FREE Software Engineering Questions and Answers
Which of these software engineering processes is not included in software engineering?
Software dependence refers to the extent to which an organization or individual relies on software applications or systems to perform their daily operations or achieve their objectives. It can also refer to the reliance on specific software platforms, languages, or tools to develop, maintain, or deploy software.
Software dependence can have both positive and negative consequences. On the one hand, software can help organizations automate tasks, increase productivity, and improve decision-making. On the other hand, software dependence can also make organizations vulnerable to software failures, security breaches, and vendor lock-in.
Customers receive updates for XP every ______ weeks.
In Extreme Programming (XP), increments are typically delivered in short timeframes called "iterations" rather than "increments." An iteration is a fixed time period during which development tasks are undertaken and completed, resulting in a potentially shippable product increment. The iteration length in XP is usually one to two weeks.
What are the dependability's four dimensions?
Availability, Reliability, Security, and Safety are indeed four key dimensions of dependability in the context of software and systems engineering. These dimensions collectively contribute to the overall dependability of a system, ensuring that it performs as intended and meets the requirements of its users and stakeholders.
The foundation of Agile Software Development is
Agile Software Development is indeed based on both incremental and iterative development approaches.
How many phases does the RAD model have?
The RAD (Rapid Application Development) Model is a software development model that emphasizes rapid prototyping and iterative development. Some of the characteristics of the RAD Model include:
> Iterative development: The RAD Model involves iterative development cycles, where a functional prototype is built and refined in a series of short iterations.
> Rapid prototyping: The RAD Model emphasizes rapid prototyping, where a simplified version of the software system is built quickly to gather feedback and refine requirements.
> Incremental development: The RAD Model is an incremental development model, where each iteration builds on the previous iteration, with additional functionality and features added in each subsequent cycle.
> User involvement: The RAD Model emphasizes active user involvement in the development process, with regular feedback and collaboration between the development team and the users.
> Time-boxed development: The RAD Model involves time-boxed development cycles, with strict time limits for each iteration to ensure rapid development and delivery of working software.
What among the following is not a part of SRS?
Design solutions are not included in the Software Requirements Specification (SRS).
The SRS is a document that describes what the software should do and what it needs to accomplish, from a user's perspective. It serves as a communication tool between the software development team and the stakeholders who need the software.
The SRS should not include information on how the software will be designed or implemented, as these details come later in the software development process. Instead, the SRS should focus on the functional and non-functional requirements, constraints, and assumptions of the software system.
Which of the following characteristics does a good Software Requirements Specification (SRS) not have?
These levels represent a maturity framework that organizations can use to assess and improve their software development processes. The goal is to progress from lower levels of maturity to higher levels, as organizations become more disciplined, consistent, and capable of producing high-quality software efficiently.
The foundation of Agile Software Development is
In Agile Software Development, these two approaches are combined to create a flexible and adaptable development process that emphasizes delivering value to the customer early and often, while also allowing for ongoing feedback and improvement. The team works in short cycles, developing and delivering functional increments of the software, while also iterating on the design, development, and testing processes to continually improve the software and meet the needs of the customer.
In which four framework activities does Extreme Programming (XP) take place?
These four activities are central to the XP methodology and are performed iteratively throughout the development process. The iterative nature of XP allows for frequent feedback and adjustments, leading to the creation of high-quality software that aligns closely with user needs and expectations.
The two dimensions of the spiral model are _____ and ____.
The Spiral Model's unique feature is its emphasis on managing and mitigating project risks through a series of iterations. It allows for more informed decision-making based on feedback, and it adapts to changing requirements and uncertainties. The model provides a systematic approach to managing complexity and risk, making it suitable for projects with evolving or uncertain requirements.
FAST is short for
FAST stands for "Facilitated Application Specification Technique." It is a requirements engineering technique used to gather and define software requirements through collaborative workshops and sessions involving various stakeholders, such as users, developers, and business analysts.
Which of these has no impact on various software categories as a whole?
Flexibility is a characteristic that can indeed affect different types of software, but its impact can vary depending on the specific context and requirements of the software being developed. Flexibility in software refers to the ability of the software to adapt and accommodate changes without major rework or disruptions.
If and only if ________, is the SRS considered consistent?
The Software Requirements Specification (SRS) is considered consistent if and only if there are no conflicting or contradictory requirements specified within it. In other words, the SRS is consistent when all the requirements stated in it are compatible and can be satisfied simultaneously.
Consistency is a critical attribute of an SRS because any inconsistencies or conflicts in the requirements can lead to errors, misunderstandings, and project delays. If requirements conflict with each other, it may be impossible to satisfy all of them, and trade-offs may need to be made.
Which two models' components were combined to create the incremental model?
The Linear Model, also known as the Waterfall Model, is a sequential and linear approach to software development, where each phase of the development process (requirements, design, implementation, testing, and maintenance) is completed before moving on to the next phase. This approach does not accommodate changes or feedback well, as each phase must be completed before moving on to the next.
The Prototyping Model is an iterative approach to software development where a preliminary version of the software system is built to gather feedback and refine requirements. The prototype is developed in a cyclic and iterative manner until the final product is developed. The focus is on early feedback and requirements gathering, rather than completing each phase before moving on to the next.
RUP is an acronym for ______, which was produced by a division of _________.
RUP stands for Rational Unified Process, which was indeed created by Rational Software, a division of IBM. Rational Unified Process is a software development process framework that provides a structured approach to the entire software development life cycle. It offers guidance on how to effectively design, implement, and manage software projects.
In what ways are incremental models and spiral models different?
The main difference between the Incremental Model and Spiral Model is that the Incremental Model is focused on delivering value to the customer through frequent releases and feedback, while the Spiral Model is focused on managing risks and uncertainties in software development projects. The Incremental Model is ideal for projects with well-defined requirements and a clear product vision, while the Spiral Model is ideal for complex projects with high levels of uncertainty and risk. The Incremental Model is generally more flexible and adaptable, while the Spiral Model is more structured and process-driven.
