When implementing a new computer system, I recommend a method called Sample Company Implementation. This method is much more efficient than the old “Dual System” conversion methods, since you only enter actual transactions in one system at a time. It also takes all the pressure off the people involved in the conversion, since they learn the new system in a “Sample Company” where any mistake that they make will have no bad effect on anything. Once the transactions are entered you can run the various reports in the new system to see where the information shows up and to verify the accuracy of the process. During this time, you should decide which of the reports you will run on a daily, weekly and monthly basis.
In order to accomplish this, you should create two “companies” in your system. One is the “Live” company and the other is a “Sample” company. This method consists of the following steps:
- Load Master Files in Live Company
- Copy the Master Files into the Sample Company
- Enter small batches of Transactions in the Sample Company
- Check Results and make Adjustments as Necessary
- Select a “Go Live” date. Follow the Instructions in the Preparing to Go Live Guide.
- Enter or Upload the Beginning Balances and Historical Information as available.
- On “Go Live” date, Begin Entering All Transactions into the Live Company
1. Load Master Files in Live Company
Master Files consist of the Customer Master File, Vendor Master File, General Ledger Account File, etc. Most of these files can be transferred from data that is in your existing system. During the Sample Company implementation period, you do all of your actual daily work in your old system.
NOTE: Once the Master files are loaded, they must be maintained on a current basis, e.g. If you add a new Customer, Product or Vendor, etc., each of these will have to be added to your Old System (where you are doing your daily work) and to The new system Live Company. This will ensure that the transaction data, that gets entered or transferred later, matches up with the proper Customers or Vendors and Inventory Items.
2. Copy the Master Files into the Sample Company
Once the Master Files are updated in your Live Company, you should perform a procedure to copy these files into the Sample Company, so that at that moment, the data in the Live Company and the Sample Company match exactly. As you begin your Transaction Training, the data in the Sample Company becomes different than that in the Live Company, since no transaction data is entered into the Live Company during the initial training process.
NOTE: Do not enter Sample Transactions into the Live Company.
3. Enter Small Batches of Transactions Into Sample Company
During the Sample Company process, you will select certain actual Purchase Orders, Sales orders, Purchase Order Receipts, Invoices, etc. to enter into the Sample Company Database. The purpose of entering this information will be to become familiar with the procedures used in the new system.
This is also the time to establish your company specific procedures. The new systems are quite flexible and it should be able to adapt to most of your existing procedures. In many cases though, it will be to your advantage to change some of your procedures to take advantage of the enhanced technology offered by the new system.
NOTE: Do not enter Live Transactions into the Sample Company. You can periodically copy the Live Company Database over the Sample Company Database; this “wipes out” all the Master File and Transaction data that has been entered into the Sample Company. It is replaced with the Live Company Data that should include the latest additions to your Master Files.
4. Check Results and Make Adjustments as Necessary
During this time, you should print all of your business forms to be sure that the information appears on them in the layout that you require. Do not enter any more transactions than you need to enter to understand the process and have a reasonable amount of practice. Entering large quantities of transactions will be a waste of time.
During this time, you should also print the PO Receipts Journals, Invoice Journals, Scheduling and Expediting Reports, Inventory Reports, etc. so that you become familiar with where the data will be found in the new system.
5. Select a “Go Live” date.
The “Go Live” date should be the first of a month. It is often convenient if this can be a month that starts on a Monday or Tuesday. Sometimes people will “cut off’ the old month a day early in order to take care of all the odds and ends that come up during this important time.
6. Enter or Upload the Beginning Balances and Historical Information as Available
As you near the “Go Live” date you should review your Purchase Orders and your Sales Orders. Any Purchase Orders or Sales Orders that will not be Received/Shipped prior to your “Go Live” date should be entered into the new system. They don’t need to be entered into your old system. In our case, we do not transfer these from existing data, so whether or not we are converting data for your Beginning Balances and History, these will still be entered.
NOTE: Once the Open Accounts Receivable, Accounts Payable and Inventory Balances are entered, print the Aging Reports and the Inventory Report and compare them to the equivalent reports in the old system. It is very important that you get started on the right foot.
7. On “Go Live” date, Begin Entering All Transactions into the Live Company
Starting with your “Go Live” date, all information will be entered into the new system. You will not enter any more information into the old system. It is obsolete. This way you never have to do double work and you will assure a smooth transition to
The new system with a minimum of disruption of your business.
