Test victory for the WISO tax programs, apps and web services!


Buhl Data Service GmbH is one of Germany’s leading software development firms. Since 1986 it has been developing and marketing software for tax returns, personal finance management and business solutions for smaller firms.
Working closely with the Buhl team, Ergosign redesigned the well-known tax application WISO Tax Savings Book. This software enables users to fill out their tax return themselves and to submit it online or to print it out on the official forms. It is easy to learn. The clear layout, intuitive user guidance and comprehensive help support the user throughout. In addition, the WISO Tax Savings Book gives valuable professional tax advice and individual tax saving tips. 
The two teams from Ergosign and Buhl worked closely together on the further development and strategic extension of the existing range of products. Thus mobile applications for iPads and android tablets (WISO Tax: app for iOS and android) as well as a web application (WISO Tax: web) were added to the product line with the desktop solutions for Windows (WISO Tax Savings Book) and for Mac (WISO Tax: Mac).

A fantastic result that could hardly have been better. Our combined exertions […] are thus rewarded! ”

Peter Schmitz, Buhl Tax Service GmbH

The products from Buhl were among the fourteen tax programs, apps and web services included in this year’s Computer Bild (7/2015 edition) tax software test. For the third time running, the WISO Tax Savings Book was the best buy in the category PC programs, winning the most exacting test in this sector. The jury praised the reliably correct results for all the test cases and, in particular, ease of data entry, convenient operation and the best advice for savings. In addition to these, the exemplary test for plausibility and the help with discrepancies were praised. 

The two WISO web services landed first and second in the category web services and apps including best in test for WISO Tax: web!

Computer Bild tested tablet apps for tax returns. Both of the new tablet apps, WISO Tax: app for iOS and for android - so far the only ones in this category, even attained better results than all the other online services of the competitors.

We are very pleased about the Buhl team’s great success and look forward to continuing our cooperation and to further developing the Buhl product range together.

UX Trends in Enterprise, Industry und Healthcare


We live in a time marked by the great speed of innovation and technological change. This places the designer of human-machine interfaces in a position of increasingly significant responsibility (to society). ”

Sebastian C. Scholz (UX Director, Head of Munich Office)

This responsibility means it is essential that we identify the main changes and trends in order to make the right decisions for a successful user experience design. Our Trend Report brings together our observations, and formulates them into challenges and opportunities within the sectors of enterprise, industry and healthcare.

For enterprise applications, the focus is on the increasing decoupling of data and functionality and the move from software producer to “curator of data”.

In the context of industrial applications, humans and machines perform as intelligent partners under the heading of Industry 4.0, which leads to increased efficiency.

In the healthcare sector, the focus is on the increasing use of sensors and the resulting collection of health data as well as on the newly defined self-determination of patients.

For each of these three areas, we discuss the current situation, predicted developments and resulting implications for the design of user experience.

We very much look forward to your feedback and to stimulating discussions.

Review of the Hanover Fair 2015



This year’s Hanover Fair took place from 13 to 17 April. About 6,500 firms from seventy countries presented their new products and services at the world’s leading industrial fair. More than 220,000 trade visitors came to catch up on the current trends in technology and innovation around the themes of Industry 4.0 and smart manufacturing.

The guiding theme of the fair was “Integrated Industry – Join the Network” with an emphasis on various subjects like industrial automation and IT. The major challenges for Industry 4.0, such as universally accepted standards for machine-to-machine communication, the question of data security and the search for a business model for the future, can only be tackled in the network. In this context, IT-supported automation solutions, digitally integrated manufacturing and the latest developments for 3-D models and visualisation were presented.

The implementations and exhibitions that we saw aroused my curiosity about future developments in industry. ”

Natalie Oster

Our senior UX designer and co-lead for industry solutions Natalie Oster was at the fair to forge new contacts and to take part in the Forum 4.0 panel discussion “SMART operation – User experience for successful products in the era of Industry 4.0”. All the speakers were agreed that user experience is an integral part of Industry 4.0 in order to convey the interaction of the individual stages of production to the users and to have an influence on it.
