I would go a step further and say that committees are essential to our industry. Good guidelines, codes and standards require a diverse range of inputs as well as informed and considered discussion. Committees provide the backbone of the collaborative and deliberative process where this to take place. Furthermore, the consensus building that takes places in committees is mission critical for building and maintaining trust with the public. A downside to committees from my experience is that they can easily devolve into 'talk shops' or drift due to lack of focus and absence of effective leadership, negating their ability to get things done and leading frustration and burn out. Committee success and fun in my experience comes when there is a clear and shared view of the problem being solved and what defines success, a deliberate and well-considered work process, a doable plan, and everyone pulls their own weight. Diversity of membership is also key.
