Abstract This paper contains an analysis of various software process models. Software Process Models and related software development approaches with an example of each approach is considered – Sequential approach (Waterfall model), Incremental approach (Incremental Model), Evolutionary approach (Spiral Model), Specialized approach (Formal Methods Model), Agile approach (Extreme Programming Model) and RUP. This paper describes these models, as well as, it contrasts and compares between these different models.
I. INTRODUCTION
Today, the computer has become a very essential part of our life. It has become crucial as it is used in various fields, such as, education, commerce, industry, medicine and agriculture. Society have become more dependent

Waterfall model is one of the oldest models and is mainly used in government projects and it is widely used in many major companies and industries. As this model focuses planning in early phases, it confirms design mistakes before they develop the entire project. Moreover its intensive planning and document make it work well for softwares in which quality of project control is an important concern. The waterfall lifecycle contains of several non-overlapping phases, as shown in the following figure. This model begins with generating system requirements and project requirements and continues with various steps as mentioned above i.e. architectural design, detailed design, coding, testing, deployment and maintenance. This model serves as a baseline for all other lifecycle process models. The steps followed in this model are:
i. Communication: establishes the requirements of the stakeholders and then useful in project requirements gathering. ii. Planning: develops a precise plan of execution of the software. iii. Modelling: builds a model of the software before making the actual system. iv. Construction: develops the actual software following the plan of implementation defined in the planning phase and testing.
v. Deployment: the delivery of final-product to the buyer or customer and project’s

Delivery of increments is floundered as calendar time progresses. The first increment acts as the base product giving the functionality to address the core requirements. The floundered release theory permits for learning and giving feedback which can alter some of the buyer requirements in sub successive versions. This kind of approaches is useful when the entire complement of personnel need to finish The software is not available and when there is incapacity to fully describe the required project or to fully construct the set of
P1: describe the potential prompt that initiate the installation of new upgraded software There are different reasons that would prompt people to upgrade their software. This could be the response to a bug that is identified or it can allow the hardware device to run more efficiently so that it can improve the functionality of the software when you upgrade it. You must be aware of these prompts so that when a software upgrade shows up you should always act with them in an appropriate manner in some situations it is important for ensuring the security of your computer systems. Problems with existing systems PC can become slower or develop a fault and to fix it, it would be necessary to install new software on the computer.
The way we are going in a population that is constantly
In every community, ordinary citizens sit and watch 'parlor walls.' Teenagers and adults alike are driving at extreme speeds. Firemen now pour kerosene on houses to burn the books hidden inside of it. Furthermore, individuals overdose on medications and have to have their stomach pumped, a normal occurrence. People no longer pay attention to detail, such as the face on the moon and the dew on grass in the morning.
In this society, people are encouraged to pursue immediate pleasures and avoid critical thinking. This leads to a shallow and superficial society that is unable to understand complex issues or
This is evident through society because people are becoming much more lazy. Apparent through television shows such as, “My 600 pound life,” or even commercials such as the man asking the lady on the kindle how to set a timer to get his niece off, is showing how reliant people have become and how reading a book or a newspaper is almost unheard of. The internet is also morally corrupting the behavior of many people. With access to anything on the web kids are viewing things that are not appropriate for their age. Cyber bullying has also hit an all time high as people can express themselves over the internet in such an easy way.
However, time has continued and American values changed. What America once viewed as important has now fallen into the background and new values have come to the forefront. America no longer follows the rule of family first, but instead we follow the rule of work coming first. The value of the once meaningful family unit is deteriorating and work is taking its place.
Many people feel a growing disenchantment with modern life; that something fundamental is missing or ‘wrong’. Our increased material wealth is making us less happy, not more. Mental health issues are on the rise, and we face an environmental crisis. Somehow, we have lost our way. People long for a deeper sense of connection, a greater purpose, and a
Iterative and incremental approach is a better way of developing requirements and modules as well. 4. Requirements provide a complete operating picture of the solution, which helps in taking correct decisions during initial stages of software development life cycle (SDLC). Iterative and Incremental Approach This approach allows us to make changes before it is too late.
Today, we live in a world where we rely on other people for things. As a society, America has become a very lazy community. We strive for individuality but always rely on others to get the work
2. The scope of the application is pretty well-defined. There should be little to no changes to the requirements. 3. There is no need for iterative releases, since most of the requirements must be part of the application when released to
Most people are unaware of how change can make life better, but it doesn’t have to be this way. It is up to us to look upon it as something positive and learn how to use it to our own advantage and increase greater levels of

Throughout the history of western civilization there have been a vast number of changes that have occurred and wars that have formed civilization today. There have been economic changes, relating to the development of the economy and the financial state of society. There have been political changes, dealing with shifts in government and power. There have been social changes, affecting the organization of society and the interpersonal and international relations. All of these events have influenced society and molded it into what it is today.
Bigelow tries to argue that society alienates a person, but until people realize that separating oneself from a community actually creates that disconnect between common experiences he is so afraid of, we cannot successfully continue as a species. He states, “existentialists worry about the walls of industry and technology which shut us off from nature and from one another” (Bigelow). On the other side, it seems as though people fear relying on the safety nets that society has actually made for us in order to build up relationships and stay connected. This universal truth shows how society does not strip someone of their self, it actually allows for it. Life is so much more free in modern times than it was in the past, all thanks to the reforms society has made in order to let individuals thrive.
