Abstract

Communication delay is a main obstacle in global cooperative software design and rescheduling design tasks is essential to reduce such a impact. The duration of task and communication delay is undetermined in global software design, and the task sequence is not determined when rework is required to fix the possible defects in the progress. Therefore, it is hard to distinguish when and which task should be handled and the design task rescheduling can be difficult to accomplish. Dynamic Micro-estimation refines the estimation of effort and duration for the tasks in the next short period. Based on Multiple Component Status Transition Graph (MCSTG) and Micro-estimation, the probability of a task should be handled and the available time for this task to be finished can be easily estimated. The Micro-estimation extended MCSTG enables the project managers to reschedule the tasks according to their criticality and importance so as to facilitate the collaboration in global software design.
