RACI

RACI is a responsibility assignment model used to clarify roles for tasks, deliverables, or processes. The acronym usually stands for Responsible, Accountable, Consulted, and Informed. It is commonly applied in industrial operations, project management, manufacturing process ownership, and cross-functional workflows involving OT, IT, quality, and compliance roles.

Key elements of RACI

In a RACI matrix, each significant activity or deliverable is mapped to stakeholders, with one or more of the following roles assigned:

• Responsible (R): The person or role that performs the work to complete the task or deliverable. There can be multiple Responsible roles, especially in complex manufacturing or validation activities.
• Accountable (A): The person or role ultimately answerable for the outcome and for ensuring the task is completed. There is typically only one Accountable per task to avoid ambiguity.
• Consulted (C): People or roles that provide input, expertise, or approvals before work is done or decisions are made, for example quality, regulatory, or engineering stakeholders.
• Informed (I): Stakeholders who are kept up to date on progress or outcomes but are not expected to provide input, such as operations leadership or external partners.

How RACI is used in manufacturing and regulated environments

In manufacturing, RACI is commonly used to define role clarity for:

• Ownership of production processes, equipment, recipes, and specifications across operations, engineering, maintenance, and quality.
• Changes to MES, ERP, LIMS, or other OT/IT systems, including who raises, approves, and implements changes.
• Execution, review, and approval of batch records, electronic work instructions, deviations, CAPA, and audit responses.
• Data governance activities, such as who is responsible for data entry and who is accountable for data integrity in regulated records.

Operationally, a RACI matrix is often implemented as a simple grid that lists key activities (for example, “approve master batch record,” “release product to ship,” “update SCADA alarm limits”) down one side and roles or departments (for example, Production Supervisor, QA, Validation, IT/OT) across the top. Each cell defines the R, A, C, or I assignment for that combination.

What RACI includes and excludes

RACI focuses on clarifying responsibility and accountability, not on describing detailed work instructions, SOPs, or technical system configurations. It typically:

• Includes: Who performs, approves, is consulted on, or is informed about specific tasks, decisions, or deliverables.
• Excludes: Step-by-step procedures, acceptance criteria, system design details, staffing levels, or organizational charts, although it may reference roles defined elsewhere.

Common confusion

RACI is sometimes confused with:

• Organizational charts: An org chart shows reporting lines, while RACI shows role assignments for specific work activities, which may cut across the formal hierarchy.
• Job descriptions: A job description defines a role in general terms, whereas a RACI matrix connects roles to concrete tasks within a process or project.
• Extended variants: Variants such as RASCI (adding “Support”) or RACIQ (adding “Quality review” or similar) exist, but the core idea is still to clarify responsibility, accountability, and communication expectations.

RACI in compliance and quality contexts

In regulated manufacturing, RACI is often applied to demonstrate clear allocation of responsibilities for activities related to data integrity, validation, deviation handling, CAPA, and document control. It can support internal alignment around who signs, who reviews, and who maintains records in systems such as MES, DMS, and QMS, without itself constituting evidence of compliance or certification.
