They emerge when projects are launched with unclear goals, conflicting expectations, and poorly defined requirements. The consequences usually only become visible months later\u2014but then with full force.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Most Expensive Mistakes Happen in the First Few Weeks<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At the start of many projects, there is immense time pressure.<br>The budget is finally approved, the project can begin, and the business department\u2014which has been waiting for a solution for months\u2014naturally pushes for rapid implementation. This creates a strong temptation to shorten the analysis phase, especially since teams have already discussed the problems and desired features for a long time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is where the first major mistake often occurs:<br>A misunderstanding in a requirements workshop may cost just a few minutes. The same misunderstanding after go-live can cost hundreds of thousands of euros.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As software engineering pioneers Barry Boehm and Victor Basili demonstrated in the late 1970s, errors detected in later project phases are exponentially more expensive to fix than those caught during requirements analysis. In many cases, correction costs increase ten- to a hundredfold. They referred to this phenomenon as the <strong>&#8220;Cost Escalation Factor&#8221;<\/strong>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Saving time on analysis rarely saves money\u2014it merely shifts costs to later phases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Numbers Are Alarming<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Poor requirements are not just a theoretical problem\u2014they have real-world consequences. Numerous studies highlight this:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The Project Management Institute (PMI) identifies inadequate requirements management as a key reason why projects fail to meet their goals. <\/li>\n\n\n\n<li>Research by the International Institute of Business Analysis (IIBA) and IAG Consulting found that poor requirements in large projects can lead to cost overruns in the millions. <\/li>\n\n\n\n<li>A study by Bent Flyvbjerg and Alexander Budzier (University of Oxford), based on 1,471 IT projects, revealed that projects exceed their budgets by an average of 27%. Even more critically, one in six projects became a &#8220;black swan,&#8221; overshooting planned costs by 200% on average while also facing severe delays. The root causes were rarely technological but instead stemmed from unclear objectives, unrealistic assumptions, and inadequate requirements definition.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Costliest Misconception: Confusing Features with Value<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A common mistake is that organizations describe what features a system should have in great detail but fail to define what value it should deliver.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The result? Specifications that look impressive on paper but miss the actual business need. Users only realize during operation that the system doesn\u2019t support their daily work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, the right questions should be asked:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What problem is being solved?<\/li>\n\n\n\n<li>Which key performance indicators (KPIs) should improve?<\/li>\n\n\n\n<li>How will success be measured?<\/li>\n\n\n\n<li>What value justifies the investment?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Without answering these, the outcome is often a system that meets all requirements yet is still perceived as a failure\u2014not because the software is bad, but because the expected value was never clearly defined.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Poor Requirements Trigger a Domino Effect<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">High costs from poor requirements are not just due to expensive late-stage changes. The real damage comes from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Procuring the wrong solution<\/li>\n\n\n\n<li>Project delays<\/li>\n\n\n\n<li>Claim and change management<\/li>\n\n\n\n<li>Budget overruns<\/li>\n\n\n\n<li>Increased testing efforts<\/li>\n\n\n\n<li>Low user adoption and productivity losses<\/li>\n\n\n\n<li>Missed business goals<\/li>\n\n\n\n<li>Additional operational and integration costs<\/li>\n\n\n\n<li>Loss of trust in IT projects<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These costs are difficult to quantify but often far exceed development expenses\u2014and their impact can linger for years after go-live.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Requirements Management Is a Leadership Responsibility<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Requirements engineering is often seen as an operational task. In reality, it is risk management in the context of investment decisions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Good requirements provide transparency on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Goals<\/li>\n\n\n\n<li>Value<\/li>\n\n\n\n<li>Scope<\/li>\n\n\n\n<li>Risks<\/li>\n\n\n\n<li>Priorities<\/li>\n\n\n\n<li>Quality<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">They form the foundation for sound decision-making. The larger and more complex a project, the more critical this transparency becomes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most IT projects don\u2019t fail due to a lack of skills or technology. They fail because different stakeholders have different understandings of what should be achieved\u2014or because the value the system is supposed to deliver was never properly defined.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why requirements are far more than just documentation. They are the basis for Investment decisions, Tender processes, Architecture, Development, Testing and Operations. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those who skip professional requirements management aren\u2019t saving effort\u2014they\u2019re taking a gamble. A gamble that all parties share the same understanding of the project and its goals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Experience shows: This bet is lost surprisingly often.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The costs of poor requirements rarely hit all at once. Instead, they accumulate through poor decisions, rework, delays, and missed value\u2014often exceeding the original investment in professional requirements analysis many times over.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sources &amp; Further Reading<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Project Management Institute (PMI): <em>Pulse of the Profession<\/em><br>https:\/\/www.pmi.org\/learning\/thought-leadership\/pulse<\/li>\n\n\n\n<li>Flyvbjerg, B.; Budzier, A.
