A Set of Metrics for the Effort Estimation of Mobile Apps
0 likes411 views
The document presents a systematic approach to effort estimation for mobile app development, highlighting the growing complexity and size of mobile applications and the need for specific management tools. It proposes a set of cost drivers and metrics for model-based effort estimation, validated through surveys with project managers and experts in the field. Future directions include evaluation with industrial companies to assess the usefulness of these metrics in predictive models.
