1. Leaders hold tight to the vision: I was recently working on a committee for a non-profit where we were planning an event. We had a lot of heated discussion about the tone and look of the event. Should it be edgy? Should it be solicitous? Who are the stakeholders that we need to reach out to? We needed a leader to iron out the vision and mission. Without that person taking on the leadership role, it would have been impossible to work on the other aspects of the event.
2. Leaders ask the important questions: When we get caught up in our routines while working on a project, we don’t usually take the time to come up for air. That means we need our leader to step back periodically and ask: “How are things going?”; “What is missing?”; “What isn’t working and why?” These essential questions asked at the right times can oftentimes mean the difference between a successful or unsuccessful outcome.
3. Leaders act as liaisons: Our teams do not function in a vacuum as we are usually connected to a larger organization. It is the leader’s responsibility to make sure to keep everyone updated on the progress and the obstacles. If a team doesn’t have a leader and clarification is needed, the team might not get the best information. Leadership can provide that connecting piece.
4. Leaders energize a team to meet deadlines: The truth is that sometimes teams lose steam, unable to motivate themselves to complete a project in the necessary timeframe. Teams need a leader to not only keep track of the completion date, but to cheer them on. It can take a creative activity such as bringing in music or a masseuse to encourage team members and show them they are valued. By rolling up their sleeves and pitching in, leaders model a can-do attitude that can be contagious.
I say no because when you place someone in a power position, they tend to corrupt, take too much control, and sometimes do all the work themselves. They sometimes even start to yell, or take credit with stuff they never touched. Leaders sometimes never try to help, and I think that if you want to be a leader, do so by getting your hands dirty, don't just sit back and command, and be an example that way.
Terrible leaders lead many successful organization, and leaderless organizations are also successful. In many cases even a great leader will not be successful. Success has many components that leaders can only slightly influence. There are many examples with sports coaches. Coaches that had success with one team could not save another.
Your argument doesn't take into account bad/uninterested leaders.
Your points assume every leader is good at what they do, or even interested in running their business. A bad Leader can just as easily cause an organization to fail as a good one can make an organization succeed.
Its two sides of a coin regardless of how an Organization performs good or bad the leader takes full responsibility for either out come
