I hope what I\u2019m about to say is not news to most of you. Recently I had a conversation with a client that made me realize some system implementation practices from the \u201890s and even earlier live on. Among these obsolete habits are parallel live periods, converting years of detailed historical data to the new system, Jan. 2 go-lives, functional customizations, and bypassing new software releases. Once upon a time each of these was considered a best practice, or at least common practice. But in each case, what was once common is now a bad idea and usually introduces risk.<\/p>\n\n\n

Parallel live periods are a great example of things we should no longer do. If that\u2019s not a familiar term, it describes the practice of keeping an old system up and running while the new system goes live and is used in tandem with the old one. The idea was that this is the best way to make sure that the new system operates as expected and produces the same outputs or outcomes as its predecessor. The problem is, everybody who uses the system to do their job has to do duplicate work during the parallel period, usually for a month or a quarter. And sometimes people make mistakes and introduce errors.<\/p>\n

The good news is that parallel processing was replaced with a far more effective alternative. Several rounds of rigorous testing and validation, along with careful review and sign-off on the result, offers multiple benefits. First, it ensures that a new system works in individual components and from end-to-end. It also serves as a practical training tool. If there are issues with setup, configuration, integration or data conversion, the testing and validation program tends to be much better at identifying and isolating them.<\/p>\n

Avoiding a nightmare<\/h2>\n

As for the others? Converting historical data in detail is a nightmare of validation that requires the mapping of old codes to new codes and is often a huge technical challenge for the new system. Generally, systems \u201clike\u201d to have transactions input so that they can be processed and validated according to system rules. Stuffing that data in the back end is not how the new system wants to intake details.<\/p>\n

And, although it seems great to have years of detail for just-in-case reporting, in practice it\u2019s seldom used. The juice simply isn\u2019t worth the squeeze. What\u2019s done instead is keeping the old system around for reporting and research or dumping of historical information into a data mart. If you insist on converting history, focus on summarized information. Month-end account balances, for example, are much easier to convert and validate and tend to take care of most reporting and analytical needs.<\/p>\n

At first, going live on Jan. 2 might seem sensible\u2014a fresh start for the new year\u2014but for most businesses, it\u2019s the worst time for the required time-intensive activities. That\u2019s particularly true if the system in question is used for accounting. Instead, pick a month that doesn\u2019t end a quarter, and convert any necessary details from the beginning of the year through go-live. Trust me, it\u2019s far less painful.<\/p>\n

Functional customizations are, thankfully, getting harder to do. And less necessary. In their place have come a myriad of configuration options in most systems that, although they add complexity to implementations, also typically allow the new system to be configured to work the way you want it to. What\u2019s more, and I\u2019m sorry to be telling you this, you\u2019re just not that special. If you do have a great idea for a functional enhancement or whole new functionality, get the vendor to make it part of the base product.<\/p>\n

Finally, in a SaaS world, getting out of sync with the latest version is also becoming much harder. Think about your banking app\u2014your bank doesn\u2019t ask you if you\u2019d like the new version; that version simply gets pushed to you. This is a good thing. You can\u2019t sit on an old version until it is so old that you basically have to re-implement, in some cases indefinitely extending the life of the system.<\/p>\n
