Kaizen Skill

Overview

Kaizen - философия непрерывного улучшения через маленькие инкрементальные изменения.

When to Use

Оптимизация процессов
Повышение качества
Устранение waste (потерь)
Повышение эффективности
Культура улучшений

Core Principles

1. Continuous Improvement

Сегодня лучше чем вчера
Завтра лучше чем сегодня
Маленькие шаги каждый день

2. Good Processes = Good Results

Фокус на ПРОЦЕССЕ, не только на результате
Улучши процесс → результат улучшится

3. Go to Gemba

Gemba = "реальное место" (где происходит работа)
- Наблюдай процесс на месте
- Говори с людьми, которые делают работу
- Данные из первоисточника

4. Eliminate Waste (Muda)

7 типов потерь:
1. Перепроизводство - делаем больше чем нужно
2. Ожидание - простои
3. Транспортировка - ненужное перемещение
4. Излишняя обработка - делаем больше чем требуется
5. Запасы - лишние запасы
6. Движение - ненужные движения
7. Дефекты - брак, переделки

PLAN  - Определи проблему, проанализируй, спланируй изменение
DO    - Реализуй изменение (small scale test)
CHECK - Измерь результат, сравни с ожиданием
ACT   - Стандартизируй или корректируй

5 Whys Analysis

## Problem: [Statement]

### Why 1?
Q: Why did [problem] happen?
A: Because [cause 1]

### Why 2?
Q: Why did [cause 1] happen?
A: Because [cause 2]

### Why 3?
Q: Why did [cause 2] happen?
A: Because [cause 3]

### Why 4?
Q: Why did [cause 3] happen?
A: Because [cause 4]

### Why 5?
Q: Why did [cause 4] happen?
A: Because [ROOT CAUSE]

### Solution
Address [ROOT CAUSE] by [action]

Example

## Problem: Customer complaints increased 30%

### Why 1?
Q: Why are customers complaining?
A: Orders arriving late

### Why 2?
Q: Why are orders late?
A: Shipping takes longer than promised

### Why 3?
Q: Why does shipping take longer?
A: Warehouse picking is slow

### Why 4?
Q: Why is picking slow?
A: Items not in expected locations

### Why 5?
Q: Why are items not in locations?
A: No standard restocking process

### ROOT CAUSE: Missing restocking SOP

### Solution: Create and train standard restocking procedure

Value Stream Mapping

Customer Order → Order Entry → Picking → Packing → Shipping → Delivery
     │              │            │          │          │          │
   START         Process      Process    Process    Process      END
     │           Time: 5m     Time: 15m  Time: 10m  Time: 5m      │
     │                                                             │
     └─────────────── Lead Time: 2 days ──────────────────────────┘

Process Time: 35 minutes
Wait Time: 1 day 23 hours 25 minutes
Efficiency: 35min / 2880min = 1.2%

- Wait between order and picking: 8 hours
- Searching for items: 10 minutes
- Rework from errors: 5 minutes

Tips

Start small - маленькие изменения каждый день
Everyone participates - идеи от всех
No blame - фокус на процессе, не на людях
Measure - без метрик нет улучшения
Standardize - закрепляй успешные изменения
Respect - уважай тех, кто делает работу
Never stop - улучшение бесконечно
