Reducing Inventory Waste by 30% Through One-Piece Flow Implementation
Implementing a one-piece flow production system, supported by improved maintenance and optimized material handling, can significantly reduce inventory waste in spare part manufacturing.
JIEMS (Journal of Industrial Engineering and Management Systems) · 2019
Key Findings
- 01Inventory was identified as the dominant waste in the spare part production process.
- 02Root causes of inventory waste included machine breakdowns, inefficient material handling, suboptimal machine layout, and batch production.
- 03Implementing a one-piece flow system and investing in maintenance resources were recommended solutions.
Application
Design takeaway
Rethink production systems to favor continuous flow over batch processing and invest in proactive maintenance to minimize disruptions and reduce work-in-progress inventory.
How to apply
Conduct a Value Stream Mapping exercise for your production process, identify the most significant waste using a quantitative assessment, and then use a Fishbone diagram to pinpoint the root causes before implementing targeted solutions like one-piece flow or improved maintenance schedules.
Project actions
- 01When analyzing your design project, think about the entire lifecycle and identify potential 'waste' in materials, energy, or time.
- 02Use tools like VSM or process flowcharts to visualize your design or production process and spot inefficiencies.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Application of established lean manufacturing tools.
- +Systematic approach to waste identification and root cause analysis.
- +Practical recommendations for process improvement.
Limitations
The specific tools and techniques used (VSM, WAM, Fishbone) might require significant effort to implement accurately. The proposed solutions may involve capital investment.
Reliability & validity
The reliability of the findings depends on the accurate application of VSM and WAM. Validity is supported by the use of established tools like the Fishbone diagram for root cause analysis. However, without a control group or long-term follow-up, the causal link between the proposed solutions and sustained improvement might be limited.
Think critically
To what extent can the principles of one-piece flow be applied to highly customized or low-volume production environments, and what adaptations would be necessary?
Design Principles
"Minimize Work-In-Progress (WIP) by optimizing process flow and ensuring equipment reliability."
Excessive inventory is a major source of waste in manufacturing, tying up capital and increasing the risk of obsolescence. By analyzing and eliminating the root causes of inventory buildup, such as machine downtime and batch production, companies can streamline operations, improve efficiency, and gain a competitive edge.
What This Means for Your Design
This study shows that making too many parts at once and having machines break down causes a lot of wasted parts sitting around. By making parts one by one and fixing machines better, companies can save money and be more efficient.
How to use in your project
- 1.Reference this study when discussing methods for identifying and reducing waste in your design project's production or operational phases.
- 2.Use the VSM and Fishbone diagram methodologies as examples of how to analyze problems in your own design process.

Paragraph starter
This research highlights the critical role of lean manufacturing principles in optimizing production processes. By employing Value Stream Mapping and the Waste Assessment Model, the study identified inventory as a significant waste in spare part manufacturing. The subsequent use of a Fishbone diagram revealed that machine breakdowns and batch production were primary contributors. The proposed solutions, focusing on a one-piece flow system and enhanced maintenance, offer a practical framework for reducing waste and improving operational efficiency, a principle directly applicable to streamlining the production of designed artifacts.
