Why modernisation projects fail (and how AI reduces risk)
Modernising legacy systems is one of the most critical and complex challenges facing today’s IT leaders. Whether you're in government, finance, or education, the pressure to replace ageing infrastructure with agile, user-friendly, cloud-based platforms is real.
But despite best intentions, many modernisation projects still fail. Timelines slip. Budgets blow out. Users resist change. And the promised business value never materialises.
Navigating Digital Transformation: Overcoming Common Pitfalls
So why does this happen and how can artificial intelligence (AI) help turn the tide?
The 4 common reasons modernisation fails
1. Incomplete understanding of the legacy system
Often, organisations no longer have access to the original developers or documentation. Critical business logic is buried deep in ageing codebases making them difficult to decode and dangerous to touch.
2. Underestimating complexity
Legacy systems tend to be highly customised, integrated with dozens of other tools and data pipelines. Rebuilding or replacing them is rarely straightforward.
3. Lack of iteration
Many projects take a “big bang” approach switching off the old system and turning on the new one overnight. This rarely works seamlessly. Without an iterative delivery model, feedback loops and risk management, your users and your business will suffer.
4. User resistance and low adoption
Even the best-built system will fail if users aren’t brought along for the journey. Without early involvement and thoughtful design, modernisation can feel like disruption, not progress.
How AI can reduce modernisation risk
AI can’t solve everything but when used strategically, it significantly de-risks legacy system modernisation.
✅ Faster code analysis
GenAI tools can scan legacy codebases and surface structure, business rules, and integration logic. This shortens discovery time, bridges knowledge gaps, and helps plan realistic timelines. [Link to case study]
✅ Accelerated UI development
AI-generated UI components allow teams to prototype and iterate faster. At Kiandra, we’ve used this approach to cut design time by up to 70%, enabling earlier feedback from real users.
✅ Smarter integration layers
AI-assisted code generation helps create the glue between old and new enabling you to wrap, replace, or gradually retire legacy systems with less risk.
✅ Augmented developers, not replaced ones
AI code assistants enhance your team's output, helping experienced engineers move faster and focus on solving the hard problems - not boilerplate.
The bottom line
Modernisation projects fail when complexity is underestimated and discovery is rushed. AI offers a new way to approach legacy systems with more confidence, more clarity, and less risk.
At Kiandra, we combine extensive human experience with AI-powered tools to deliver modern software that works - faster.
