Today, the need for information technologies is constantly increasing in order to take advantage of utilizing data. Information and Information Technology (IT) sometimes constitute bottlenecks for large-scale size enterprises in the intuitional dimension. Given the fact that the causes of these bottlenecks are usually grounded upon various reasons, the main reason is that not to get sufficient efficiency from the projects. In this study, software applications development processes in large-scale enterprises within the scope of the producing services (demand request, content preparation, preparation for analysis, software implementation, testing, user acceptance and reasons of constraints & bottlenecks) are examined, so that a research is done by dealing with how experiencing bottlenecks in this process affects project performance, information, information technology and project management concepts and life cycle of software projects in scope of project management. By determining failure rate of projects are still at a high level according to the literature survey and practice, in information technology (IT) projects, in particular with software application development projects, the failure rate of projects is determined to be above average. Furthermore, by working on simple linear model to measure the success of the project, among the IT workers in a large state-owned bank, a questionnaire is applied, which uses success algorithm in this model including the variables such as Feasibility (demand), Analysis, Design, Coding, Testing, Implementation and Delivery. By evaluating the results of this survey, the reasons that effects project performance are analyzed, bottleneck reasons of these factors and at which rate these factors influence the completion of the project for ever single factor are tried to be explained. In the application, by using correlation among factor tests, factor analysis and regression, determination of loads of the factors and validity of the model was investigated.

Gnmzde bilgiden yararlanmak iin gereken bilgi teknolojilerine olan ihtiya srekli artmaktadr Bilgi ve Biliim Teknolojisi (BT) kullanm kurumsal boyutta byk lekli iletmelerde zaman zaman darboazlar oluturmaktadr. Bu darboazlarn sebebi eitli nedenlere dayandrlmakla birlikte, asl sebebi projelerden yeteri kadar verimin alnamamasdr. Bu almada, byk lekli iletmelerde hizmet retimi kapsamna giren yazlm uygulamas gelitirme sreleri (Talep iletimi, kapsam hazrl, analize hazrlk, yazlm gerekletirme, test, kullanc kabul ve kst ve darboaz nedenleri) incelenerek, bu srelerde yaanan darboazlarn proje baarmn nasl etkiledii, bilgi, bilgi teknolojisi ve proje ynetim kavramlar ve proje ynetimi zelinde yazlm projelerinin yaam dngs ele alnarak aratrma yaplmtr. Yaplan literatr taramalar ve uygulamalara gre projelerde baarszlk orannn hala yksek seviyelerde olduu tespit edilerek, Biliim Teknolojisi (BT) projelerinde ve zellikle yazlm uygulamalar gelitirme projelerinde baarszlk orannn ortalamann stnde olduu belirlenmitir. Ayrca, proje baarsn lmek iin basit dorusal bir model zerinde allarak, bu modelde yer alan baar algoritmasnda kullanlan Fizibilite (talep), Analiz, Tasarm, Kodlama, Test, Gerekletirme ve Teslim deikenlerini ieren bir anket byk bir kamu bankasnda BT alannda alanlara uygulanmtr. Bu anket uygulamas sonular deerlendirilerek, proje baarmn etkileyen sebepler analiz edilmi ve bu faktrlerin darboaz nedenleri ve hangi oranda projenin tamamlanmasna etki ettii faktr baznda ele alnarak aklanmaya allmtr. Uygulamada iliki testlerinden korelasyon, faktr analizi ve regresyon kullanlarak faktr yklerinin belirlenmesi ve modelin geerlilii aratrlmtr.
