INTRODUCTION:

In the field of software engineering, requirements are the needs of the user that must be correctly managed and specified. In this paper we have presented the different requirements tools that can be used and well managed as per the requirements specified. A comparative study has been made to determine the top management tool that fulfills user needs.

LITERATURE SURVEY:

“Automating Requirements Management” compared the tools like DOORS, RTM workshop, caliber-RM, and Requisitepro and the features they have in common are they parse a source document to load requirements into database, define different attributes for different types of requirements, define traceability relationships, usability options and includes threaded discussions and tool learning aids^[1].

According to author Muhammad Said, “An Evaluation of Requirements Management and Traceability Tools” evaluated eleven requirements management and requirements traceability tools. The analysis summarize that requirements tools are used more instead of traceability tools. And they concluded that DOORS tool has most specifications features among the tools compared^[2].Another one said that “Selecting Appropriate Requirements Management Tool for Developing Secure Enterprises Software”, compared cradle, caliber-RM, analyst pro, CORE analyzed that caliber RM tool comes out in front with tying between cradle and analyst pro^[3].

Matthias Heindl, Franz Reinisch, Stefan Biffl, Alex Egyed,” Value-Based Selection of Requirements Engineering Tool Support”, reported on a value-based requirements tool selection approach developed at PSE that helps to find the optimal tool support and evaluated how existing requirement tools meet the needs for requirements tool support^[8].Aurora Vizcaino, in their article “Requirements engineering tools: Capabilities, survey and assessment”, states that some enhancements to be made in order to make tool support some features that are located in requirements modeling, management

and some other capabilities. They also analyzed that modeling score lower than management and other capabilities. The theory that Re tools are more oriented towards natural language than towards modeling like UML etc. Also, the lack of open data model has been detected^[5].

Tony Cant, Jim McCarthy and Robyn Stanley,” Tools for Requirements Management: a Comparison of Telelogic DOORS and the HIVE”, stated the integration of DOOR and Hive. Document production, data views, requirements and modeling, extendability are compared. Hive adds real value to front end and DOORS tool has been used to effect for this requirements listing and tracking. The comparison highlighted the innovative advantage of hive makes this an essential tool^[7].

Rajat R. Sud and James D. Arthur define “Requirements Management Tools A Qualitative Assessment” presented a comparative study of requirements tools like rational suite analyst studio, RDT3.0, teleogic doors, caliber RM based on the features and capabilities^[4]. Juan M. Carrillo de Gea, Joaquín Nicolás, José L. Fernández Alemán, Ambrosio Toval, Christ of Ebert, Aurora Vizcaíno” Requirements engineering tools: Capabilities, survey and assessment” in their article conducted a survey to gain an insight into how current RE tools support the RE process by means of concrete capabilities, and to what degree. The RE process seems to be well covered by current RE tools, but there is still a certain margin for amelioration, principally with regard to requirements modelling, open data model and data integration features^[9].

According to TSSR,A Proposed Tool for Secure Software Requirement Management” evaluvated the requirements using a tool called Tool for secure software environment risk analysis, system requirements, security of the system and project, users/group restriction, encrypted database, and traceability. There are variety of tools available but for secure software development only a few tools are helpful^[10]. Another literature Anthony Finkelstein & Wolfgang Emmerich, conveyed “The Future of Requirements Management Tools”, prospects different tools and distinguish developments that are in short term, medium term and future as well. Convergence of tools, robustness, tool integration are identifies as short term, web integration and multimedia in medium term, workflow, modeling and corporate management have been identified in long term. They state that requirements tools are the heart of the system engineering^[6].Matthias Hoffmann, Nikolaus Kühn, Margot Bittner, “Requirements for Requirements Management Tools “ ,contributed the users to compare and select requirements management tools as well as helping tool providers to direct future tool developments. It also covers the core functions such as information model, baselining, and tracebility and so on^[11].Many Browning, J. and Adams, R. (2014) Doorstop: Text Based Requirements Management Using Version Control. Journal of Software Engineering and Applications, in this journal provided an alternative to traditional requirements management called Doorstop was created as a tool to allow requirements to be stored as text files in version control^[12].

EXISTING SYSTEM.

The existing systems have compared the requirements engineering tools like DOORS, RequisitePro, and Caliber-RM, RTM workshop, cradle and concluded that requirements modeling tools are less used than requirements management tools. The tools considered are almost the same in all papers.

The different features are analyzed for these tools. The essential RE tool has to be selected based on the requirements of the user is the conclusion that papers have given.

PROPOSED SYSTEM:

Vendors and operators have to work hard with the highest efficiency and effectiveness .Requirements management tools helps to achieve this goal. As there are different tools suitable for different systems and industry, we are focusing on tools that support requirements management and trace requirements links between different artifacts.In the proposed system, we are going to compare different set of tools that are not compared in the above papers. Different tools have different features and functions. Requirements tools like top team, Caliber RM, Rational Doors, Requirements composer, cradle, requistie. The features that these tools support in common and their differences are identified. The comparative study has been made to determine the essential requirements tool that tops among the selected tools. We believe, these are the best criteria to test the requirements management tools.

OVERVIEW OF REQUIREMENT TOOLS:

There are huge number of requirement management tools which exists in literarture. Here we present some of the tools which are most likely used in many areas.We present their various supporting features of each tool which is helpful for any requirement manager to choose the appropriate tool.

The list of tools are discussed below:

Caliber RM

Caliber RM is a requirement management tool initially developed by Borland. It is designed to facilitate collaboration, impact analysis, and communication process.

It keeps a record changes ,so it is possible to go back and see what the changes have been made to the requirements.

CONCLUSION:

In this paper we have analysed the commonly referrers software requirement tools .we have compared various tools features used by each tool. No tool supports full automated works some works has to be done manually for good presentation of requirements. Each and every tool has some strong and weak points.Rational DOORS supports most criteria and has best and wide benefits for requirement management tool. Because this tool satisfies both functional and non functional requirements .

As a result of our study, we suggest that there is a possibility of huge potential in this field to gather ,elicit and validate requirements. We hope the result will help developer to develop right tool to overcome drawbacks and benefits the developer to choose the most appropriate tool.
