Bias to Action: Brellium teammates do not wait to make reversible decisions or seek unnecessary approval. We quickly decide and move forward. If the decision was incorrect, we quickly reverse it and move forward.

Thinks for themselves: Brellium teammates do not take things at face value. We ask "why" until base truth is reached. If a better solution is present, Brellium teammates use it, regardless of status quo.

Negative Maintenance: The opposite of high maintenance isn't low maintenance - it's negative maintenance. Brellium teammates are poised under pressure, self-motivated, self-improving, self-disciplined, self-aware, and non-defensive.

Expect Excellence : We hold ourselves to exceptionally high and continuously rising standards. We strive for thoughtfulness in our decision making, and for speed and quality in our execution. We acknowledge trade-offs and communicate proactively.

Communicate with Clarity : Brellium teammates communicate concisely, directly, and purposefully. We optimize for ensuring our points are easily understood the first time.
