Research on Constraint-based Time Management Theory

To overcome the deficiencies of activity-based costing (ABC) and theory of constraints (TOC) and use the complementary characteristics of these two theories, constraints-based time management (CBTM) is proposed. In the aspect of decision-making, CBTM combines the advantages of ABC and TOC, through analyzing the relationship among time, cost and cash income over a given period to make decisions. In the aspect of continuous improvement, CBTM bases on the TOC and combines the activity analysis technique of ABC to confirm and classify constraints. Continuous improvement can be a-chieved through a set of steps:to unstable constraint, actions should be taken to elevate and transfer the constraint as soon as possible; to stable constraint, one should elevate the constraint and at the same time subordinate everything else to the constraint.
