Which of the following statements are true about the Rapid Application Development (RAD) and the waterfall methods of the system development life cycle (SDLC) ?
ANS-
1- In SDLC we have 8 models in each one of the eight waterfall is the older one.
2- Only waterfall model has requirement/analysis phase.
3- Waterfall model has fives phases like-
- requirement/analysis phase
- design phase,
- unit testing,
- system testing
- , operation and maitenance phase.
4- More new method has been introduced so it is not best choice for future projects.
5- As RAD is newer one so it delivers fast in comparison to waterfall.

- The SALTAAROLHA, Lda recently completed a set of plans for the development of a new application for a Ministry, with Dr. Hermano Granel being responsible for the project in the design phase and in the development and construction phase.Having already been modestly done the requirements design and analysis phase, his problem was how to process the transition from the design phase to the development phase, selecting the most convenient development process for the case.The project presented a high complexity unfolded in a set of 10 different modules,very difficult to integrate. The deadline for completing the development of the application was 120 days, which was clearly too short for a single team (whichHermano Granel had) to meet.The client had great urgency in the application but since it was a state entity, could not allocate more budget to the projectMoney was a problem ...What advice would you give to Hermano Granel in selecting the software development process model? Why? What…Please written by computer source Question 1 Outcome 3 in INF4817 relates to software engineering tools, in this module outcome a review is done of their purpose and effectiveness. The following questions pertain to software engineering tools. 1.1 Give a brief history of the establishment of the OpenMRS project as well as a brief overview of its technical architecture. 1.2 Sustainability is an important consideration in projects implemented in developing countries. Often projects in developing countries will be initiated after initial funding from a donor funder, however it is important that a project continues even after the initial donor funding ends. Sustainability also relates to technological aspects of a project, they too should ensure that a project persists beyond the initial implementation. The phenomenon of “pilotitis” relates to information systems projects implemented in developing countries that are piloted using initial donor funding which however do not go beyond the…28. Which of the following life cycle model can be chosen if the development team has less experience on similar projects? a. Spiral b. Waterfall c. RAD d. Iterative Enhancement Model
- Which of the following statements is NOT true a. In designing an AIS, the design team will begin with outputs b. Implementation, follow-up, and maintenance of IT includes acquiring resources for the new system c. The more work done during planning and analysis, the less likely the new system will fail d. A preliminary investigation of a current system is conducted by the steering committeeWhich of the following is NOT true about use cases? Select one: a.Use case specifications are developed before the use case diagram. b.A use case can be brief, casual, or fully dressed. c. Actors are categorized into primary actors, supporting actors, or offstage actors. d. A use case contains a set of scenarios including the main success scenario and alternative scenarios. e. A use case describes functional requirements via interactions between an actor and the system.For the Professional and Scientific Staff Management (PSSM) case, answer the following questions: Q1. Are there any constraints about this project that need to be identified? Q2. What software development methodology do you recommend for the case above? Why? Q3. Add to the list of requirements based on what you have read and your research in the area. Please also add your sources at the bottom, so I can learn.
- Five software development projects are under your direction. The project's qualities are as follows:1. The website of a nearby business. little system. Requirements are vague and subject to modification.Project 2: A large embedded system with clear requirements.3. An "usual" business app. Similar systems that you've developed earlier. a hospital's administrative system in the area. All needs are steady, while some are confusing. Project 5: A small real-time management system for a neighborhood hospital.This list includes formal development, throw-away prototyping, evolutionary based development, and waterfall.What model(s) or strategy(es) would you use to your projects from the list above? Justify your choices.Here's a selection of system app themes to work on : Hospital inpatient system application 1.Determine between 5 to 9 functional requirements and 2 to 3 non-functional requirements that may be required in the application theme assigned to you. Set analysis limits according to your assumptions! 2. Determine the components of the use case modeling (analysis) such as actors, use case scenarios/descriptions, and use cases (processes) according to the chosen business theme.a. Draw a Use Case Diagram according to the assumptions in question no. 1 such.b. Write down 2 Use Case Description models for existing use cases, especially those involving transaction processes (transactions of inpatients in a hospital)! 3. Draw class diagrams for all possible data objects in the system application on the defined theme. The class diagram covers all aspects such as classes, attributes, relationships, and methods. As much as possible also include aspects of the hierarchical structure of inheritances…Evaluate the following action taken by the team during the validation. For each scenario, identify its appropriateness (of action taken) by writing ‘appropriate’ or ‘not appropriate’ then map the case with the related validation principles. 1. The requirements engineer conducts an inspection of the requirements as mandated in the process and invites system architect, a programmer, a tester, and a legal compliance expert as inspectors. 2. Since no other project member was suitable to moderate the inspection meeting, the requirements engineer decides to be the moderator of the moderator meeting. 3. The requirements engineer decides to conduct the validation only once due to budget constraint. 4. Before the validation session begins, the requirements engineer reminds all reviewers to immediately correct the errors found in the document. 5. The inspection team requests for additional development artifact directly from the author. 6. The inspection team…
- Please offer two examples of non-functional needs that you have devised on your own in respect to the component of the project that you are currently working on. These requirements should not be related to the functionality of the component.Which one is the right answer? 1. Generating alternative initial designs would most likely be done during which phase?a. Design b. Intelligence c. Implementation d. Choice 2. The difference between front and back office systems is a. Front office systems are external systems, back office systems are internal b. Front office systems are web based, back office systems are built on database systems c. Front office systems process information at the beginning of a customer’s transaction, back office systems process information at the end of a customer’s d. Front office systems focus on getting the sales, back office systems focus on follow up1. Requirements definition begins during the inception phase, extends heavily throughout the elaboration phase, and includes substantial technical details about model building. True/False? 2. The software engineering development process is the process of understanding and specifying in detail what the software application should do, what artifacts to develop, and who will work on the development tasks. True/False? 3. Systems analysis is the process of specifying in detail how the many components of the software product should be physically implemented. True/False? 4. A pure waterfall development process does not work very well always. True/False? 5. The iterative development process assumes that no one gets the right result the first time. True/False? 6. In the UP life cycle, the partially completed software is tested and reviewed with system users at the end of each iteration. True/False?
