Cognitive Load Assessment Skill

When to Use This Skill

Use this skill when:

• Cognitive Load Assessment tasks - Working on measure and manage team cognitive load
• Planning or design - Need guidance on Cognitive Load Assessment approaches
• Best practices - Want to follow established patterns and standards

Overview

Measure and manage team cognitive load to optimize productivity and sustainability.

MANDATORY: Documentation-First Approach

Before assessing cognitive load:

1. Invoke docs-management skill for cognitive load patterns
2. Verify concepts via MCP servers (perplexity)
3. Base guidance on cognitive load theory and Team Topologies

Cognitive Load Theory for Teams

Three Types of Cognitive Load:

Intrinsic Cognitive Load

INTRINSIC LOAD: Inherent complexity of the domain

Sources:
• Business domain complexity

Germane Cognitive Load

GERMANE LOAD: Productive learning and growth

Sources:
• Learning new technologies
• Skill development
• Innovation work
• Process improvement
• Mastering the domain

Management Strategies:
• Protected learning time
• Conference attendance
• Hackathons
• Mentoring programs
• Stretch assignments

Assessment Questions:

□ How much innovation work?
□ Are people growing skills?
□ Is knowledge being shared?
□ Is there time for experimentation?

Cognitive Load Assessment

Assessment Framework

Team Cognitive Load Formula:

TOTAL LOAD = Intrinsic + Extraneous + Germane

HEALTHY: Total Load < Capacity
STRESSED: Total Load ≈ Capacity
OVERLOADED: Total Load > Capacity

Capacity Factors:
• Team size
• Experience level
• Tool quality
• Process maturity
• Support availability

Assessment Questionnaire

Rate each item 1-5 (1=Low load, 5=High load):

INTRINSIC LOAD (Domain Complexity)
□ ___ Business domain complexity
□ ___ Number of systems owned
□ ___ Integration complexity
□ ___ Stakeholder coordination
□ ___ Compliance requirements
Intrinsic Score: ___/25

EXTRANEOUS LOAD (Unnecessary Complexity)
□ ___ Tooling and infrastructure friction
□ ___ Manual processes and deployments
□ ___ Technical debt burden
□ ___ Waiting time for dependencies
□ ___ Context switching frequency
Extraneous Score: ___/25

GERMANE LOAD (Learning & Growth)
□ ___ New technology adoption rate
□ ___ Process change frequency
□ ___ Skill development demands
□ ___ Innovation expectations
□ ___ Documentation/training work
Germane Score: ___/25

TOTAL COGNITIVE LOAD: ___/75

Interpretation:
< 30: Low load (capacity available)
30-45: Moderate load (sustainable)
45-60: High load (at risk)
> 60: Overloaded (unsustainable)

Domain Complexity Assessment

Domain Complexity Matrix

Team-Domain Fit

Domain Size Assessment:

SMALL DOMAIN (Team can fully own):
• Limited bounded context
• Clear boundaries
• Manageable complexity
• 5-9 person team appropriate

MEDIUM DOMAIN (Stretching team limits):
• Multiple sub-domains
• Some complexity
• Some dependencies
• May need splitting

LARGE DOMAIN (Team overloaded):
• Multiple bounded contexts
• High complexity
• Many dependencies
• MUST split into multiple teams

Workflow

When assessing cognitive load:

1. Gather Team Input: Survey or interview team members
2. Score Each Type: Rate intrinsic, extraneous, germane
3. Identify Hotspots: Where is load highest?
4. Analyze Causes: Why is load high?
5. Prioritize Reductions: Focus on extraneous first
6. Plan Actions: Specific improvements
7. Track Progress: Reassess periodically
