How we designed a GMT-mapped global support model across four regional centres — achieving continuous 24/7 coverage by coordinating what we already had rather than hiring what we didn't.
Tyco/JCI's global technical support operation covered customers across North America, EMEA, and APAC — but the coverage model was fundamentally regional. Each centre operated on its own hours, and when those hours ended, customers in other time zones waited.
The mandate was clear: achieve genuine 24/7 coverage. The constraint was equally clear: no additional headcount. The solution had to come from coordinating what already existed across four regional centres — not from building something new.
The Follow the Sun model works by mapping shift start and end times across regional centres to GMT, then designing handoff points that ensure no gap in coverage. As one centre's shift ends, the next centre's is already live and briefed on active cases.
The four regional centres in the model:
Opened coverage for the Asia-Pacific region and bridged overnight into the EMEA morning window.
Received handoff from Shanghai, covered European business hours, bridged into the UK afternoon.
Overlapped with Echt for European peak hours, then bridged into the North American morning.
Covered the full North American business day and closed the loop back into the Shanghai overnight.
The handoff protocol required each centre to document active cases, escalations in progress, and any anomalies before their shift ended — ensuring the incoming centre had full context without a voice briefing across time zones.
Designing the coverage model on a spreadsheet took days. Implementing it took months — because the telephony system and reporting engine both needed to be rebuilt from the ground up to support cross-regional routing.
Telephony reprogramming was the most technically complex element. The phone system needed to route incoming calls to the active regional centre based on time of day — automatically, reliably, and with fallback logic for when a centre was unexpectedly unavailable. This required working with the telephony vendor to rebuild routing rules that had previously been entirely static.
Reporting engine rebuild was equally critical. The existing reporting infrastructure tracked performance by centre in isolation. To manage a Follow the Sun model, you need cross-regional visibility — volume by time of day, handoff success rates, escalation patterns that span multiple centres. None of that existed. We built it.
The handoff protocol is everything. A Follow the Sun model is only as good as its handoffs. If the incoming centre doesn't have full context on active cases, they spend the first hour of their shift reconstructing what the previous centre already knew. Standardise the handoff document before go-live.
The systems are the project. Most people think Follow the Sun is a scheduling exercise. It's actually a systems integration project. If your telephony can't route by time of day and your reporting can't aggregate across centres, the model exists on paper and nowhere else.
Culture follows structure. Getting teams in four countries to think of themselves as one continuous operation — rather than four separate centres that occasionally pass work to each other — took longer than the technical implementation. The handoff protocol, the shared reporting, and the cross-regional performance conversations were what built that identity over time.
