How does the IT environment contribute to the success or lack of success in systems development processes?

In my personal opinion, the IT environment affects the success or failure of the systems development process in every business setting out there. For instance, a business needs to have their IT updated to a certain standard. The responsibilities of those working in IT include network administration, software development and installation, and the planning and management of an organization's technology life cycle, by which hardware and software are maintained, upgraded and replaced. If a business decides that they want to develop a new system which involves using more web-based technologies and storing more information over the cloud, the IT sector of the business and its employees are going to have to have experience or receive training in how to implement their current system of storing information into their new system they are trying to develop. A business have many other things they need to consider other than just the IT. Clearly business analytics will be involved which will help communicate the technical feasibility of the system they want to develop to the stakeholders involved.
