29 Questions
What is the main purpose of system prototyping?
To check the customer's requirements and the feasibility of some design decisions
How does incremental delivery support change avoidance and change tolerance?
It reduces the cost of incorporating changes into later increments
What is the main purpose of a software prototype?
All of the above
What is the key characteristic of the rapid, iterative development of a prototype?
It allows system stakeholders to experiment with the prototype early in the software process
How can a software prototype help anticipate changes that may be required?
By allowing for experimentation with the system early in the software process
Which of the following is a key benefit of incremental delivery?
It avoids the premature commitment to requirements for the whole system
What is the first step in the component analysis process?
Analyzing the requirements specification
What happens if no existing components can be found to reuse?
New software is developed from scratch
What is a potential disadvantage of component analysis?
Compromises in meeting user requirements
What is the purpose of the system design step in component analysis?
To create a framework for integrating the components
What happens if the available components do not provide all the required functionality?
Additional software may need to be developed
What is a potential advantage of component analysis?
Reduced amount of software to be developed
What is the primary focus of a prototype in software development?
To focus on areas of the product that are not well-understood
What is the primary challenge with incremental development of large, complex systems?
All of the above
Which of the following is a reason why prototypes should be discarded after development?
Prototypes are normally undocumented and may not meet quality standards
What is the key focus of the reuse-oriented software engineering approach?
Integrating existing reusable components into a system
What is the primary advantage of incremental delivery in software development?
It delivers part of the required functionality in increments
Which of the following is NOT considered a type of software component that may be used in a reuse-oriented process?
Custom-built software systems developed from scratch
What is a key characteristic of COTS (commercial off-the-shelf) systems?
They are stand-alone software systems that are configured for use in a particular environment
In incremental development, how are user requirements handled?
User requirements are prioritized, with highest priority in early increments
What is a potential problem with using prototypes in software development?
It is difficult to estimate the number of iterations required
Which of the following is NOT a type of software component mentioned in the passage?
Libraries of functions
What happens as new increments are delivered in incremental development?
The new increment is integrated with existing increments
What type of process is the waterfall model?
Plan-driven process
What is the result of each phase in the waterfall model?
One or more approved documents
When are problems identified in the waterfall model?
During the design phase
What is a key advantage of the waterfall model?
Visibility of the process for managers
What is a key disadvantage of the waterfall model?
All of the above
When should the waterfall model be used?
When the requirements are well-understood and unlikely to change
Test your knowledge on the plan-driven Waterfall model in software engineering. Understand the importance of planning, scheduling, and documenting activities in each phase before proceeding to the next. Identify how design problems are addressed and resolved throughout the development process.
