Estimateurs de la taille d'un logiciel à partir des spécifications de conception

Cette étude présente des modèles d'estimation de la taille d'un logiciel mesurée en nombre de lignes de code. L'originalité de l'étude provient du fait que les métriques utilisées pour prédire le nombre de lignes de code sont disponibles durant la phase de conception d'un logiciel. Les modèles sont mis au point de façon empirique en procédant à l'analyse de quatre échantillons de mesures provenant de logiciels conçus à l'aide d'organigrammes structurels ainsi que d'un échantillon de mesures provenant d'un logiciel conçu à l'aide de diagrammes d'enchaînement d'écrans. Les modèles sont évalués à l'aide de six critères. Dans un cas, l'évaluation du modèle permet de conclure à une applicabilité immédiate

A Method For Measuring The Functional Size Of Embedded Software

Software has become a key component of most automated process control devices. It offers a high degree of flexibility in adjusting the behavior of those devices. Proper management of the development and maintenance of process control software is therefore a key issue be it for reasons related to internal organization performance or for benchmarking against the best in the industry. Measurs ar

Developing Project Duration Models in Software Engineering

This paper uses published indicators of IT development projects performance, including recent projects, as the basis for an analysis of the relationship between two key aspects: project's effort and duration. The analysis results in mathematical models of that relationship which may be used as a guide for project duration planning and forecasting. The models are based on the analysis of empirical data contained in the 1997 release of the International Software Benchmarking Standards Group (ISBSG) repository

A Data Collection Framework For It Governance

IT projects continue to be canceled, delivered late and over budget, fail to deliver what was expected or deliver error-prone results. This state of affairs prevails today despite more than 30 years of evolution in the methods, techniques and tools of information technology, software engineering and project management. It is clear that software professionals and organizations have not adequately harnessed the bodies of knowledge required to avoid these project delivery pitfalls

Measuring the Functional Size of Real-Time Software

Function Point Analysis (FPA) is a technique designed to measure the functional size of software products. The technique measures product size from the user's point of view rather than from a technical perspective. FPA is now widely used in the MIS domain, where it has become the "de facto" standard. However, FPA has not enjoyed the same degree of acceptance in other domains, such as real-time software. This paper reports on work carried out to adapt FPA to the specific functional characteristics of real-time software. The extension proposed, called Full Function Points (FFP), is described and the results of field tests are discussed
