A Computer Software Engineer develops software systems to be used by their clients, such as a website used to sell the client’s products. Although software engineers spend the majority of their time programming and testing the software, a key component to the success of a software engineer is the ability to write a thorough Software Requirement Specification (SRS). A SRS documents the requirements and dependencies needed for the software, prior to beginning any programming. Therefore, a Software Engineer must po The SRS is so important because engineers can have a wide scope of clients that they regularly work with. Audience A SRS documents the requirements and dependencies needed for the software, prior to beginning any programming. This document requires a two-way understanding that assures both the client and the engineer understand the needs and goals of the software. The first step in writing a SRS is understanding the client’s requirements, and then clearly documenting these requirements in terms the client can relate to. This is where correctly analyzing the client is very important on the engineer’s part because if the SRS is not right and the engineer did not understand the client, the program will not be what the client wants costing the company more time and money. Type of Writing and Communication According to the journal that was written by Lui et al., “correct understanding of the user’s requirements and appropriate design decisions almost always contribute considerably to the reliability of the software.” Appendix A shows not only the importance of the specification document, but also the importance that the specification document be reviewed and evolved several times before arriving at the final formal... ... middle of paper ... ...ware Requirements Specifications."

While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
Once customer requirements have been captured and analyzed, information of customer requirements needs to be translated into functional specifications and design. This activity involves marketing function, product designers and engineers.
It puts the requirement into perspective by explaining how it is used by the user and how the requirement being met will impact the system. This helps the analyst better develop their model while being prepared for potential changes and exceptions. A well-designed use case also helps future development of projects and more effective elicitation of requirements.
When I was in middle school, I had totally no idea of what Computer Science is, but I was pretty proficient in using computers at that age. The only thing that I knew about Computer Science is that one of my aunts is in that field and that’s all, nor of my parents are in that major. Not until in High School that I got the sense of what programming is like. I was taught basic simple codings and I really enjoyed it and thought that the class was actually quite fun. But the class didn’t give me any sense of the important real-world applications of Computer Science. Not until recently as I am in the Computer Science major, I started to really have the real idea and to gain real passion for the field. Computer Science is not all about programming.
The authors of this article begin by listing the main problems that are associated with large software requirement processes and then summarize how StakeRare will alleviate these through social networks and collaborative filtering in the elicitation process. This is a significant idea in utilizing technology in the software engineering process that have become more widely used since the creation of the more dated requirements elicitation methods. Large scale software projects are more likely to have stakeholders that are more spread out geographically and organizationally. This is due to organizations
The software testing is the critical element of software quality assurance and represents the Ultimate review of the software design and coding. The main objective of testing is to find an error and to uncover the errors that are not yet discovered.
• Maintain software systems in line with the business evolution by preparing existing systems for fruition as a set of services within a service oriented infrastructure;
A documentation framework is essential for any large project; hence, RUP describes how to document functionality, constraints, design decisions and business requirements. Use Cases and Scenarios, are examples of artifacts prescribed by the process and have been found to be very effective at both capturing functional requirements and providing coherent threads throughout the development and deployment of the system.
..., Handling, storage, packaging, preservation, and delivery, Control of quality records, Internal quality audits, Training, Servicing and also Statistical techniques. All standards apply to all types of industry sector whether they are large or small industry and also including design, manufacturing, service, research, development and also education. Unfortunately, this wide applicability also became a weakness of the model especially in the software development and maintenance industry. This is because, it is difficult in defining a common language that everyone in the industry sector can truly understand and apply. To compensate those problem ISO had published a new guideline specifically for software development that was ISO 9000-3.
The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
With information and IT systems being critical in a company’s success and superior systems allowing more efficient business processes and the opportunity to gain a competitive advantage in the industry, companies and developers tend to test software thoroughly and rigorously; and spend more than 50% of their time and resources within the testing phase to ensure systems are “bug-free” and all requirements is in accord.
