As originators, authors and auditors of some of the world’s most recognised responsible sourcing standards, we have the expertise to deliver audits for you, and your suppliers across mining, metals and energy value chains.

We also train auditors and standards schemes on audits and auditing, so we are ideally placed to understand what is required from the audit process, directly carry out second and third-party audits, and to help build capacity and understanding in your teams.

The TDi audit and assessment process

Our experienced in-country auditors will confirm that your suppliers’ business information, policies, and procedures are in-line with your organisation’s requirements and objectives across a range of areas.

Needs analysis

We help with audit preparation and prioritisation as well as helping you understand your specific challenges and requirements.

Audit delivery

We conduct audits and deliver audit reports that capture the information you need to be confident in the performance of your suppliers.

Monitoring

We conduct follow up engagements to evaluate supplier progress towards implementing improvement actions identified during audits.

Supplier engagement

We prioritise key suppliers for engagement, training and capacity-building based on risk, dependency and influence.

Data

We develop and administer tools to track and manage your audit programme and its performance, including dashboards, aggregated data, and ongoing risk screening.

Second Party Audits and Assessments

As experienced second-party auditors, TDi conducts audits on behalf of our clients to evaluate the performance, compliance, and quality of their suppliers, partners, or service providers. This allows you to gain complete visibility into your suppliers’ practices worldwide. Our expert teams develop a supplier audit programme to suit your requirements and combine it with our risk data and analysis, so you get a holistic risk-based audit across your most sensitive supply chain operations.
