If you're thinking about deploying
Panorama Consulting Solutions recently released their 2014 ERP report. The report is based on a survey of 192 representatives of variously-sized organizations who have worked on ERP initiatives in the past year. A majority of respondents (70%) reported being satisfied with their ERP software, but the survey also showed some ERP implementation pains. 54% of ERP projects went over budget, 72% took longer to implement than planned, and 66% report receiving less than 50% of the measurable benefits they had expected from their ERP solutions. But the report also shows that the majority of respondents paid relatively little attention to organizational change and business process management as part of their implementation, which may explain the pains.
If you upgrade from a screwdriver to an electric drill, would you use the drill in exactly the way you used the screwdriver? No, that would be silly. Similarly, if you deploy Microsoft Dynamics SL to become more efficient, you're unlikely to maximize the value of your new solution without also improving your business processes to match your new shiny tools.
Business process analysis and Microsoft Dynamics SL deployment should go hand in hand. It decreases the risk of implementation pains and gives you a more accurate view of the tangible benefits you can expect from deployment.
