““Evaluation must be done in hindsight, after the work has been done, not for proposals for work to be done. That said, secondary factors must carry some weigh, because research results depend too much on historical contingency and luck. As articulated by Ralph Bown, vice president of research at Bell Labs from 1951 to 1955: 'A conviction on the part of employees that meritorious performance will be honestly appraised and adequately rewarded is a necessary ingredient of their loyalty. This appraisal, to be fair and convincing, must be based on the individual's performance and capabilities rather than wholly on the direct value of his results. A system which rewards only those lucky enough to strike an idea which pays off handsomely will not have the cooperative teamwork needed for vitality of the enterprise as a whole.””
