RACI Matrix

Project Responsibility Framework

The RACI Matrix defines clear accountability and responsibility assignments across all project roles and key activities. This framework ensures efficient decision-making, eliminates overlap and confusion, and provides transparent communication channels throughout the development lifecycle. Each role's involvement is classified using the standard RACI model where team members are either Responsible for execution, Accountable for outcomes, Consulted for expertise, or Informed of progress and decisions.

Matrix Implementation

This responsibility matrix will be implemented and maintained throughout all project phases to ensure consistent role clarity and effective collaboration.

The Strategist and Delivery Manager jointly maintain overall matrix oversight and update role assignments as project phases evolve.

Regular review sessions will validate that responsibility assignments remain appropriate and effective as the team composition and project complexity change over time.

Clear escalation paths are defined for situations where responsibility boundaries require clarification or conflict resolution.

The following comprehensive RACI matrix defines accountability for all critical project activities across the development lifecycle. Each intersection shows whether a role is Responsible for execution, Accountable for outcomes, Consulted for input, or Informed of progress and decisions.

Decision Making Authority

Strategic Decisions: Strategist maintains final authority on product vision and business alignment, with Delivery Manager ensuring execution feasibility and timeline adherence.

Technical Decisions: Technical Lead maintains final authority on architectural decisions, with Computer Vision Specialist having authority over CV-specific implementations and Machine Learning Engineer leading ML model decisions.

Design Decisions: Designer leads all user experience and interface decisions, collaborating closely with Full Stack Software Engineer for implementation feasibility.

Operational Decisions: Platform Engineer leads infrastructure decisions, while QA Engineer has authority over testing standards and quality gates.

Data Decisions: Data Engineer has authority over data architecture and pipeline design, ensuring scalability and performance requirements are met.

Compliance Decisions: Compliance Specialist maintains final authority on all privacy and regulatory matters, with escalation paths to legal counsel when necessary.

Hardware Decisions: Hardware Engineer leads equipment selection and deployment strategies, coordinating with Edge Computing Engineer for integration requirements.
