SLDC vs. JAD vs. RAD
Methodologies of Software Development

Kaplan University
IT460 – System Analysis and Design

From my reading I learned that Software Development Life Cycle (SDLC) follows a pretty general process that is used by a lot of project managers. The whole purpose of SDLC is to create a better product than is planned for while meeting time and cost figures (Tutorials Point). the Chief Information Officer (CIO) asked to look at a couple of methodologies. The two methodologies are JAD (Joint Application Development) and RAD (Rapid Application Development). JAD (Joint Application Development) is a methodology where you use the client and end users at different points during the project (Rouse, 2007). By using this methodology some of the advantages are that in a short time frame you can gather and consolidate a big amount of information. Another benefit is that you can look at many points of view on the project and can resolve discrepancies in a timely manner (n.d.). Some disadvantages of JAD (Joint Application Development) it takes a lot of planning and scheduling and this will also require a lot of time from the stakeholders. Another disadvantage is that people that are working on the project have to be trained and experienced with what the project requires. RAD (Rapid Application Development) is a methodology that is focused on producing software quickly. This is done by using prototypes that have been established before and uses tools that are specifically designed to produce software. The biggest thing is that this methodology is focused on producing a prototype and not a full application (Janssen). Some of the advantages of the RAD methodology are that it decreases the overall development time because you are integrating right from the beginning. You also get the advantage of being able to reuse a lot of the software…...

...Unit 3: SDLC Phase Natasha Joseph Kaplan University Professor Michael Renick IT460: System Analysis and Design July 20, 2013 Unit 3: SDLC Phase In the past Jesse and the team considered using a JAD session to gather requirements but this time around the decision has been made to gather the requirements through an interview process. An interviewing process is a fact finding tool used to obtain information from another person, however to be successful at interviews you must possess the “skills needed to conduct, plan and evaluate interviews successfully” (Cashman. Pg155). The team assumes that the interview process will give them a great start. This paper will give Jessie an outline of what processes will be followed to ensure that the interviewing process is successful; a list of team members to be interviewed as well as their job function within the company will be provided along with interview questions for each person. The end product will be a summary of how I will publish the results. Question 1 The processes that I will follow to ensure that the interviewing process will be successful are as follows: 1. Determine the people to interview: In other to determine the people to interview you have to consider the work that you need done. Selecting the right person to interview and asking them the right questions can be a plus because you need as much information as possible to make your project successful 2.

...Unit 3 Assignment Kerry Bridges Kaplan University IT460 Unit 3 Assignment ITEM 1 – INTERVIEW PROCESS: 1. Determine the people to interview To obtain the information I am looking for, I will need to interview key members of the organization. These members will need to be knowledgeable of their respective positions. I believe it would be best to talk to the department heads and their middle managers. I will also interview people on all levels in the organization. I will also interview multiple people in the same department. My reasoning for this is that everyone has their own strengths and specializations. 2. Established the interview objectives After determining the people to interview, I will establish the interview objectives for the session. I will determine the main topics to be discussed and come up with a list of questions and concerns. I aim to obtain ideas, suggestions, and opinions during the interviews. There will general questions asked to every person in their field. By establishing the objectives I will create the guidelines that will help to determine what questions are needed to ask. These guidelines will also determine how the interview will flow. 3. Develop Interview Questions I will create a baseline for the list of question. This will ensure that the interview proceeds smoothly and that the people being interviewed stays on topic. The questions will be specific to the topic. I want to make sure that the questions are both......

...Running head: INTRODUCTION TO PHILOSOPHY Mary Graham American Intercontinental University PHIL201-1304B-11 Nov 17, 2013 Metaphysics is the attempt to say what reality is. Cosmology or how we think the most real things have come into being and ontology the study of what is. To me what is real the things you can touch, smell, see etc., but you also have things that you can’t see that is real. For example God is real; people believe that the earth is flat etc. We can’t see these things but we believe they are real. The physical, spiritual and psychological worlds are in twine with each other. First of all physical worlds known to humans through their five senses are complemented by the spiritual world or simply spirit world. This is not an imagination but a complete real environment for the human spirit. The spirit world is a separate existence but it interface with the physical world. The humanity aspect of the spiritual world causes a dysfunctional aspect to the psychological impact of the human nature. There are many people who are distant from God and unaware of their conscious evolution to the spirit world and how it operates because of the physical being that is temporarily in this world and so they are not prepare for the spiritual world which is eternity. To me a soul is real but as far as the soul living outside the body no one knows for sure. Some people believe in a soul and some may not. I believe people have free will and our fate is determined......

...Unit 2 Assignment Kaplan University IT460 – System Analysis and Design Part 1: Intranet and Competition Jesse, I was able to get into the intranet and got a chance to explore some of the information you’ve made available. In the data section I found a summary of the company’s organization, the training calendar, a script for a typical JAD session, and some sample documents. I also looked through the company forms such as our Service Request, Report Analysis, and Documentation forms. Finally I looked through the resources library which seems to contain the tools and vendors that the company uses. I can see how this will be an invaluable tool for my work here. As you requested I found three other IT consulting firms that may be of interest. The first I looked at is ClearPointe, who primarily focuses on Microsoft System Center and NOC services. They provide managed services for systems such as Active Directory, Exchange, and Lync. The next company I found is Complete Computing. They provide managed Microsoft services like ClearePoint, but also have a strong training and support side. The last company I looked at is Cireson. They focus on System Center and automation consulting. All three companies focus heavily on Microsoft systems, with Complete Computing seeming to be the most well rounded in their service offerings.

...1. At a company, you are responsible for securing a network server utilized primarily for data storage and internal application sharing as well as for securing numerous desktop computers connected to the network. Describe the access control that you would put in place for each and explain why. The more valuable your data, the more effort you should put into securing your firm's network servers. The following areas will help to maintain a server on the network. Firewall: It's important to ensure your server's built-in firewall is running and that you are also using at least one level of network firewall. This may be something as simple as a firewall on the router attached to the server. Placing a server on a network without a firewall is like leaving the front door wide open. Once the firewall is running, the next step is to turn off every port you don't need. If you are not using the port, you don't need it open on the firewall. Hardening: Getting the firewall running is only a start. A critical step is "hardening" the system. This is the process of trimming the machine of every piece of software it doesn't need to complete its assigned task. Every single piece of software is going to have an exploit. You want to reduce the machine down to the necessities to increase the security. This means removing software from the server box. If, for example, the machine is an e-mail server, then delete all office productivity applications, the Web browser, even games......

All of these items will be used to combine into one comprehensive report. Introduction In this assignment I will one section of qualitative data (choose either Gender or Position) one section of quantitative data (choose either Intrinsic or Extrinsic) and provide data. In each section the data will be indentified and the reason for the selection will be stated. Charts and graphs will be provided. An explanation of the importance of charts and graphs will be stated. Chosen Variables The variables that I chose to analyze are gender for my qualitative variable and Intrinsic for my quantitative variable. Difference in variable types “Qualitative data are no numerical measurements of characteristics, such as hair color or the charge of electron. Quantitative data are numerical measurements like weight, height, and age. The two data types need to be handled differently because qualitative characteristics don't have clear mathematical relationships to one another.” (Elementary Statistics) Descriptive statistics: Qualitative variable |Position |Tenure |Job Satisfaction |Intrinsic | |1 |3 |4.9 |6.4 | |1 ...

P1. Describe the type of business, purpose and ownership of two contrasting organisations. The name Oxfam comes from the Oxford Committee for Famine Relief, founded in Britain in 1942 due to relieve famine in Greece caused by NazilGermany military occupation and Allied naval blockades, and registered in accordance with UK law in 1943. Oxfam International was formed in 1995 by a group of independent non-governmental organizations. Their aim was to work together for greater impact on the international stage to reduce poverty and injustice. Oxfam International is registered as a non-profit foundation at The Hague, Netherlands. So Oxfam does not have ownership, it is run by Board of Directors and if the business does close down it will give it charity stuff to another charity. This business is not set up to make profit for it personally need it is set up to make profit for people in need. Oxfam gets its money from many different sources: * like the shops that people can go to * people donate their old and unwanted clothes and items and Oxfam sells it to us, the consumers * they also get private donations given to them by people who want to help Oxfam is an international confederation of 17 organisations working in approximately 94......
