Modified timeboxing process model for proper utilization of resources

Now a day´s speed and time are the two major factors in software industry, so in this paper we propose a modified timeboxing model for proper utilization of resources and reduction of slack time. As a result a good quality software is produced in less time period. In case of modified timeboxing process model, we divide each stages of timebox of timeboxing process model to different sub-stages and execute them concurrently to reduce the slack (free) time. In the proposed model each iteration is done in a timebox of fixed duration having some specific functionality.
