A functional size measurement method for object-oriented conceptual schemas: design and evaluation issues

Abstract

Functional Size Measurement (FSM) methods are intended to measure the size of software by quantifying the functional user requirements of the software. The capability to accurately quantify the size of software in an early stage of the development lifecycle is critical to software project managers for evaluating risks, developing project estimates and having early project indicators. In this paper, we present OO-Method Function Points (OOmFP), which is a new FSM method for object-oriented systems that is based on measuring conceptual schemas. OOmFP is presented following the steps of a process model for software measurement. Using this process model, we present the design of the measurement method, its application in a case study, and the analysis of different evaluation types that can be carried out to validate the method and to verify its application and results.

Estimating the Effort of Mobile Application Development

“…The methods identified in the survey can be seen in Table 1. Pastor and his colleagues [28] 2004 Finnish Software Metrics Association FSM The Finnish Software Metrics Association (FiSMA) [29] Table 1 displays in chronological order the main estimation methods, showing the year of creation, the name of the method and the author of it. For each of the methods identified, a summary of the description and characteristics was developed, as can be seen in the following items.…”

“…Its characteristics are: the classes are considered internal logical files and concepts such as inheritance and aggregation are also relevant to the estimation [28].…”

Functional Size Measurement and Model Verification for Software Model-Driven Developments: A COSMIC-based Approach

“…Therefore, the functional size of a model will not vary even if some elementary processes have a very large number of DET, RET, or FTR [Giachetti et al 2007;Kitchenham 1997]. Even though we found approaches that measure the functional size in MDD environments in the literature [Abrahão et al 2006] , these approaches are FPAbased and also have the FPA limitations.…”

Un procedimiento de medición de tamaño funcional para especificaciones de requisitos

“…Para esto, Abrahão aplica un marco formal denominado DISTANCE [69]. OOmFP [53] incluye la medición de cuatro perspectivas: datos, proceso, comportamiento, y presentación que forman parte del método OO-Method [54]. Abrahão también valida la extensión de OOmFP para aplicaciones web, mediante la incorporación de una perspectiva navegacional que caracteriza al método de desarrollo OOWS [98].…”

“…Para medir el grado de variación entre las medidas de tamaño funcional obtenidas por los diferentes sujetos usando RmFFP, se utilizó una ecuación estadística propuesta por Kemerer [103], la cual fue utilizada exitosamente por Abrahão [53]. Esta ecuación fue calculada tomando la diferencia entre el valor del tamaño producido por un sujeto i y el valor promedio producido por los otros "n-1" sujetos de la muestra, dividida por este valor promedio.…”
