NTT DATA runs a global platform engineering team supporting hundreds of enterprise clients across 50+ countries. IntelliTune auto-resolved 80% of on-call incidents in the first 30 days — without waking a single engineer.
NTT DATA's platform engineering team supports enterprise clients across financial services, healthcare, government, and manufacturing. Operating globally across 50+ countries means their on-call rotation spans every time zone — and the volume of alerts was relentless.
Before Applicare, the team averaged 21 on-call pages per week. Their best engineers were spending Sunday nights and early mornings triaging alerts, the majority of which turned out to be transient issues that resolved themselves or required the same remediation they'd performed dozens of times before.
The real cost of 21 weekly pages wasn't the time spent — it was the talent drain. NTT DATA's most experienced platform engineers were spending 30-40% of their time on reactive incident response instead of engineering improvements for clients.
Applicare deployed IntelliTune across NTT DATA's multi-cloud client environments, starting with a conservative policy gate configuration. For the first two weeks, every proposed remediation was surfaced to the engineering team for approval — building confidence in the patterns before enabling automatic execution.
By week three, the team had approved automatic execution for 47 of the 200+ available patterns — the ones they had personally reviewed and confirmed were safe in their environments. The result was immediate: the patterns that had been generating 80% of their on-call pages were now being handled automatically, in 400ms, before PagerDuty could even fire.
After 30 days, the team ran an analysis of which IntelliTune patterns had been responsible for the page reduction. The top 10 patterns accounted for 17 of the 17 eliminated pages:
With 17 fewer weekly pages, the platform engineering team redirected their expertise toward proactive improvements. In the 90 days following deployment, they completed three major infrastructure modernisation projects that had been perpetually delayed by reactive incident response work.
Before Applicare, our on-call averaged 21 pages a week. IntelliTune auto-resolved 17 without waking anyone up. My team stopped dreading Monday. Now we spend our energy building things instead of fixing the same five problems every weekend.
Following their internal success, NTT DATA began offering Applicare-powered managed observability as a client service. Within 6 months, they had deployed the same IntelliTune automation model for 14 enterprise clients, with an average on-call page reduction of 73% across the portfolio.
