Due Diligence
Redefining Vendor Due Diligence with New Buyer-Side, Program-Based Model designed to deliver supplier audit results up to 50% faster while improving visibility into up to 40% more procurement risk variables.
Supplier Due Diligence
STS evaluates whether a supplier can reliably support project execution across operational, manufacturing, financial, and compliance areas including:
- Operational capability
- Financial and organizational stability
- Quality management systems
- Supply chain and delivery risk
Manufacturing Due Diligence
STS evaluates whether a manufacturing facility can consistently produce at the required quality, scale, and operational maturity needed to support long-term project execution and delivery requirements including:
- Production capacity and scalability
- Factory QA/QC systems
- Process traceability and consistency
- Site-level operational risk
Technology Due Diligence
STS evaluates the underlying technology platform behind a product, helping buyers understand technology maturity, lifecycle behavior, and long-term reliability risk before large scale.
Technologies are often adopted by multiple manufacturers and may reach commercial deployment before long-term performance is fully understood.
- Technology maturity and adoption
- Reliability and degradation risk
- Lifecycle and bankability considerations
- Knowledge failure and modes
Product Due Diligence
STSÂ evaluates a specific product from a manufacturer to determine whether it is technically suitable, reliable, and aligned with project requirements.
Even when products use the same underlying technology, differences in design, materials, manufacturing implementation, and engineering choices can significantly impact long-term performance and durability.
Including:
- Product design and engineering review
- BOM and specification validation
- Reliability and durability assessment
- Datasheet and performance review

Case Study
Short-listing PV Module Suppliers for a U.S. Developer
A U.S. solar developer asked STS to support the selection of PV module suppliers for a long-term purchase agreement. They had already identified 4 potential suppliers and needed STS to (1) validate the list and (2) assess each supplier’s capabilities with comparable data to support internal decision-making.
Challenge
The client’s list didn’t reflect the full range of reliable market options, especially as global supply chains were shifting. They also wanted to:
– Diversify sourcing, including options from India
– Factor in carbon footprint
– Work with a trusted third party able to audit manufacturing sites directly
Solution
STS delivered:
– A tailored procurement strategy and selection criteria
– An independent evaluation of the 4 suppliers
– A benchmark and a ranking based on consistent metrics
Result
The client identified 4 alternative suppliers, improved supply chain sustainability, and aligned with global ESG standards.
