Le Crime du paradis - Nouveau roman 2026

Guillaume Musso

Description

You're sitting on a goldmine of data. You're just not sure what to do with it.

Every day, your business generates numbers. Sales figures, customer transactions, operational costs, inventory levels. You know these numbers hold answers to your biggest questions. Which products are actually profitable. Why revenue dropped last quarter. Which customers are about to leave. How much inventory to order next month.

But between running the business and putting out fires, who has time to become a data scientist?

Here's the truth. You don't need to.

The most powerful analytics tool you need is already on your computer. You probably use it every day. And with the right approach, Excel can answer the questions that keep you up at night, without a statistics degree, expensive software, or a dedicated analytics team.

What Makes This Book Different

This is not another Excel manual listing every function from A to Z. It is not a theoretical statistics textbook that forgets you have a business to run.

This is a practical playbook written for managers, business owners, and decision makers who need answers fast, not impressive looking dashboards that sit unused.

You will learn how to:

Make Better Decisions

Identify which opportunities are worth pursuing and which will waste your resources Spot problems before they become crises Forecast future performance with realistic confidence Test assumptions before making expensive bets

Increase Profitability

Pinpoint your most and least profitable customers, products, and channels Optimize pricing using data rather than guesswork Reduce inventory costs while improving availability Uncover operational inefficiencies that quietly drain profit

Gain Competitive Advantage

Understand customer behavior patterns competitors overlook Predict which customers are at risk of leaving Benchmark performance against industry standards Move faster than competitors relying on intuition alone

What's Inside

Part I builds the foundation. You learn how to think about data like an analyst, prepare messy information, and focus only on Excel features that matter for business decisions.

Part II covers core analytics for finance, customers, sales, and operations. Each chapter solves a real business problem with practical steps you can apply immediately.

Part III introduces forecasting, scenario planning, and statistical thinking, explained in plain language using real business situations, not academic theory.

Part IV shows how to implement analytics inside your organization, avoid common mistakes, and build a data driven decision process that lasts.

The Practical Framework

Your Next Step

Data driven companies are not smarter than you. They simply ask better questions and use their numbers to answer them.

The data is already on your computer. The spreadsheets are already open. What you need is a system for turning numbers into decisions you can trust.

This book is that system.

If you want to grow revenue, cut costs, retain customers, or stop second guessing your decisions, the answers are already in your data.

You just need to know where to look.

Stop guessing. Start knowing.
