I used to work for an IT firm where I was assigned to a client that used to focus on VR for physical rehabilitation. Earlier, that company was hiring their own technology experts/consultants to provide the technology. Over the course, they chose to contract the work out. Therefore, they gave the contract to my company for the software development, maintenance and support of their products. While working in IT, I have come across that many companies are contracting lot of their work out of the company to maintain budgets and efficiency.
