In order to have the software development process executing in an organized way, we must provide mechanisms to control concurrent access over the project artifacts. These mechanisms are implemented by concurrency control policies in version control systems, which may allow (optimistic policy) or inhibit (pessimistic policy) parallel development. This work presents the Orion approach, which analyzes the project historical changes and selects the most appropriate concurrency control policy for each software element. In addition, it identifies critical elements, which are candidates to refactoring. This selection aims at minimizing conflict situations, and thus improving the development team productivity. A prototype was built to enable the application of the proposed approach and two experimental studies were performed as a preliminary evaluation. 606 $aComputer software$vCongresses 606 $aSoftware engineering$vCongresses 615 0$aComputer software 615 0$aSoftware engineering 676 $a005.1015113 702 $aIEEE Staff 801 0$bPQKB 906 $aPROCEEDING 912 $a9910138934803321 996 $a2009 XXIII Brazilian Symposium on Software Engineering$92539132 997 $aUNINA
