- Summarize and cite related work by others; compare your methods and results with others’ work.arrow_forwardA thorough breakdown of the wait-and-see strategy is provided. What are the main disadvantages of this kind of interaction? Create a formula to determine the amount of time spent connected using this case study.arrow_forwardAssume that you have the situation in which: • Suppliers can supply products for projects. • A supplier can supply a particular product for multiple projects. • A product for a particular project can be supplied by multiple suppliers. • A project can have a particular supplier supply multiple products. • A supplier has a key attribute supplier_ID, a project has a key attribute project_ID, and a product has a key attribute product_ID Draw an ER-diagram that captures the above description. You must also include the quantity and due date for supplying a particular product to a particular project by a particular supplier.arrow_forward
- Prepare a weighted decision matrix using the template named wtd_decision_matrix.xls from the templates provided below in this assignment. Ben listed in the Cloud Computing Case will use this matrix to evaluate cloud providers for this important project. Develop at least five criteria from the link above, assign weights to each criterion, assign scores, and then calculate the weighted scores for four cloud computing providers (e. g. Amazon, Microsoft ,HP, etc.) Write a brief report that describes the weighted decision matrix and summarizes the results for the cloud provider you have chosen. Use the link provided above this assignment in Canvas to help you develop criteria to evaluate the cloud providers you have chosen. https://lts.lehigh.edu/services/explanation/guide-evaluating-service-security-cloud-service-providers https://www.zdnet.com/article/the-top-cloud-providers-of-2021-aws-microsoft-azure-google-cloud-hybrid-saas/ Weighted Decision Matrix for Project Name Created by:…arrow_forwardUnderstanding will be aided by drawing the project's map both with and without its core architecture. Considering the effect of the finished work.arrow_forwardThink about the following example: A manager responded to your effort to explain the idea of weighted assessment models by asking: "How do you decide the weighting elements, then? Is it simply my opinion based on my best guess?" What would you respond with?arrow_forward
- For each of the scenarios below please describe what would be the best design pattern to be used, explain the appropriateness and advantages of using that pattern, and draw a corresponding design diagram for that scenario including that pattern. Describe the participants and collaborations. Please respond to all of the above 4. There is a system configured to work with three pretzel stores: Pretzel Maker, Wetzel, and Auntie Anne's. They create similar yet custom-made pretzels, and the system needs to be independent from the way the pretzels are created. Each pretzel store uses its own ingredients (products), yet similar to the other stores. They each use their own kind of dough, cheese, and sauce.arrow_forwardThe decision tree structure that you built suggests three possible outcomes for a project. Which of these three outcomes would you recommend for implementation in the project? How do you think the most successful technique is for obtaining information and analyzing alternatives is from your perspective?arrow_forward
