I have been pondering the idea of removing landscaping, hardscaping, and irrigation installs from my service menu and specializing in grounds management only. I have noticed my margins declining in the design/build sector due to a number of factors, but grounds care has actually gotten better for me despite rising materials costs (and I have learned to enjoy it more). Anyone who has read Jim Collins' book, Good to Great knows about what is referred to as the "hedgehog principle": find what you're best at, and focus on nothing but that. Companies who have done this (in the book) went from good to great, where those who were jacks of all trades to everyone ultimately had challenges (some failed completely). For me, I feel that positioning my company as a full service grounds management firm that specializes in nothing but grounds management could be a great move--I certainly have the education, experience, and drive to make it happen. What I don't have is the insight from others--you, my trusted colleagues here on Lawnsite. If any of you have ever made a jump like this, please post about it here.
