Computer software is used by hundreds of millions of people daily. Software is all around us and can be found in our homes, businesses, schools and automobiles. Operating system software runs our desktops, laptops, and mobile devices such as iPhones and iPads. The development of these and other complex varieties of software often follow a software engineering process commonly referred to as a Systems Development Life Cycle (SDLC). Several methodologies describing the framework that encompasses the subsets of the tasks or activities that occur during this procedure exist, including
Rapid Application Development (RAD) and Joint Application Development (JAD). Understanding the differences and similarities between RAD and JAD methodologies can allow organizations such as sanofi to make more informed decisions as to when and which software development projects they might best be utilized on. Additionally, having a firm grasp of the characteristics and context of the business problems the software is to address, may help in ensuring the most appropriate methodology is utilized for the mission at hand. Understanding why RAD may prove more valuable in a development setting, such as research is vital to software development in the Pharmaceutical Industry; in order to build the right software as quickly as possible while controlling costs and minimizing waste and inefficiencies when undertaking systems and software development projects.
Joint Application Development, sometimes referred to as Joint Application Design was developed for internal use at IBM by researchers Chuck Morris and Tony Crawford (Soltys & Crawford, 1995). It applies facilitated techniques that can be an effective tactic for eliciting and developing the require...

...are well understood, one can then select the most appropriate approach for development of their software; whether that is JAD with its formal processes and face-to-face group sessions or RAD with its iterative attitude to prototyping.
Also, looking at multiple dimensions, including how quickly the requirements can be elicited and understood by the team and having a clear understanding of the role of the system architecture ensures the most appropriate methodology is utilized for the mission at hand.
While knowing how to apply the appropriate method proves more valuable in a development setting, such as research. This is vital to software development in the Pharmaceutical Industry in order to build the right software as quickly as possible while controlling costs and minimizing waste and inefficiencies when undertaking systems and software development projects.
The Software Development Life Cycle is seldom used at my place of work. Unfortunately, recent developments in its use are deemed confidential. Due to this fact, this paper will examine in general terms one of the projects we are undertaking right now while at the same time attempting to maintain our confidentiality.
Controlled Requirement Expression (CORE) was developed for the British Aerospace programs while the UK Ministry of Defence was carrying out a requirement analysis (Hull et al., 2010). The fundamental component of the CORE methodology is viewpoints as different users see systems in different ways. There are many different stakeholders involved in a system; using CORE methodology involves finding all the different viewpoints of those stakeholders that have an interest in the system whether it’s a person, role or organisation ext.… (Sommerville and Sawyer, 2000). By organising viewpoints hierarchy it assists experts to read the scope and supports the analysis process. CORE Methodology is extensively used for real time system requirements specification.
The software development life cycle (SDLC) is a framework defining tasks performed at each step in the software development process.

Among the factors listed in Exhibit 10, we weigh the following heavily: Training and Support as the ultimate utilization of the software will be by the end users and their ability to use it will have an immense effect on the success of...
Analyze the impact of the factors: If the factor will change, which of the following would be affected other design decisions. Identifying issues: An issue may arise from factors in many ways: limitations , constraints reducing the impact of changeability ,difficult-to-satisfy product factors common solution to global requirements Develop solutions and specific strategies: Discuss a general solution to the issue, followed by a list of associated strategies. Strategies should address the issue and one or more of the following goals: reduce or localize the factors' influence reduce the impact of the factors' changeability localize required areas of expertise reduce overall time and effort Identify related strategies: When a strategy belongs to more than one issue, describe it in one place and reference it as a related strategy in the other issues where it applies.

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.
In every project there are always some universal characteristics that will be shared. They all have a comprehensible and established purpose and very distinct life durations. Overall, all projects are doing something that may possibly be new or yet a one time endeavor but have explicit requirements which include; time, price, and performan...
This paper has the intention to explain what Rational Unified Process (RUP) is like an IBM product and a CASE tool. After is explained what phases it has, what are the most common extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a software design method created by the Rational Software Corporation and now is part of IBM developer software. This paper describes how to deploy software effectively. The Rational Unified Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence particularly applicable to larger software development teams working on large projects.
Williams, (1997) identified four steps to system planning. Earl (1989) proposed five alternate strategy frameworks which project managers should consider when deciding how the system will enhance the business function. Standard business strategy methods are used to identify such opportunities by using: value chains, application searching and information analysis (Earl 1989).
Multiview is an approach to system analysis and design and is accomplished by breaking view specification into independent tasks. It focuses on organisational goals and aims to further them by integrating the system in accordance to the people that work within the establishment.
In this chapter I will discuss about the methodology of this project. Several methods are used to determine the research objective. Methodology is a systematic way to solve a problem. It is a science of studying how research is to be carried out. Essentially, the procedures by which researchers go about their work of describing, explaining and predicting phenomena are called research methodology. It is also defined as the study of methods by which knowledge is gained. Its aim is to give the work plan of research. By understanding and using the appropriate methodology in developing the research, it will be easier to achieve or accomplish the system development objective.
Software engineering encompasses various principles from both the computer science field and the computer engineering field to develop practical uses of software within hardware we use on a daily basis. With the passage of time, technology dependent on software has become increasingly prevalent. As a result, there will be a high demand for software engineers to sustain the eventual abundance of new and more complex computers.
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.
