Software Engineering 2
Software Engineering II covers a range of advanced topics in software engineering. The first part of the module focuses on software quality. It covers several key quality related issues, including software reliability, dependability, safety and security. The module also builds on the topic of risk management and mitigation previously introduced in Software Engineering I. The second part of the module focuses on several key topics in modern software engineering, including component-based software development, distributed systems engineering, service-oriented software engineering, and software documentation. At the end of the module, students will be able to understand the broader landscape of the discipline of software engineering, and be able to apply advanced techniques and theory to their software development activity.

| FALSE | For systems with a short life, maintenance costs may be several times development costs. | |
| Improvement identification | Identify quality, cost or schedule bottlenecks | |
| System failure | An event that occurs at some point in time when the system does not deliver a service as expected by its users. | |
| TRUE | A poorly designed interface can cause a user to make catastrophic errors. | |

| Customized, Bespoke | These are developed software for a single customer according to their specification (select all that applies) | |
| Software Engineers | They are I.T. practitioners who adopt a systematic and organised approach to their work and use appropriate tools and techniques depending on the problem to be solved, the development constraints and the resources available. | |
| Process change introduction | Modify the process to remove identified bottlenecks | |
| Availability | The ability of the system to deliver services when requested. | |
| TRUE | Dependability costs tend to increase exponentially as increasing levels of dependability are required. | |
| recoverability | It is a UI design principle that allows user to recover from errors. | |
| Software Engineer | It is focused on cost effective software development. | |
| TRUE | Because of very high costs of dependability achievement, it may be more cost effective to accept untrustworthy systems and pay for failure costs. | |
| None among the choices | Some of the components of User interface design process. (select all that applies) | |
| The correct answer i | The use of more expensive development techniques and hardware that are required to achieve the higher levels of dependability decreases the cost of dependability of software. | |
| Reliability | The probability of failure-free system operation over a specified time in a given environment for a given purpose. | |
| TRUE | Designers should be aware of people’s physical and mental limitations. | |
| Technical cost | This factor often dominates system costs in a system development | |
| Survivability | It subsumes the notion of resilience - the ability of a system to continue in operation in spite of component failures. | |
| Change tuning | Evolve and improve process improvements | |
| Specification | Part of the generic activity of software development which checks what the system should do and its development constraints. | |
| Software Engineering | It is concerned with theories, methods and tools for professional software development | |
| Process change training | Train staff involved in new process proposals | |
| FALSE | The use of more expensive development techniques and hardware that are required to achieve the higher levels of dependability decreases the cost of dependability of software. | |
| Reliability | The ability of the system to deliver services as specified. | |
| System error | Erroneous system behavior where the behavior of the system does not conform to its specification. | |
| Software Engineering | It is focused on cost effective software development. | |
| Validation | The process of checking that the software is what the customer wants. | |
| System fault | An incorrect system state i .e . a system state that is unexpected by the designers of the system. | |
| FALSE | The increased testing and system validation that is required to convince the system client that the required levels of dependability have been achieved decreases the cost of dependability of software | |
| ISO 9000 | International set of standards for quality management. | |
| Maintainability | A system attribute which is concerned with the ease of repairing the system after a failure has been discovered or changing the system to include new features. | |
