requirement gathering for software development project is the most crucial stage and thus requirement engineering (RE) occupies the chief position in the software development. Countless techniques concerning the RE processes exist to make sure the requirements are coherent, compact and complete in all respects. In this way different aspects of RE are dissected and detailed upon. A comparison of RE in Agile and RE in Waterfall is expatiated and on the basis of the literature survey the overall Agile RE process is accumulated. Agile being a technique produces high quality software in relatively less time as compared to the conventional waterfall methodology. The paramount objective of this study is to take lessons from RE that Agile method may consider, if quality being the cardinal concern. The study is patterned on the survey of the previous research reported in the coexisting literature and the practices which are being pursued in the area.

The objective of this work is to apply metabolic algorithm to the various items involved during the software development processThe metabolic algorithm is introduced in the rewriting mechanism of membrane or P system considering many time varying functionsRules for requirement evolution, reaction between items in the membrane, communications between data items, process speed-up and abort rule are being proposedThe metabolic algorithm is applied for the transformation of user requirements into system requirements which can be further segregated into functional as well as non-functional requirementsThe requirement elicitation is illustrated and verified to obtain the most expected requirement objects using C# programming language.

Feature models have been widely adopted to reuse the requirements of a set of similar products in a domain. In feature models＇ construction, one basic task is to ensure the consistency of feature models, which often involves detecting and fixing of inconsistencies in feature models. While many approaches have been proposed, most of them focus on detecting inconsistencies rather than fixing inconsistencies. In this paper, we propose a novel dynamic-priority based approach to interactively fixing inconsistencies in feature models, and report an implementation of a system that not only automatically recommends a solution to fixing inconsistencies but also supports domain analysts to gradually reach the desirable solution by dynamically adjusting priorities of constraints. The key technical contribution is, as far as we are aware, the first application of the constraint hierarchy theory to feature modeling, where the degree of domain analysts＇ confidence on constraints is expressed by using priority and inconsistencies are resolved by deleting one or more lower-priority constraints. Two case studies demonstrate the usability and scalability （efficiency） of our new approach.

A new method for the development of post and telecommunication information systems (PTIS) is presented in the paper. The advantages of traditional methods such as life-cycle method, prototyping method, and object-oriented method are synthesized in the new method. By establishing a general model of PTIS, the new method makes the developing life cycle shorter, quicker and more flexible.
