The numbers have not moved in the way they should. Despite sustained investment in project management methodology, tooling, and training over the past decade, IT project failure rates in UK organisations remain at levels that most boards would consider unacceptable if they were presented with them as a business risk rather than an operational norm. According to the Standish Group’s CHAOS Report, analysis of data from the 2020 to 2024 cycle shows that over 50% of IT projects are classed as “challenged” – late, over budget, or delivering less than was intended — and approximately one in five fails outright. A 2024 McKinsey analysis found that while 59% of IT projects are completed within budget and 47% on time, just one in 200 meets all three primary measures of success: on time, on budget, and delivering the intended benefits.
These are not the statistics of an industry in crisis. They are the statistics of an industry that has normalised underperformance. What makes them particularly worth examining in 2026 is not their scale but their persistence. Failure rates have remained broadly consistent across years of methodological evolution – from waterfall to agile, from agile to hybrid – suggesting that the underlying problem is not one of process or tooling. It is structural. The organisations that consistently deliver IT projects on time, within budget, and to the agreed scope are not doing so because they have found the right methodology. They are doing so because they have made different decisions about governance, resourcing, and how early in the project lifecycle risk is taken seriously.
Understanding what those decisions are, and why most organisations are still not making them, is the more useful question.
The Research on Why Projects Fail: Moving Past the Surface
Post-project reviews and industry surveys consistently surface a familiar list of failure causes: poor stakeholder engagement, unclear requirements, scope creep, inadequate executive sponsorship. These are real, and they are not wrong. But they describe symptoms rather than the conditions that produce them. The research base, when examined at the structural level, points to a more specific set of determinants.
PMI’s 2025 Pulse of the Profession report identifies business acumen – the ability to connect project activity to organisational value – as the critical differentiating capability, noting that only 18% of project professionals demonstrate high proficiency in this area. The implication is not simply that project managers need better skills. It is that organisations are routinely running projects whose strategic alignment is poorly defined at the point of inception, and that governance structures are not catching this early enough to correct it. A separate longitudinal analysis published in the PM World Journal in January 2026 drew on CHAOS Report data from 2020 to 2024 and concluded that success rates have stagnated despite widespread agile adoption, arguing that “the root causes of failure have shifted from process execution to strategic alignment and data governance.”
On the resourcing side, the picture is equally clear and arguably more acute. The UK IT skills shortage, which ManpowerGroup identified as reaching an 18-year high of 80% in 2024, has begun to ease marginally – falling to 76% of employers reporting difficulty filling roles in 2025 -but IT and data skills remain the hardest to source of any discipline, a position unchanged for five consecutive years. Critically, this is not a general hiring problem that IT happens to share. IT project delivery roles, which require a specific combination of technical literacy, governance knowledge, and stakeholder management capability, sit in the most constrained part of an already constrained market. Over half of UK businesses surveyed in 2024 admitted to settling for less qualified professionals due to a lack of suitable candidates.
The consequence is a delivery environment in which organisations are running more projects than their governance structures are equipped to oversee, with teams that are under-resourced in capability if not always in headcount. In this context, project failure is not bad luck. It is a predictable output of identifiable structural conditions.
What the Evidence Shows About High-Performing Delivery Organisations
The following section examines the specific governance and resourcing factors that current research most consistently associates with stronger delivery outcomes — and considers what they mean for IT leaders managing project portfolios in 2026.
