 Precious Metal Refinery

Context / Scope of project

The Client, a major precious metals refinery and smelter, asked PIP to help identify improvement opportunities focused initially on cost reduction, as well as help them establish a Continuous Improvement function at the company.

They were under pressure to cut costs and while many initiatives had been carried out in the past, they did not have a system that would ensure sustained and continuous improvement. In particular a headcount reduction project done 5 years ago with another consulting firm was continuously mentioned as a bad example of consultant involvement. After 2 years the headcount was at an even higher level than before the exercise and many of the retrenched employees were working at higher cost as contractors.

There was a strong belief within the company that many processes were broken, but because of the complexity of the business and lack of fact-based and profit-focused analysis, the specific gaps and their magnitude were not clear.

Improvement initiatives were often politically and technologically motivated (improvement was normally associated with spending capex on the latest gadget, rather than improving what was already in place) with almost no real business case backing. The infrastructure, tools and skills for sustainable continuous improvement did not exist.

Our brief was to help identify the improvement potential, implement the highest value ideas, and train an internal Continuous Improvement team which would continue driving improvement long after we were gone.

PIP and client achieved:

(Refinery)

  • 40% reduction in inventory in 6 months
  • 50% reduction in average throughput time
  • 50% reduction in excess metal given away to guarantee weight

(Smelter)

  • 9% increase in smelter throughput by eliminating downtime due to no feed
  • > 40% reduction in rework at the arc furnace
  • 7-9% improvement in margin/tonne with sourcing, and introducing KPIs to drive profit

(Overheads)

  • 20% improvement in EBIT
  • 40% reduction in overtime across the site
  • Renegotiated 10 main contracts to reduce purchasing spend in several million ZAR and improve terms
  • 15% reduction in support process headcount

(Overall)

  • >200m ZAR of improvement opportunities identified (more than doubling diagnostic target)
  • More then 100m ZAR cash flowing in 6 months.

What we did:

  • Identified key improvement areas and trained client team to identify, value and prioritise opportunities
  • Developed a company-wide Value Driver Tree model to help management understand the real business drivers
  • Identified interdependencies among departments working in silos and improved communication across them
  • Changed mindset about cost of inventory and lost revenue due to not honouring customer requirements, which historically was not captured anywhere nor regarded as a real cost
  • Changed mindset about recycling and rework, significantly improving throughput in all areas
  • Reduced inventory and product lead times in 40%
  • Switched from large batch to small batch and continuous processes
  • Changed improvement mindset from large capex driven process changes (normally under-delivering) to achievable and sustainable day-to-day improvements (usually over-delivering)
  • Installed checks and controls for various internal processes and relationships with external suppliers
  • Implemented planning and back-up systems for critical processes
  • Streamlined key support processes reducing flow time
  • Re-wired procurement, capex prioritisation and spend, contractor reduction and on boarding processes, overtime approvals processes
  • Implemented a company-wide planning process to improve communication and reduce WIP
  • Trained and structured team capable of driving and embedding Continuous Improvement
  • Established raw material sourcing practices and KPIs which assessed the profitability of various input materials and communicated closely with production.
