A simple framework for new (and old) managers to assess their team’s motivation and satisfaction levels.

Over the years I’ve observed a fundamental flaw in the workplace — There is zero support for new managers to develop the skills needed to effectively manage a team. Companies often promote great people into management positions but seem to overlook the fact that the promotion came as a result of doing great work as an individual contributor, not as a manager. This was true for me and I know it’s true for many new managers I’ve worked with. …


Thanks for sharing this post Lukas. It's quite frankly one of the best posts I've ever come across on Medium. Well articulated, honest and inspiring. All the best on your new adventure.


5 skills to look for in potential candidates

A follow-up to my previous post — “Why Product Analytics is more important now than ever before”.

There has recently been a growth in companies looking to hire Product Analysts. I’ve even advised a few Product leaders over the past few months on what to look for when hiring. So I thought I would take some time to write and share the skills I look for when interviewing potential candidates for a Product Analyst role.

Although each candidate is unique, I’ve found that assessing the following 5 areas can give you a like for like pyramid style framework to fairly…


and why you need to be investing in it

I believe Product Analytics will be the next big thing in the data space. It might not reach the dizzying heights of Data Science and I doubt it will ever get a sexiest job of the 21st century article published about it on Harvard Business Review (HBR) but I’m certain it will make an equally impactful contribution to any company that invests in it.

Product-Led Growth (PLG)

Product-led growth is a relatively new concept coined by Open View Partners who describe it with the following definition:

Product led growth (PLG) is an end user-focused growth model that relies on the product itself as…


Making MDE the subject of the equation

In part 1, I discussed why we need to move away from MDE as an input variable to an output variable and make it a function of the available sample size. In this post, I’ll share what the rearranged formula looks like, along with a hacky Microsoft Excel solution.

As a reminder, these are the formulas for sample size where:

- α: the selected level of significance
- β: the selected power
- σ: the standard deviation
- μ1 or p1: the baseline mean or proportion
- μ2 or p2: the proposed/expected new mean or proportion
(this is where our MDE currently sits)
- r…


Moving MDE from an input to an output

The Minimum Detectable Effect or MDE has always baffled me, and not because it’s a difficult concept to understand but rather because most people working in the field of experimentation have been using it counter-intuitively for so long.
For the record, I don’t think any of what I’m about to write is groundbreaking, but having worked in this field for many years, I’ve not seen anyone talk about it so I thought I would. Who knows, maybe you’ll disagree with me.

How are people currently using MDE?

The MDE is one of several inputs used to calculate the sample size required for an experiment along with:


A poem about AB Testing

Sometimes we’re normal
Symmetrical around Mu
But like yin and yang,
Positive to negative
Sometimes we skew

Like a null hypothesis
you love to reject me.
And all because you believe,
That we’re just an example
Of two different samples
From two different populations,
But if we put aside our differences
We can create a better hypothesis

You’re seeing things
That just don’t exist
But the things that are real
You continue to miss.
This isn’t a mistake
Just look in the mirror
What you’re seeing is random
It’s a type 1 error

You say I’m needy,
I’d say I’m dependent
Your…


It’s nice when everyone is in agreement about something. It’s even nicer when that agreement is around your way of thinking. But let’s face it, if everyone agreed with each other all the time, the world would be a pretty boring place.

Our uniqueness, whilst making us special, can often lead to conflict at work and we regularly find ourselves in situations where we’re going head to head with people because we don’t share their views and they don’t share ours.

These head to head battles of differing opinions are exhausting and if you regularly find yourself in them, either…


Things I’ve learnt and mistakes I’ve made

As we say goodbye to what has been quite possibly the most demanding year of our lives, well at least my life, I wanted to share a few things I’ve learnt as well as some mistakes I’ve made along the way when starting in my new role. I joined Gousto back in May 2020, during the middle of the first lockdown, and whilst the onboarding process was seamless, the experience was anything but. Don’t get me wrong, it was never going to be easy as I was building a new team and function…


This is quite possibly the easiest blog post I’ve ever written as well as my all-time favourite. Last night we had a virtual data team Christmas party where we played many games, one of which was a drawing competition where we had to draw a Christmas themed picture on Paint.

Now drawing anything on a computer usually requires a very special set of skills, software and equipment… none of which you’ll find within a team of data professionals, which is what made the outcome even better.

Although the drawings below look like they were made by a class of 7-year-olds…
