The majority of currently used construction productivity management systems rely on result-based management techniques, which have difficulties in managing in uncertain environments. Massive amounts of time and resources are wasted due to conflicts between works and constraints in space, etc. Hence, we need to recognize the limitations of existing result-based management systems and suggest a productivity management index that is expected to ensure that the issues of productivity reduction are properly controlled. Work flow refers to the progression of work in a limited time and space. Schedule delay and expense waste can be controlled by managing the work flow. Measurement of work flow is evaluated using 3 indices: Continuity Index, Variation Index, and Productivity Index. Therefore, this research suggests an evaluation and measurement system for work flow that shows the productivity of construction work both directly and indirectly, and thereby aims at an improvement in project performance by using a target index.
