Course summary

During this two-day validation crash course we will show you how to make innovation actionable, by taking you through the entire validation process. We will start with the assumption and what it entails. You will learn to identify it, rank it and translate it to a hypothesis. You will become a master at going from a hypothesis to an experiment plus designing and executing that experiment afterwards.

Key learnings

Choosing a focus

It is imperative to focus on what’s important: the problem. What is the problem that you are solving? Which are the customer pains that you are relieving? This creates value.

From assumption to hypothesis to experiment

Using the desirability, viability and feasibility lens allows you to create assumptions from your ideas, which you will then rank based on risk. The riskiest assumption will be translated into a hypothesis, a measurable statement and eventually, an experimental outcome.

Running SCRUMs & sprints

Running scrums (not the rugby ones) allows you to break up large projects into smaller, stand-alone tasks that each have value for the customer. This means working in two-week sprints with deliverables at the end of each sprint.

Experiment Stacking

See the value in stringing together multiple experiments instead of one. We believe that business decisions can’t be made based on one, lonely experiment. It’s the sequence of experiments that gives us the confidence to say that a hypothesis is validated. Confidence is key!

No-code toolstack

No code tools allow us to focus on testing our MVP instead of building it. It’s perfect for validating critical assumptions and discovering what your audience really wants. It’s our codeword for faster validation.

What participants say about us

Good combination of theory & practice. Nice to work on several concrete ideas and to spar with "like-minded peers". Applying theory hands-on to concrete topics. Highly recommended!
Toon Torfs
—Innovation, Business Development & Sustainability at Schoenen Torfs
Very satisfied because the theoretical presentation was followed by an example (in group) in practice so your knowledge sticks for future projects. Cosmos was great at working out cases, in their interaction & communication, explanation of examples from own experiences and in providing a mixture of participants & branches.
Amelie Withaeckx
—Project manager Business Development & Innovation at Solucious
Hanne and Frederik guided us through the up to then “experiment’s maze” with mastery. By sharing their extensive experience & applying the theory on the spot, I have learned how powerful and important an experiment setup is. The most significant learning for me was how to tie up different experiments, as the sequence of experiments gives us the confidence to say that a hypothesis is validated.
Daniel Bastos
—Transition Management and Ways of Working at Nike
I am a big proponent of learning hands-on. They have perfectly combined this with theory and provided interesting tools. You are never alone in the exercises. There is always someone ready to help you back on your way. A very instructive masterclass that creates a safe space for all your questions and comments.

Frequently Asked Questions

In case some things weren’t clear

Growth takes the traditional marketing model and adds layers such as A/B testing, value-additive blog posts, data-driven email marketing campaigns, SEO optimisation, creative ad copy and technical analysis of every aspect of a user’s experience. The insights gained from these strategies are quickly implemented in order to achieve robust and sustainable growth.

Validation starts with the idea or innovation challenge, which is then dissected based on the 3 innovation lenses: Desirability, viability and feasibility. Dissecting means creating assumptions from the idea, which are then ranked based on risk. The riskiest assumption is then translated into a hypothesis, a measurable statement and an experimental outcome. It is the process of going from an idea, all the way to an experiment to validate or invalidate the hypothesis that came out of your idea.

This training is relevant for you:

  • if you’re an entrepreneur wanting to validate & launch a new business idea. 
  • if you’re an innovation employee / intrapreneur that needs to make new ideas possible and tangible.
