What is the GDI assessment procedure?

Our expert audit team will visit you to carry out an assessment. Your Stroma assessor will first audit your written documentation. This is called your desktop (or office) assessment. Then they will undertake a site assessment to cover each type of work. Your assessment will be reviewed on an annual basis to maintain your certification.

What is the Quality Management System?

A key requirement of PAS 2030 is to implement a compliant Quality Management System (or QMS). A QMS defines the processes and procedures followed by your business in the completion of any client or customer work. During the desktop assessment the assessor will audit your QMS documentation and provide an action plan to correct any non-conformities.
