In this Research Paper I read
different books of different authors and visits lot of websites for the topic
of Engineering and Managing Software Requirements. And then I  explored 
the interdisciplinary nature of Requirements Engineering (RE) and
portrays the current status of understanding and functionality to  analyzing, modeling and managing of Requirement
Engineering activities and Managing Software Requirement for current as well as
future systems, with exacting emphasis on original ideas, frameworks and
empirical studies, and future directions of Requirement Engineering and
Managing Software Requirement  practice
and understanding.


Requirement Engineering
is that process by which the requirements for software are collected, analyzed,
documented, understanding, planning and then managed all over the Software
Engineering lifecycle. Requirement Engineering is concerned with understand the
user requirement and interpreting and understanding of stakeholder’s goals,
requirement needs and beliefs. There
are many other problems linked with Requirement Engineering that may lead to
incomplete requirements and incompatible cancellation of software projects/

Software developers understand that a
strong requirements management process is essential to the successful
completion of software projects to make worth in market and satisfy the clients
all expected requirement for which they want to develop that software or
As Requirement Engineering is best way to understating understanding,
identifying and articulating the role of business requirements which are
expected from stakeholders from diverse backgrounds with different needs.

Requirement Engineering is also a
management activity that manages different Requirement activities like
analyzing and monitoring products requirements and managing the project scope.
This research paper shows and describes to draw engineering and management features
to describe and analyzed issues that face the Requirement Engineering in the
third millennium.

Why a Research Paper?

Engineering and managing software requirements are main features and main
discussion for systematic software development to describe how to apply these
solutions to industrial practice and developing environments. Furthermore, it
provides collections of Requirement Research
and information about current industry practices. This
Research Papers describe few point, new insights into the software development
process for software developers. It also shows that Requirement Engineering is
also a management activity that manages different Requirement activities like
analyzing and monitoring products requirements and managing the project scope.

Background/Review of the State of the Art:

Requirements engineering is accepted
as one of the most critical stages in software design and development as it
addresses the critical problem of designing the right software for the customer
and fulfill all desired customer requirement for which that software or
application is established . Requirements engineering is progressively more
becoming a set of processes that operates on different levels, like
organizational product and project levels. The development of a software
requirements specification is widely recognized as the bases of system

Requirement Engineering is a
continuous process on organizational and product levels and a process limited
in time on the project level. However, most requirements engineering research
to date is devoted to handling requirements on the project level, making this the
main focus of this Research Paper. Software requirements are the critical determinants
of software quality as mentioned that errors in requirements are the most
numerous in the software life-cycle and also the most expensive and
time-consuming to correct.

What is a Requirement?

A requirement is that aspect that a
user or clients wants from developer for which purpose he wants to development.
So we can say that a Requirement typically refers to some aspect/features of a
new or enhanced product of service. Requirement is that condition that must be
fulfilled by a system to satisfy a contract.

610.12-1990 standard 24 defines a requirement as:  “A
condition or capability needed by a user to solve a problem or achieve an objective.”

Types of requirements:

These are types of Requirements like
Functional requirements and Non Functional Requirements

Functional Requirement: what the
system will do. Mean what will be functionality of software.

Non Functional Requirement: Non
Functional Requirements are that requirements that defines solutions that will
meet the functional requirement like accuracy, performance, security and modifiability.

Requirement Engineering Process prefers to
all life-cycle activities related to requirements in which include gathering,
documenting and managing requirements with significance of requirement in the
software process.

Common requirements engineering
activities are understanding, elicitation, and structuring, compromise,
verification and validation and to change management and requirements tracing.
There are several process models available to describe the requirements
engineering process.

The Role of
Stakeholders in Requirements Engineering, requirements
engineering aims to convert potentially incomplete, incompatible and differing
stakeholder goals into a complete set of high quality requirements. As software projects became more and more difficult, software
developers face
the challenge of identifying the goals of stakeholders who come from a diverse
range of backgrounds. The major problems in requirements engineering is the
management of different types of inconsistencies ensuing from requirements
specification, modeling, elicitation and prioritization activities.
Inconsistencies become mostly obvious when there are multiple stakeholders and
viewpoints, since different stakeholders have varying ways of express
themselves and different opinions as well as priorities.
