In the enterprise information system project actual combat, the system in parallel is often easier to overlook a stage, but in fact it is the process of enterprise information is a very important stage, on-line business success ERP system plays a vital role. The so-called parallel system, refer to enterprises in the selected ERP software, determine the implementation strategy and schedule information, the organization of human input some or all of the basic data, and then start the test run ERP software projects. In the meantime, businesses, or the original hand accounts continue to run the old software, so that the two systems old and new in a particular period of time synchronization in parallel operation. To test the applicability and reliability of the new system, in order to lay the foundation for later Timberley a stage. Realistically speaking, the system is a more troublesome parallel stage, at this stage, the system can not immediately play an effective, employees and implementation of the staff has a heavy burden, which is basically a need to pay a lot but do not see the results of stage. However, this is the case, at this stage are still seemed more important. Because:
First, before the system selection, only a rough understanding about the performance of ERP software, and no real test. The system parallel phase, the ERP system is a real sense test. Enterprises who may be found at this stage of the ERP system on-line capability and performance of the real advantages and disadvantages.
Second, the system before the on-line enterprise in order to maintain operation, certainly has its own set of hand calculations, or the old software system, businesses can not immediately discard the old system, a "hard landing." Therefore, we must have a transition phase, to carry out a smooth docking of the two systems old and new. Third, the system in parallel stages, in essence, is an ERP system, trial operation. At this stage for the company is still "move forward and attack, retreat and defend", that is, once found to be on the line ERP is fundamentally flawed, you can still take remedial measures without affecting the normal operation of enterprises.
Once the system Timberley, and then exposed the major shortcomings will no doubt bring about loss of business. Since the system in parallel is so important, how do we do to put this phase of implementation is good, the author here, according to where the company's hands-on, where the initiate to make several suggestions.
First, the company's leadership in this difficult stage should be given adequate attention, such attention is not only ideological, but also should be reflected in action. As the parallel phase is arduous, the relevant business personnel should also maintain two sets of accounts, but also to ensure synchronization between, so a larger workload. At this time business leaders must pay attention to the ideological work of front-line operational staff to give them the significance of make it clear to do so, while as much as possible in the human resources staff deployment to ensure the smooth working in parallel.
Second, the specific phase of the system parallel the length of time, as well as a parallel strategy, I believe that all enterprises should be based on units of the original situation, the amount of data size and complexity of business processes, personnel readiness, etc. "conditions" on its own arrangements for the design, but the The general principle is "bold but cautious" that is, on one hand, ERP systems should rest assured that the use of bold, use the module as possible, while at the same cautious, such as hair, for a variety of even minor differences are Do not let go, to adopt various means, including the use of analytical tools and other means, to a detailed analysis of reasons, such modest beginnings. These are the author's lessons learned, in fact, the author is located in Ronald hearing in system wide parallel connection, there have been ups and downs and valleys, but in the end he still adopted the right strategy, and achieved satisfactory results.
I where the electronics manufacturing company for small and medium enterprises, business processes, the complexity of the medium. The chosen system for its own R & D, it should be said that generally in line with business processes. But the company leadership to the system in parallel a start and not enough attention has not worked out implementation strategy, no demarcation of the period. Although the results of various departments to conduct business operations applications, but the Treasury is still the original hand-accounts continue to be used, the coexistence of two accounts, lasted almost a year. In the meantime, the system is always in "beta" state. Pairs account for the various departments co-existence have brought a lot of distress and trouble, ERP system, great advantage can not be given full play. Later, as their business increased, the amount of data increased, the leadership has finally recognized that the system Timberley discard the importance of hand accounts, so in the consolidated views of all sectors of the company worked out a 3 months throw hand account of the parallel program, companies then developed implementation strategy, as follows:
First, the first conduct an inventory to ensure that the system account, hand accounts, in-kind are consistent with, but also ensure that the system accounts and accounts in the same hand a starting point.
Second, the establishment of the daily accounts through technical means of verification procedures and mechanisms, a two-day inspection account.
Third, the daily verification, once the differences found must be promptly resolved, the issue should not be allowed to delay At the same time, corporate IT departments under the leadership of the recommendations of the 3-month parallel cycle again divided into two phases. The first stage, hand accounts of the formulas and data in accordance with the original run enterprises, at the same time ERP system operation. This stage will focus on is to examine the ERP system, processes and business process whether the big difference, ERP system, whether this is logically consistent with the needs of enterprises. The second stage, hand accounts of the Company in accordance with the original formula is still run, but the raw data using ERP systems to change the original data. This stage will focus on is to check whether the process of ERP system, a small problem, the data operation is entirely accurate. 3 months down the parallel implementation of the facts prove that the company of these implementation strategies is relatively successful. A daily verification of the first few days, I found the system quite different accounts and manual accounts, through warehouses and IT staff work overtime checking and analysis of reasons, will result in 11 to defuse the reasons for the difference, after which the system accounts and manual accounts differ gradually reduced to the last month has been basically no longer a difference, zero difference in the daily verification of both.
At present, the company where I have been getting rid of most of the manual accounts, and completely rely on the company's ERP system, the main day to day business operations, E the Company's departments, staff and management personnel, daily from the ERP system to obtain the latest data, to guide production and management, with corporate leaders as saying that "the company's ERP system has truly become a company from top to bottom are all reliable data center. " Finally, I want to say that the success of the system through the parallel phase, will make enterprise ERP system officially put into operation, thereby play an ERP system, unique features and important role in the enterprise a huge amount of information and effectiveness. Business staff at all levels will greatly reduce the workload and duplication of labor, business leadership has greatly increased the amount of information and timely feedback and strong support for enterprise management and business decisions.
The author's company, the successful conclusion of a parallel in the system, the system has been successfully on-line, the group has put the next target aimed at in the basic premise of accurate data on the start material requirements planning (MRP) of the operation. |
