Part of the planning process involves analyzing the impact the technology will have on your practice. Do not assume that it will have only positive effects. When you know where you want to go and how you want technology to help you get there, you can start to get specific about choosing hardware and software. You will be surprised at how easily you can now deal with the blandishments of sales people. Look for hardware and software that has been proven in law office applications, even if you have to pay a little more.
Technology can soak up enormous amounts of non-billable time.
Unless you really know what you are doing, get someone experienced to do your installation. You should develop a relationship with someone in your community who knows your set-up and can help you get going and keep running. Once you are going, you will begin to see the impact of the technology on your practice. Monitor the changes carefully. Budget time for monitoring.
