TUI, Europe’s largest tourism company, faced the challenge of optimizing mobile bookings for package holidays. Despite a steady increase in mobile traffic, the conversion rate on mobile devices remained behind that of desktop.


To address this, the Co-Creation Studio "Team 300" was established in 2019. The goal was to fundamentally redesign the mobile booking experience and increase the conversion rate by 300%.

  • Card in bright blue colour with stacked input fields. The fields contain the texts "Where are you going?", "From where?", "2 adults, 1 child", a date and duration (in the example: 14 days), sample search criteria "Water slide, wellness, pool". Below is a red button with the label "Find offers".
  • ""
  • Simplified representation of the mobile view for destination search. With the text "1. Where are you going?". Below it, an input field with the text "Discover more destinations...". Right next to it is the symbol of a magnifying glass. Below are nine pill-shaped clickable filters with destinations such as "Mallorca", "Turkey", "Egypt".
  • Advertising graphic titled "Top Offers for Families" featuring three hotel offers from TUI arranged side by side. In the foreground highlighted is the hotel "Blue Star Stefan Village" in Crete with a pool view, rated 9/10, 87% recommendation, and the original price of €3,567 crossed out alongside the new price of €3,189. To the left and right are two additional offers: "Alcheaeles" and "TUI Blue Grupotel Mar".
  • Screenshot of the TUI travel booking app with a countdown timer showing how long the reservation is still valid (2 days, 22 hours, 42 minutes, 11 seconds). Below are form fields for travellers, payment method, insurance, and extras, as well as a total price of €2,496.00 including travel insurance. At the bottom, there is a red button that says "Book now for a fee".

Co-Creation Studio "Team 300"

Through close, interdisciplinary collaboration, we succeeded in breaking down silos and accelerating innovation. The established end-to-end team was empowered to make decisions independently and drive solutions forward. The neutral environment in a shared Co-Creation Studio provided the space for focused work, quick alignment, and practical results—far from the usual corporate structures.

In the centre are the TUI and DAYONE logos as well as the text "End-to-End Team".

Data-Driven Design for Measurably Better Results

Design decisions were made based on data and user insights. Through continuous testing and validation, a booking process was created that performs measurably better. Only features that provided real value for users and the business were developed.


For example, an A/B test showed that offering a comparison function in the wish list increased the conversion rate by 15%.

Circle Organization: Flexibility within the Core Organization

The self-organized team structure ensured clear responsibilities, high accountability, and fast implementation paths. At the same time, integration with existing TUI processes was ensured, making the results sustainable and scalable.

Within TEAM 300, there are additional circles with the terms "Vision Strategy", "Delivery", "Ideation", "Dev.", "Iteration" visible. Outside of TEAM 300, but within TUI, there are more circles labelled "Management", "Change Management", "Scaling", "Design System", and "6M Micro Frontends". Red dashed lines connect the outer circles "TUI Management", "TUI Change Management", "TUI Scaling", to the inner team.
