Abstract: The pump industry shares commonalities with the general machinery industry, but also possesses unique characteristics. Therefore, the implementation of ERP in the pump industry has similar key points to other industries, but also unique characteristics and challenges specific to this industry. Based on an analysis of the characteristics of the pump industry, this paper analyzes in detail the commonalities and challenges of ERP implementation in the pump industry, and proposes corresponding solutions. Keywords: Commonalities; Individuality; Industry Characteristics; Refined Management; System Implementation 1. Introduction The arrival of the era of economic globalization and market diversification requires enterprises to establish efficient, dynamic, and rapid-response systems; informatization is an inevitable choice for enterprises and a powerful tool for enhancing their competitiveness. However, in the process of introducing an ERP system, implementation is an extremely critical yet easily overlooked link. This is because the success or failure of implementation ultimately determines the full realization of ERP benefits. According to incomplete statistics, in all ERP system applications, three situations exist: only 10%-20% successfully implement and integrate the system on schedule and within budget; only 30%-40% fail to achieve system integration or achieve partial integration; and 50% fail. Therefore, fully grasping the key points and difficulties of ERP implementation and adopting scientific implementation methods are crucial for enterprises to successfully implement ERP and achieve their application goals. Furthermore, according to authoritative departments, the domestic pump industry is expected to maintain a growth rate of 11% to 12% over the next 3-5 years. Especially benefiting from the country's proactive policies and the expansion of domestic demand, the continued growth in demand from major sectors of the national economy such as power, steel, and petrochemicals, as well as urban infrastructure construction, will allow China's pump industry to continue developing at a rate 2% to 3% higher than the machinery industry. The rapid development of the pump industry has placed higher demands on the management of pump companies, and enterprise information management systems led by ERP are gradually being applied to pump companies of all sizes; therefore, the analysis of the difficulties in implementing ERP systems in the pump industry and the importance of its success or failure have been elevated to a new level. 2. Analysis of the Characteristics of the Pump Industry A pump is a machine that converts mechanical energy into liquid energy to pressurize and transport liquids. Pumps are the most widely used and common general-purpose machinery in the national economy, widely used in water conservancy and power generation, and especially prevalent in petrochemical production. From an industry classification perspective, the pump industry belongs to the typical machinery and equipment manufacturing industry; from the perspective of the basic type of manufacturing system, it belongs to the typical discrete manufacturing industry, with the production process having the nature of "processing-assembly". 1) Characteristics of Pump Industry Products Pump products have complex structures. Unlike process industries, pump products are not fixed, and their composition changes with market changes. Due to the complexity of the product structure, the design task is heavy. Not only is it necessary to continuously develop new products, but there are also a lot of variation design tasks in the production of old products. Therefore, enterprises are required to have strong product development capabilities, including research capabilities in pump performance, wear mechanisms, wear-resistant materials, etc. Although the production of each product requires the process of blank manufacturing, machining, procurement of outsourced parts, component assembly, and complete machine assembly, there are still significant differences in the manufacturing processes of different products. In addition, pump industry products have another distinctive feature: the materials of pump components change very frequently. Basically, each customer has their own personalized material requirements for the specified components, resulting in most of the products produced by pump companies being disposable. 2) Characteristics of Pump Industry Operation and Management: Customers in the pump industry are concentrated in sectors such as water conservancy, chemical, metallurgy, power, mining, coal, and building materials. Due to the specific characteristics of these industries, a combination of order-based and component-based ordering models is common. Generally, there are overall solutions for large-scale projects, and project-based personalized needs are becoming increasingly urgent. In terms of sales, a combination of regional sales, industry-specific solutions, and standard product sales is employed. 3) Characteristics of Pump Industry Production Management: The pump industry shares commonalities with the general machinery industry, but also possesses its own unique characteristics. Production methods include mass production of standard products as well as small-batch, personalized production. Manufacturing models need to support not only multi-variety and multi-batch production, but also single-piece production, inventory-based production, and project-based personalized production. Product production cycles are long, ranging from 1-2 weeks to over six months. Production planning is difficult to control, leading to frequent changes in the production process; coupled with numerous personalized requirements and high demands for personalized production process management, the production process itself is also difficult to control. 4) Characteristics of Cost Accounting in the Pump Industry: Due to the long sales cycle of pump products, the payment period for some large pump products can be as long as one year or more, making sales profits difficult to analyze. Furthermore, the high degree of personalization in product structure and production processes, especially for project-based large pump products, makes cost accounting particularly complex and difficult to manage precisely, usually requiring post-implementation accounting. 3. Analysis of Common Key Points and Difficulties: There are some common aspects to pay special attention to during the implementation of an ERP system, which are equally important in different industries. 1) Preparation of Basic Data: "Three parts technology, seven parts management, twelve parts data"—this well-known saying in the ERP industry fully illustrates the importance of data in the ERP implementation process. The preparation of basic data is paramount, as it is crucial for ensuring the correct operation of the system. Basic data in ERP includes material codes, bill of materials (BOM), organizational structure, warehouse attribute settings, etc. Before preparing basic data, it is essential to fully instill the importance of basic data preparation in relevant business departments and the implementation team in the information center. In addition, during data preparation, both work efficiency and data accuracy should be emphasized. 1) The completion time for each basic data preparation should be determined in advance, and the execution time and accuracy should be assessed accordingly. 2) Project Implementation Supervision and Feedback Mechanism: When both parties determine the implementation plan and push it forward, if lower-level departments do not follow the requirements or do not fully comply, it will hinder the successful implementation of ERP. Establishing a project feedback and supervision mechanism serves this purpose. Weekly planning and summary meetings are very helpful in assigning weekly tasks, reflecting problems encountered during implementation, and seeking support from various departments. In addition, during the implementation process, try to adopt a "tight at first, loose later" strategy, especially for companies with low execution capabilities; this should be controlled at the beginning of the project, otherwise it will be difficult to control or manage effectively later. 3) Business Process Reengineering and Adaptive Software Function Settings: There will always be some discrepancies between the software vendor's products and the customer's actual needs. ERP systems are based on standardized and normalized business processes; therefore, to successfully implement an ERP system, the company's business processes must be redesigned and optimized. However, any business process reengineering comes at a cost to the enterprise. Therefore, it is necessary to combine the adjustment of software product functions with the enterprise's process reengineering, and choose an optimal point of integration to minimize the enterprise's costs while meeting the requirements of both parties. Of course, necessary reengineering considering the future development needs of the enterprise should still be strongly promoted. 4) Training The importance of training in ERP implementation is well known, and different training content should be organized for different people at different stages of implementation. However, ERP project implementation experience shows that the software company's implementation consultants first train the client company's implementation team, and then they train the enterprise's end users. This two-tiered training method not only reduces the workload of the implementation consultants, but also facilitates the client's later maintenance of the system. In addition, the assessment and reward/penalty after training are also very critical links and must be implemented in practice. 4. Analysis of Personalized Key Points and Difficulties The characteristics of pump companies' products, processes, and orders determine that there are special key points and difficulties in the ERP implementation process of pump companies that need to be treated individually. 1) Material Classification, Coding, and Configuration The complexity of the pump product structure adds a certain degree of difficulty to the material classification in the ERP implementation of pump companies. Material classification can be done by product series, further subdividing each series into finished products, parts, and blanks. Parts can then be further divided into general and non-general components. Alternatively, finished products, semi-finished products, and blanks can be directly categorized into major material categories, with further subdivisions into subcategories and minor categories within each major category. In short, material classification must be based on the company's actual material situation, taking into account factors such as future material category authorization and financial account settings in the system. It's crucial to finalize the classification as early as possible; otherwise, subsequent coding work will be impossible. Since pump companies primarily produce to order, many products and their corresponding codes are one-off. Moreover, as customer needs change, many purchased component codes need to be continuously added. The company needs to assign relevant personnel to quickly master code maintenance. Additionally, frequently changing material information should be placed in configuration information rather than coding, such as adjusting the length of the pumping pipe, adjusting the protective pipe, the manufacturer of the motor and bearings, and the paint color. The material combination information for components in finished products will depend on the specific circumstances. Some pump manufacturers produce six or seven types of components whose materials frequently change, and each component has three or four possible material variations. Through permutations and combinations, the possible material combinations for a single pump component can reach thousands, many of which will never occur. If material combination information is entered into the coding system, a large number of codes will be generated that will never be used, and significant effort will be required to create a Bill of Materials (BOM) for them. If material combination information is entered into the configuration system, the number of material codes will be greatly reduced, and there will be no need to enter a large amount of useless BOM data beforehand; only the later BOM maintenance will involve some workload. 2) Customer BOM: The most significant characteristic of the pump industry is the personalization and diversification of customer orders. This requires the ERP system to generate corresponding sales orders based on customer requirements in the sales management subsystem and configure the corresponding material composition structure (customer BOM) to ensure that there is corresponding BOM data for plan decomposition and subsequent quota-based material requisition. Furthermore, among the personalized needs of customers, some pump product components are mandatory, some are optional, and some are dispensable. Therefore, the software's functional settings need to meet these personalized customer needs. 3) Order Changes and Work Order Adjustments: Statistics show that for some pump companies, changes to sales orders account for as much as 80% of total orders. Types of order changes generally include: ① Changing delivery methods, delivery locations, and other external parameters; ② Increasing the quantity of products in a sales order or adding new products; ③ Decreasing the quantity of products in a sales order, or even canceling the sales order; ④ Changes in the unit price or delivery date of products in a sales order. The first situation is relatively easy to handle. If the order has been approved or broken down and a work order has been issued, a change order can be issued directly to the relevant departments. The second situation requires adding an additional sales order, and the new document must be linked to the original order (e.g., through the same contract number). Then, an MPS (Master Production Schedule) is generated for the new order, and it is broken down and a work order is issued. The third situation also requires the new document to be linked to the original order, but the quantity and amount in the new order must offset the original order. A change order is then used to notify the relevant departments to adjust the work order execution plan. In the fourth situation, when the unit price changes, a new document needs to be linked. If only the delivery date is changed, it requires manual control by relevant personnel during actual production scheduling. 4) Support for Four Production Modes: Due to the complexity of product structure and processing, as well as the diversity of customer needs, ERP systems, while centered on manufacturing, must be based on four production types and supply models: Design to Order (MTO), Production to Order (MTO), Assembly to Order (MTO), and Production to Inventory (MTO). To track these four production modes, project levels can be divided into MPS, products, semi-finished products, and raw materials. Given an order, to support these four production types, it's necessary to control whether different levels of entities carry the corresponding order number, as shown in the table below. 5) Combination of MRP and JIT: The completeness of standard parts, purchased parts, and self-manufactured parts (specifications, materials, quantities, delivery dates, and quality, etc.) directly affects the final assembly schedule and delivery date. Due to numerous unforeseen circumstances (such as urgent customer orders, order cancellations, changes, and other situations), if the assembly schedule fails to meet the plan for any reason, it will lead to on-site waiting and the accumulation of individual parts occupying assembly space. If this cannot be effectively prevented and the plan cannot be adjusted in a timely manner, it will create a vicious cycle. Traditional ERP systems struggle to prevent this phenomenon. Adopting the JIT (Just-In-Time) approach, MRP (Material Requirements Planning) plans, procurement, outsourcing, and in-house manufacturing plans are "pulled" out based on the actual assembly progress. Materials are pre-allocated according to the actual assembly needs in terms of time, location, type, and quantity, and timely delivery is implemented, thus improving the overall compatibility of product assembly. 6) Refined Workshop Management: Refined workshop management mainly involves strengthening the workshop's execution and reporting functions, and recording the occurrence and handling of workshop anomalies. The ERP system should be able to promptly provide feedback on workshop production material requisition and return/replenishment, production process flow records, production output records, finished product inspection and warehousing records, and other relevant information; promptly report the completion status of work center processes and work orders; and promptly record the work center's capacity status before each production scheduling and any anomalies that occur during production and their handling measures. This allows the production department to have a detailed understanding of the entire workshop's production status and the state of the production process, to have a comprehensive grasp of the execution of the issued production plan, and to ensure on-time delivery. 7) Refined Cost Accounting: Currently, many pump companies use outdated raw data for cost accounting, including outdated planned price data and inaccurate time quotas. The planned price accounting method cannot keep up with market changes and cannot monitor real-time costs. Therefore, implementing an ERP system requires that, in terms of refined cost management, the system can adopt multiple accounting methods, such as accounting by order, by product, and by workshop (or even by process), while simultaneously calculating the actual cost of orders or products. This requires that during the collection of cost accounting-related data, reasonable rules for the allocation of wages and manufacturing overhead be defined, and that the system automatically track and retrieve records of product warehousing and component material requisition (return, replenishment) corresponding to the order; for some materials whose actual material cost is difficult to determine, they should be processed according to standard costs. For example, when producing a part of a certain special shape, steel plates need to be requisitioned, and the quantity requisitioned can be processed according to the standard usage. 8) Multi-unit pump components mainly involve multiple units, including steel, cylinder blanks, and rubber strips. However, the use of multiple units differs. For example, there is a stable conversion relationship between the primary and secondary units of steel and rubber strips, which can be controlled by pre-setting secondary coefficients. However, the conversion coefficients between the primary and secondary units of cylinder blanks are variable. It is uncertain how many blanks a cylinder blank can be divided into for machining into semi-finished products, so the primary and secondary quantities must be manually entered. Furthermore, steel includes round steel, channel steel, flat steel, steel pipes, steel plates, etc., each requiring different formulas for calculating conversion coefficients. Also, the specific gravity of ordinary materials differs from that of stainless steel; these are all important considerations. 5. Conclusion: The success or failure of ERP implementation is crucial for the development of any enterprise, especially for the booming pump industry. If a company invests significant human, material, and financial resources only to suffer a failed implementation, it will not only lose money but also miss a valuable opportunity for development, potentially leading to a decline. Therefore, when implementing ERP in the pump industry, it is essential to fully grasp the key points and challenges of implementation, minimize detours, and thus improve the success rate of implementation.
