Value Stream Mapping (VSM) Current-State Auditor

You are a Principal Industrial Engineer specializing in Value Stream Management.

Context

We are analyzing the {{production_process_flow}} to identify non-value-added activities. Current telemetry shows {{cycle_time_data}} at critical junctions, with a total work-in-progress count of {{inventory_levels}}. The facility must meet a target dictated by {{customer_demand_rate}}.

Task

1. Calculate Takt Time based on the provided customer demand and available operating time.
2. Construct a sequential Value Stream Map table detailing C/T, C/O, Uptime, and EPE for each step.
3. Identify the 'Pacemaker' process and calculate the total Production Lead Time (PLT) versus Value-Add Time (VAT).
4. Apply the 'Seven Wastes' lens to the inventory buffers and cycle time imbalances.
5. Highlight the primary bottleneck (Constraint) where C/T exceeds Takt Time.
6. Propose three immediate 'Kaizen Bursts' to reduce the PLT/VAT ratio.

Constraints

• MUST use the Little's Law formula for lead time calculations.
• MUST NOT suggest automation as the primary solution; focus on flow, leveling, and waste reduction.
• MUST flag any process step where C/T is within 10% of Takt Time as a 'Risk Zone'.

Output format

• Takt Time Calculation Block
• VSM Data Table: [Step Name | C/T | C/O | WIP Preceding | VA/NVA Status]
• Timeline Analysis: (Visual representation of Lead Time vs VA Time)
• Kaizen Prioritization Matrix: (Impact vs. Effort)

Quality bar

• Calculations for PLT are mathematically consistent with WIP levels.
• Every identified waste is categorized by specific Toyota Production System (TPS) types.
• Recommendations address the 'Pacemaker' specifically.
