. State why it is a good idea to test a module in isolation from other modules and why different modules making up a software product are almost never integrated simultaneously? It’s a good idea to test a module in isolation from other modules to best identify and rectify bugs within each module. Also to it’s important that each module works properly on its own. In this way, problems are easier to identify and fix than otherwise would be the case.
Similar precaution is taken when integrating different modules. Such modules are rarely integrated simultaneously because the likelihood of bugs and problems slipping through unnoticed is much higher. By integrating module incrementally, each module can be tested as it is added partially and in turn,

The iterations are thus limited to at best an educated guess and if any change is necessary (which will happen) the whole model will need to be reworked, which is wasteful of time and resources. Iterations are limited because the waterfall model is limited. Without the assumed need for flexibility that other software process modules have built in, the waterfall model fails to take into account the usefulness of iterations in software development processes, which is one of the main reasons that it as a model is inefficient and out of touch with the realities of development.
3. Why is it increasingly irrelevant to distinguish between software development and evolution? Distinguishing between software development and evolution is increasingly irrelevant because fewer and fewer systems are completely new. In a way, then, development and evolution are talking about the same thing. Not only referring to maintaining already existent software or developing new versions based while retaining old code; much software that’s being development will borrow from extant software, evolving various parts into something new but not totally

Change is inevitable because technology, consumer demand, client need, and the amount of resources are always in flux. The demand for complex systems are in large part a reaction to the complexity of reality and as the world is always changing in complex ways, hence the need for continuously changing systems. I’d posit that this is a good thing, especially regarding what systems are able to do as technology has changed how we are able to live and function, I’d say for the better, and I assume that honing and advancing software systems will continue to make the world a better place.
Two examples of software process activities are design modeling, which documents the structure of the software which then helps honing and developing said software, and code refactoring, which improves code quality and makes it more ready to adjust to change. Both of these are essentially ways of making processes clearer and cleaner so that when change does occur, there’s a higher level of understanding and amenability. References:

What are your past experiences of being a staff member: I've been Helper, Mod , Admin and even Owner on different servers in the timeline of 3 years. And mostly on Faction servers. Not on hcf yet, but you need to start somewhere :D
After replicating in prod2. we found that user did not have access to the KRQCRSWRK (Coursework) milestone.
There are many reasons why I would like to be a staff, while I have played some days I see no Staff on the server, And there are people who spam chat with servers or people will abuse features or hack and scam as i as a regular player on the Cyclone Network cannot do anything about these problems/players. I really love this server and love the people on it, and I want everyone to have the experience I have had playing on the Cyclone Network server I don't want the server to be full of hackers, scammers, and abusers. If you ask most people who know me they will most likely say I am nice and caring, because
This article by Phillip A. Laplante and Colin J. Neill of Penn State University explores the rumors of the demise of the waterfall model. The Waterfall process model progresses software products linearly from conception, through requirements, design, code, and test (Neill, 2004). The Waterfall method was developed in 1970 by Winston Royce when computer systems were monolithic, number-crunching entities with rudimentary front ends and users’ needs were filtered through the partisan minds of the computer illuminati building the systems (Neill, 2004). Most systems built in that time did not pay much attention to input from stakeholders, which is a good environment for the Waterfall method to work in – an environment where requirements seldom change after specification due to the fact that users are not involved in the development and therefore cannot provide feedback regarding incorrect assumptions or missing features (Neill, 2004).

The first article I selected focuses on the Waterfall method of software development, entitled “The Demise of the Waterfall Model Is Imminent” and Other Urban Myths. Authors P. Laplante and C. Neill, take a conversational, slightly cheeky approach to dispelling the prevailing thought that the application of the Waterfall method was in steady, rapid decline. The Waterfall method is characterized by a methodical but rigid five step process to developing software:
During the module we have been put into teams but were also able to select our own teams. The aim was to prepare us for the future as in any job it is important to work well within a team. Also, it gave us the possibility to share ideas and have access to a wider range of knowledge. Furthermore it helped us to learn how to deal with a conflict that may have occurred
Modern Society has become overly complex, relying on an array of sub-systems in order to function.
| An adaptive method typically uses a spiral development model, which builds on a series of iterations.
Testing: It runs all the necessary testing to check the system if there is any problems or issues that need addressing.
Waterfall method is one of the traditional software developing method that has been implementing for decades. Usually, clients have requests, then software developers create an initial paln; after client approves the plan, developers follow through the plan; at the end, developers test and finish the task. Upon clients’ additional requests or tests, developers add up the extra features, but in most of the case, it would be too late or too hard to change. The entire process is not very communicative or translucent since clients and developers generally meet just once or twice throughout the project. In the article Why Making Software is so Difficult the author mentioned that software production is very
The traditional approach to software development can be illustrated through the waterfall model which is time tested and easy to understand. The waterfall model approaches software development in sequential manner, completing one activity before the other. It brakes up project in stages: requirement analysis, design, coding and testing, operation and maintenance (see fig. 1 below).
For the waterfall model, the rigorous planning prior to the project being started leads to a rigid design for the software (Ali, 2017, pg.16). The rigid design makes it difficult to accommodate for any changes that may need to be made along the way (Krishna, Sreekanth, 2016, pg.162). Ultimately, this could make the waterfall model risky as it has less flexibility (Dawson, 2014, pg.44). The waterfall model is not very suitable for projects where some requirements may be unknown (2,162). Unknown requirements may call for a change in another part of the project, which the waterfall model cannot tolerate (1,16).
When compared the Agile model with Waterfall model, the Testing of waterfall model starts only after completing the development. There are many issues and failures which are reported at the end.
When assessing the reason “the field is young”, one may surmise that newer developers may adopt more modern methodologies. Agile modeling came about after more traditional practices. However, less experienced developers may lean toward a more known and proven theory like the waterfall approach which uses successive phases to be completed and finalized. The waterfall is rigid but more predictable and may be easier to manage for new project managers. Using different types of techniques may confuse a
