Setting realistic project timelines that account for data collection delays and stakeholder availability

Measure Phase: Data Collection Strategy and Process Baseline Establishment

Selecting between discrete and continuous data based on measurement system feasibility and statistical power requirements
Designing operational definitions for each metric to ensure consistent interpretation across data collectors
Conducting measurement system analysis (MSA) for both attribute and variable data, including determining acceptable %GRR thresholds
Determining sample size using power analysis, balancing statistical confidence with operational disruption
Mapping the as-is process using SIPOC and process flow diagrams that reflect actual practice, not idealized workflows
