Tape à l'Œil: train the entire headquarters staff on generative AI using the internal tool, then the regional directors
At the end of 2024, Tape à l'Œil made an internal and secure generative AI assistant available to its teams. After consulting with four organizations, the training manager entrusted NextStart with its implementation by headquarters staff. Ten half-day Prompt Sprints, held in person in Wasquehal, began with a test session, followed by a 3.5-hour session tailored for the sixteen regional directors: in four months, 136 participants went from discovery to practical application on their own tool.
The starting point: an internal assistant to be adopted by the entire headquarters
Tape à l'Œil, a children's fashion retailer headquartered in Wasquehal, near Lille, will launch an internal generative AI assistant for its employees at the end of 2024. This assistant will be deployed and secured by the IT department. The challenge now is to integrate it into the daily operations of all head office functions, from purchasing to IT.
In November 2024, the training manager consulted several organizations. On December 9, NextStart proposed training all headquarters staff in small groups, starting with a half-day trial to validate the content before deployment. At the end of December, NextStart was selected as one of the four organizations consulted.
The specifications set three requirements: to work directly on the company's internal tool rather than on consumer tools, to compose heterogeneous groups (approximately one-third beginners, one-third occasional users and one-third regular users), and to leave with use cases applicable the very next day.
The objective: that every employee at headquarters masters the best uses of generative AI, knows where it excels and where it falls short, and has practiced on their own tasks within the security framework set by the company.
The plan: a test session, Prompt Sprints at headquarters, then regional directors
All sessions take place in person, led by Flavien Besset, with participants at their workstations and on the company's internal assistant.
Test session at headquarters (March 18, 2025)
The first half-day was spent in real-world conditions, with the training manager and the IT department present. The very next day, the training materials were enhanced with feedback from the group, then adjusted after a debriefing and a list of changes drawn up by the training manager. The deployed version is the third.
Prompt Sprint “Mastering the best uses of generative AI”
Ten half-days at the Wasquehal headquarters, including a test session, in small groups, until spring 2025. The program includes: understanding what generative AI does, best practices in prompting, and then a Prompt Party where everyone tests the assistant's "superpowers" on provided documents: writing, summarizing, analyzing, reformulating, self-challenging.
Content adjusted after each day
At the end of each session, participants jot down on sticky notes what they have learned and what needs improvement. This feedback is then sent to the training manager that same evening, and the training materials evolve from one session to the next: the introduction is shortened, the practical prompts are revised, and the use cases are better targeted to the specific roles of the participants.
Regional Directors' Prompt Sprint (June 19, 2025)
"Best practices for regional directors": 3.5 hours for the 16 regional directors, gathered in Belgium for a dedicated day. A preliminary questionnaire identified their tasks and pain points, ten use case ideas were derived, and two days of instructional design were used to develop exercises based on their data, including the analysis of a sales file, under a confidentiality agreement.
The measured results
Ten half-days of practical training on the internal assistant, from discovery to advanced uses, with groups that mix beginners and regular users.
"Very concrete and practical for quick implementation in our daily lives", "hyper concrete and interactive", "easy to practice with the documents provided": practice on real tasks comes up in most of the feedback.
Following the headquarters session, the company entrusted NextStart with a dedicated session for its 16 regional directors. The feedback was very positive overall, with one phrase recurring: "suited to our job".
Three versions of the support material in one month, then adjustments every day: the final content reflects Tape à l'Œil's business, documents and security rules.

What they say
"It seems clear that you are experts in the field, and your offer is interesting and highly accurate."

Participant, Prompt Sprint from headquarters, 2025

What we take away from this
The half-day test, followed by a debriefing with the training manager and the IT department, allowed us to fine-tune the content, pace, and tool before rolling it out to the entire headquarters. A technical rehearsal on the internal assistant the day before each session completes the process.
The general use cases resonate with most of the headquarters staff, but less so with technical profiles. For regional directors, the preliminary questionnaire allowed them to develop exercises based on their own tasks, and it is this adaptation that they cite first.
