Last week, I posed a question about which of two people would make a better member for a joint leadership team. One employee was highly knowledgeable about the organization, but was reluctant to share that information. The second was less knowledgeable, but more willing to share information and work as part of the team.
To me, the answer is clear. Effective teams require the open sharing of information by all members of the team, a commitment to work together, and a desire to be a part of solving workplace related problems. Holding back is not acceptable, no matter how knowledgeable the person might be.
My preference would be to have the second person on the team in favor of the less participative member. After all, of that person will not share their information and participate, how useful with their knowledge be?
