time span of discretion
time span of discretionthe length of time that elapses before an employee's work is checked by a supervisor. The concept was developed by the social psychologist Elliott Jacques (1917-) who believed it was a viable way of quantifying the level of judgement and discretion involved in a job. Jobs that involve little decision-making, such as assembly-line work, have a very short time span of discretion whereas managerial jobs, which have a much greater judgemental element, have a much longer span.
The time-span theory can be said to be an attempt objectively to incorporate the notions of responsibility and judgement into systems of WORK MEASUREMENT and JOB EVALUATION. Jacques has argued that it could form the basis of an equitable pay system, with rewards being based on the amount of discretion involved in each job. See JOB DESIGN AND REDESIGN.
