Title : The Role of Requirement Engineering in Software Development Life Cycle Author : A. Chakraborty, 2M. Kanti Baowaly, 3 A. Arefin, 4 A. N. Bahar Article summary There is a great importance given to the requirement engineering stage in the SDLC(Software Requirement Life Cycle). It is the backbone which governs all the subsequent processes. Further post requirement defects would largely contribute to the failure of projects, exponentially increased cost etc. In this phase the mission needs and user requirements are received from the client and they would be converted to operational requirements and subsequently to System requirements. Based on system requirements the system would be designed and at the end the system will be developed and tested. Each system requirement should have the traceability with operational requirements and user requirements/ mission needs received from the client. Further if the requirements are not elicitated correctly it would impact the increased client dissatisfaction and would result in losing business in the future.. Therefore it is vital systematic requirement engineering process is followed. It is equally important that during Requirement process a very high attention is given to the validation process. The validation of the requirement must be carried out with different stake holders . There could be different stake holders who have different interests in the project. During the validation process of the requirements if all hidden , missing requirements or any gaps were not identified, later in the project it will contribute to scope creep. Therefore at the project inspection all the stake holders need to be identified and grouped at upfront. If not there could be a... ... middle of paper ... ...g systems), 2nd ed.: Prentice Hall, Englewood Cliffs, NJ 2003 Elli Georgiadou, "Software process and product improvement: a historical perspective," Cybernetics and systems analysis, vol.39 (1), pp. 125- 142,2003 Court I., Ross M. and Staples G.

ISO 9001 is a quality management standard that helps a company or an organisation to continually monitor quality across all operations. As an internationally recognised quality standard, it outlines ways to achieve, as well as

Business requirements are gathered in this stage. This stage is the main focus of the project managers and stake holders. It is performed by the senior members of the team with inputs from the customer, the sales department, market surveys and domain experts in the industry. This information is then used to plan the main project approach and to conduct product feasibility study in the economical, operational and technical areas. You identify needs of the software. This is the vital stage, because bad investigation may lead to the project

This includes taking the deficiencies in the existing system and addressing them with specific proposals for improvement. These proposals can be to ensure that the new EHR has all the necessary requirements to qualify for certification and help to narrow down vendor selection. Incorporated into the SDLC is a maintenance phase in which constant upkeep and evaluation is needed to ensure an operational system that is properly maintained, supported and secured. During this phase, system users should be kept up-to-date about the latest modifications and procedures. It is therefore important to know that your vendor has a good standing reputation and plans to provide continuous support for your software throughout the product’s lifecycle.
Quality of products and services is paramount and as a result, Manutec has been awarded ISO EN ISO9001:2008 quality standard.
The total quality management is valuable asset for Longxi providing it was an competitive edge over most of other competitors. However Longxi needs to improve the quality control system further to meet industry accept standard, i.e. ISO9002 to expand further into the overseas markets.
The system development life cycle, also know as the SDLC, is the process of designing and developing a system or software to meet certain requirements. (“System development life,”). This cycle involves many different phases, in which the system is planned, analyzed, designed, implemented, and tested. There are five major phases in the system development life cycle: systems planning, systems analysis, systems design, systems implementation, and systems security and support. Each of these phases has a particular responsibility and certain tasks are perfumed in each phase.
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).

Requirements phase: The team will identify the key security objectives for the product set the appropriate bug bars that define security and quality for the product lifecycle and perform security and privacy risk assessments.
In past few years, companies and industries of various sizes have become aware that they need to improve business processes such as product development, order fulfilment, planning, distribution, and customer service. So everybody is now focusing on doing process improvement or redesigning.
Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...
It is known as ISO 9000 family and the ISO 9001 is the one which is concerned about the requirement of the QMS. Of course, that creates the needs for understanding these standards in order to get the certificate from the organization which is authorized by the ISO. That also creates the need for the training which is very important for companies to implement the QMS. The standards have been developed the course of the quality history from needing a quality control to a quality assurance. Basically, implementing a Quality Management System is important for companies to succeed in today’s market, and will enhance customer satisfaction, and improve internal process. It becomes more and more a necessity for international companies because it saves a lot of money in one hand and time in the other. Nevertheless, implementing such system requires an effort, training, and using consultant companies to ease the establishment of the system and to get the certificate eventually.
Software engineering is important in today’s society because we use the products of software engineering almost daily. We use the products of software engineering in objects as simple as our car keys to objects as complicated as supercomputers. The past, present, and future of software engineering is quite interesting. This paper will provide information about this field of study and why software engineering is going to be around a while.
