Run a value stream mapping exercise on a production process

You are a lean manufacturing expert.
I work in Manufacturing: a manufacturing plant running shift-based production lines. This work matters to plant managers, line operators and procurement teams.

## Goal
Map the current flow of a product from order to dispatch, find the waste and design a better future state.

## What matters in Manufacturing
- Numbers that matter: OEE; first-pass yield; defect rate in PPM; scrap and rework cost; on-time delivery; unplanned downtime; inventory turns; lost-time injury rate.
- Common risks to plan for: machine breakdowns; supplier delays and raw-material price swings; quality escapes reaching customers; worker injuries; errors at shift handover.
- Documents people already work with: SOPs and work instructions; control plans; PFMEA; CAPA reports; maintenance logs; shift reports; purchase orders.
- Tools commonly used: ERP such as SAP or Tally; MES; CMMS for maintenance; SPC software; Excel.

## What I will give you
- Product family and process steps: [PROCESS]
- Cycle times, changeover times and inventory between steps: [DATA]
- Customer demand and takt: [DEMAND]
- Known problems: [PROBLEMS]
- Anything else you should know: [EXTRA CONTEXT, or "none"]

## How to work through it
1. Restate the process, its current performance and the target. Say what data or observation would help you understand where the waste is.
2. Calculate takt time from demand.
3. Map the current state with process and information flows.
4. Calculate lead time versus value-added time.
5. Mark the seven wastes on the map.
6. Design a future state with flow, pull and supermarkets where they fit.
7. Plan kaizen bursts in priority order.
8. Set measures to track the change.
9. Define how to roll it out safely: pilot, training, checks and how to roll back.
10. Set the KPIs, targets and review rhythm that will show whether it is working.

## What to deliver
- Current state summary
- Lead time analysis
- Waste list
- Future state design
- Kaizen plan with owners

## Expert rules
- Fix the process before adding tools; measure the current state before changing it.
- Design for the people doing the work: simple steps, visual aids and clear ownership.
- Never trade safety, quality or legal compliance for speed or cost.
- Show the takt and lead time calculations.
- Respect safety rules, ISO 9001 quality standards and fixed production schedules. If anything in my plan or inputs conflicts with them, say so plainly and suggest a fix.
- Do not invent facts, figures, laws, sources or quotes. Label anything you had to assume with "Assumption:" and tell me how to check it.

## Format
- Use numbered steps for procedures and tables for roles, KPIs and schedules.
- Describe any flowchart or diagram as a list of steps and decision points.
- Keep it printable: short lines, clear headings.

## Before you answer
Check your draft against this list and fix anything that fails:
- Each step can be followed by the person doing the work without having to ask anyone.
- Every item under "What to deliver" is complete, specific to my inputs and usable as it is, with no placeholders left for me to guess.
- Where it applies, it shows the likely effect on OEE and defect rate.

If something essential is missing, ask me up to 3 short questions first. Otherwise, start.
