The management of a software project is a complex and lengthy process which includes activities like managing project requirements, managing the scope of work, composition and team management, cost management, etc. targeting the final result of the project, what will be given to stakeholders / clients to be expected, and always in accordance with the documented project requirements. The purpose of this thesis is the study of "Software Project Management" and the study of factors affecting this process. More specifically, this work focused on the study of factors affecting the complexity of a software project, such as the factors of time, cost, risk, and test metrics, used for recording and assessment of these factors in order to improve this process management and ultimately yield a better outcome to stakeholders. Complexity refers to the search for and identify factors toward a successful prediction of adverse complications of a work. Measuring the complexity of a software project leading to conclusions directly and indirectly for implementation of project activities, as well as what are the parameters that can lead to failure, low productivity or unsatisfactory outcome. To measure the complexity of software developed web application, which enables the researcher to seek metrics appropriate for the work you want to evaluate, to combine with the

To develop software was used software development methodology Joomla, language UML, the content management system Joomla, and the data stored in relational database MySQL. Key Words: project management, metrics, complexity, methology, software, proceedings, CMS Content: Text, ICONIX methology, database and analysis of database using MySql, appendix describing website's pages using php language.

Project Management is the application of knowledge, skills, tools and techniques to project activities to meet the project requirements. Organisations have the need to analyse methods, processes and also to use the best practices in order to provide best products to their stakeholders. A project appears to be unique and temporary. This is because when an organisation is starting a project, it has to define project's duration and its characteristics. Each project has to satisfy its goals which may be the market demand, the needs of new software of the Software Project Management defers from the traditional Project Management, because in software project management the organisation have to organise, analyse and provide to their stakeholders a useful product, that satisfy their needs. In software project management the organisation the software products are easy to change or update. In this paper we are trying to describe methods and practices, based on Project Management Body of Knowledge (PMBOK). PMBOK includes the following fine (5) groups which are initiating, planning, executing, monitoring and controlling and closing. In order to describe better the above groups PMBOK has the following knowledge areas which are Integration Management, Scope Management, Time Management, Human Resource Management, Communications Management, Risk Management, Procurement Management. These nine knowledge areas describe whole project, each scope and the goals it has to achieve, in order to satisfy the stakeholders. We have to mention that these areas are not the same for all the projects have been created. As we said before each project has the characteristic that is unique. Because we have to analyse large projects, a way for better organise is to make categories, in which we insert metrics. A metric determine the used strategy of the project and also is used for checking the processes of it. The categories and the metrics lead us to prescribe the complexity of software project management. Complexity can provide us useful information about the development of the project. For example can appoint the risks the project has, the cost or the amount of human resources the organisation will need for the sustainable development of the project. Furthermore, in order to measure complexity of a project, this paper describes the development of a tool, which the main goal is to calculate models, which are in a project, based on metrics using evaluation scales. At first a description of the application is described with the ICONIX methology, then the database and in the end using appendixes all php code from the website tool.
