An approach to data, from business need to real-world use

This page explains the context behind the site: how we work and the sharing principles that guide this space around Data, Analytics, BI, applied AI and technologies that are useful in business.

Our perspective

We focus on data where it becomes genuinely useful.

We focus on data when it helps people understand a situation, clarify decision-making, make a process more reliable or support a more coherent course of action.

The subjects explored here sit at the intersection of business challenges, information structuring, analysis, reporting and applied technologies. We pay particular attention to them when they make a solution clearer, more robust and more useful.

We are not interested in figures for their own sake, but in the moment they begin to mean something: when they help structure reality, reveal a gap or turn a still-vague need into an actionable insight.

Method

How we work

We start from the real need, avoid gimmicks and aim to build clear, robust and usable solutions.

01

Clarify before choosing tools

We first seek to understand the need, intended uses and constraints before discussing tools. A good solution often begins with a good reframing of the problem.

02

Structure data properly

We build reliable insights from consistent data, clear indicators and controlled flows. Without that foundation, everything else quickly becomes fragile or difficult to use.

03

Make solutions easy to adopt

We do not consider a solution useful simply because it is technically correct. It must be understandable, usable, explainable and maintainable over time.

04

Connect insight and action

We approach BI, reporting, automation and applied technologies as complementary levers for decision support, decision-making and execution.

Editorial approach

Why this site exists

Use cases Analyses Demonstrations Educational content

This site was not designed as a simple portfolio. We see it instead as a space to work, clarify and share ideas around data.

We bring together use cases, solutions, approaches, analyses and educational content around Data, Analytics, BI, applied AI and the technologies connected to these subjects.

The aim is not to accumulate concepts or abstract demonstrations, but to show how these subjects take shape in the real world: through a business need, a decision-support challenge, a process to strengthen, a flow to structure, a report to improve or a solution to industrialise.

We keep one simple principle: make these subjects more concrete, clearer and more useful, without losing the rigour they require.

Journey

Experience built across business, data and decision-making

This final section looks back at the personal journey that informs the site's editorial direction and the subjects explored here.

My career has developed progressively around one simple thread: connecting demanding business environments with tools for understanding, decision support and improvement.

I first worked in operational and financial contexts, where rigour, information quality and a clear understanding of business constraints are essential. This gave me a practical view of organisations, their flows, controls and real needs.

I then expanded this approach through reporting, data visualisation, data structuring and decision-support work, particularly in finance and insurance. This led me to work on dashboards, indicators, data-quality rules, documentation and reporting.

Over time, my focus broadened to more cross-functional topics across Data, Analytics, BI, automation and applied AI. Today, as a Senior Analytics Consultant at Sopra Steria, I work on challenges that require understanding the business, scoping the need, organising data, building a reliable view and delivering solutions people can actually use.

Portrait de Jérôme Jeannin

I see data as a tool for understanding, but also as a way to drive action. When it is well structured, well understood and well used, it helps us see more clearly, make better decisions and build more coherent solutions. This site follows that logic.
