Try New Things
Don't be afraid to try new things.
Your consulting firm should be aware of the latest technologies and should know which technologies are best suited for a given project. This is something you will want to take advantage of. While you are the ultimate decision maker on your projects, consider a consulting company's technical suggestions for a competitive edge. They could make your project that much more successful in the end and set your company apart from its competitors.
Also, consider switching some of the roles of your company's team and the consultancy firm between projects and technologies. They are highly knowledgeable and skilled across a variety of technical areas, so switching up the work will provide the opportunity to solve different problems and take a fresh look at the tasks, especially if it's a long-term project.
