Legacy Drag: When Maintenance Eats the Innovation Budget
Nearly half of UK IT organisations are redirecting innovation funding into keeping legacy systems alive — most cannot say precisely which systems, at what cost, blocking what.

The Numbers Behind the Drag
The Challenge
Legacy Drag Has Become the Binding Constraint on the Board's Most Visible Ambition
UK IT estates are carrying the accumulated weight of decades — and the bill is now being paid out of the innovation budget. In a 2025 survey of 250 UK IT leaders across government, finance and manufacturing, around 45% reported that funding is being redirected from innovation towards maintaining legacy systems, and nearly half had faced compliance challenges in audits attributable to legacy IT. The pattern is not new, but its price has changed: McKinsey's survey of 50 CIOs found 10 to 20 percent of the technology budget dedicated to new products diverted to resolving tech-debt issues, with tech debt estimated at 20 to 40 percent of the entire technology estate's value.
What has changed is the opportunity cost. The estates that would benefit most from AI are precisely the ones least able to fund and integrate it — legacy drag has become the binding constraint on the board's most visible ambition. And without application-level transparency on cost, ownership, risk and business criticality, rationalisation remains anecdotal: the loudest system gets modernised, not the one blocking the most value.

The Bee360 Solution
Answers Before Diagrams
Estate transparency fails when it is attempted as a multi-year modelling programme — the organisation loses patience before the picture is complete. Bee360's Fast-Track EAM approach inverts the sequence: a decision-grade application portfolio in weeks, capturing cost, ownership, business criticality, risk and dependencies first, architectural depth where decisions demand it. Because the same platform carries portfolio, demand and financial data, “legacy” stops being an adjective and becomes a quantified position — which systems consume what, block what, and would release what if retired. The Manitowoc Company runs its IT organisation on Bee360 today, alongside European engineering groups including Herrenknecht, Flender and Phoenix Contact.
Analyst recognition: Bee360 is a SPARK Matrix Leader for Enterprise Architecture Management (Quadrant Knowledge Solutions, 2021–2024), appears in Gartner's Magic Quadrant for Enterprise Architecture Tools (2025) and Market Guide for Application Portfolio Management (2026), and was evaluated in the Forrester Wave™ for EAM Suites (Q4 2024).
