Innovation Kpi – One Lean Startup Experiment Per Week

Innovation kpi by Tristan Kromer

“Go fast” is one of the principles of running a lean startup experiment. The faster we go around the Build-Measure-Learn loop, the faster we validate our business model the sooner we have a business.

(Note: To be accurate, we’re not validating our business model, we’re successfully failing to invalidate it. Correction thanks to Roger Cauvin.)

So how fast is fast enough?

Many teams wonder if they’re moving fast enough. Many accelerator managers and VPs of innovation kpi worry if their teams are running enough experiments or doing enough research. What’s normal?

tl;dr: We should target at least one experiment/research per week- innovation kpi.

Knowledge Velocity

Build Measure Learn - the basis for a lean startup experiments

In this context, speed refers, not to our ability to produce code or products, but to our ability to learn.

The output of the Build-Measure-Learn loop is knowledge. Click To Tweet

We should ideally measure the amount of knowledge coming in and not all knowledge is equal.

Figuring out which of the 41 shades of blue convert best sounds like a lot of experiments- innovation kpi, but is that a lot of knowledge? Wouldn’t one experiment that determines if someone is willing to pay for your product be better?


In agile, stories (think of them like tasks if you’re not familiar with agile) are often weighted by difficulty, time estimate or some other method like planning poker. While this seems like a great idea in theory and VPs of innovation love this metric, it’s excessive.

Edit: David Bland pointed out we may not be direct enough here. So we’ll say it more clearly,

Assigning knowledge points to experiments is a terrible idea. cc @davidjbland Click To Tweet

Measuring knowledge output sounds important when comparing one team to another or trying to measure the overall knowledge output of 20-100 different teams. However, from the perspective of one team, it’s irrelevant. Here’s two reasons why:

It’s All Relative

We can generally only run 1-2 experiments at the same time, not 20. So it makes no difference how many “knowledge points” that experiment is worth.

Only one question matters: Are we working on the most critical business risk? Click To Tweet

Stack ranking priorities for running a lean startup experimentIf we simply stack rank our assumptions in terms of risk, we should clearly work on the top one! The point value is irrelevant.

We could spend time assigning point values and submitting reports that can’t be realistically compared with risks from a completely different project. Then the VP of Innovation can start discounting point values based on the relative complexity of the business models, but that time is better spent actually doing work.

The only relevant question is, are we working on the most critical business risk?

The answer is binary, yes or no.

Knowledge Velocity Should Slow Down

In fact, if the team is doing really well and the project is progressing, the knowledge velocity should be getting lower over time.

Why? Because we’ve learned all the important things! The Business Model is solid!

It’s now about optimizing all the little details. So the amount of knowledge we gain each week should be getting smaller and smaller.Knowledge to Assumption Ratio to Time

In other words, our knowledge to assumption ratio (as Dan Toma is calculating it) should be approaching 1. (At least until the business environment changes or is disrupted, at which point out ratio is probably back to zero.)

Lean Startup Experiment Benchmark – One Per Week

Business Model Canvas by Alexander OsterwalderSo instead of trying to precisely measuring the number of points of knowledge produced each week, we should just measure our experimental/research velocity. It’s not ideal, but it’s a way of asking, “Are we learning anything about our business model each week/innovation kpi?”

Benchmarks are tough. A B2B direct sales team would reasonably argue that they will have a slower velocity than a SaaS consumer product which can A/B test their landing page every day.

True. There are hundreds of good reasons why different teams in different verticals with different business models will have different velocities.

But let’s put a stake in the ground and say that

At least one experiment/research per week is a lean startup benchmark. Click To Tweet

We will no doubt get hate mail for saying this. “It’s too fast!” “It’s too slow” but here’s why:


Firstly, one lean startup experiment per week is achievable for any team in any context.

There will be those teams that say it’s impossible because they have to build really complicated things or their sales cycle is too long.


It will take a long time to build!

Minimum Viable Product - Marshmellow toasterMost likely, we probably don’t need to build it. Concierge test it, rig the backend with Mechanical Turk and Wizard of Oz test it, did we remember to smoke test it first? There’s always some test that some team members can do while the basic infrastructure is being done.

If it’s truly impossible to run one experiment per week, there is another obstacle in play and it’s most likely an incomplete team or a bureaucracy problem.

Our sales cycle is too long!

This is an identical excuse. Instead of measuring the entire six month sales cycle, we could measure the number of meetings we can set up based on our initial value proposition or even the open rate on our emails. There is a way to run research or an experiment this week.

If one experiment per week sounds like too much, we're doing it wrong. Click To Tweet

Measure but Don’t Count

An Abacus for Innovation Accounting“At least” is a key part of the benchmark. It means that zero experiments is failure, but 3 lean startup experiments per week are not necessarily better than 2.

This is because “you get what you measure.” As human beings, we’re very good at optimizing for arbitrary metrics. So if we’re forced to count lean startup experiment velocity, it’s pretty much guaranteed that we’ll game the system and run as many teeny tiny experiments as possible.

Then we’re just back to testing 41 shades of blue without tackling our truly risky business assumptions.

Our experience with teams from early stage to enterprise and Japan to Switzerland has been that by setting a benchmark of at least one experiment/research method per week, teams often rake up two, three or more. Setting a fixed goal of ever increasing numbers of experiments tends to lead to smaller and smaller goals or arguments about the validity of the knowledge produced.

(If you have a different experience, we’d like to hear about it. Tweet us.)

Setting a fail condition rather than asking teams to run as many experiments as possible prevents teams from optimizing for number of experiments rather than making genuine business progress. In this way, we measure what matters, but don’t count the number of experiments arbitrarily.

It becomes binary, “Are we learning?” Yes or no.

Setting a fail condition is also good habit.

The Habit of Lean Startup

At least one experiment per week also helps set up a habit. It allows us to have a regular cadence where we can have our sprint planning session, our retro, etc, at the same time every week.

The Hooked Model by Nir Eyal, useful for thinking about building a habit for Lean Startup MethodologyEvery other week and it’s ever so slightly harder to build a habit associated with a particular trigger. In this case, the trigger is a day of the week. It’s why we have “casual Fridays” and “Taco Tuesdays.” We don’t have “bi-weekly Taco Tuesdays.”

Personally, if I don’t have my retro and backlog grooming on Friday, it means my brain is going to churn all weekend and I won’t be refreshed for the week ahead. That’s a good thing.

It means I have an internal motivation and trigger for getting my experiments done. It’s a very satisfying feeling seeing all those Trello cards go in the archive.

Of course, feeling satisfied is hardly a scientific metric, but we’re humans, not robots. (At least for a while longer.)

So we can still ask, “Do we feel we made progress last week?” Yes or no.


Sloth - Sometimes your corporate startup bears some similarities

If you have the momentum of a sloth, going 1 mph would be a huge improvement.

While the benchmark of innovation kpi- one lean startup experiment / research per week has been consistently achievable by almost every team we’ve worked with, there is one other consideration: Momentum.

How fast were we going before?

Ultimately, lean startup is about continuous improvement. If our previous velocity was one lean startup experiment per year, then running one per month isn’t too bad.

It’s still not great, but it’s better. So before beating ourselves up too badly, we should just ask, “Are we learning faster?”

If yes…high five and keep going.

Team Checklist

To see how we’re doing we can ask these questions each week:

  • Are we working on the most critical business risk?
  • Did we run a lean startup experiment or research project?
  • Do we feel like we’re making progress?
  • Are we learning faster?

Or to put it into commandments, each week we should:

  • Prioritize
  • Learn something new
  • Build good habits
  • Continuously improve

    Love the one test/week as a minimum.

    Testing is probably the most overlooked aspect of lean startup. Designers have been interviewing customers and creating prototypes for years.

    What Lean Startup really introduced is testing in a product context. If you aren’t completing tests and interpreting test results, you’re not really doing Lean Startup.

    1. Tristan says:

      Totally agree. Nothing is really new, but the application of research/experimentation is still in it’s infancy.

    1. Tristan says:

      Definitely a great saying.

  2. Andrew says:

    Hey, could we maybe go through some example experiments across a various industries?

    1. Tristan says:

      I’d love to. I think Eric’s new book will get a lot of examples out there. A lot of the work I do is in the tech sector so I don’t get a huge amount of diversity and most of it is under NDA so I can’t write explicitly about it.

      I can try and post about some of my experiments directly if they are pertinent. What industry are you in?

  3. Roger L. Cauvin says:

    Setting a goal and cadence for experiments is a good idea if just to get past the inertia that many teams have in this area. They want to make “progress” but don’t naturally think of each unit of progress as a test.

    I also like the team checklist.

    As for

    “The faster we can go around the Build-Measure-Learn loop, the faster we validate our business model.”

    Yuck. We never validate it. We iterate to one that survives our attempts to falsify it.

    1. Tristan says:

      You are correct! My bad. Going in for an edit now.

    2. Tristan says:

      Dang…there is no easy way to write that sentence so it is succinct and accurate.

      1. Roger L. Cauvin says:

        How about:

        “The faster we can go around the Build-Measure-Learn loop, the faster we move towards a business model that works.”

        1. Tristan says:

          I went one further: The faster we go around the Build-Measure-Learn loop, the sooner we have a business.

          1. Roger L. Cauvin says:

            Great summary of how Karl Popper eventually came to treat the matter of truth and falsity:

            “Popper eventually realized that this naive falsificationism is compatible with optimism provided we have an acceptable notion of verisimilitude (or truthlikeness). If some false hypotheses are closer to the truth than others, if verisimilitude admits of degrees, then the history of inquiry may well turn out to be one of progress towards the goal of truth. Moreover, it may be reasonable, on the basis of the evidence, to conjecture that our theories are indeed making such progress even though we know they are all false, or highly likely to be false.”

    I love this post – Reid Hoffman has been talking about blitzscaling recently… I think the counterweight to that is blitzlearning. Hearing Steve Blank ask the teams at StartupIstanbul last week “What did you learn” vs something about the potential size of their unknown market, or even where their team went to college, was incredible and I think it is the way all new ideas and teams should be evaluated from now on:)

    1. Tristan says:

      Thanks Adam, I wish I’d been able to make Steve’s talk. I packed my Istanbul schedule a bit heavy!
