Implementation Achievements

Project Management

Before Implementation:

The company managed numerous projects, with project initiation scattered across multiple systems—including the contract management system and DingTalk—resulting in fragmented oversight.

Project tasks and deliverables lacked centralized control. Although there was a need to track performance-based working hours, existing tools could not support this requirement.

Project progress relied solely on individual project managers, making systematic progress monitoring impossible. Task assignments and execution milestones were unclear, leading to low engagement from engineers.

After Implementation:

Sub-project codes, inventory reservation numbers, and other key data are now automatically imported from external systems into PLM during project creation, seamlessly linking disparate systems and initiation workflows. This ensures smooth data flow and clear traceability.

Sub-Project Code View

Project execution is now clearly structured and well-organized, with tasks automatically assigned.

Project deliverables and documentation are automatically compiled and marked as complete upon task fulfillment, ensuring completeness and consistency.

Project Manager Interface

Establish a research and development task aggregation view, integrated with the project management dashboard, providing a clear and immediate overview.

R&D Task Aggregation View

Customized performance algorithms and working-hour tracking have been implemented according to YAHAM Optoelectronics’ management requirements. This enables statistical analysis of related outputs from multiple dimensions, providing management with accurate and actionable data to support continuous improvement.

Employee Performance Statistics

Product, Component, and BOM Management

Before Implementation:

Product family categorization was unclear, with a wide variety of finished products lacking systematic classification.

Components and documents were not linked, making it difficult to locate related information.

Reuse and referencing of materials, BOMs, and associated drawings/documents were inefficient and cumbersome.

Material attributes were inconsistently filled out; electronic material management was disorganized, leading to issues such as multiple part numbers assigned to the same item (“one item, multiple codes”).

There was no controlled process for material approval (material qualification).

After Implementation:

An automated product classification view has been established, automatically grouping finished products by business unit, providing a clear and intuitive product portfolio structure.

The BOM now serves as the central link, connecting all data and documents generated throughout the product development process. BOMs can be efficiently created via direct extraction from design software, Excel import, or rapid manual assembly—significantly improving productivity.

Information flows downstream using the BOM as the authoritative source, ensuring real-time, accurate data delivery to downstream departments.

BOM Manager Interface

Standardized and streamlined material characteristic attributes, with strict rules enforced for part numbering and attribute entry. System-driven validation ensures more accurate material information and more efficient control.

Implemented a formal Material Approval Document workflow to effectively manage material certification processes.

Design Software Integration Management

Before Implementation:

Engineers created drawings in design software and then manually compiled corresponding BOMs based on those drawings—an inefficient and error-prone process.

Whenever drawings were revised, the associated BOMs and documents had to be updated manually on an as-needed basis. Without drawing-driven automation, this resulted in redundant data entry and increased risk of inconsistencies.

After Implementation:

Design software now serves as the authoritative source of design data. Standardized design practices are enforced at the source, and BOMs are automatically generated via integrated interfaces—eliminating redundant manual input and significantly reducing errors.

Through seamless integration with design software, components, BOMs, and drawings are managed as a unified dataset. When a drawing is modified, the system automatically triggers updates to the corresponding BOM and parts, eliminating repetitive work and ensuring data consistency across the product development lifecycle.

Process Management

Before Implementation:

Some approval and review processes were conducted offline, which was time-consuming, labor-intensive, and difficult to track or analyze statistically.

There was no centralized oversight of workflows, making process queries and management inefficient and inconvenient.

After Implementation:

Workflows have been standardized and embedded into the system, enabling effective control throughout the process, enhancing cross-functional collaboration, reducing administrative time, improving overall efficiency, and reinforcing standardized management practices.

Processes can now be monitored and queried in real time during execution. Detailed execution records provide valuable data to support continuous management improvement.

Process Monitoring

Change Management

Before Implementation:

The change processes for materials, BOMs, and documents were difficult to trace.

There was no consolidated statistical view of change orders.

After Implementation:

All changes are now centrally managed within the system, ensuring that electronic documents are always up-to-date and valid in real time.

The entire change process is fully traceable, and related data and documents can be accessed on demand.

Change orders can be queried comprehensively, providing clear visibility into the overall status and history of changes.

Change History

Data Permission Management

Before Implementation:

Permissions were controlled through folders, resulting in a disorganized and inconsistent permission management system.

After Implementation:

A robust and well-defined role-based permission framework has been established. Data access is strictly controlled according to user roles, with support for temporary permissions granted via workflows and the ability to define specific permission validity periods.

Drawings and documents are managed online, with granular controls over viewing, downloading, and editing rights—significantly enhancing document security.

All system operations are logged in real time, enabling effective monitoring and traceability of potential security risks.

Permission Rule Management

Log Management

System Integration Management

Through system integration, PLM has been connected with DingTalk messaging, enabling seamless end-to-end business data flow and ensuring accurate data transmission.

Summary:

Through the implementation of PLM, YAHAM Optoelectronics has standardized and institutionalized its product development processes. All product-related information—including documents, drawings, and BOMs (Bill of Materials)—is now centrally managed and integrated. Using the BOM as the core link, all data and documents generated throughout the development process are systematically interconnected. This approach eliminates issues such as multiple part numbers for a single item or a single part number assigned to multiple items right from the design phase, providing management with clear, visual data sources and a solid foundation for decision-making. The PLM system has also enabled seamless end-to-end business data flow, ensuring accurate data transmission and elevating YAHAM’s data standardization to a new level.
