Janice Gould of Krebs Consulting is in the process of making a recommendation to a client regarding the corporate-wide purchase of an analytical software platform. She has made the following estimates on management’s most important performance criteria and has rated three Software packages across these criteria Assume that the client changes their mind and now argues that the maintenance and support criterion is already accounted for by the total cost criterion. Further, the client asks Ms. Gould to drop maintenance and support and add its factor weight to total cost. Will this client request alter the recommendation?
3. Assume that you signed up for freelance service for the first time. To prove your capabilities, you decided to add some dummy software development projects as showcases of your work. In each project, you proposed that a client has contacted you for a program, application, information system, or app to be developed. Thereby, you and the client need to agree on the boundaries and type of the project you are about to accomplish. In this task, each student can select a software project from any domain, size, or type. Each student must write and submit the following: 1- A description of the software project, and 2- include a problem statement that explains the problem which the project will study or solve.
A gradual approach to implementing new functionality, beginning with a basic set, then adding more advanced functionality after users have had a chance to adjust to the new system is a good idea because: Group of answer choices Users can get new ideas for advanced functionality once they have a chance to use the basics of the new system. This approach allows for an iterative approach to be taken to fix issues and make improvements to the new system. It sets in motion “the journey” of continuous improvement and process redesign using the new system. All of the above.
Develop a general spreadsheet implementation of in term ediate COCOMO. You should include a percent software reusability as part of your general model. Also, input labor and overhead rates to get a total cost model. This model should be general enough to be used as a first-cut software estimating tool. The VLOOKUP function in Excel could be a great help in developing a general model. 7.3 You are developing a new IT application that must operate within a strongly coupled complex environment of hardware, software, and operational procedures. You are in charge of estimating the development and installation costs of the data collection system. Given the following information, estimate the total cost of the system: 1. The system will consist of the following components: a. Three COTS servers at $9000 each b. Two COTS sensors at $13,000 each c. 10 KLOC to integrate the systems 2. Your company uses the following rules of thumb when estimating costs: a. The total project cost is…
Requirements analysis is the process of determining the users' expectations for a new or changed application. It encompasses all activities undertaken to ascertain the demands of various stakeholders. As a result, requirements analysis refers to the process of analyzing, documenting, validating, and managing software or system requirements. High-quality requirements are documented, actionable, quantifiable, testable, and traceable. They aid in the identification of business opportunities and are established in such a way that system design is facilitated. 6.1 Discuss the importance of systems analysts documenting user requirements.
First Rules of Programming A Quality-Assured Operation User needs may be prioritized via deployment (QFD). An overview of QFD methods and an illustrative case study are required.
Compulsory TaskAnswer the following:● Briefly describe possible quality standards that might be used for thesereal-world products:○ Mobile game app○ Banking application○ Database for a medical organisation● Explain why a high-quality software process should lead to high-qualitysoftware products. Discuss possible problems with this system of qualitymanagement.● Explain why program inspections are an effective technique fordiscovering errors in a program. What types of errors are unlikely to bediscovered through inspections?● Why is it difficult to validate the relationships between internal productattributes and external attributes?
Identify an information system frequently employed by people in a career field you are interested in. Discuss how you might be involved as a user in the development or acquisition of such a system for your future company. Identify three things that you could do as a project participant that would greatly improve the likelihood of a successful project. Now, identify three things that you could do (or fail to do) that could greatly diminish the probability of success of such a project.

You are gathering requirements for a new version of an existing product that is presently being developed. List one elicitation approach that would be successful in resolving each of the following section's needs elicitation problems (one technique per problem). Briefly explain why this technique is suitable in this circumstance. Rather of just listening to what users claim they do with the existing system, you should examine how they really use it.To accomplish so, you must first determine which elements of a new proposed system are the most important and necessary.
Question 4 Open source software is developed software with source code that is publicly available, under an open source license, andis open for anyone to study, change, and improve its design. If a company adopts this approach for software development,discuss the issues concerned with licensing of this software. Question 5 A prototype is an initial version of a software system that is used to demonstrate concepts, try out design options, and findout more about the problem and its possible solutions. Discuss this concept in detail outlining the benefits as well as theprocess activities. Question 6 Requirements engineering is a systems and software engineering process which covers all the activities involved indiscovering, documenting and maintaining a set of requirements for a computer-based system. Provide a detailedexplanation for functional and non-functional requirements
Computer Science You have finally made it! This week, you will submit the last piece of your project. Identify if there are any business process changes, provide a high-level timeline, write up a recommendation, and provide your proposed solution. These are items 8, 9, 10, and 11 of your template. You should also complete the overview of your project (there is a heading at the template, under which you should write your project overview). The overview should include what you found out from your analysis and if you think you should proceed. The findings you have come up with will be fluid and will evolve but giving your management team or whoever you are presenting to an idea of what to expect, always helps get funding approved faster.
