Context and challenge
Why the client needed a new approach
A global gold producer with major operations in Australia, including three underground mines and one open pit, was pursuing a core strategic goal: delivering safe, reliable, and cost-effective operations. A key target was to reduce All-In-Cost (AIC) per unit by 10%.
Despite implementing an Improvement Program (IP) to support this goal, their Business Process Review (BPR) efforts were falling short. The existing approach, though established, faced significant challenges:
- Operations worked in silos, with little alignment across the value chain.
- Analysis was qualitative over quantitative, relying on tools like SWOT and risk matrices.
- Initiative overload diluted focus and effort.
- Delivery paths and outcomes were unclear or poorly defined.
- KPIs were weakly linked to AIC impact.
- Implementation compliance was low.
- Transparency on whether real value was being generated was lacking.
- The client needed a structured, data-driven approach to rapidly target value.

The OX Solutions Approach
How we delivered measurable improvement
To address these challenges, OX Solutions applied its Value Chain Optimisation (VCO) methodology, creating an outcome-driven, evidence-based system. Here’s how:
Diagnose & Align
- Conducted Line Balance and Inventory Analysis to identify Value Chain Constraint Nodes.
- Built a calibrated Value Driver Tree (VDT) down to process and equipment level to pinpoint constraints and levers with the greatest AIC impact.
Root Cause Analysis
- Analysed constraint levers across all nodes to uncover true root causes, not just symptoms.
- Provided financial clarity on issues such as over-budget maintenance, inflation effects, and underutilisation.
Collaborative Problem Solving
Hosted Idea Generation Sessions (IGS) with cross-site teams to:
- Align on performance realities and root causes.
- Define and prioritise highest-impact problems.
- Generate, evaluate, and prioritise initiatives in the context of AIC cost impact.
Leadership Alignment on Targets & Initiatives
- Quantified initiative value using the VDT
- Developed and approved Business Critical Initiatives (BCIs) with full charters: owner, sponsor, KPIs, resources, and workplans.
- Secured leadership commitment to program targets.
Execution & Governance
- Consolidated BCIs into a governed, transparent program of work, with S-curve tracking for value release and resource alignment.
- Embedded a culture of visibility, accountability, and cross-department alignment.
The Outcome
Clarity, value, and cultural transformation
Performance clarity, value realisation, cultural shift.
Focus & Simplicity
Reduced initiative overload—5–8 high-impact BCIs per operation, laser-focused on the constraint.
Impact-Driven Execution
Each initiative tied to a KPI, measurable in AIC cost, with tracked progress.
Transparency & Compliance
Implementation compliance soared; leadership gained full visibility of progress and value delivered.
Cultural Shift
The client developed a clear awareness of their Value Chain Constraint and its drivers. A culture of subordination to the constraint—a cornerstone of VCO—began to take root.
Strategic Next Step
Laid the groundwork for a tailored Operating Philosophy at each site, deepening VCO maturity.
This case demonstrates how OX’s Value Chain Optimisation approach transforms not only how value is delivered, but how organisations think.
For the client, success wasn’t just about achieving a unit cost target, it was about clarity, confidence, control, and cultural evolution across operations.
