At this point, you have already categorized each role in your organization into the Three Amigos. The Three Amigos are defined in a variety of ways. According to the most widely used definition, those are individuals who work in business, development, and quality/testing.
The conversation about strategy and tactics in your organization must always be centered on value. So, allow me to make the Three Amigos refer to the people who: identify value; deliver value; and measure value.
