Accurate development time estimation is crucial for project management in general, and critical for software intensive systems projects, in particular. Before beginning the project, little information is available for development details. Therefore, development time may not be estimated correctly. If data on previous projects in the same domain is available, this can be used for development time estimations. At the beginning of the project, requirements are defined and requirements specification document is created as a formal document in the organizations. By using the reused requirements from previous projects, a similarity analysis can be performed and this analysis can be used for development time estimation. This study investigates the applicability of a model that was proposed earlier for project management in general, in software intensive systems development projects. In this scope, the impact of requirements reuse on product development duration for different products in a similar domain is studied. Similarity analysis has been performed for different products in the same domain and the result of this analysis is used to estimate the development time. For development time estimation, Griffin’s model [9] is used. For the applicability of Griffin’s model for industrial companies, nine case studies from different organizations have been performed for software and system development projects which consist of hardware and software components. The results of the case studies are compared with Griffin’s model. According to the empirical results, a modification to Griffin’s formulation for product development time is proposed for software projects. For the projects which include only software or both software and hardware, the proposed model will guide project managers to estimate project budgets more accurately.

An Error prevention model for cosmic functional size measurement method Salmanoğlu, Murat; Demirörs, Onur; Department of Information Systems (2012) Estimation and measurement of the size of software is crucial for project management activities. Functional size measurement is one of the most frequently used methods to measure size of software and COSMIC is one of the popular methods for functional size measurement. Although precise size measurement is critical, the results may differ because of the errors made in the measurement process. The erroneous measurement results cause lack of confidence for the methods as well as reliability problems for effort...
A Method to decrease common problems in effort data collection in the software industry Özkaya Eren, Ayşegül; Demirörs, Onur; Department of Information Systems (2012) Efficient project planning and project management is crucial to complete the software projects in expected time and requirements. The most critical stage in project planning is estimation of the software size, time and budget. In this stage, effort data is used for benchmarking data sets, effort estimation, project monitoring and controlling. However, there are some problems related to effort data collection in the software industry. In this thesis, a pilot study and survey study are conducted to observe co...
An Automated defect detection approach for cosmic functional size measurement Yılmaz, Gökçen; Demirörs, Onur; Department of Information Systems (2012) Software size measurement provides a basis for software project management and plays an important role for its activities such as project management estimations, process benchmarking, and quality control. As size can be measured with functional size measurement (FSM) methods in the early phases of the software projects, functionality is one of the most frequently used metric. On the other hand, FSMs are being criticized by being subjective. The main aim of this thesis is increasing the accuracy of the measu...
A Software benchmarking methodology for effort estimation Nabi, Mina; Demirörs, Onur; Department of Information Systems (2012) Software project managers usually use benchmarking repositories to estimate effort, cost, and duration of the software development which will be used to appropriately plan, monitor and control the project activities. In addition, precision of benchmarking repositories is a critical factor in software effort estimation process which plays subsequently a critical role in the success of the software development project. In order to construct such a precise benchmarking data repository, it is important to have ...
A Functional software measurement approach bridging the gap between problem and solution domains Ungan, Erdir; Demirörs, Onur; Department of Information Systems (2013) There are various software size measurement methods that are used in various stages of a software project lifecycle. Although functional size measurement methods and lines of code measurements are widely practiced, none of these methods explicitly position themselves in problem or solution domain. This results in unreliable measurement results as abstraction levels of the measured artifacts vary greatly. Unreliable measurement results hinder usage of size data in effort estimation and benchmarking studies. ...
