IT practitioners realize that poor scheduling can cause project failure. This is because schedule overruns may be caused by the effort involved in making requirement changes. A software process improvement challenge is to better estimate the cost and effort of requirements changes. Difficulties with such effort estimation is partially caused by lack of data for analysis supported with little information about the data types involved in the requirements changes. This research is an exploratory study, based on change request forms, in requirements change categorization. This categorization can be used to develop an empirical model for requirements change effort as input into a cost estimation model. An empirically based estimation model will provide IT practitioners with a basis for better estimation of effort needed for requirements changes.
