The most common hiring mistake is judging a candidate in isolation, on their own resume, against no particular team. The Addition Read refuses to do that. It shows both sides at once: what the person does to the team, and what the team does to the person.
The setup
A go-to-market team is scaling and moving upmarket. It is already strong on Drive, plenty of push, and on Rigor, disciplined operators. But as it has grown it has thinned out on Cohesion, the connective work of holding a widening group together, and that is exactly the dimension the next phase of the mission demands most. The team read shows it plainly: Cohesion is a Single cover, carried by one person, while Drive and Rigor both sit in Overlap. The leader has two finalists.
Avery
Avery is the resume standout. Relentless Drive, exacting Rigor, the kind of operator who dominates an interview. On paper, the stronger candidate. But run the Addition Read and Avery lands right on top of the strengths the team already has in surplus. Drive deepens from Overlap to a heavier Overlap. Rigor does the same. The Cohesion gap does not move. And the two-sided view shows the mission would push Avery into strain, because the work the team actually needs is the group-holding work that runs against Avery’s grain. A great hire, and the wrong fit.
Reyes
Reyes is the quieter resume. Solid, not flashy. But Reyes is strong exactly where the team is thin, high Cohesion, with the Range to flex as the team grows. Run the Addition Read and the Cohesion single cover becomes Covered. The fragile dimension finally has a real second carrier. Adaptation Load drops, because people stop straining to cover a gap that was never theirs to hold. The two-sided view shows Reyes in a healthy stretch, used well, not overstretched.
The reveal
Avery looks better in isolation. Reyes is the right addition. You only see that when you read the candidate against the team and the mission instead of against a job description. Same strength on paper. Opposite effect on the team. That is the Addition Read.
