Performance baseline
Benchmarked OEE, equipment availability, MTTR and MTBF, then used Pareto analysis to identify the failure modes with the greatest operational impact.
Boosting Equipment Uptime in Component Production
Case Study
Boosting Equipment Uptime in component Production
The client was experiencing frequent equipment breakdowns and low uptime—averaging below 80%—across critical ammunition production lines. A reactive maintenance culture, limited visibility into MTTR/MTBF metrics, and high spare part costs were negatively impacting throughput, product quality, and export commitments.
Achieved a significant increase in equipment availability—from 78% to 92%—through structured TPM and preventive maintenance implementation.
Lowered equipment breakdowns by 40%, driven by root cause analysis training, standardized failure reporting, and technician-led improvements.
Saved USD 100,000 annually by localizing critical spare parts sourcing and improving maintenance planning, while also achieving 95% PM compliance.

The challenge
A clear operational constraint with measurable consequences.
The client was experiencing frequent equipment breakdowns and equipment availability below 80% across critical production lines. Reactive maintenance, limited visibility of MTTR and MTBF, inconsistent failure reporting and costly imported spares were affecting throughput, quality and delivery commitments.
The engagement established a clear performance baseline, introduced structured preventive maintenance and embedded practical root-cause problem solving with technicians and operators. Local spares planning and formal maintenance controls were developed alongside the operating team.
Engagement approach
Structured from evidence to sustained control.
The work was organised into three connected stages so that diagnosis, implementation and internal capability developed together.
Reliability system
Introduced daily, weekly and monthly preventive maintenance routines, visual controls, operator-assigned tasks and structured critical-spares planning.
Capability and control
Trained technicians in root-cause methods, formalised failure reporting and established maintenance KPIs to support sustained improvement.
Methods and controls
Practical tools selected for the operating environment.
Methods were applied to support decisions, strengthen internal ownership and create repeatable management controls.

Outcome
The programme moved maintenance from a reactive model towards disciplined reliability management. Equipment availability increased, breakdown frequency fell and the site achieved stronger preventive-maintenance compliance while reducing the cost and lead time of critical spares.
Measured improvement supported by clearer ownership, stronger controls and practical workforce engagement.
Results shown reflect the stated client baseline and engagement scope. Client identity remains confidential, and outcomes may vary according to operating conditions, available data and implementation ownership.
Approach & Execution
Phase 1: Baseline Assessment
Conducted OEE benchmarking and tracked MTTR/MTBF across key assets.
Performed Pareto analysis to identify high-impact failure modes
Phase 2: TPM Strategy Deployment
