each group will choose
an individual from their group to write down all the points being discussed for
their respective topic. Then these points will be discussed in detail against their
pros and cons.
Finally, after the activity it will be up to you to decide which approach suits
your business / idea the best.
39. 3. Phase 2: Steer
3.1 Leap
This phase introduces the leap way of developing – which means that once the
vision is explored, it is time to make certain assumptions and put the things into
action to develop the MVP.
The riskiest elements of a startup plan are the assumptions (Value Hypothesis
and Growth Hypothesis) and that is why they are referred to as leap-of-faith
assumptions. These assumptions canmake or break your business.
Example of a leap-of-faith assumption:
In the iPod business, one of those leaps
of faith was that people would pay for
music.
40. 3. Phase 2: Steer
3.1 Leap: Making better (and safer!) assumptions
Assumptions can be made fool-proof and safer by following:
Genchi Gembutsu: Japanese for “Go and see for yourself”.
Means that business should be based on deep firsthand knowledge. Until you
have seen something for yourself firsthand, you cannot be sure you really
understand any part of the business problem.
Getting external customer data
The facts that we need to gather about customer exist only outside the building,
not inside. So it is imperative to step out of the building and collect REAL data!
Setting-up early customer contact
Early contact with the customer clarifies a basic coarse level that we can use to
craft a customer archetype – a brief document that seeks to humanize the
proposed target customer.
41. 3. Phase 2: Steer
3.2 Test
Once the leap-of-faith assumptions are in place, all efforts should spring into the
development of the MVP.
When building your MVP, remove any feature, process or effort that does not
contribute directly to the learning you seek. Even a low quality MVP can act in
service of building a great high-quality product.
After building the MVP, it is important to
test it and seek continuous feedback.
This can be done by continually bringing
in people to react to mockups, demos,
prototypes and simulations.
42. 3. Phase 2: Steer
3.2 Test: Journey to finding the right customer!
43. 3. Phase 2: Steer
3.2 Test: Make use of early adopters!
Sell the early versions of your products at cheaper rates or for free, to a select
group of customers, before selling to a mass audience, and term them as early
adopters.
Early adopters are a special breed of customers.
They accept – in fact prefer – an 80 percent solution; you don’t need a perfect
solution to capture their interest!
Early adopters use their imagination to fill in what a product is missing.
They prefer that state of affairs, because what they care about above all is
being the first to use or adopt a new product or technology.
Early adopters are suspicious of something that is too polished; if it’s ready for
everyone to adopt, how much advantage can one get by being early.
44. 3. Phase 2: Steer
3.2 Test: Simulanis Early Adopters (Thanks to them!)
45. 3. Phase 2: Steer
3.3 Measure
After developing the MVP and testing the leap-of-faith assumptions, a startup
should rigorously measure where it is right now.
This involves confronting the hard truths which tests and assessments reveal and
then re-devising experiments to learn how to move the real numbers closer to the
ideal reflected in the business plan.
This can be done through innovation accounting.
Innovation accounting is a disciplined and a systematic approach to figure out if we
are making progress and discovering if we are actually achieving validated learning.
It is an alternative to traditional accounting, designed
specifically for startups, and begins by turning the leap-of-
faith assumptions into a quantified financial model.
46. 3. Phase 2: Steer
3.3 Measure: How Innovation Accounting works?
Innovation Accounting works in three steps:
1. Use a MVP to establish real data on where the
company is right now
2. Startups must attempt to tune the engine from the
baseline toward the ideal.
3. After the startup has made all the micro changes and
product optimizations it can move its baseline toward
the ideal, the company reaches a decision point: pivot
or preserve.
47. 3. Phase 2: Steer
3.3 Measure: Importance of Innovation Accounting
The innovation accounting framework makes it clear when the
company is stuck and needs to change direction.
The ‘real’ importance of innovation accounting
Only 5 % of entrepreneurship is the big idea, the business model,
the whiteboard strategizing, and the splitting up of the spoils.
The other 95 % is the gritty work that is measured by innovation
accounting: product prioritizing decisions, deciding which
customers to target or listen to, and having the courage to subject a
grand vision to constant testing and feedback.
48. 3. Phase 2: Steer
3.3 Measure: The Metrics
The 3 A´s of Metrics:
Actionable
For a report to be considered actionable, it must demonstrate clear cause and
effect. Otherwise it is a vanity metric. When cause and effect is clearly understood,
people are better able to learn from their actions. Human beings are innately
talented learners when given a clear and objective assessment.
Accessible
Departments too often spend their energy learning how to use data to get what
they want rather than as genuine feedback to guide their future actions.
Remember that metrics are people, too. Everyone must understand the reports.
Auditable
We must ensure that the data is credible to employees.
49. 3. Phase 2: Steer
3.4 Pivot
Pivot or Preserve is defined as a structured course correction designed to test a new
fundamental hypothesis about the product, strategy and engine of growth.
A pivot requires that we keep one foot rooted in what we have learned so far, while
making a fundamental change in strategy in order to seek even greater validated
learning.
Vanity metrics can allow entrepreneurs to form false conclusions and live in their
own private reality.
When an entrepreneur has an unclear hypothesis, it’s almost impossible to
experience complete failure, and without failure there is usually no impetus to
embark on the radical change a pivot requires. You will always succeed - in seeing
what happens. You won’t know whether to pivot or preserve.
The heart of the lean startup: A pivot is not just an exhortation to change. It is a
special kind of structured change designed to test a new fundamental hypothesis
about the product, business model and engine of growth.
50. 3. Phase 2: Steer
3.4 Pivot: Understanding it better
51. 3. Phase 2: Steer
3.4 Pivot: Types
Zoom-in Pivot: What preciously was considered a single feature in a product
becomes the whole product?
Zoom-out Pivot: What was considered as the whole product becomes a single
feature of a much larger product.
Customer segment Pivot: The product hypothesis is partially confirmed, solving
the right problem, but for a different customer than originally anticipated.
Customer need Pivot: The product hypothesis is partially confirmed: the target
customer has a problem worth solving, just not the one that was originally
anticipated.
Platform Pivot: Refers to a change from an application to a platform or vice
versa.
52. 3. Phase 2: Steer
3.4 Pivot: Types
Business-architecture Pivot: For example, when a startup goes from high
margin/low volume to mass market or vice versa.
Value-capture Pivot: How do companies capture value?
Engine-of-growth Pivot: A company changes its growth strategy to seek faster or
more profitable growth.
Channel Pivot: Is the recognition that the same basic solution could be
delivered through a different channel with greater effectiveness.
Technology Pivot: When discovering a technology to achieve the same solution
by using a completely different technology.
54. Case Study 3
Online Grocery Store – What Went Wrong?
Jimmy Cray Pvt. Ltd in the initial stage of its incorporation developed a new
product, powered by splashy launch, the company successfully executed its
plan. Unfortunately, Customers did not flock to the product in great numbers.
Even worse, the company had invested in massive infrastructure, hiring and
support to handle the influx of customers, expecting huge volume of
customers. When the customers failed to materialize, the company could not
adapt, in time. They achieved failure – successfully and rigorously executing
plan that turned out to have been utterly flawed.
55. Case Study 3
Online Grocery Store – What Went Wrong??
Question 1: What do you think was the major problem they faced?
Question 2: What type of strategic implementation do they require?
Question 3: What type of work flow was missing in their business idea?
56. 4. Innovative Business Modelling
4.1 Introduction and Relevance
A lot of success stories are based on new business models.
Through the following slides, we help you design your business ideas with these
building blocks, and assist you in finding inspiration from other innovative,
successful and flourishing businesses.
The relevance of using such an innovative approach is straight-forward:
If you can’t draw out your business
plan schematically, you simply don’t
know what your plan is! And hence,
you will never be able to execute it.
57. 4. Innovative Business Modelling

In this activity, you will be provided with basic information of FIVE real-world
startup / established companies.
Using this information, along with the canvas sheets and cue-card cutouts
representing the 6 players and 10 objects of exchange, construct the business
models on canvas sheets.
For this activity you will be divided into FIVE groups and each group will develop
the business models using the information provided.
This activity will require a strong team effort for accomplishment, and ideas
from every individual of the group. Solutions will be shared at the end of the
activity and each business model will be judged accordingly.
