Global software development (GSD) is one of modern trends in software engineering. The last years has witnessed a significant increase in the adoption of Agile in GSD .This paper considers the issue by examining whether Scrum practices used in mitigation of temporal distance-based GSD coordination challenges. We were used Cisco TelePresence tool in Synchronization communication for simulation of face to face meetings. We were designed a simple algorithm to help project managers in determining the appropriate strategies. This algorithm is based on the temporal difference between the sites. This is may be great or simple. Through temporal difference, we calculated number of working hours overlapping. Which are classified in the three cases and each case has number of strategies are sufficient to overcome this challenges.
