FREE Software Engineering MCQ Questions and Answers
Which of the following characteristics doesn't make for a strong Software Requirements Specification (SRS)?
Ambiguity: Requirements should be clear and unambiguous. Ambiguity in requirements can lead to confusion, misunderstandings, and ultimately, errors in the software.
This paradigm was proposed by D. L. Parnas. A small subset of the entire system that was nonetheless a useful system had to be created and delivered to the customer. Through the entire life cycle, the procedure will iterate once more in little steps. Giving the customer a functional system as soon as possible and working increments are two benefits.
The Incremental Model is a software development approach where a large system is broken down into smaller, manageable modules or increments that are developed and delivered over multiple iterations.
Who is in charge of writing code who is proficient in one or more programming languages (such Java, C++, etc.)? It is his responsibility to interpret programming specifications, which are often produced by the systems analyst, and convert them into computer code.
A programmer is a professional who is responsible for writing code to create software applications. They are skilled in one or more programming languages and are tasked with translating the design and specifications of a software system into actual program code that a computer can execute.
Requirements should only state "what," not "how."
Yes, it is a best practice in requirement engineering to specify "what" the system should do rather than "how" it should do it. This is known as the principle of separation of concerns, where the requirements focus on the "what" and leave the "how" to the design and implementation phases of the software development life cycle.
The "what" and not the "how" in requirements is a best practice in requirement engineering. It allows for a more flexible and effective development process by providing a clear understanding of the stakeholders' needs without limiting the design and implementation options available to the development team.
One of the fundamental XP principles that guarantees all production code is created by two programmers at the same machine or site. This is a revision stage that has gone above and beyond. At least one other person always reviews every piece of code.
The practice you're describing is known as "Pair Programming," which is a key practice in Extreme Programming (XP), an Agile software development methodology.
Pair programming involves two programmers working together at the same computer, collaborating in real time to write code. One programmer, called the "driver," writes the code, while the other programmer, called the "navigator" or "observer," reviews the code as it's being written, suggesting improvements, catching errors, and helping to design and think through the code.
Requirement engineering frequently involves competing requirements, with each client arguing that their version is the correct version.
Conflicting requirements are a common challenge in requirement engineering. This is because different stakeholders often have different needs, priorities, and perspectives, which can lead to conflicting requirements. In this situation, it is important to manage these conflicts effectively to ensure that the final solution meets the needs of all stakeholders.
To manage conflicting requirements, it is important to have a clear understanding of the requirements and the stakeholders involved. This can be achieved through a requirements elicitation process that involves gathering and analyzing information from all stakeholders. It is also important to establish a prioritization process to identify the most critical requirements and ensure that they are addressed first.
The Software Requirement Specifications Document (SRS) is written by?
The Software Requirement Specification (SRS) document is typically written by a business analyst, a systems analyst, or a software engineer. These professionals work closely with the stakeholders, including customers, users, and other stakeholders to gather, analyze, and document the requirements for the software.
A system engineer collaborates with the _________ to comprehend system needs.
Stakeholders and users of the system. They then use this information to design, implement, test, and maintain the system, ensuring that it meets the requirements and performs as expected.
As part of their role, a system engineer collaborates with other members of the development team, such as software engineers, hardware engineers, and quality assurance professionals. They may also work closely with project managers to ensure that the system is delivered on time and within budget.
Which of the following describes interactions in use case descriptions?
In use case descriptions, a Product (or System) refers to the software or system that is being developed or documented. The Product can be any software application, web-based system, or hardware device that is being designed to solve a specific problem or provide specific functionality.
The Actor, on the other hand, refers to the user or entity that interacts with the Product to achieve a specific goal or task. Actors can be either human or non-human entities, such as other software systems or hardware devices.
Defining the actors and their interactions with the Product is an important part of creating a use case description, as it helps to ensure that the system is being developed to meet the needs of its intended users.
A phase of the software life cycle during which the interfaces between the system's component pieces are specified.
Interface design is indeed a critical activity within the software development life cycle, specifically during the design phase. It involves the process of specifying how different components or parts of a software system will interact and communicate with each other.
An activity in the software life cycle that involves instructing users on how to use the program.
Training is indeed a significant activity in the software development life cycle that involves educating users, stakeholders, and relevant personnel on how to effectively use the software. The training phase ensures that the individuals who will interact with the software have the knowledge and skills needed to utilize its features and capabilities efficiently.
A group of software development approaches that create software quickly and allow for more design or change.
Agile processes refer to a family of software development methodologies that emphasize flexibility, collaboration, customer feedback, and iterative development. These methodologies aim to address the limitations of traditional, rigid software development approaches by allowing teams to respond to changes and deliver valuable software more frequently.
What are some illustrations of deliverable documents?
"Statement of Work," "User Manual," and "Defect Report" are indeed examples of deliverable documents in the context of software development projects. These documents are created and provided as part of the project to communicate information, guide processes, and ensure the successful completion of the project.
What is the purpose of the software development life cycle's requirements analysis and specifications phase?
The goal of the requirements analysis and specifications phase of the software development life cycle is to understand and document the requirements for the software being developed. This includes gathering and analyzing information about the software's intended purpose, functionality, performance, and other characteristics that are critical to meeting the needs of its users.
Barry Boehm proposed this additional evolutionary method of software development. The software project moves incrementally through the four quadrants of this model, which contains four sections.
The Spiral Model is indeed an iterative and risk-driven approach to software development that was proposed by Barry Boehm. It's designed to address the challenges of uncertainty and risk that can arise in complex software projects. The model involves a series of iterations called spirals, where each spiral represents a cycle of planning, designing, building, and evaluating the software.
