Question 5
Step by step
Solved in 2 steps
- A financial organization is interested to develop an attendance system for its employees in a 6 month duration. The organization has been recording the attendance manually. Suggest the suitability of evolutionary software development processes with (suitable justifications) by filling the following table. Note: Replace the text (suggested process) with appropriate process name. Evolutionary Models 1-Prototyping 2-The Spiral 3-Concurrent Answer:When conducting engineering economic analyses, it will be assumed at first, for simplicity, that benefits, costs, and physical quantities will be known with a high degree of confidence. This degree of confidence is sometimes called assumed certainty. In virtually all situations, however, there is some doubt as to the ultimate values of various quantities. Both risk and uncertainty in decision-making activities are caused by a lack of precise knowledge regarding future conditions, technological developments, synergies among funded projects, etc. Explain the difference between decisions taken under risk and the decision taken under uncertainty.Suppose a software house is going to design an automated system to control the operations of an airplane. There are following requirements: o Cost-effectiveness o Reliability o Maintainability Suggest which one has the top most priority from the above. Also give appropriate reasons in favor of your answer.
- Please help me with this computer science homeworkQ: Software Quality attributes not always have positive relationship with each other. In this regard answer the following questions What are the quality attributes do you think testability is most in conflict with? What are the quality attributes do you think testability is most compatible with?There are different types of software testing techniques as described below. There is no uniform (standard) best software testing technique. Each has its own benefits. -Black box testing: based on functional requirements. -White box testing: ensure that all statements and conditions have been executed at least once -Manual software testing is time consuming -Regression testing: Software testing has to be repeated after every change Explain the following testing techniques and justify the statement - "There is no uniform (standard) best software testing technique." Please help with this question and explain in your own words to avoid plagiarism. Thanks.

- Scenario 4: TechPro Company is specialized in quick software development .A developing team received a new low cost project. As per project plan, it will take minimum 9 months to complete the final system; therefore, a team has decided to breakdown the system into small number of minimum cycles. Each cycle will have set of activities, which allow team members complete and review the code. Process Model: iterative Justification (Why?) ( introduction to software engineering))I need the answer as soon as possibleMaintainability is one of the most important software quality characteristics. Give the definition of software maintainability. It has been suggested that maintainability is influenced by the following software quality sub-characteristics: analysability, changeability, stability, testability. Justify this claim.
