Eureka Case 25 min Data & Technology

Five Weeks to Aurore

You are Camille Aubert, creative director of Lumen & Co., the in-house studio of a Paris cosmetics group. The chief marketing officer wants the relaunch of Aurore, an €88 million skincare line, shipped across six channels in five weeks on €1.8 million. Before you split the work between your people and your artificial-intelligence tools, you have to name the task where getting that split wrong would do the most damage.

The situation

Monday 4 May 2026. Florette Beauté turns over €620 million at a 13% operating margin, and Aurore, its flagship line, is losing ground to a direct-to-consumer brand that has taken six share points in eighteen months. The brief: six channels, five weeks (40% less than usual for a campaign this size) and a fixed production budget of €1.8 million. That morning the studio dashboard shows projected delivery at 8.0 weeks, distinctiveness at 70 against a baseline of 100, expected audience engagement at 45 out of 100, and not a euro committed yet.

Lumen has 62 people, about 140 campaigns a year and a three-person data-and-AI cell set up last year. Its tools come in two families: generative ones, which produce copy, images and variants, and non-generative ones, which analyse audiences and predict performance without creating anything a customer sees. You championed them. Last spring the launch that leaned on them most tested 18% below the brand's distinctiveness baseline: polished and forgettable, the board said. And last quarter a generated visual came close enough to a rival's hero image to need a legal review before print.

Aurore's work splits into very different pieces: the core concept and brand voice; the production of hundreds of variants and resizes for each channel; the localisation of copy and assets market by market; and the support work, from predicting which audiences will respond to tagging the asset library. Doing it all by hand would cost about €2.4 million and miss the date, so part of the work will go to the machines.

Your job in this case: decide which of these tasks is the one where a wrong balance between people and machines would do most damage to the relaunch. The plan for the five weeks will be built around that answer.

The decision

On which task would a wrong human-AI balance do the most damage?

  • A · The core concept and the brand's voice
  • B · Variant production for hundreds of placements
  • C · Localisation of copy and assets by market
