Using cosmic funcion points and story points together in agile frameworks, Çevik Yöntemlerde Cosmic Işlev Puani ve Hikaye Puaninin Birlikte Kullanimi

Abstract

Story Point (SP) is one of the most common metric in agile frameworks such as Scrum and Kanban. Although being subjective, story point is very useful for grooming and sizing of the backlog items, cost, squad velocity and capacity estimation. Cosmic Functional Points (CFP) is an objective metric used for estimating the functional scope of the software and it is an ISO standard (ISO 19761). This study investigates the use, similarities and differences of boh SP and CFP in agile software development practices in the largest technology and communications provider of Turkey. As a result, SP is an effective tool for grooming the user stories whereas CFP provides successful results for measuring output of the squad, quality trend and outsource contracts. Also, a preanalysis for a linear regression model of CFP versus effort estimation is conducted in this paper and the initial results are shared. © 2017 Elsevier B.V., All rights reserved.
