The document discusses contribution accounting, which involves team members evaluating each other's contributions to a project. It provides an example where Carmen, Daniel, and Peter each received different percentages of shares based on peer evaluations. It then analyzes the results, finding that evaluations were fairly accurate with less than 10-15% difference on average. It also notes that frequent evaluations over time can lead to more accurate accounting of contributions as reputations are established.
