C.4Design and evaluate materiality evidence and stakeholder inputs

Working Draft version 1.1

Purpose and scope

This unit covers the capability to design a proportionate evidence plan for materiality assessment and to identify, evaluate and integrate stakeholder, rights-holder, due-diligence, grievance, risk, operational, financial, scientific, sector and other inputs. It includes deciding when existing processes are sufficient and when targeted additional engagement or specialist evidence is needed. Stakeholder input informs the assessment but does not replace defined criteria or accountable management judgement.

Applied competency statement

Can design and evaluate proportionate stakeholder, rights-holder, due-diligence and other evidence inputs to materiality assessment, including relevance, representativeness, reliability, limitations, confidentiality and the need for additional engagement or specialist evidence.

Boundary and escalation

This unit owns the materiality evidence plan and the design and evaluation of stakeholder, due-diligence and other materiality inputs. F.3 owns general reporting-evidence requirements and sufficiency. The unit does not replace specialist stakeholder or rights-holder engagement, human-rights due diligence, grievance investigation, social research, legal advice or financial analysis.

Key quality risks

Using stakeholder voting as the materiality decision; treating a broad survey as representative of affected groups; relying only on management opinion or readily available internal data; commissioning new engagement without assessing existing evidence; omitting grievance, incident, rights-holder, sector or scientific evidence; double counting repeated inputs; confusing frequency with severity; and exposing confidential, sensitive or retaliatory information.
