Innovation Methods: What Type of Lean Startup Experiment Should I Run?

Picnic in the Graveyard

How do we run lean startup experiments for continuous innovation methods?

When I was studying marketing I had an arms length list of research techniques like conjoint analysis, surveys, and focus groups. After I read Four Steps to the Epiphany, there was only one: Get out of the building and talk to customers!

At LUXr, Janice Fraser introduced me to a whole new host of tools to gain insight such as hallway usability testing, contextual inquiry, and mental models.

Add this to lean startup standards like smoke tests and the list gets pretty overwhelming.

Should we run a Pocket Test with Picnic in the Graveyard to follow up? Should we do a Wizard of Oz or a concierge approach? Would you like a lemon twist with that?

So what type of experiment should you run for innovation methods? And when?

If you’d like to cut to the chase, you can download the list and index here:


Qualitative vs. Quantitative


Qualitative vs. Quantitative

Many, many people have weighed in on which is superior.

Ash Maurya recommends using qualitative research and then validating it with quantitative. Laura Klein’s post When to Listen & When to Measure does the battle the most justice.

As Laura points out in her post, it’s not a question of better. A hammer is not inherently better than a screwdriver. A hammer is better than a screwdriver for hammering in nails.

Generative vs. Evaluative

Generative Research vs. Evaluative Experiments

Janice Fraser introduced me to the distinction of Generative vs. Evaluative techniques for innovation methods:

  • Generative – Research techniques which don’t necessarily start with a hypothesis, but result in many new ideas. e.g. Customer Discovery Interviews
  • Evaluative – Testing a specific hypothesis to get a clear yes or no result. e.g. Landing Page a.k.a Smoke tests

This distinction explains why we often get crappy results from experiments conducted for innovation methods. We might run a smoke test with the hypothesis:

Some people will sign up to a “coming soon” landing page featuring 100% compostable shoes.

We advertise via twitter and come back with a paltry 1% conversion rate to email sign up. Good idea? Bad idea? We confirmed our hypothesis…”some people” did indeed sign up!

But is our conversion rate low because no one is interested? Or because we advertised via the wrong channel?

Does no one want our value proposition? Or does no one understand it?

There are a hundred reasons why we might get a false negative result from this test. There are also quite a few reasons why we might get a false positive!

It's difficult to interpret tests because often the hypothesis is fundamentally flawed or just vague. Click To Tweet

In this case our hypothesis is incredibly vague and flawed.

Some people will sign up to a “coming soon” landing page featuring 100% compostable shoes.

Who are these people? People on twitter? Who are they following? Are they eco-friendly dads who bike to work? Or are they professional runners who care more about durability than being environmentally friendly?

When our hypothesis is specific and falsifiable, we can run an Evaluative Experiment such as a smoke test.

When our hypothesis is vague or we don’t even have a hypothesis, we need to do Generative Research such as getting out of the building and talking to potential customers to get new ideas or refine our hypothesis.

Market vs. Product

Market vs. Product

The other obvious distinction among tools and methods in the Real Startup Book is between Market and Product.

Some methods tell us a lot about customers, their problems, and how to reach them. For example, we can talk listen to our customers and this will help us understand their situation and what their day to day problems are.

Other methods tell us about the product or solution that will help solve that problem. We can do usability testing on a set of wireframes and see if our interface is usable. However, this won’t tell us anything about whether or not anyone will buy it in the first place.

These methods generally don’t overlap.

What type of lean startup experiment should I run?

If we combine the useful distinctions of Generative Research vs. Evaluative Experiments and Market vs. Product we have four nice boxes which we can use to help us determine what we should do next to optimize the innovation methods:

The Lean Startup Playbook - Which test should I run next?

Each of these boxes helps us answer different questions.

Generative Market Research

Generative Market Research for innovation methods

  • Who is our customer?
  • What are their pains?
  • What job needs to be done?
  • Is our customer segment too broad?
  • How do we find them?

If we can’t answer these questions yet, we’re doing what Steve Blank would call Customer Discovery (The first Step to the Epiphany.) We need to to understand the basis of the problem before testing a solution. If we’re not sure what our hypothesis is, we need to generate ideas.

We could talk to customers and see what’s bothering them (Steve’s advice and always a good idea) or we might try data mining if we happen to have access to a large set of data. We could even do a broad survey with open ended questions.*

Some of these research methods are qualititative (e.g. talking listening to customers) and some are quantitative (e.g. data mining). That distinction is not important.

Data mining is quantitative but helped identify problems such as food deserts in the United States. We couldn’t have done that by talking listening to customers! Both tools can discover problems.

Here are some of  Generative Market Research methods:

  • Customer Discovery Interviews
  • Contextual inquiry / ethnography
  • Data mining
  • Focus groups*
  • Surveys* (open ended)

* Don’t do this. Surveys and focus groups generally suck.

Evaluative Market Experiments

Lean Startup Playbook - Evaluative Market Experiment

  • Are they really willing to pay?
  • How much will they pay?
  • How do we convince them to buy?
  • How much will it cost to sell?
  • Can we scale marketing?

To evaluate a specific hypothesis, we might run a landing page test to see if there is demand. We might run a sales pitch if you were doing B2B enterprise product. We could even run a conjoint analysis to understand the relative positioning of a few value propositions.

Here are a few Evaluative Market Experiments to discover innovation methods, if we have a clear, falsifiable hypothesis:

  • 5 second tests
  • Comprehension – link to tool
  • Conjoint Analysis
  • Data mining / market research
  • Surveys* (closed)
  • Smoke tests
    • Video
    • Landing page
    • Sales pitch
    • Pre-sales
    • Flyers
    • Pocket test
    • Event
    • Fake door
    • High bar

* Again, don’t use these. They generally suck.

Warning: Here be False Positives

Customer Development Survey False Positive - Survey.ioBefore we move on from here, we must remember: we’re probably wrong. Even if we have tens of thousands of users signed up to our landing page, that doesn’t mean we have a validated problem.

If the customer didn’t have to commit to anything aside from their email address or they misunderstood the value proposition, then those signups don’t signify true customer demand. It just means we make awesome landing pages.


Our Value Proposition is not our product. Click To Tweet The Value Proposition is the benefit that the product delivers to that specific customer. Click To Tweet We cannot have a validated value proposition without a validated customer segment. Click To Tweet

Generative Product Research

Lean Startup Playbook - Generative Product Research

  • How can we solve this problem?
  • What form should this take?
  • How important is the design?
  • What’s the quickest solution?
  • What is the minimum feature set?
  • How should we prioritize?

Once we’ve validated the market and value proposition sufficiently, we need to understand what the solution would look like.

If we truly have a validated Customer with a clear Problem and a Value Proposition, then we can start asking how.

Unfortunately, while our market hypotheses tend to be overly vague, our solution hypotheses tend to be overly specific and way too comprehensive.

The 20 features that are absolutely critical to a comprehensive solution, often turn out to be distracting and confusing to the user. Click To Tweet

To simplify our solution and help us prioritize which features to build first, we can use methods like concierge testing or solution interviews to help us generate ideas about what our MVP should be.

Here are some methods for Generative Product Research:

  • Solution interview
  • Contextual inquiry / ethnography
  • Demo pitch
  • Concierge test / Consulting
  • Competitor Usability
  • Picnic in the Graveyard

Evaluative Product Experiments

Lean Startup Playbook - Evaluative Product Experiment for innovation methods

  • Is this solution working?
  • Are people using it?
  • Which solution is better?
  • How should we optimize this?
  • What do people like / dislike?
  • Why do they do that?
We probably started off with a clear idea of the product. It's probably wrong. Click To Tweet

Fortunately, there are a list of well defined tools that have been around for decades to figure that out.

We can do user testing to look for usability issues that might prevent the solution from working. We can A/B test two alternatives to see what works better. We can use a Net Promoter Score survey (one of the few surveys that I like) to see overall satisfaction. All of these Evaluative Product Experiments tell us if our solution is doing the trick.

  • Paper prototypes
  • Clickable prototypes
  • Usability
  • Hallway
  • Live
  • Remote
  • Wizard of Oz
  • Takeaway
  • Functioning products
  • Analytics / Dashboards
  • Surveys*
    • Net Promoter Score
    • Product/Market Fit Survey

* These aren’t quite as bad as most surveys, but be sure you understand them before you use them to measure Product / Market Fit.

The Real Startup Book

The Lean Startup Playbook - Which test should I run next for innovation methods?One last tip: The Real Startup Book is an arbitrary framework.

Any idiot with an MBA knows how to make a 2×2 grid that will look impressive in a powerpoint when doing a consulting gig. That doesn’t mean reality fits neatly into those boxes.

A lot of research/experiments will blur the lines. It’s rare that we’ll do generative research without having a hypothesis in the back of our mind about who our customer is. We may inadvertently evaluate (and invalidate) that hypothesis. That’s ok.

This is just a framework to get ourselves headed in the right direction and make it more likely that we use the right tool for the job.

    Very thought provoking synthesis of a methodology for selecting the right market exploration approach.

    1. Tristan says:

      Thanks Sean! I’ve been using it for the last year in my workshops. (But without the snazzy illustrations.)

  2. David Stengle says:

    This is wonderful. The art fits nicely. I think the heuristics side is often neglected. Sean said it better, but the content compels me to express my appreciation.

    1. Tristan says:

      Thank you very much David! I probably spend more time on the drawings than I should, but I enjoy it quite a lot as a break from work. (Plus I now have two coconspirators who can help me with artwork when I flail.)

  3. Josh Furnas says:

    This is currently my favorite way to start experiments. Categorizing them into one of the four quadrants helps me then focus the construction of the hypothesis / learning goals. With experimentation I think a lot of it has to do with creating and sticking to that defined scope.

    Too often I see “well what if we could also attempt this at the same time” and the experiment starts mixing quadrants. Then you get a lot of unfocused shallow feedback and to little specific, deep, and meaningful. Great stuff.

    I had previously thought of Qualitative/quantitative as synonymous with Generative/Evaluative but I see you’ve broken up the definitions well.

    I’m curious what type’s of useful Qualitative tests can be Evaluative and Quantitative tests Generative?

    1. Tristan says:

      Great point!

      Data mining or surveys are examples of quantitative generative research methods. Although I’m not a fan of surveys, we can imagine a survey like “How often have you missed your mortgage payments in the last 2 years?”

      The quantitative result might indicate a problem worth talking to respondent about.

      A five second test or comprehension test are great examples of qualitative evaluative tests. A B2B sales pitch (under smoke test) is the most common qualitative test of market demand.

    Tristan, you wrote:

    “If we can’t answer these questions yet, we’re doing what Steve Blank would call Customer Discovery (The first Step to the Epiphany.) We need to to understand the basis of the problem before testing a solution. If we’re not sure what our hypothesis is, we need to generate ideas.”

    The implication is that Blank’s customer discovery can include the process of generating ideas and insights through talking to customers, before having any sort well-formulated hypotheses.

    I always shared this view until I paid closer attention to what Steve Blank actually says:

    You’ll note that, for Blank, customer discovery seems to start with concretely documenting your hypotheses and then testing them. There is no purely generative component.

    In a comment on Blank’s blog entry, I asked whether customer discovery can include discovering insights without prior formulations of hypotheses. Blank did not answer the question in the comments, but his next blog entry seemed to be a response:

    You’ll see in that blog entry he states the customer development process is for startups that already have a product or product idea and “now need to find customers and markets”. He implies that design thinking is for generating insights, and that it’s not practical for startups to engage in that sort of activity.

    I was perplexed to see and hear these views from Blank.

    1. Tristan says:

      I’d have to agree with you there. I find that very perplexing.

      Ideas come from somewhere, often from “accidental ethnography” (a.k.a contextual inquiry) where an entrepreneur might experience or see a problem and then go decide to solve it. That’s what I would call generative research and we’re doing it all the time as human beings.

      I find that the “hypotheses” that most entrepreneurs put down on their business model canvas are just vague generalizations and assumptions. They are not specific enough to be considered hypotheses and often take the form of a tautology such as “The customers for my radical new potato peeler are people who peel potatoes and are dissatisfied with the current potato peeler industry.”

      Hence my inclusion of narrowing ideas down and getting concrete into generative research.

      So I suppose I could be misinterpreting Steve Blank, but if so, I might then have to disagree with him. Listening to customers, getting out of the building, and data mining are great ways to find problems to solve and to discover a market, even before you have an idea for a product.

      If you see him, ask him!

    2. Sean Murphy says:

      I find Steve educational reading when he talks about mistakes he has made or when he interviews other entrepreneurs talking about lessons learned. But I don’t find him as useful for prescriptive insights, which is what you are asking for. The fact he does not find design thinking and ethnographic methods useful does not mean they are not not useful. Many other entrepreneurs have found them very useful.

      In this older blog post about his actual experience seems to indicate he did customer interviews with an open mind: I blogged about this at

      1. Roger L. Cauvin says:

        Thanks, Sean. I really like the content and both of the links you shared.

        What Blank describes in his piece is what I’ve always considered “customer discovery and development”. He did mention he formed hypotheses before talking to prospects, but the questions in his “survey” were open-ended enough to gain some insights into “unknown unknowns”.

        While I think forming hypotheses, even in very early stages before a system effort to talk to customers, is a best practice, I also think it’s important to be careful not to let those preconceived hypotheses bias the questions to being too directed.

    Great post and interesting book! Innovation is a completely unpredictable thing. Many ideas that appear obvious to us may get simply disproved if we experiment them. It’s important not to underestimate the power of experimentation. The results can shock us some time. We have written an article covering a similar topic and would be happy to have your feedback! 🙂
