I believe its impossible to fully characterize a person's command philosophy in a single document. An understanding of another's philosophy comes from extensive experience and interaction. Having a small number of easy-to-remember guiding principles is a useful tool to have toward attaining such an understanding. The command of a United States Navy Unit depends on the concept of sustainability. That is, the Commanding Officer (or "Officer in Charge") must always consider who will replace him/her. With the future on the mind, the present becomes a chance to innovate, a time to learn, the basis for continued capability toward whatever mission or requirements assigned, and of course a time to perform.
To make and maintain a sustainable unit, I have identified a core principles to use on a regular basis.
The one constant in the world is change. Any solution that does not consider future issues is not even worth writing down. One must adapt to change, manage change, and become better from it. Adaptable also applies to new avenues of improvement. Maintaining a process because "we have always done it this way" is not a good enough reason. "Local" maximums are not enough and some times you need to take a step back so you can take two steps forward. In general, the most common manifestation of this principle is the adoption of technology. Concrete examples include configuring your email to filter and label emails, utilizing a chat app to communicate as a group, and writing your command philosophy on GitHub. Adapting to the "now" and preparing for the "future" leads to sustainability.
Treat subordinates consistently and apply standards consistently. This make it easier for others to approach and communicate with you, but it also allows for a greater understanding of what is "good" and "bad" in your interactions, communication, and processes. To use a math metaphor, an elementary student can solve x + 3 = 5, while 3x + 5y - z = 12 would prove difficult for most adults. Consistency reduces variables and allows for better solutions with less time and effort. Whether you are developing a relationship with the members of your unit or looking for a technical solution to a mission-related problem, taking a consistent approach will improve your chances of success. Consistent interactions and processes lead to sustainability.
Transparent interaction can lead to trust and trust is essential to unit cohesion. I believe that trust comes from mutual respect and developed by consistent interactions over a period of time. To respect a person is to explicitly communicate his/her capabilities assessed under a consistently applied standard. Beyond involving every member of the team toward mission accomplishment, transparent interactions will help foster a positive command environment by setting clear goals with overt paths to accomplishment. More than an "open door policy", being transparent involves being honest, overt, and inclusive.
