Lean Wins
How the Last Planner® System cuts waste on Malaysian sites
The best-laid Gantt chart rarely survives first contact with the site. Crews arrive, prerequisites slip, and “urgent” re-sequencing shreds productivity. Enter the Last Planner® System (LPS)—a lean-construction method that pulls work only when the frontline is truly ready. When used well, LPS has trimmed weekly plan failures from 45 % to below 20 % on local jobs, turning chaos into flow.
Why lean matters right now
CIDB’s Construction 4.0 Strategic Plan names lean practices as a pillar for doubling industry productivity by 2030, yet a 2024 university survey found lean tools “still unpopular” among Malaysian contractors. With labour costs climbing 18 % since 2022 and margin pressure from fixed-price tenders, cutting process waste is becoming the only reliable profit lever.
Last Planner® in one minute
Developed by Ballard & Howell, LPS replaces top-down scheduling with five pull-based levels:
Master schedule (milestones)
Phase planning (milestone pull-backs)
Look-ahead (six-week constraint removal)
Weekly work plans (commitments from “last planners”)
Percent-plan-complete (PPC) review (learn-and-fix loop)
The magic is social: trades make promises to one another, not to an abstract bar chart.
Malaysian adoption snapshot
MRT Putrajaya Line pilot – A 2023 study on the underground stations showed average PPC jumping from 54 % to 82 % after eight weeks of LPS coaching; rework tickets dropped 30 %.
Gamuda’s GET Academy roll-outs – All Digital IBS projects now run weekly commitment meetings; the company reports a 12-day average schedule gain on tower cores since 2024.
CIDB workshops – Over 500 site managers completed CIDB’s Lean Construction short course last year, yet post-course surveys admit only 28 % have fully embedded LPS on active projects.
The takeaway: early wins are clear, but sustaining the discipline takes cultural muscle.
Field case: Klang Valley office tower
On a 38-storey commercial build, the main contractor convened a daily “3 p.m. huddle” with foremen around a magnetic LPS board. Constraint-removal tickets (materials, permits, drawings) had to turn green before tasks could move into the weekly plan. Results after three months:
PPC rose from 61 % to 88 %
Scaffold-reuse cycles trimmed RM 380 k of material spend
Non-productive overtime fell 22 %
Variations lodged under PAM were also better defended, as the LPS log formed a real-time evidence trail.
Five-step roadmap for Malaysian PMs
Start with the look-ahead. Even without fancy software, a six-week “traffic-light” spreadsheet highlights blockers you can kill today.
Co-locate the board. Put the planning wall where crews congregate—canteen or hoist lobby—so they own it.
Measure PPC publicly. Post last week’s score in the toolbox area; pride beats policing.
Digitise after habit forms. Only when sticky notes flow should you switch to a CDE plug-in like Touchplan or VisiLean.
Coach the coaches. Train engineers how to facilitate, not dictate; the best LPS sessions feel like crew conversations, not audits.
Global insight worth importing
On Chile’s Santiago Airport expansion, LPS paired with BIM 4D cut average activity variance to ±3 days, driving a six-month early hand-over. The kicker: planners credit weekly root-cause analysis of plan failures—not software—as the game-changer. Malaysian mega-projects can mirror this by dedicating 30 minutes a week to “why didn’t we hit PPC?” before racing into next-week promises.
Pitfalls that still trip crews
Manager-only planning. If supervisors draft the weekly work plan solo, LPS devolves into old-school push scheduling.
Constraint amnesia. Removing today’s blockers is useless if the procurement team isn’t in the room; invite them.
KPI overload. Track PPC and reason-for-variance first. Add schedule float or crew-density metrics later.
Bottom line
The Last Planner® System turns site chatter into dependable promises, shrinking waste without heroic capital outlay. Master the meetings, guard the PPC ritual, and watch Malaysian projects reclaim days, ringgit and reputation. Share this brief with any site lead who’s drowning in re-sequencing chaos—lean wins start with one good plan-complete score.
