"Lead - Follow - Or Get Out of the Way" was one of the first management edicts that I learned, and I didn't learn it in business school, I learned it while guiding kayak trips as a UCLA Outdoor Adventure Guide. On the water, there is the constant realization that anything and everything can happen, and we are constantly in problem solving mode. For instance, while kayaking in the San Francisco Bay, suddenly the winds went from a light breeze to 30mph and an entire line of kayaks was flipped over under the Golden Gate Bridge in the swirling waves. With near zero visibility and with huge ships bearing down on what must have looked like a spattering of yellow, blue and red M&Ms, we quickly needed to get all of our paddlers out of harms way. One person took control of rescuing the paddlers who were in the water, others supported him, and the rest who were still in their boats got the heck out of the way. On the water, there can only be one leader making decisions and everyone else supporting that experienced person. Common sense, right?

So why is it in business situations, it should be any different? In any situation clarity will usually provide greater and faster results than confusion. And whether it is ownership of an area, ownership of a project or ownership of solving an issue, clear roles are available and necessary and work can be distributed accordingly. The Lead, Follow or Get Out of the Way model provides this clarity. But there is one remaining question: what do you do with senior folks who have been there before? Are they also leaders? Are they followers? Or does the model require the addition of the Advise role? Let's start by defining what these roles are intended to do and why they should be defined/assigned in advance:

1) Lead: The person responsible. One throat to choke. The person who has 100% decision making authority regardless of how many voices are involved. Sometimes this person is referred to as the "Design Authority" as they are the person who owns the vision and the is the architect of the approach or experience.

2) Follow: Get the work done. Do what needs to be done. Follows through on what the "Leader" asks to be done. This is the simplest of roles but arguably the most important. This person is not an "Order Taker", meaning they have a voice, but push comes to shove, their primary responsibility is getting the work done, not debating with the Leader.

3) Advise: Typically another experienced SME or leader who ensures that they are NOT confused by the team with the "Leader" but they make themselves available to the "Leader" should that person ask for or need their support or advice. They can be applied with a light touch, or they can act as a backstop to ensure that the leader doesn't inadvertently step onto a landmine. That is largely dependent upon the experience of the leader, the maturity of the advisor and the culture of the organization.

4) Get out of the way: If you can't contribute, step aside. Even well intended efforts to clear any obstacles out of the way of the "Leader" or the team can be viewed as interference and create confusion for the team. The key, like most everything, is to proactively communicate, ask the leader if you doing this will help. If they reject your offer, it's typically better just to step aside as they may have a strategy that you aren't fully aware of. And in no circumstances should you go down a separate path and start giving out instructions to team members who should be following the Leader. Without clarity, this person can be seen as another leader who the team might look to for guidance but an experienced and mature person in this role recognizes that doing so will only dilute the authority of the Leader, so they step aside. (Sometimes, they also may be asked to become an "Advisor")

When these roles are clearly defined and assigned, assuming you have qualified people, the result will typically be achieved faster, more effectively and with a lot less stress or conflicts. This model assumes that there is more than one right way to solve a problem, but that the "Leader" is 100% empowered to pursue the solution as s/he chooses. Everyone else is there to support or clear out of the way.

So why the Advise role? Largely this role is here because smart managers can't help themselves. We all believe that we have the "right" way of approaching the issue, and only if we can convince the leader of this approach, everything will work out swimmingly. We can get it done faster and more effectively than the person in charge. In reality, we all know there are two problems with this mindset. The first is that if we always are in charge, we'll never develop the leaders behind us. The second is that even in life and death medical situations, there are usually 4 or 5 ways to approach a patient condition; four will largely end in a similar and healthy result, one will likely kill the patient. One of the toughest things for intelligent and Type-A professionals to accept is that as long as the leader doesn't choose the one fatal choice, any of the other choices are acceptable. So largely the Advise role is to ensure the Leader doesn't choose that one path, not to push them toward any one of the remaining four.

So what do we do with the Type-A manager who is chomping at the bit with that one "right" approach? Clearly defining and assigning them to an Advise role allows the well intended and experienced SME or manager to know that their voice will be heard. This simple act will largely prevent the distraction, disruption and potential dissension that can occur when that well intended manager feels that they must be heard and the only way to do that is to force themselves upon the situation.

So why wouldn't these roles be defined in every situation and in every organization? There are two main reasons, first because they are taken for granted, and second because the culture created in the organization is trying to promote collaboration, a flatter decision making culture where everyone has a voice. Unfortunately, when these roles are not clearly defined, or multiple people feel they have an equal role in the decision, it may seem like we are empowering greater collaboration and greater empowerment, but in reality this only occurs in the smallest minority of situations. What typically occurs is that two or more people debate the approach or solution and they all feel they have the right to question each others decisions. This makes the people who need to do the work very confused and sends them running around in multiple directions doing the same work multiple times in different ways. This model can be very frustrating for everyone involved because nobody feels empowered to do anything and it seems that management has a lack of trust for everyone and assigns the same task to everyone. The results are success only through heroic efforts and great talent doesn't stick around to live through this experience again.

Usually management didn't create this situation intentionally, Management may have told the problem to everyone but they assume that the team will quickly have a discussion on how the problem will be approached. They assume the team will assign people to the necessary roles. In some circumstances the organization does do this on purpose, they want an organization where everyone is compelled to fight be the loudest and most visible leader in order to advance. This article is not about addressing that type of an organization. Addressing that would require a couch and many hours of therapy.

But if your otherwise healthy organization assumes that you should be creating these roles without them having to tell you, take a pause and see what you can do to improve your ability. The next time you work on a problem, project or area, think about whether you have created clarity or confusion with how your team is organized for success. And absent any instructions, make your own decision of where you can help most and communicate it to your teammates:

In this tutorial we consider single-leader-multi-follower games in which the models of the lower-level players have polyhedral feasible sets and convex objective functions. This situation allows for classic KKT reformulations of the separate lower-level problems, which lead to challenging single-level reformulations of MPCC type. The main contribution of this tutorial is to present a ready-to-use reformulation of this MPCC using SOS1 conditions. These conditions are readily available in all modern MILP solvers that then solve the single-leader-multi-follower problem to optimality. After formally stating the problem class under consideration as well as deriving its reformulations, we present explicit Python code that shows how these techniques can be realized using the MILP solver Gurobi. Finally, we also show the effect of the SOS1-based reformulation using the real-world example of industrial eco-park modeling.

A maze-solving algorithm is an automated method for solving a maze. The random mouse, wall follower, Pledge, and Trmaux's algorithms are designed to be used inside the maze by a traveler with no prior knowledge of the maze, whereas the dead-end filling and shortest path algorithms are designed to be used by a person or computer program that can see the whole maze at once.

Mazes containing no loops are known as "simply connected", or "perfect" mazes, and are equivalent to a tree in graph theory. Maze-solving algorithms are closely related to graph theory. Intuitively, if one pulled and stretched out the paths in the maze in the proper way, the result could be made to resemble a tree.[1]

This simple method can be implemented by a very unintelligent robot or perhaps a mouse, because it does not require any memory. The robot proceeds following the current passage until a junction is reached, and then makes a random decision about the next direction to follow. Although such a method would always eventually find the right solution, the algorithm can be very slow.[2]
