Generate more accurate forecasts
in less than 4 weeks

(without being a mathematician or IT expert)

How is your forecasting situation today?

Are your sales forecast all over the place? Are you drowning in unsold stock? Do you feel every department in your company operates in its own universe? It’s time to face the harsh realities 👇
  • Demand Uncertainty: Interest rates variations, inflation, geopolitical conflicts… The uncertainty impacts global demand, making your forecast inaccurate.

  • Data issues: You are lacking data (or wrestling with inaccurate data), turning every forecasting attempt into a high-stakes gamble.

  • Rigid Software/ERP: Ever tried generating a quick report and ended up spending hours navigating through unintuitive menus? That’s your ERP system—more of a hindrance than a help.

  • No team alignment: To make matters worse, your team is completely misaligned. The sales, Marketing, Manufacturing departments are operating on different planets. If there is an S&OP (Sales and Operations Planning) it is at best wilingful but mostly inefficient.

  • Not enough time: As if that’s not enough, you’re swamped with endless meetings and a never-empty inbox, leaving you no time to focus on forecasting

The Costs of Inaccurate Forecast

Time & Stress: The “Firefighter syndrome”

You likely know the strain that comes from bad forecasting. It hits everyone, from the boardroom to the warehouse. When predictions fail, your team rushes to handle emergencies instead of focusing on big-picture tasks. Constantly being in crisis mode isn’t just a bad strategy; it’s a fast track to stress and burnout.

Career Stagnation

For those in managerial roles, bad forecasts mean bad performance reviews and stalled career paths. For anyone making forecast, a lack of accuracy becomes a direct impediment to promotions and professional growth.

Profit & Inventory rollercoasters

Bad forecasting results in allocating the wrong ressources at the wrong time: Investment, Cash, Recruitment, Marketing spend and either excessive or insufficient inventory. Both scenarios are damaging: stockouts lead to lower revenue and customer discontent, while surplus inventory escalates holding costs. Overall, it results in diminished cash availability and reduced profits for your organization.

Environmental Impact

Inaccurate forecasts mean Last-minute adjustments—rush orders, expedited shipping… The result? Increased operational costs and, even worse—an increased carbon footprint, waste and too much impact on our beautiful planet.

The 5 wrong solutions to improve your accuracy

Hoping for demand to stabilize

Volatility got much worse since the last pandemic and global uncertainty is here to stay. There is no stable industry with perfect steady demand. We have to become more resilient and proactive.

Waiting for the new version of your ERP/Software

You may wait another 1 to 5 years...if your project get approved. Not even sure, it's gonna be easier for you after. Believe it or not, you don't need a state-of-the-art ERP or forecasting tool to succeed. I've managed erratic demands for major retail clients like Decathlon and Coty using just Excel

Seeking perfect data

Some hesitate to dive into forecasting because they believe they need a mountain of 100% clean data to start. The truth is, even a few years of historical sales data can provide a solid foundation for your forecasting journey..

Starting a new degree in Mathematics & Data Science

You might fear that you need to be a mathematician or a machine learning expert to forecast effectively. In reality, even renowned forecasting competitions have shown that basic statistical methods are just slightly less accurate than AI powered algorithms (and are more than enough for 99% of the companies)

Relying on your Management for Solutions

Your superiors are probably like you, very busy. If they haven't already provided you with the right solutions and methods, they are unlikely to do so later.

How to improve your forecasting accuracy quickly

1. Focus on what you can impact

At the global and industry level
, The demand uncertainty is influenced by macroeconomic factors: there is little you can do about it simply because you can not change world.

At the level of your company, better forecasting is theoretically achievable through better organization, better recruitment, better software etc. But again, you have little control over it -unless you are the CEO. (Many CEO can’t even have fast impact on large organization)

Instead of waiting years for a more settled Demand, a better Company Culture or a new ERP Software, focus on what you can impact: Yourself and your team.

2. Assess your forecast maturity


In my forecasting journey, I have designed very simple forecasting process and models but also complex ones: I collaborated with the MIT for 3 years, running models on eight different supercomputers for months.

The verdict?

We often believe that complexity equates to accuracy. But in reality, it’s an 20/80 game – sometimes simplicity is the ultimate sophistication.

I remember than adding so much external parameters to my forecasting algorithms (such as the influence weather on demand etc.) were causing them to be overreactive and provide worse results than super simple models.

That’s why the level of complexity of your forecasting process and models must match the level of your forecast maturity.

Otherwise you will face a performance “crash” .

3. Start immediately with simple action & tools

I asked 389 professionals on Linkedin about the tool they use to forecast 👇

27% use a ERP & Forecasting Software: If it is your case, you might be frustrated by the lack of flexibility of those tools, that weakens both your forecasting process and model.

Then start implementing models in Excel. The big advantage of Excel is that you can test quickly and practice by yourself to upskill.

But a majority of you are already using it (62% of the respondents) and are not yielding results. Then you might not have the right methodology.

The most straightforward approach is to follow 8-steps -from defining your goals to empower your team.

This method made me achieve better forecasting, become a top performer and regain control of my time. More on that method below.

How Mario and I became Top Performers

Mario has been a close friend for 12 years. We met while working at Decathlon in Supply Chain and Finance.

As we were traveling the world for our jobs, we had lively debates about the best way to work: more efficiently, more automatically, more innovately.

We have been top performers in our forecasting careers partly because we were highly proactive and pragmatic.

We co-created a complete method called Forecasting Expert™ that combines our 2 different approaches and styles 👇

In general, the program is for any profesional managing demand/sales forecast.

Solo Formula:

  • Managers/ Directors/ Executives who need to quickly get to the point to manage their teams
  • Consultants who need concrete tools and methods to meet their clients’ expectations
  • Entrepreneurs who want to achieve fast and lasting results by following a simple method.
  • Students and job seekers wishing to boost their skill and attractivity.

Teams Formula:

  • Managers/ Directors/ Executives who need to train their teams in no time
  • Entrepreneurs looking to boost their company’s performance
  • HR and training managers wanting a tailored solution to ensure a certified upskilling of their teams

The program only opens for a few days each year to ensure quality follow-up with members and to prepare for future updates.

When the program opens, you can join on the day and not start the program for several weeks or months. Start at your own pace. However, I recommend that you devote at least 30 minutes a week to the program to get quick results.

You don’t need to have a background in demand/sales forecasting (nor statistics or data science). This method is holistic and doesn’t focus only on time-series forecasting techniques: it englobes processes, people and tools needed at every step.

On the other hand, a beginner level on Excel (basic functions like Vlookup, Sum, If …) is useful to rebuild the Excel files quickly (be reassured, I film my screen step by step).

It is also important to have a stable Internet connection and Microsoft Excel installed on your computer.

Most of our pedagogy use Excel as a learning tool. But we also provide demonstrations of Machine Learning / Python for forecasting.

Those are demonstrations and not a course about coding or data science, because you would need much more time to deep dive into those subjects.

The goal is to make you more aware of the possibilities given by those tools: we also provide you external ressources if you want to go further.

You get access to the method in a replay platform, allowing you to go at your rhythm. Some very motivated trainees will go through it in a few days, while others will take a few weeks with less time. I record my screen as I build dashboards in front of you. Then, all you need to do is repeat my actions with your data. Or you can use mine to practice.

Once you have registered, you will immediately be emailed access to a site reserved exclusively for students. There you will find downloadable videos and Excel files organized in modules that cover everything you need to know one by one. We’ll get right down to business with simple examples.

We all have different schedules. That’s why our program is based on your availability and your desire to get up to speed quickly. You can log in and progress through the course at any moment and see improvement in the way your forecast after putting in practice the first few lessons.

The duration varies according to your initial level and how much you can apply in your company.

The training is designed to last 4 weeks (4 hours/week).

The busiest people (Directors, Managers and “Forecasting Firefighters” 🚒 …) will complete this method in less than 8 weeks (2 hours/week)

There is 16 hours of content and exercises to apply immediately, because I know your time is valuable and I will get right to the point.

Each module is broken down into short episodes of less than 10 minutes to allow you to progress quickly and at your own pace.

The resources (videos, tools, downloadable files) will be available immediately after your payment has been confirmed.

You will then have 1 year of guaranteed access to complete the course (most of our members complete it in less than 1 month). If you complete it before that time, your access will be extended for 5 years with full updates, this is to motivate you to complete the training and reward your commitment 💪

The resources are regularly updated with feedback from our participants as well as the evolution of tools and trends in Demand/Sales Forecasting.

The certificate, Excel and Power Point downloads will be available for life.

After your order, you have 60 days to review the course, apply my advice and decide if it meets your expectations.

If you haven’t progressed, just send an email for a 100% refund.

The only condition to be eligible for reimbursement is to try the techniques that are revealed in this program.

If you would like to certify more than one person from your team and receive individual support and additional bonuses.

Please contact us via the TEAM formula to receive a personalized analysis suiting your needs.

Excel 365 is used in this program. The files are compatible with versions 2013, 2016, 2019 and office 365 in French and English. 
The dashboards will however display slightly differently on excel versions prior to 2013 and MAC version (I will give several alternative solutions if you have a MAC).
