Space utilization methodology.

Two-Plant Case Study

Floor-area re-allocation, executed as a structured 4-step methodology:

01 ·  Product volume & takt time
02 ·  Functional area mapping & coordinates
03 ·  Process flow & cycle times
04 ·  Transportation devices & product capacity

Floor area decomposed into six functional categories — Workstation, Operator, Material, Maintenance, Tools, and Undefined (deliberate flex slack). 5S and standard-work principles drive the actual re-zoning execution.

Outcomes — Photonics plant, Pointe-Claire (Montréal): ~500 m² recovered into controlled zones before expansion. Material travel reduced ~15%. WIP parking reduced ~10%. Standardized aisle widths and designated temp-storage points improved safety (zero blocked egress routes). Payback < 24 months.

Idea Management. Plant-wide program integrating motivation and appreciation into the corporate culture — transparent communication, recognition of contributors, success-sharing routines.

Over a four-year deployment cycle, the program delivered measurable improvements in employee participation, implementation rate, and direct cost savings — sustained through structured monitoring, management buy-in routines, and dedicated training tracks.

5S as a culture, not a checklist. The objective was never zone audits — it was developing a culture of 5S in thinking: quality at the source, process respect, and abnormality visibility. Bronze certification across all lines, Best-In-Class-level sustenance across three years.

Objectives. Problems triggered by the system. Escalated to the right hierarchy. Fixed in a structured way.

I trained shopfloor leaders, support functions, and QC personnel on the A3 methodology — coaching teams on approach selection, reviewing problem-solving efficiency through Leader Standard Work reports, and fostering rigor over reflex.

The discipline is the same whether the problem is a customer complaint, an internal nonconformance, a supplier defect, or a launch-readiness gap: describe → root-cause → solve → standardize. The tools change. The structure does not.

Jishuken workshops apply the same logic to capacity and capability — observation-driven, KPI-anchored, and sustained through standard-work change. Two parallel tracks govern execution, shown below.
