Regarding the product / product preparation method of the product life cycle management system, the current plan is that the number of projects undertaken by each unit is increasing, and the pre-research, development, and production of model products involve a wide range of departments. The project management method using traditional means is increasingly backward compared with the current increasingly standardized and standardized project management. It is increasingly important to strengthen the information management of projects. With the development and progress of the industry, some demand defects have also begun to appear; However, the current schemes usually have the following problems: (1) decentralized management of project elements; (2) large span of project process control and fragmented planning data at all levels; (3) inconsistent project management standards, different management granularities, and low standardization and regularization; (4) lack of overall perspective in project planning, making it difficult to reflect the company's overall advantages and overall value; (5) lack of effective control measures for changes and baselines in project plans, making them difficult to trace and audit. (6) inconsistent relationship between projects and contracts, making it difficult to fully implement cost sharing; (7) inconvenient to query the funds for pre-research projects, making it difficult to monitor and control the implementation process in real time; (8) omissions in project content items during project implementation; (9) weak matrix project management methods, with weak resource control; (10) long project information transmission time, and delayed decision-making and problem control; (11) project process control mainly relies on reporting or active inquiry, with subjectivity being stronger than objectivity; (12) low project visualization, making it difficult to monitor and control the implementation process in real time; (13) lack of sharing channels for project information, making it difficult for departments to collaborate, and complex coordination routes. Summary of the invention

Therefore, a rolling plan model is adopted, that is, the near-term plan is decomposed in detail, and the long-term plan is roughly decomposed. This requires standardization of the rolling plan model. The plan granularity is divided into three levels: detailed, finer, and coarser. The granularity of the plan is combined with the plan level specification. Coarser means decomposing the first-level plan of the project, finer means decomposing the second-level plan of each business department, and detailed means decomposing the third-level plan and implementing the executable plan with responsibilities for specific resources.

[0010] The product life cycle management method described in the present invention has a further preferred technical solution that the method adopts plan feedback with full traceability: the departments and personnel responsible for the plan nodes report progress to the project management department; the progress information includes the actual progress of the task, including the actual start time, actual completion time, completion percentage, estimated completion time, progress description; the completion status of the deliverables, problems and risks of the project, and attachments can be uploaded for supporting evidence; the task progress tree is summarized layer by layer on the WBS at all levels and the entire project; when the system management personnel or relevant leaders inquire about the project progress, the completion status of each task is traced in real time.

[0011] The product life cycle management method described in the present invention has a further preferred technical solution that the method adopts a plan change based on process control: the actual execution of the plan may produce deviations, and the plan needs to be adjusted and changed in a timely manner. When the subordinate cannot complete it on time, it is necessary to submit a change application to the competent department of the superior plan. If the application does not exceed the time requirement of the upper-level competent department, the competent department can directly approve the change. If it exceeds, it needs to be submitted to the higher-level competent department for approval, and so on, until the competent department of the project; Project resource planning and multi-project resource scheduling: Through the overall planning of the company's human resources and equipment resources, various types of resources are optimized and scheduled on the basis of project resource planning, so as to improve the rational level of allocation of various types of resources for the project; comprehensively improve the supervision and control capabilities of project decision-makers and management agencies at all levels on the planning, progress, cost, and resource allocation of the project, and focus on monitoring the allocation and conflicts of key resources; provide a solid data foundation for business target management, department and employee performance management, so as to make full use of resources and maximize resource value.

[0012] The product life cycle management method of the present invention has a further preferred technical solution that adopts the project budget as the basis to carry out three-stage project cost control: after sorting out, analyzing and optimizing the current project cost status, the project cost is predicted in advance, controlled in the process and analyzed afterwards based on the cost account + project budget; The product life cycle management system connects project budget, project financial accounting, and project funding analysis information on a unified platform, organically combines budget formulation with project work, and manages the actual expenditure of the project, building a three-stage target control system for project funding management, including pre-control, in-process control, and post-control, providing leaders, project managers, and related business departments with project funding management information throughout the life cycle, improving the timeliness and accuracy of funding disbursement, and improving the work efficiency and effectiveness of the business departments and positions involved; Communication management throughout the entire project management process: Good communication is the basic guarantee for project success, and the management process requires a lot of communication; through the standardized and normalized communication management module of the product life cycle management system, the efficiency of project information communication is improved to ensure efficient communication among project team members; the product life cycle management system provides a unified standard communication platform for all stakeholders of the project. In the shared platform, project briefings, meeting information and meeting action items, project issues and other project-related information and materials can be quickly and conveniently obtained, published, and transmitted, so as to grasp the project progress and major issues in real time.

[0013] The product life cycle management method of the present invention has a further preferred technical solution of adopting dynamic risk management of the project life cycle: the product life cycle management system supports a complete project risk management system, continuously carries out project risk identification, risk analysis, risk assessment, risk response and risk monitoring activities during the project life cycle, and focuses on risk monitoring and mitigation measures effect tracking, so as to obtain the maximum product guarantee with the minimum risk management cost, control the risk within the tolerance range, and achieve the maximum security and economic benefits for the project and the enterprise; Fully integrated with existing business management systems: The product lifecycle management system is the top-level system for product development management. It needs to be integrated with other systems to build a complete project management data system to achieve comprehensive coverage of project management elements. On the other hand, it can also achieve all-round real-time extraction of various data during the project process to provide data support for leadership decision-making. Business systems integrated with the product lifecycle management system include: portal system, MDM system and ERP system. Based on workflow, all business processes of project management are streamlined, normalized and standardized: the product life cycle management system has a built-in workflow function module; the workflow module uses a standardized business data interface or form. After the operator completes the business operation, he can initiate process approval. The product life cycle management system will automatically flow down according to the pre-defined process. The next level of approvers will receive relevant information and can modify, track, manage, query and monitor as needed.

DETAILED DESCRIPTION

[0019] The specific technical solutions of the present invention are further described below to help those skilled in the art further understand the present invention without limiting the rights thereof.

[0020] Example 1, reference Figure 1 -15. Product life cycle management method.

[0021] 1) Standards and specifications Standards and specifications are the premise and foundation for realizing product data integration, exchange and sharing, and are the technical basis for regulating and guiding the orderly development of R&D work. Establish a standardized system for 3D digital products that meet the requirements to improve the accuracy of design, simulation analysis and verification, and the use of 3D models, establish 3D digital prototypes that meet the requirements, and perform 3D digital assembly. Digital design and management Digital design includes data management of three-dimensional innovative design and R&D processes, standardizing product R&D processes, and building a unified product life cycle management system platform; using three-dimensional CAD software as a product design tool, establishing simulation analysis and simulation processes covering the entire life cycle of R&D products, and in accordance with corporate R&D quality control standards, realizing various data management, process management, and change management during the entire system application process.

[0022] 2) Digital technology Establish 3D-based process design and management, conveniently accept design data, realize the conversion of process BOM and 3D process design, realize smooth product process through process data management, process control, visualization, etc., and realize virtual verification of product assembly and production, laying the foundation for digital factory.

[0023] 3) Digital Manufacturing It realizes integration with ERP and MES systems, provides accurate data to downstream, ensures data consistency and accuracy, and provides a basis for workshops to display 3D data and processes.

[0024] 4) Based on project groups, realize unified coordination and management of multiple projects in the enterprise A project group is a group of intrinsically linked projects that are classified and combined according to specific strategies and goals, and that are managed through centralized coordination to achieve overall strategic benefits. Based on the project categories of the enterprise, an enterprise-level project group structure can be built in the project management system. Through overall coordination and intensive allocation of the enterprise's existing resources, coordination and optimization between project groups can be achieved, and cluster benefits can be obtained. Figure 1 .

[0025] 5) Rolling plan preparation with top-down decomposition and near-term details Establish a product life cycle management system with a standard management system to achieve a complete closed-loop process management of online multi-level decomposition, issuance, execution, feedback, and monitoring of project management plans, ensure transparent plans, transparent execution results, and real-time and accurate statistical results, so as to improve the refinement level of project plan management. Figure 2 .

[0026] For long-term complex projects, it is impossible to fully and detailedly decompose the project WBS at one time, so a rolling plan model is adopted, that is, the near-term plan is decomposed in detail and the long-term plan is roughly decomposed. This requires the standardization of the rolling plan model.

[0027] The following figure is an example of standardizing the rolling plan. The plan granularity is divided into three levels: detailed, relatively fine, and relatively coarse. The granularity of the plan is combined with the plan level specification. The relatively coarse one is the first-level plan of the project, the relatively fine one is the second-level plan of each business department, and the detailed one is the executable plan that is decomposed into the third-level plan and the responsibility is implemented to specific resources (executors). Figure 3 is a schematic diagram of the rolling plan.

[0028] 6) Fully traceable plan feedback The departments and personnel responsible for the planned nodes report progress to the project management department. The progress information includes the actual progress of the task (including actual start time, actual completion time, completion percentage, expected completion time, progress description, etc.), the completion status of the deliverables, the problems and risks of the project, etc., and attachments can be uploaded for supporting evidence. The task progress tree is summarized layer by layer on the WBS at all levels and the entire project. Figure 4 This is a diagram of the execution status of the case project plan.

[0029] When system administrators or relevant leaders inquire about project progress, they can trace the completion status of each task in real time.

[0030] 7) Plan changes based on process control The actual implementation of the plan may lead to deviations, and timely adjustments and changes to the plan are required. When the lower level cannot complete the work on time, it is necessary to submit a change application to the competent department of the upper level plan. If the application does not exceed the time requirement of the upper level competent department, the competent department can directly approve the change. If it exceeds the time requirement, it needs to be submitted to the higher level competent department for approval, and so on, all the way to the competent department of the project. Figure 5 Plan change diagram based on process control.

[0031] 8) Project resource planning and multi-project resource scheduling Through the overall planning of the enterprise's human resources and equipment resources, the optimization and dispatch of various resources are carried out on the basis of the project resource plan, and the rational level of the allocation of various resources for the project is improved; the supervision and control capabilities of the project decision-making level and management agencies at all levels on the project's plan, progress, cost, and resource allocation are comprehensively improved, and the allocation and conflict of key resources are monitored and focused; a solid data foundation is provided for business target management, department and employee performance management, so as to make full use of resources and maximize resource value. Figure 6 Project resource scheduling diagram.

[0032] 9) Based on the project budget, carry out three-stage project funding control before, during and after the project After sorting out, analyzing and optimizing the current project cost status, this plan adopts the method of expense items + project budget to conduct pre-forecasting, in-process control and post-analysis of project funds.

[0033] The product life cycle management system connects project budget, project financial accounting, and project funding analysis information on a unified platform, organically combines budget formulation with project work, manages the actual expenditure of the project, and builds a three-stage target control system for project funding management: pre-control, in-process control, and post-control. It provides leaders, project managers, and related business departments with project funding management information throughout the life cycle, improves the timeliness and accuracy of funding disbursement, and improves the work efficiency and effectiveness of the business departments and positions involved. Based on the project budget, the three-stage control reference is realized Figure 7 .

[0034] 10) Communication management throughout the entire project management process Good communication is the basic guarantee for project success, and the management process requires a lot of communication. Through the standardized and normalized communication management module of the product life cycle management system, the efficiency of project information communication can be improved and efficient communication among project team members can be ensured.

[0035] The product life cycle management system provides a unified standard communication platform for all stakeholders of the project. In the shared platform, project briefings, meeting information and meeting action items, project issues and other project-related information and materials can be quickly and conveniently obtained, published, and transmitted, so as to grasp the project progress, major issues and other situations in real time. Figure 8 .

[0036] 11) Dynamic risk management throughout the project life cycle The product life cycle management system supports a complete project risk management system, which can continuously carry out project risk identification, risk analysis, risk assessment, risk response and risk monitoring activities during the project life cycle, and focus on risk monitoring and mitigation measures to track the effectiveness, so as to obtain the maximum product guarantee with the minimum risk management cost, control the risk within the acceptable range, and achieve the maximum security and economic benefits for the project and the enterprise. Fig. 9 .

[0037] 12) Fully integrated with existing business management systems The product life cycle management system is the top-level system of product development management. It needs to be integrated with other systems to, on the one hand, build a complete project management data system to achieve comprehensive coverage of project management elements; on the other hand, it can achieve all-round real-time extraction of various data in the project process to provide data support for leadership decision-making.

[0038] Business systems integrated with the product life cycle management system include: portal system, MDM system, ERP system, etc.

[0039] 13) Based on workflow, realize the process, standardization and standardization of project management The product life cycle management system has a built-in workflow function module. The workflow module uses a standardized business data interface or form. After the operator completes the business operation, he can initiate a process approval. The product life cycle management system will automatically flow down according to the pre-defined process. The next level of approvers will receive relevant information and can modify, track, manage, query, monitor, etc. as needed. The workflow greatly improves work efficiency, realizes the process, standardization, and standardization of various project management businesses, and enhances the core competitiveness of project management.

[0040] The product life cycle management system has a powerful workflow platform and fully considers the business characteristics of project-based enterprises. It is closely integrated with various business modules of project management, and has the characteristics of flexible and practical functions, powerful functions, and simple operation. For example, for the same "project plan release approval" business, Class A projects (i.e. key projects) need to go through four levels of approval, while Class B projects (i.e. general projects) can be released after three levels of approval.

[0041] 14) Statistical analysis of project management business data from multiple perspectives such as project groups, projects, departments, and individuals The product life cycle management system provides a rich variety of business statistical analysis, which can analyze data from multiple dimensions and angles such as project groups, projects, departments, and individuals, and achieve global to local, from multi-project portfolio to single project monitoring, to meet the different data needs of the leadership, project management, department management, and project team members. The data is presented in a variety of ways, including graphics, reports, or charts, which can fully meet business needs, and can be customized according to needs later.
