Talented people are hard to find and they are even more difficult to retain long term. They have options and they know it. Having this in mind, it is important to invest in people ahead of anything else. Get the best folks you can and focus on quality over quantity. Once a team is built, then shift your focus towards processes, policies, technology, operations and partnerships.
While we all have talents, my statements are made with respect to challenges of finding individuals whose knowledge, education and passion perfectly align with the mission, vision, strategy and functional needs of your company, business or organization as that is a difficult match to find. However, once you find it, do all you can to retain it for as long as possible.
