The term “Globalization” brought many challenges with itself in the field of software development. The challenge of accurate effort estimation in GSD is one among them. When talking about effort estimation, the discussion starts for effort estimation methods. There are a number of effort estimation methods available. Existing effort estimation methods used for co-located projects are might not enough capable to estimate effort for distributed projects. This is why; ratio of failure of GSD projects is high. It is important to calibrate existing methods or invent new with respect to GSD environment. This thesis is an attempt to explore the accuracy of effort estimation methods for distributed projects. For this purpose, the authors selected three estimation approaches: COCOMO II, SLIM and ISBSG. COCOMO II and SLIM are two well known effort estimation methods, whereas, ISBSG is used to check the trend of a project depending upon its (ISBSG’s) repository. The selection of the methods and approaches was based on their popularity and advantages over other methods/approaches. Two finished projects from two different organizations were selected and analyzed as case studies. The results indicated that effort estimation with COCOMO II deviated 15.97 % for project A and 9.71% for project B. Whereas, SLIM showed the deviation of 4.17% for project A and 10.86 % for project B. Thus, the authors concluded that both methods underestimated the effort in the studied cases. Furthermore, factors that might cause deviation are discussed and several solutions are recommended. Particularly, the authors state that existing effort estimation methods can be used for GSD projects but they need calibration by considering GSD factors to achieve accurate results. This calibration will help in process improvement of effort estimation.

No. of bitstreams: 1 Jose Raimundo Fonseca.pdf: 3208998 bytes, checksum: 1d07c2f744a920df74b235bd4e1801f5 (MD5) Previous issue date: 2003-04-14 / Several modeling approaches for the process of development in software engineering able of subsidizing decision making in the management of project are being searched. Metric of softwares, process modeling and estimation techniques have been independently considered either taking into consideration the intrinsic characteristic of softwares or their constructive process. This research proposes a complete, simple and efficient model for representing the whole process of development which, based on a set of features of the process and basic attributes of softwares, yields good estimation metrics (time and effort) of the development of the software still at the beginning of the process. The model relates constructive characteristics of the process to each type of organization, for identifying classes of homogeneous behavior based on Kohonen Neural Network. Directly, from this classification, according to the basic attributes of each software being developed, metrics may be estimated supported by Feedforward Neural Networks. A prototype is specified in Unified Model Language (UML) and implemented to estimate metrics for the development of softwares. Comparisons of the obtained results with those available in literature are presented. / Diversas representações do processo de desenvolvimento na Engenharia de softwares capazes de, eficientemente, subsidiar a tomada de decisões no gerenciamento de projetos, vêm sendo arduamente pesquisadas. Métricas de softwares, modelos de processo e técnicas de estimação têm sido propostos em grande quantidade, tanto devido a características intrínsecas dos softwares quanto a características do próprio processo construtivo. Buscando superar algumas das dificuldades de estimação de métricas relacionadas ao processo de desenvolvimento, este trabalho realiza, inicialmente, um estudo de ferramentas voltadas para tal objetivo e que estão disponíveis no mercado. Em seguida, um conjunto de descritores do processo em questão e também um conjunto de atributos básicos dos softwares será levantado. A partir de então, é proposto um modelo que represente o processo de desenvolvimento de maneira simples e eficiente. O modelo de processo do desenvolvimento na Engenharia de softwares relaciona as características desse processo construtivo a classes de entidades desenvolvedoras, tal que se possa estabelecer um comportamento homogêneo ao processo. Baseado nessa classificação, são relacionados, de maneira direta, métricas (tempo e esforço) de desenvolvimento com os atributos básicos dos softwares, definidos por Albrecht, visando a estimação de métricas. O modelo de processo é baseado no mapa de Kohonen e o estimador de métricas será auxiliado por redes neurais feed forward. Uma ferramenta de software (protótipo) é especificado em Linguagem de modelamento unificada (UML). Esta ferramenta auxiliará a produção de estimativas de tempo e de esforço de desenvolvimento de softwares. Comparações de resultados obtidos serão realizadas com os disponibilizados na literatura consultada.
