TopTarif relaunch press release
4 min read
With an agile and user-centred approach, interactive tools, as digital lead agency, is developing a new comparison portal for TopTarif Internet GmbH. The new portal puts consumers and their needs even more at the centre – for a provider comparison online that's actually enjoyable.

Berlin, 16 January 2018 – TopTarif.de is the free comparison portal for all contracts relating to electricity, gas, insurance and telecommunications. With its new website, TopTarif sets itself apart fundamentally from other comparison portals: the new type of tariff search targets a young, digital audience in particular. Rather than a plain list of tariffs, TopTarif now aligns closely with individual user preferences to give directly suitable recommendations. To achieve this goal, TopTarif commissioned interactive tools GmbH. The digital agency carried out the redesign of the www.toptarif.de portal – from consulting and strategy through UX research and usability testing to concept and design. Agile methods are a fixed part of the project, turning agency and client into one team.
Whether electricity, gas or insurance – instead of long tariff lists, TopTarif quickly and clearly identifies three suitable offers from several thousand tariffs based on the user's requirements. Starting right from the homepage, the user reaches their goal in just a few clicks and gets all the information at a glance. They can choose between the cheapest offer, the tariff with the best customer ratings, or the tariff with the best price-performance ratio. The product categories are gradually going live. Electricity and gas launched first in January. The further product areas of telecommunications, insurance and finance will follow.
Agile approach achieves maximum user-friendliness
"In the project we interlinked Scrum, Design Thinking and User Centered Design, and developed the entire project together with users," says Marcus Völkel, Management / Creative Direction at interactive tools. "The TopTarif team, together with us, focuses on the needs and expectations of consumers. With the relaunch, a completely redesigned comparison portal will position itself in the market, placing its users and their needs even more firmly at the centre." Joy of Use is therefore also at the heart of the user experience - as the perfect combination of function, content and design.
Design thinking and user-oriented solutions
"The innovative and individual tariff comparison meets very well the needs and expectations of a young and online-savvy target group," says Dr. Arnd Schröder, managing director at TopTarif. "In a design thinking workshop, the team from interactive tools developed an interactive prototype together with us in advance. It was tested and improved in several usability tests in the agency's own lab with test subjects – until an optimal result was achieved from the user's perspective. A result we're very pleased with. Because the target group understands it immediately and it's enjoyable to use."
Agile methods turn agency and client into one team
Agile methods are an essential part of this project. That's why interactive tools integrates customer as product owner into work process, so they take part in internal meetings, usability tests, sprint plannings and reviews. This gives them an overview of development status, lets them prioritise tasks, accept interim results and provide new input – which agency team implements directly in sprint-based work phases. This way, TopTarif always stays very close to production process and interactive tools can adjust project requirements virtually live. This creates solutions that fully match customer's objectives.
