Professional Writing in Computer Science Essay

Analyze user needs and develop user requirements and convert the requirements to required functionality. ("Systems development life,”)

Ones the requirements are collected a target can be planned but it can also very difficult to know form the beginning how the project will be looking because changes are welcome in any stage of the development. Changes can occur during the development process which can change the whole process but is also very flexible. A strong developer and customer can be established during every iteration which can help to identify the user needs and make clearer about project and what the user actually wants from the project and what his or her expectations are. Faults can be detected in better because of the

|The intent of requirements engineering is to produce a written understanding of the customer 's problem. |

The paper is a case study analysis of 16 US software development organizations that adopt agile methodologies. The authors aims to provide a more comprehensive understanding of this approach based on the detailed analysis of its practices and how it impact different risk area in the realm of Requirement Engineering (RE). The use of traditional Requirement Engineering recommendations and guidelines in agile development is most of the time problematic and infeasible. These challenges have resulted in the use of different agile practices. The empirical study has identified six agile practices: (1) face-to-face communication over written formal specifications. (2) The iterative nature of requirement engineering process. Only

A Software Requirements Specification (SRS) is a complete description of the behavior of the system to be developed. It includes the functional and nonfunctional requirement for the software to be developed. The functional requirement includes what the software should do and non functional requirement include the constraint on the design or implementation of the system. Requirements must be measurable, testable, related to identified needs or opportunities, and defined to a level of detail sufficient for system design.

Software engineering is a newly developing engineering discipline that the world is looking at as a solution to many problems that are currently being faced in software development process. The main question is why software engineering needs a theory and whether or not this engineering discipline has theories in place to standardise the way that software systems are currently being developed to ensure greater benefit to the clients while delivering the software on time, within allocated budget, and with no defects. This paper explores existing software engineering theories and justify the need for a theory in software development process.

The title of the paper upon which this assignment is based is The Meaning of Requirements. The paper was written by Michael A. Jackson, an independent computing consultant in London, England and visiting research professor at the Open University in the UK. He is credited with some 19 publications in the field of Requirements and Specifications alone. His fields of study also include Software Engineering and Development, Problem Frames, Information System Development and Sequential Program Design Information.

That is why it is important to involve the user when determining the requirements for the system. The more closely a software product meets its specified requirements, and those requirements meet the

Requirements Engineering (RE) is and very important phase in the software development because it is this process that gives us a base for the overall software development process. This process gets even difficult and it requires more attention when the stakeholders are separated in different geographical location and have different languages and live different cultures. Requirements engineering deals with getting the needs of the customer understand the requirements of the system to be developed. In this process we also have to understand the constraints and adapt to those constraints during the process. Global Software Development is making the practice of requirements engineering a vital one. D. Zowghi, (2003) states that as software development has progressed today, it can be said that

The waterfall approach to software development projects is a linear model, which focuses on individual stages of development including, requirement identification, analysis, design, coding, testing and operations. While this model has been around for decades, there are many drawbacks. This method heavily focuses on extensive documentation and front loaded requirements gathering; thus inviting the opportunity for significant and costly failures. As the landscape of information technology in the business world has evolved, we have seen a major shift from complex back end systems that didn’t include input from stakeholders and only programmers could understand, to computer programs that are customized to the front end users and other

This is not the inherent nature of software development projects. Software development project requirements are frequently changing. This is often a result of client feedback and input paired with a changing market. The waterfall method does not account for either of these factors. Successful projects must evolve during the development projects in order to meet client requirements upon implementation. Thus a development process must be flexible enough to adapt to changing requirements.

Requirements engineering is a traditional software engineering process that aims to identify, analyze, document and validate requirements for the system to be developed. It is the practice of eliciting, analyzing, prioritizing, negotiating, and specifying the

Requirement elicitation is a critical and essential activity in the requirement engineering processes. It is a finite set of activities that complied in determination process of the system requirements. This includes identification of the system’s stakeholders, analysis of the current problem definition in application domain, an operating environment of the system and of all customers’ business and organizational environment. One of the major aspects in the failure of software projects is an improper system requirement.

In the requirements gathering and analysis phase, requirements are gathered in this phase and are analyzed for their validity. A document is created which served as strategies for the next phases.

Classifying requirements according to attributes also helps team members who have different roles to view requirements from different viewpoints. For e.g. Developers may want to view requirements by difficulty and testers may want to view requirements by priority.
