Client Snapshot

A large, diversified service conglomerate

The client is a large, diversified service conglomerate spanning multiple business units and corporate functions. With improvement efforts fragmented across the organisation and no unified problem-solving language, leadership sought a scalable, certification-backed Lean Six Sigma programme to build lasting internal capability — not a one-off training exercise.

The Challenge

Four hurdles standing between the business and sustainable improvement

01Fragmented improvement initiatives across business units with no unified framework or common problem-solving language
02Absence of a structured, data-driven methodology to identify root causes and implement sustainable solutions
03Limited internal capability to independently lead, mentor, or sustain improvement projects at scale
04No formal certification pathway to recognise improvement champions or create accountability for outcomes
Our Approach

Design, deploy, mentor, sustain

A four-phase programme built to turn training into a self-sustaining, certification-backed improvement engine across every function and seniority level.

01

Design

Customised Yellow Belt and Green Belt curriculum aligned to a corporate service environment.

02

Deploy

Training delivered across 12 batches covering diverse functions and seniority levels.

03

Mentor

Hands-on DMAIC project coaching — guiding each participant through a real business problem.

04

Sustain

Project tracking and review cadence established to monitor progress and benefit realisation.

Yellow Belt and Green Belt tracks ran in parallel across 12 batches, with every participant coached through a live business problem before certification — turning classroom learning into measurable, bottom-line impact.

Client Outcomes

A lasting shift in organisational mindset

Beyond the financial returns, the engagement delivered a lasting shift in organisational mindset. Participants across functions developed the capability to independently identify problems, apply structured analysis, and implement data-backed solutions. The organisation now has an internal pipeline of certified improvement practitioners who continue to drive projects with measurable outcomes — building the foundation for a self-sustaining culture of operational excellence.

“From classroom to boardroom — every project delivered measurable value to the business, validating the impact of structured Lean Six Sigma deployment at scale.”
