How Long Assessments Typically Take

Assessment duration varies by system complexity, governance documentation maturity, and Decision Supply Chain completeness.

Indicative Timeline by Organisation Profile

Organisation Profile	Internal Preparation	Assessment Process	Total Elapsed
Seed-stage, single system, limited documentation	2-4 weeks	1-2 weeks	4-6 weeks
Growth-stage, 2-5 systems, partial documentation	4-8 weeks	2-4 weeks	6-12 weeks
Enterprise, multiple systems, established governance	6-12 weeks	4-8 weeks	10-20 weeks

These ranges are indicative. The largest variable is internal preparation quality before assessor engagement.

Assessment Phases

Phase	Activities	Typical Duration
Preparation	Assemble governance documentation, map the Decision Supply Chain, assign accountability, and run dimensional pre-assessment.	2-12 weeks
Evidence review	Assessor reviews submissions, identifies evidence gaps, and requests clarification.	1-2 weeks
Interviews and verification	Assessor verifies documented governance against operating practice.	1-2 weeks
Dimensional scoring	Evaluate all six dimensions, identify multipliers, and document rationale.	1-2 weeks
GBI calculation and reporting	Produce dimensional profile, multiplier analysis, evidence quality assessment, remediation roadmap, and certification determination.	1-2 weeks

What Shortens Duration

• Governance records already organised by evidence category
• Decision Supply Chain map already maintained
• Dimensional pre-assessment completed before assessor engagement
• Tier 1 evidence infrastructure already in place

What Lengthens Duration

• Documentation assembled from scratch
• Unmapped multi-provider or multi-jurisdiction supply chain
• Scope ambiguity across systems
• Legacy contracts without autonomous decision governance terms
• Parallel multi-system assessment start without phased sequencing
