Sheet Medal & Flexible Design Manufacturing Center of China Electronic Technology group Corporations is a professional design institute owned by China Electronic Technology group Corporations (CETC). Present Sheet Medal Design CAD Center and Flexible Manufacturing Center specialize in design and manufacturing of such sheet medal components as computer case, antenna and etc. With the development of sheet medal flexible design manufacturing center, current design management environment can no longer meet the new demands, which leads to urgent needs for information-based methods to make standard and improve design management. Therefore, enterprise IP will be better protected, production efficiency will be improved and enterprise market competitiveness will be strengthened.

Analysis
Having done research for current design environment in Sheet Medal Flexible Design Manufacturing Center of CETC, we have found the following problems existed in current design data management:

1) Design data lies on manual management, and management is lack of standard with low efficiency.
2) Design environment is lack of security protection, which causes easy data loss and damage.
3) Design process data is controlled by design staff, which leads to ineffective control and grasp of data by the whole enterprise.

In order to help Sheet Medal Flexible Design Manufacturing Center of CETC reach a higher level of design management, shorten product R&D cycle and improves market competitiveness, Top Era Technology Limited provides a solution aimed at the above problems - "DCM Sheet Medal Design Data Version Management System".

Sheet Medal Design Data Version Management Solution
Sheet Medal Design Data Version Management System is achieved through customization for Top Era Technology's DOIT system. The solution includes Data Management and Security Management, two major functions.

Based on centralized management of data, Sheet Medal Design Data Version Management System provides design staff with complete-process data version management functionality. Meanwhile, the system builds an open and secure development design environment for enterprises through complete security measures. Therefore, enterprise design development cycle will be reduced and product design efficiency is improved.

Sheet Medal Design Data Version Management System adopts B/S three-layer mode. The effective separation of application processing by three-layer mode fits more the execution of key jobs as well as new application system that requires re-planning, expanding and re-group. The three-layer mode composed of browser-based standard client configuration and network server eases the installation for the end-user.

Implementation
System implementation adopts scientifically standard ADT method.

Based on the principles of system research implementation method and in accordance with internationally recognized advanced methods, ADT, AcceleratorDOIT, is an accurate implementation method system developed by Top Era Technology. ADT emphasizes on re-useable flow-like production and is able to perform continuous optimization. ADT divides complete implementation process into 6 accurate procedures, meanwhile fully considering key factors that will affect implementation during the whole process.

ADT Implementation
ADI has 6 phases including plan, preparation, project blueprint design, project blueprint implementation, preparation for running, running and support. Among which, project blueprint design and project blueprint implementation are both repeated processes until clients' request are met.

ADT Implementation
• Plan
• During this phase, Sheet Medal Design Center will know the basic infrastructure and main functionalities of information system. This will enable users to better understand the benefits brought by implementing information system. All participants should grasp current enterprise architecture and operational status, as well as what will bring to the enterprise when implementing information system. After this procedure, leader will acknowledge and approve the project and client's confidence will be strengthened.

• Preparation
• Before the implementation of information system, it is a must to understand current enterprise product design overview and to define hidden problems. During this phase, the main task is to build design management model of Sheet Medal Design Center in order to provide a comparison after implementation of information system and to clearly define project scale. Meanwhile, it is necessary to prepare for various resources and technologies of "Design Data Management System".

• Project Blueprint Design
• During this phase, it is a must to define basic scale of design data management system in Sheet Medal Design Center, to confirm detailed project implementation plan, to put project goal in details and finally to confirm business request and description, analysis and optimization of workflow.

• Project Blueprint Implementation
• During this phase, project team must control development process to gradually execute blueprint and finally complete system test, obtaining system confirmation from Sheet Medal Design Center.

• Preparation for Running
• Lots of test running for end-users to complete preparation for system delivery, ensuring system running properly and solving redundancy problem.

• Running and Support
• Making correct system delivery to ensure proper running

ADT's 6 phases are inter-connected with clear goal of each phase, in order to monitor complete process together with Sheet Medal Design Manufacturing Center and ensure system's effective running. ADT also guarantees system development is in accordance with clients' actual requests through client's partly participation in each phase. Broad information-based teaching and training assists system to be delivered properly with high working efficiency.

Conclusion
After implementing "Sheet Medal Design Data Version Management System", Sheet Medal & Flexible Design Manufacturing Center of China Electronic Technology group Corporations achieves the followings:
1) Secure and reliable design environment in enterprise intranet, eliminating access violation and preventing data conflict.
2) Centralized management for various types of design data, enabling design data share and preventing design data loss caused by manual operations.
3) Project-team-level collaborative design support is achieved via branching and merging.
4) Version (process) management of Design data enables tracking and tracing of design process data.
5) Design achievement management increases design reuse, enabling knowledge management and accumulation.
