Once you have designed and procured a new system, it is time to implement. A set of steps similar to the original base establishment begins. Any new equipment that is needed will be put into place; employees will be trained on the new business processes and software; the helpdesk will begin building up a knowledgebase on the new systems and applications. Because you established a solid base to work with during your initial implementation phase, you wont have to worry about breaking the business processes you have in place already.
When you started on your journey to outsourcing, you had expectations that you would never have to worry about your technology infrastructure again. Now that it is real, you will find that for the most part those expectations have been met. You now think/worry more about how you can use the application of the technology to provide your business with competitive advantage. You worry more about whether your business processes are the most efficient, and how they can take on more growth.
These are the things that you should worry about. Leave the technology worries to those who are experts in technology. Your worries should be about how to grow your business and use the technology to enable and enhance that growth.
