We consult you and your project

We have the answers to your questions...

Requirements Engineering

What is the value proposition of each feature? How to efficiently prioritize requirements? Which tools should I take to gather the requirements?

HW & SW Engineering

Which architecture fits best to my requirements? How do I shift my processes/data to this new technology? How do I efficiently use UML or other modeling languages?

Process Modeling

Who is involved in my product-lifecycle? Which tool environment should I use to model the processes? How can I detect bottlenecks in my processes?

Lean & Agile Development

Always wanted to introduce Scrum to your development process? Do you want to minimize your engineering costs, which have increased due to less value generation and more resource management?

Data Harmonization

How can I harmonize my different data bases? What are the interfaces between the different databases/tools we are using? Which tools must be replaced by new technologies?

Business Development

Tired of updating the same business plan again and again? You are working only with Excel and Word and repeatedly the documents do not fit together?


You know that there are some governmental funding initiatives, but you have no idea which one fits to your business idea? No time to write tons of proposal documents?


You have a business idea, but no team around you that implements it? You have timelines, budget parameters and talent criteria, but no clue where to hire your technical human resources?


Already implemented something? You don’t know where to get people who are testing your user interfaces, features or processes in order to verify the value propositions?

Our Testimonials

RSIT consulted our association for a test-pilot project that introduces new ways in the Austrian e-Tourism landscape. He helped us to address the risks, processes and resources that are necessary for a successful implementation.

Markus Gratzer

- General Secretary of Austrian Hotel Association ÖHV
We worked with Dr. Rainer Schuster throughout the entire software architecture selection process. The knowledge and experience was extremely helpful as this area of building new innovative software was definitely new for us.

Carlos Gomez

- CEO of WingPaper
We successfully use a software developed by RSIT that helps us to analyze different data sets within our company. The main goal was to automatically detect duplicates, which helped us to improve our processes during customer support.

Dieter Kindl

- CEO of Rakuten Austria GmbH
RSIT supported us during the planning phase of the implementation of new digital media channels for pdf-magazines. The new concepts introduced in terms of business development, funding and requirements engineering were crucial, in order to finally start with such a big SW project.

- Editor in Chief of VANGARDIST Magazine

We transform your ideas into mobile Apps

No matter if you would like to have a native App, that is available in the app store or if you would like to have a responsive web application, that looks same on any device. After we have clarified your business objectives and user needs, we start to draw wireframes to get a basic UX feeling. We design a prototype for your Andoid or iPhone App to conduct first usability tests. Once the UI is finalized we work on with our graphic design partners to create a unique design for your application. After having set up the design, we will implement the application according to the requirements. Of course, we support you in all the different phases of registering an App at the different vendors’ app markets. In other words, we support the whole lifecycle of developing an App.
