Modernize wisely: Application modernization in the public sector

Read the white paper
People moving through a busy urban square, representing connected city life and digital public services.

Many public IT solutions have been built up over decades. They support critical functions and complex legislation, but they can also be difficult to change because technical dependencies, integrations, and business rules are tightly interwoven.

For many organizations, the challenge is therefore not only to modernize, but to determine which applications should come first in the queue and how to do so in a way that is realistic, manageable, and decision-wise sustainable. Experience shows that the best modernization initiatives rarely start by tearing everything down and starting from scratch. Instead, they begin by creating transparency, prioritizing correctly, and delivering improvements step by step.

This guide provides you with a practical model to:

  • Identify relevant modernization candidates

  • Build a business case that secures buy-in and a shared understanding

  • Consider important perspectives such as security, ownership, robustness, and AI

  • Choose the right modernization approach
