Legacy Tech Is Costing You More Than Money - It's Stealing Momentum

The contradiction every leader feels

Digital transformation is still priority number one, yet customer experience scores across Australia are sliding. Why? Because too much of the budget - and the brain-space of your top people - is tied up nursing platforms nobody loves.

The Six Frictions

Over the past year, we've mapped six recurring pain-points inside mid-market stacks. They're not isolated issues; together they form a growth anchor.

Friction Quick pulse check
1. Maintenance Tax If more than 70% of the IT budget is "keeping the lights on", you are funding status-quo, not progress (Gartner, 2025).
2. Agility Anchor Forrester calls the rising backlog a "tech-debt tsunami"; nearly 70% of firms say it now slows every new feature launch (Forrester, 2024).
3. Talent Repellent 58% of developers are ready to quit over "embarrassing" legacy stacks (Storyblok, 2025).
4. Silo Tax Only 14% of Australian brands have a unified customer view despite first-party data being a top priority (Arktic Fox, 2025).
5. Security Debt Exploits of known, unpatched vulnerabilities grew 34% YoY and now drive one-fifth of breaches (Verizon, 2025).
6. Experience Deficit 37% of Australian brands saw CX scores fall in 2025 while another 58% stagnated (Forrester, 2025).

Why productivity is the real casualty

Maintenance Tax doesn't just waste money; it blocks every new line item the CMO proposes. Agility Anchor means product teams ship weeks late, letting nimbler rivals set the pace. Talent Repellent drains priceless domain knowledge. Add the Silo Tax, and the data you already own sits idle while marketing buys lookalike audiences. Meanwhile, Security Debt keeps the board awake and Experience Deficit leaks customers in plain sight.

A smarter modernisation play

Big-bang re-platform projects are out of favour for good reason. Instead:

  1. Diagnose first - quantify each friction in hours lost and dollars trapped.
  2. Redeploy capital - shift 10% of "run" spend into "grow" pilots that prove quick ROI.
  3. Go composable, not colossal - plug in best-of-breed capabilities where the drag is worst, rather than ripping out everything at once.
  4. Measure talent impact - show how freeing engineers from bug-fix duty unlocks roadmap velocity.
