The purpose of the current study is to examine the impact of requirement changes of ongoing projects on organization procedures with respect to its performance. Instrument for this research is developed by using Nomo logic network to collect data, while content and face validity technique is used to validate the instrument. Similarly multiple regression technique is applied to analyze the data. From results it is found that requirement changes significantly predicted changes in technical SOP’s (Standard operative procedures), while technology culture has a significant mediating role between requirement changes and changes in technical SOP’s. Current research is designed to uncover the challenges faced by IT organizations due to changes in requirements of ongoing project SOP’s. This study has significant importance for IT industry; meanwhile current study also addresses the critical issues faced by software development organization in ongoing projects. Through this empirical study researcher infer that requirements should be collected in complete and precise manner before execution. If there are some changes in the middle of the project then those changes should be addressed through proper mechanism and procedure.
