Solved in 2 steps
- You are given the following scenarios. I dentify the problem related to software crises for a given scenario. Problem can be time slippage, Cost slippage, Faliure at customer site, Interactable error after delivery. Scenario A: Software for financial systems was delivered to the customer. Customer informed the development team about a mal-function in the system. As the software was hugew and complex, the development team could not identify the defect in the software. Scenario B: A polar satellite launch vehical was scheduled for the launch on August 15th. The autopilot of the rocket to be delivered for integration of the rocket on May 15th. The design and development of the software for the auto-pilot more effort because of which the auto-pilot was delivered for the integration on June 15th(delayed by a month). The rocket was launched on Sep 15th(delayed by a month). It is problem related to software crises. Please solve it.In spite of the fact that software is often linked with errors, the aerospace industry has been developing essential software for airplanes with a failure rate that is unexpectedly low. What procedures are followed, and how are they followed, to guarantee the creation of essential software that is free of errors?Reliability and safety are related but distinct dependability attributes. Describe two important distinctions between these attributes and provide examples showing how it is possible for a reliable software-driven system to be unsafe and vice versa. Reliable & Unsafe Unreliable & Safe
- There are frequently severe political repercussions when software requirements analysis (and/or system analysis) begins. For example, workers may feel that job security is threatened by a new automated system. What causes such problems? Can the analysis task be conducted so that politics is minimized?Use this game to design the implementation of the system needs described in the tales. When software performance and reliability are critical design goals, why may this method be problematic?The aircraft sector has been developing vital software for airplanes with a remarkably low failure rate, despite the software industry's reputation for defects. How are critical software programs developed in a way that prevents errors?
- You are an expert in a wide variety of black box testing methods, including performance testing, stress testing, volume testing, and other methods of a similar kind. Which software testing technologies are most suitable for this particular situation? It is required that a summary of at least two software testing tools that are used for software performance testing be provided.Software is sometimes associated with faults, yet the aerospace sector has produced incredibly dependable software for aircraft. What steps are taken, and how are they taken, to guarantee the production of error-free software?Define the Pareto principle, and discuss how it applies to prioritizing system requirements.
- A safety-critical system is one whose failure or misuse may cause human injury or death. Given that an EHR system can be considered to be such a system, which tasks associated with software implementation deserve special attention?Computer Science Lab 3: Goal-Question-Metric (GQM) – Part 1/2 Scenario: Suppose you are software project manager in a reputable organization. You are managing a software development project. “Reliability” is amajor concern for that project. During the testing phase, the testing team has found a series of anomalies (bugs/errors/faults/problems). If the same situation persists for long time (before deadline) the software could not be delivered and would not be of a good quality. You then decideto fix those anomalies before the deadline. Task: ========================================== Draw a GQM tree that will help you to decide when to ship the software. ========================================== Hint 1: Revisit the definition of reliability from slides of first week. Re-read GQM if required. Hint 2: It would be easier to first write Goal, then Questions and then Metrics. Then, think, discuss (with class fellows and with the lab teacher), and update them. Then construct the GQM tree.You may choose any system in your life. However, it may be best to start out with a simple system at a very low level of complexity. Prompt For this assignment, complete the following: Choose a system in your own life. In one paragraph, describe the purpose of this system and describe how it meets the definition of a system. For your chosen system: identify its parts, define their relationships to each other, and describe any feedback loops present in the system. Using Microsoft Visio, construct a model of this system.
