Construct A Value Stream Map For New Product Development

Construct A Value Stream Map Vsm For The New Product Developed U

Construct a value stream map (VSM) for the new product developed under section a) and b) using a MS Office program. It should have a supplier at the one end and a customer at the other end, an information flow with minimum one core activity, a material flow with at least five core activities, at least three inventory locations. You should also enter the value added and non-value added times for all core activities and inventories, and determine the ratio of value added and non-value added times b) As part of the VSM that you created earlier, pick at least four different waste forms and identify at least two examples for each of the four waste forms (all together eight examples) Determine at least one root cause for each waste example and recommend at least one improvement action for each of the root causes (all together eight root causes and eight improvement actions) c) For the process that you picked earlier for value stream mapping, construct a production (layout) floor plan (with at least five core activities) using a MS Office program. Determine the location of equipment, personnel, inventory, etc. as well as the flow of materials/goods with their proper names. d) For your product, construct a JIT production flow based on a Kanban Pull system. Label all the elements and activities within the layout, and describe how the pull system works.

Introduction

Developing an efficient production process requires a comprehensive understanding of the current workflow, waste identification, layout planning, and implementing Just-In-Time (JIT) principles. This paper presents a detailed analysis of constructing a Value Stream Map (VSM), identifying waste and root causes, designing a layout plan, and establishing a Kanban-based JIT flow for a newly developed product.

Constructing a Value Stream Map (VSM)

The initial step involves mapping the entire process from supplier to customer. The VSM illustrates the flow of materials and information, helping identify inefficiencies and value-adding activities. The map starts with raw material suppliers and ends with the customer, with critical core activities identified along the way. For this product, five core manufacturing activities include: raw material receipt, cutting, assembly, quality inspection, and packing. Inventory locations are strategically placed between these activities to buffer variability, with at least three inventory points: raw material buffer, work-in-progress inventory, and finished goods storage.

Both value-added and non-value-added times were recorded for each activity. For instance, cutting during 12 minutes out of a total 20-minute process has a value-added time of 12 minutes and non-value added time of 8 minutes. The ratio calculation indicates the efficiency of each step, with some activities showing scope for improvement where non-value added time exceeds value added time.

The information flow is simplified to a single core activity—order entry—which activates the material flow through the process, maintaining a pull system aligned with customer demand.

Waste Identification and Root Cause Analysis

Using the VSM, widespread waste is identified across four categories:

1. Overproduction

- Excess inventory of raw materials. Root cause: inaccurate demand forecasting.

- Overproduction in assembly. Root cause: batch processing to minimize changeover time.

2. Waiting

- Idle time between operations due to unbalanced workloads. Root cause: uneven process cycle times.

- Delays in quality inspection. Root cause: lack of standardized procedures.

3. Transportation

- Unnecessary movement between inventory points. Root cause: poorly planned layout.

- Excess handling of materials during transfer. Root cause: inconsistent storage locations.

4. Defects

- Defective parts identified during final inspection. Root cause: insufficient operator training.

- Rejection of materials from suppliers. Root cause: poor quality control at supplier end.

For each identified waste, improvement actions are proposed—such as improving demand forecasting accuracy, balancing production lines, standardizing inspection procedures, and reorganizing layout for smoother flow.

Layout Design for Production

The proposed layout arranges equipment and personnel optimally around five core activities—raw material receiving, cutting, assembly, inspection, and packing. Equipment such as cutting machines, assembly stations, inspection benches, and packing tables are positioned sequentially to facilitate smooth flow. Inventory buffers are located strategically between stations to buffer variability; for example, raw material storage near receiving docks, work-in-progress between cutting and assembly, finished goods at packing stations.

Proper labeling of storage areas, equipment, and flow pathways enhances operational clarity. Material flow is marked with arrows indicating the path from raw material intake through processing steps to the finished product ready for shipping.

JIT Production Flow with Kanban Pull System

Implementing a Kanban pull system involves assigning Kanban cards to each process stage, signaling when to produce or move materials. The system controls work-in-progress inventory, aligning production with actual customer demand. The layout incorporates two-bin systems at each station, where the lower bin signals the need for replenishment.

Work is initiated only when a Kanban card is received, thus avoiding overproduction. Each station is responsible for signaling upstream processes when capacity is available, ensuring a smooth, responsive flow of materials. This pull system minimizes waste, reduces inventory levels, and improves responsiveness to customer orders.

Conclusion

This comprehensive approach—through VSM development, waste reduction strategies, layout planning, and JIT implementation—enhances operational efficiency. Strategic waste elimination reduces costs and lead times, while layout and pull systems ensure optimal flow and responsiveness. Together, these tools foster lean manufacturing principles, delivering increased value to customers and strengthening competitive advantage.
