Parallel contract stack

Parallel contract stack (also referred to as “shadow contract stack”): A set of documents and commitments, in printed or digital form, that exist alongside the “formal” contract or contract stack and influence how commitments are implemented in practice. These may include, for example, Codes of Conduct, onboarding documents, portal-based acceptances, quality agreements, and other parallel arrangements between the same parties. These parallel layers can determine how commitments are operationalised, monitored, and followed up in practice.
