Data Science Methodology

a Data Science Methodology structures your project

Getting insights out of the data, that’s what it’s all about in data science. After we have defined the business goal you try to solve, our data scientists jump in, try to get the data & start their process.

element61 has build its own Data Sciency Methodology in line with the CRISP DM framework. This methodology is in-depth variant of our element61 methodology elementary specific to Data Science.


Our Methodology

We adhere to a standard Data Science Methodology including the following steps:

Data Science Methodology


  • Strategy

It's important to us to understand the context & objectives of your project. What business problem are we trying to solve, what has been tried in the past, etc. Additionally we need to understand what the ambition is: what do we expect from the Machine Learning solution, who will use it & how frequently, how will actionable results be implemented in the existing business processes. Through a series of workshops we define & document this strategy as a project outline.
  • Data Gathering

We translate the business problem at hand into data & identify the right data sources & fields. We sit with the BI & data teams & jointly define the extraction and load methods we can leverage to get access to the data.

  • Data Discovery

Before building the model, we spend sufficient time on Data Discovery or running various discovery analyses to challenge or confirm initial hypothesis. We get to know the data, iteratively provide feedback & thus crystalize the case at hand of what we want to predict & how we can best do it. 

  • Machine Learning

In this phase the actual modeling takes place. Our Data Scientists do feature definitions based on our disovery analyses and run & compare different predictive models, evaluate their performance, finetune and rerun. This is an iterative process where we iteratively communicate feedback & performance back to the client.

  • Fine Tune & testing

The model needs to be relevant & actionable. Therefore, we set-up a fine-tune phase where we go, with the business, through the results & where possible even set-up a real-live test. Furthermore, we help you to embed the resulting model within your business processes so you can fully leverage the newly created model. Every Proof of Concept delivered by our team results in an actionable working process which can be leveraged for a set of weeks of months providing real added value.

How we use it

All our proposal & projects are build around this methodology.
Based on our experience, this methodology is giving us a structure to tackle a problem step-by-step & to deliver, at every stage of the project, clarification and alignment to the project team.
