Short: Digitization has long since captured all areas of our society – including public administration.

Digitization has long since captured all areas of our society – including public administration.

From the digital application of a new identity card to the electronic tax declaration: Modern software solutions are the key to more efficient, citizen-friendly and transparent management processes.

But the ** software development for the public sector** is not an ordinary IT project. It is subject to unique framework conditions and presents developers with special challenges.

In this article we highlight the specific requirements and peculiarities to be observed in the development of software for authorities and state institutions.

The uniqueness of the public sector

Short: In contrast to the private sector, the public sector operates in a highly regulated environment.

In contrast to the private sector, the public sector operates in a highly regulated environment. Legal requirements, complex hierarchies and long-term decision-making processes shape everyday life.

Software must not only be functional, but must seamlessly integrate into existing administrative structures and address a broad, heterogeneous user group – from administrative staff to citizens of all age and technology levels.

This uniqueness leads to a catalogue of requirements that goes far beyond purely technical aspects.

Special requirements for software development

Short: Anyone who develops software for the public sector must meet a variety of specific requirements.

Anyone who develops software for the public sector must meet a variety of specific requirements. These can be divided into four central areas:

Security and privacy

Protection of sensitive civil and administrative data is a top priority. State IT systems are an attractive target for cyber attacks, which is why IT security requirements are extremely high.

Developers must strictly comply with the requirements of the General Data Protection Regulation (GDPR) and national laws such as the BSI Act. The principle “Security by Design” is not an option here, but a necessity.

This means that security aspects must be integrated from the start into the entire [development process](/services/software development), from architecture to implementation and regular security tests.

Accessibility and usability

Public services must be accessible to all citizens. Digital offers are no exception here.

According to the Barrier-free Information Technology Regulation (BITV 2.0), public websites and mobile applications must be designed so that they can be fully used by people with disabilities.

This includes aspects such as a clear structure, simple language, customizable font sizes and compatibility with screen readers. A high usability also ensures that the software can be used intuitively and efficiently by all users, making the app
