    DORA Details

    What It Is

    DORA (Regulation (EU) 2022/2554) is an EU regulation enhancing digital operational resilience in finance against ICT risks like cyberattacks. It targets 20 financial entity types and critical third-party providers across 27 member states, using a proactive, risk-based, proportional approach.

    Key Components

    • **ICT Risk ManagementFrameworks for identification, protection, detection, response, recovery.
    • **Incident Reporting4-hour alerts, 72-hour updates, 1-month analyses for major events.
    • **Resilience TestingAnnual basics, triennial TLPT.
    • **Third-Party OversightDue diligence, monitoring, ESA supervision of CTPPs.
    • **Information SharingThreat intelligence mechanisms.

    Why Organizations Use It

    Mandatory for compliance, avoiding 2% turnover fines. Bolsters resilience, reduces systemic risks, builds trust amid rising threats like ransomware (74% affected). Enables harmonized operations, cybersecurity innovation.

    Implementation Overview

    Gap analyses, policy development, tool deployment, training. Applies EU-wide to ~22,000 entities; in full effect since January 2025. Ongoing supervisory reporting, no formal certification.

    Six Sigma Details

    What It Is

    Six Sigma is a de facto industry standard and disciplined methodology for process improvement, originating at Motorola in 1986, with partial formalization in ISO 13053:2011. It focuses on reducing process variation, preventing defects, and achieving high-quality levels (3.4 DPMO) through data-driven decisions. The core approach is the DMAIC cycle (Define, Measure, Analyze, Improve, Control) for existing processes and DMADV for new designs.

    Key Components

    • Structured DMAIC/DMADV phases with mandatory deliverables like project charters, SIPOC maps, and control plans.
    • **Belt hierarchyChampions, Master Black Belts, Black Belts, Green Belts.
    • Statistical tools (Gage R&R, DOE, SPC) and metrics (sigma levels, DPMO).
    • Governance via tollgates, roles, and certification (e.g., ASQ CSSBB).

    Why Organizations Use It

    • Drives financial savings (e.g., GE $1B+), customer satisfaction, and risk reduction.
    • Voluntary but strategic for competitiveness; integrates with Lean/ISO.
    • Builds data-driven culture and leadership capability.

    Implementation Overview

    • Phased rollout: sponsorship, training, project portfolio, DMAIC execution.
    • Applies to all sizes/industries; requires training, governance, audits.
    • Certification via bodies like ASQ; ongoing sustainment via SPC.
