How do we measure outcomes?

Steve Capper reworded the question to what are the criteria for determining if the body of Christ is changing lives. The church usually spends time measuring outputs rather than outcomes. For example they measure success by regular attendance, being part of a small group, and prayer time, but measuring outcomes looks at if the life is similar to Christ's and if mentors are helping students to accelerate academically as well as emotionally and spiritually and if there is improvement in behavior.
