Software engineering is continuously gaining success day by day. In last decades a lot of growth has been observed in the software industry. Various new software development methodologies are introduced such as agile software development with increasing demand of software industry. In all these development methodologies, user requirements play an important role for completion of the successful project. If requirements are not clear it can be the reason of project failure. Now a day's some industries are not aware about the right way to collect and fulfill the requirements. This survey based study focused on the analysis of user requirements gathering practices in agile and non-agile software development teams. Main purpose of this study is to analyze the factors involved in requirements gathering practices and rate of maximum agility in tri-city (Mohali, Chandigarh and Panchkula) on the basis of different work experiences.

While software metrics typically help to assess the status of a project, product and process the suitable metrics in Agile Software Development (ASD) process is frequently questioned due to overheads involved. The software provides processes for measuring and predicting the developed quantitative planning software. In this paper there are some metrics which could be beneficial to the ASD process.

CBIR systems mainly concentrates on reusability and development of software modules. This leads to less cost and enhancement of software module. Reusability is one of the factor that leads to good development of software. Software reusability is gaining interest because it leads to time reduction in software development too. So, reusability of variables has been adopted. Various methods has been developed for this, but in proposed work, the problem of component reusability is solved using neural network in addition to genetic algorithm, in which neural network will help out for retrieval of reused components.
