Background
South Africa’s Rail Engineering Arm Commits to World-Class
Transnet Rail Engineering is the engineering division of South Africa’s national freight logistics group — responsible for the maintenance, upgrade, and overhaul of rolling stock across 8 product-focused businesses, 6 major factories, and 132 depots nationwide.
The programme was named Letsema — a Sesotho word meaning “to plough together.” The name itself signalled the intent: this would not be a management initiative handed down to 13,000 people. It would be built with them.

The Challenge
Scale, Dispersion, and a Reactive Maintenance Culture
Aligning over 13,000 employees across factories and depots spanning the full geography of South Africa presented a coordination challenge that no standard improvement programme could address. Aging locomotives required overhauls that a reactive, inefficient maintenance culture could not deliver cost-effectively. Employee engagement was low, frontline performance inconsistent, and variation in cost, quality, and output high across sites.
The Letsema Approach
MDW at National Scale — To Plough Together
1
Leadership from Day OneSenior leadership involvement from the first day of the programme — not as sponsors observed from a distance, but as active participants in the structured rollout. Regular coaching reviews embedded leadership presence as a programme standard, not an occasional gesture.
2
Daily and Weekly Letsema MeetingsStructured daily and weekly Letsema meetings focused on problem-solving, coaching, and performance visibility. The meeting cadence created the consistent rhythms that converted individual effort into team output — and team output into depot-level and factory-level performance improvement.
3
Lean, Six Sigma, and Visual ManagementMDW® principles integrated with Lean tools, Six Sigma methodology, visual management, and 5S across all sites. Letsema provided the cultural and structural foundation; Lean and Six Sigma provided the technical improvement tools. Neither could sustain without the other.
4
Recognition and Innovation ProgrammesMulti-level recognition and innovation programmes established to stimulate local ownership across all sites. Approximately 250 frontline-driven implementations per month demonstrate what happens when recognition and structured suggestion systems convert employee observation into operational improvement at scale.
5
453 Mini-Business Teams — Covering 12,000+ Employees453 Mini-Business Teams launched across all factories and depots, covering more than 12,000 employees. Each team operated as a mini-business within the larger TRE operation — responsible for its own performance metrics, its own improvement cadence, and its own recognition culture. At this scale, MDW® is no longer a site-level intervention; it is a national operating system. The name Letsema told every employee what kind of transformation this was meant to be.
Starting Challenges
Aging locomotive fleet requiring upgrade and overhaul across a reactive maintenance culture.
Widespread inefficiencies across maintenance and manufacturing sites nationally.
Low employee engagement and inconsistent frontline performance across 132 depots.
High variation in cost, quality, and output between sites with no common operating standard.
Need to align 13,000+ employees across vast geography and eight distinct businesses.
Results
From Reactive Maintenance to Measurable World-Class Performance
3×
Production Throughput
Throughput up to 3× higher in key production areas; wagon production increased from 180 to 196 per cycle as team ownership of output targets drove daily performance improvements.
~400/mo
Quality Detection
Approximately 400 quality detections per month — from a low, ad hoc baseline to a structured, team-owned quality identification culture.
92%
Attendance
Employee attendance improved from 82% to 92% — a 10 percentage point gain reflecting the cultural shift from disengagement to ownership across 13,000 people.
250
Innovations/Month
Approximately 250 frontline-driven improvement implementations per month — the innovation output of a national workforce that had been invited into improvement and accepted.
8%
Wagon Cost Reduction
Wagon manufacturing cost reduced by 8% as teams owned their cost performance through structured daily measurement and improvement disciplines.
453
Teams · 132 Depots
453 Mini-Business Teams live across 6 factories and 132 depots — the most extensive MDW® deployment in South African national infrastructure.
“
TRE’s transformation stands as evidence that a large, complex public-sector organisation can shift from reactive maintenance to world-class performance through structured daily improvement and frontline empowerment.

Key Insight
Letsema is the largest MDW® deployment in the CDI library — and it answers the question every enterprise client asks: does this scale? At 13,000 employees, 132 depots, and 453 Mini-Business Teams, the answer is unambiguous. The MBU architecture scales to national infrastructure when leadership is present, rhythms are consistent, and the programme name tells people what they are building together.
