Digitalization and AI. Today with the thesis: <\/strong><\/p>\n

Custom development is dead. Long live AI-based custom development<\/em> <\/strong><\/p>\n

Why the possible death of traditional software development is not a tragedy, but the beginning of a new era in which custom solutions and standard solutions ultimately converge.<\/p>\n

AI & Development<\/p>\n

Once upon a time, software development meant: months of requirements analysis, thick specification documents, teams of developers, multi-year projects, and ultimately a system that was already half obsolete upon delivery.
\nWelcome to the world of traditional custom development.<\/p>\n

Then came the era of “agile development.” Fast and in small increments. Unfortunately, often in chaos and with costs no one had anticipated. <\/p>\n

But what comes next? Now that AI is more than just “on everyone’s lips”? <\/p>\n

These times appear to be over. Not because custom development as a concept has failed, but because in its previous form it is simply no longer competitive. <\/p>\n

What is replacing it is something more fascinating: a new generation of custom software that emerges faster, cheaper, and more adaptively than ever before with AI support, while seamlessly integrating with proven standard solutions.<\/p>\n

“The code was never the goal. The goal was always the solution to a specific business problem.” <\/em><\/strong><\/p>\n

A statement that is more relevant today than ever<\/p>\n

The possible end of an era and why we should not mourn<\/strong><\/p>\n

Traditional custom development had its price. Not just financially. Although six- to seven-figure project budgets for medium-sized applications are not uncommon, but also in terms of time and organization. Average project durations of 18 to 36 months<\/strong> in a world that changes on an annual or even quarterly basis are simply anachronistic. <\/p>\n

When so-called agility arrived, there were smaller, functional “increments.”<\/em><\/strong> Nevertheless, it took time until the final result was available.<\/p>\n

The traditional model still had its purpose<\/strong>: Those who needed a highly specialized system that no standard product could provide had no alternative.<\/p>\n

ERP, WWS, or WMS systems (just as examples) never fit 100% to one’s own processes. Industry-specific workflows remained stuck in the generic. The gap between “what the system can do”<\/em><\/strong> and “what the company needs”<\/em><\/strong> was bridged through expensive customization projects, Excel jungles, or workarounds. <\/p>\n

Especially when one wanted to develop a competitive advantage from it.<\/p>\n

What AI can truly change in software development!<\/strong><\/p>\n

It would be naive to believe that AI “simply writes code.”<\/em><\/strong> What actually happens is more subtle and profound: AI assistants like GitHub Copilot, Claude, Cursor, or similar tools fundamentally change the productivity curve<\/strong> of developers.<\/p>\n

Studies show that experienced developers with AI support deliver productive code 30 to 55% faster<\/strong>. For less experienced developers or domain experts without traditional programming skills, an entirely new door opens: They can formulate logic with natural language prompts, specify requirements, and validate initial working prototypes\u2014capabilities that previously resided exclusively within development teams. <\/p>\n
