• Leadership Modeling : Scrum Master psychological safety demonstration is prerequisite for team development

Scaling Challenges

• Team Size Limits : Techniques optimized for 5-9 member teams may require adaptation for larger groups
• Multi-Team Coordination : Dependencies across teams introduce complexity not fully captured by single-team metrics
• Organizational Alignment : Team-level improvements may be constrained by broader organizational impediments
• Stakeholder Education : External stakeholders require education on probabilistic planning and team development concepts

Measurement Limitations

• Quantitative Bias : Over-reliance on metrics may overlook important qualitative team dynamics
• Gaming Potential : Teams may optimize for measured metrics rather than underlying performance
• Lag Indicators : Many important outcomes (psychological safety, team cohesion) are delayed relative to interventions
• Individual Privacy : Balancing team insights with individual confidentiality and psychological safety
