The first step is to find multi-talented people in whom you can trust. Of course you want to know that they have the skill, knowledge, and ability to do the job. In addition, you want to make sure that those you chose share the same set of values and are philosophically aligned with your strategy. Look for people who have track records working with other people, not just with clients. Client relationships are very different than team relationships.
Many people are great with clients, but less effective when working with other people.
Think of team building like planning a great party. Invite people with diverse and complementary skills, otherwise everyone will agree on everything and that is not constructive. Once your team is formed, there is a great deal of preparation before you turn over the reins of your business. Establish a clear, long-term direction. In terms of your vision, mission, goals, and objectives, clearly communicate these concepts to your team.
