Lean Six Sigma in Service & Customer Support

Lean Six Sigma in Service & Customer Support: Why It Matters

Queues, repeat contacts, and guess-work drain staff time and customer trust. Lean hunts wasted steps; Six Sigma hunts defects and variation.

Response time down 85 % at a financial-services help desk after a six-week DMAIC sprint. – Six Sigma Daily
First-call resolution up to 93 % in eight weeks, ending callbacks. – isixsigma.com
Average handle time cut 35 % (20.8 → 13.5 min) when a remote call center fixed its dual-screen gap. – Texas Lean Six Sigma

Lean Tools Every Support Team Can Use

Value-stream map ticket-to-resolution — expose waits between tiers.
Kanban limits — cap open tickets so blockers surface fast.
5S the knowledge base — prune stale articles; label the rest.
Obeya wall (digital) — one board for SLAs, backlog, and daily issues.

Six Sigma Methods for Service Metrics

Metric	What to Track	Why It Helps
First-call resolution	Solved on first contact ÷ total contacts	Direct CX impact
Average handle time	Talk + hold + after-call work	Exposes rework
Ticket response time	Minutes to first reply	Reveals queue health
Customer effort score	Survey score per case	Links fixes to perception

DMAIC takes each metric from baseline → root-cause → pilot → control.

Lean Six Sigma in Service & Customer Support: Step-by-Step Start-Up

Pick one pain point — e.g., response time.
Map the flow — every click, hand-off, and wait.
Tag steps — value-add, required, waste; delete pure waste.
Baseline numbers — minutes, %, $, CSAT.
Analyze causes — 5 Whys, Pareto, regression.
Pilot fixes — one queue or product line.
Control — SOPs, dashboards, weekly audits.
