Abstract: An extended analytic model of sequential iterative processes is proposed. The rework impact factors included in this model take into account the impact of iteration on the task duration and the remaining time of the task at the same time. An Extended form of Design Structure Matrix(EDSM) is introduced. The EDSM can describe the model. An analytic method for calculating the expected duration of the extended sequential iterative process is presented on the condition of assuming that the model parameters are deterministic. This method is illustrated by an application involving the calculation of the expected duration of software development processes.
