12.3 Kaizen Costing
3 min read•august 9, 2024
costing is all about constant improvement in manufacturing. It's like always looking for ways to make things better and cheaper, bit by bit. This approach fits right in with target costing, which sets cost goals upfront.
Both methods aim to cut costs and boost efficiency. Kaizen costing does it through ongoing tweaks, while target costing sets the bar from the start. Together, they create a powerful cost management strategy.

Key Terms to Review (21)
5S Methodology: The 5S Methodology is a systematic approach to workplace organization and standardization that focuses on improving efficiency and effectiveness by maintaining a clean and organized environment. It is rooted in five Japanese terms: Seiri (Sort), Seiton (Set in order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain). By implementing these principles, organizations can reduce waste, improve safety, and foster a culture of continuous improvement.
Activity-based costing: Activity-based costing (ABC) is a method for allocating overhead and indirect costs to specific activities, products, or services based on their actual consumption of resources. This approach provides a more accurate representation of costs by identifying and analyzing the activities that drive costs, leading to better insights for decision-making and cost management.
