The reasoning was as simple as it was convincing. They opted for software that worked\u2014at least in theory.<\/p>\n\n\n\n<ul class=\"wp-block-list bamac-versprechen\">\n<li>Bringing best practices from the market into your own organization,<\/li>\n\n\n\n<li>predictable costs,<\/li>\n\n\n\n<li>Predictable project durations<\/li>\n\n\n\n<li>and a reduction in implementation risk by shifting the risks associated with development from the in-house development team to the provider<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 those were the promises that won over the decision-makers.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group bamac-kapitel\">\n<h2 id=\"k2\" class=\"wp-block-heading\">Dwindling Expertise: When In-House Development Reaches Its Limits in Terms of Personnel<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Added to this was a structural problem that had long been underestimated: As the baby boomer generation retired, not only was experience lost, but often also a deeply ingrained understanding of the logic and inner workings of the system landscape. In-house development thus became a challenge not only economically but also, increasingly, in terms of personnel.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group bamac-kapitel\">\n<h2 id=\"k3\" class=\"wp-block-heading\">The Flight to the Status Quo: Safety Became the Decisive Factor<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This gave rise to a paradigm that persisted for years: once-proud, monolithic core systems\u2014once the backbone of the organization\u2014had to be replaced by standard solutions\u2014not necessarily because they were superior, but because they were considered more manageable. For many organizations, this was less a technological relief than a psychological one.<\/p>\n\n\n\n<p class=\"bamac-solo wp-block-paragraph\">But this paradigm is increasingly being called into question.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group bamac-kapitel\">\n<h2 id=\"k4\" class=\"wp-block-heading\">The Turning Point: Why the Equation Doesn&#8217;t Necessarily Add Up<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The expectations once placed on off-the-shelf software are increasingly rarely met in practice. The reality is more complex: off-the-shelf software is rarely truly standard. Processes that have evolved over time, customized pricing structures, and unique business logic cannot be easily mapped \u201coff the shelf.\u201d<\/p>\n\n\n\n<p class=\"bamac-solo wp-block-paragraph\">This results in extensive customization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What was planned as a predictable investment often turns into a costly transformation program. Market-differentiating features are lost, implementation projects drag on for years, budgets are exceeded\u2014and the hoped-for cost advantages are increasingly diminished or disappear entirely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, off-the-shelf solutions are often technologically closer to the legacy systems they are meant to replace than one might expect. Replacing an old system with one that is only marginally more modern rarely creates a real competitive advantage.<\/p>\n<\/div>\n\n\n\n<p class=\"bamac-aera bamac-aera-neu wp-block-paragraph\">The New Paradigm<\/p>\n\n\n\n<div class=\"wp-block-group bamac-kapitel bamac-kapitel-neu\">\n<h2 id=\"k5\" class=\"wp-block-heading\">The key insight: Legacy systems are a strategic asset<\/h2>\n\n\n\n<p class=\"bamac-kernaussage wp-block-paragraph\">The key insight, therefore, is this: Legacy systems, which were long considered a burden, are increasingly proving to be strategic assets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Over the years, these systems have come to reflect processes, technical distinctions, and company-specific logic. On the one hand, this cannot be easily standardized. On the other hand, these systems document the knowledge about an insurer\u2019s business model that has been gradually lost over the years due to demographic shifts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This realization fundamentally changes the nature of the question. It is no longer just a matter of how quickly and with minimal risk a legacy system can be replaced.<\/p>\n\n\n\n<p class=\"bamac-solo wp-block-paragraph\">What matters most is what must not be lost under any circumstances.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group bamac-kapitel bamac-kapitel-neu\">\n<h2 id=\"k6\" class=\"wp-block-heading\">The Game-Changer: AI Is Changing the Rules of the Game<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It is precisely at this stage that a new player enters the scene and changes the rules of the game: artificial intelligence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What at first seems like just another technological promise is increasingly turning out to be a real game-changer. That\u2019s because AI addresses precisely the weaknesses that have so far limited both in-house development and off-the-shelf software.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the field of development, AI is taking productivity to a whole new level. Tasks that used to take months can now be completed in a fraction of the time\u2014not just incrementally, but in significantly larger leaps.<\/p>\n\n\n\n<div class=\"wp-block-group bamac-kennzahl\">\n<p class=\"bamac-kennzahl-wert wp-block-paragraph\">Factor 1,000<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Initial measurements show performance increases by a factor of several times, and in some specific applications, even by a factor of 1,000.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">This fundamentally changes the cost-benefit analysis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the same time, AI opens up new possibilities for working with existing legacy systems. What was once considered a difficult-to-access \u201cblack box\u201d can now be systematically analyzed, structured, and made transparent in terms of its business logic. Knowledge that was thought to be lost can thus be reactivated. This not only makes migration more manageable but also leads to a fundamental reassessment of its quality.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group bamac-kapitel bamac-kapitel-neu\">\n<h2 id=\"k7\" class=\"wp-block-heading\">The Key to Success: Process Expertise Becomes a Strategic Resource<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The changes affect not only IT, but the entire organization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The traditional developer is taking a back seat. What will be crucial is the ability to understand business processes and integrate them with technological capabilities. The entire development cycle\u2014from requirements to implementation\u2014is being gradually automated, extending all the way to the development of new systems. With agent-based AI approaches, applications are created through the orchestrated interaction of specialized AI agents.<\/p>\n\n\n\n<p class=\"bamac-kernaussage wp-block-paragraph\">This makes process expertise a key competitive advantage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Companies that can clearly structure and describe their value creation are able to translate it quickly and efficiently into effective systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All in all, the economic impact is substantial: development and operating costs decrease significantly, while speed and adaptability increase.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This marks the return of an option to the strategic agenda that many had already written off: in-house development\u2014albeit under entirely new circumstances.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group bamac-kapitel bamac-kapitel-neu\">\n<h2 id=\"k8\" class=\"wp-block-heading\">The Implication for Decision-Makers: IT Is Once Again Becoming a Differentiator<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For company management, this has a clear implication: The role of IT is undergoing a fundamental change.<\/p>\n\n\n\n<p class=\"bamac-solo wp-block-paragraph\">The question is no longer whether legacy systems should be replaced, but how this transformation can be leveraged strategically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the first time in decades, there is an opportunity not only to make IT more efficient, but also to use it once again as a key differentiator.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group bamac-cta\">\n<p class=\"bamac-cta-label wp-block-paragraph\">Legacy Transformation with BAMAC<\/p>\n\n\n\n<h3 id=\"h-wie-strategisch-nutzen-sie-ihre-transformation\" class=\"wp-block-heading\">How are you strategically leveraging your transformation?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">We support banks and insurance companies every step of the way\u2014from analyzing their existing system landscapes to implementation\u2014and help identify which knowledge must be preserved.
