A method of computing effort requirements of porting issues in source code includes estimating the minimal number of code text characters needed to be read by a user when the user is searching for porting issues, estimating the minimal number of context switches needed to be made by the user when shifting from one reading region to another reading region during the searching for the porting issues, and estimating the minimal number of keystrokes needed to be made by the user during searching for the porting issues. In a similar manner, the method involves estimating the minimal number of code text characters, the minimal number of context switches, and the minimal number of keystrokes needed to be made by the user for found porting issues. With this information the method establishes an effort model based on a weighted sum of the minimal number of code text characters, the minimal number of context switches, and the minimal number of keystrokes, for individual porting issues. The weights in the model are identified by porting issue type and user capabilities in handling each porting issue.
