What is the main purpose of verification in the software development process?
What is the main purpose of verification in the software development process?
- To ensure the software development team is properly trained
- To identify potential future users of the software
- To increase the overall cost of development
- To reduce the risk of software failure (correct)
Which of the following is a disadvantage of the waterfall model?
Which of the following is a disadvantage of the waterfall model?
- It allows for early delivery of working software.
- Requirements cannot be changed easily once the phase is completed. (correct)
- It is easy to manage for large teams.
- Testing occurs at the beginning of the software development process.
Why is the maintenance phase important in the software lifecycle?
Why is the maintenance phase important in the software lifecycle?
- To ensure that software defects are never discovered.
- To reduce the overall development time.
- To address problems that arise after the software is in use. (correct)
- To allow for the implementation of new features immediately.

Study Notes
HCI Reporting Waterfall Model
- The Waterfall Model is a sequential approach to software development.
- It's a linear process where each phase depends on the successful completion of the previous one.
- The phases proceed in order, and it's not possible to go back to a previous phase once it's completed.
- The phases are distinct and should not overlap.
Lesson Objectives
- Understanding the Phases of the Waterfall Model: Students will be able to identify and describe each phase, including requirements analysis, system design, implementation, testing, deployment, and maintenance.
- Explaining Sequential Process: Students should understand why the Waterfall Model follows a strictly sequential process and how each phase heavily depends on the thorough completion of the previous phase to ensure project success
- Applying Knowledge in Real-World Scenarios: Students will be able to analyze case studies or hypothetical scenarios to determine whether the Waterfall Model is an appropriate methodology for specific software development projects.
Topics
- What is Waterfall Model: A popular method for software development, Waterfall Model is a linear and sequential process.
- Phases of Waterfall Model: The steps in the model are sequential, including Requirements Analysis, Design, Implementation, Verification, and Maintenance.
- Advantages of Waterfall Model: Simple and easy to understand, beneficial for small projects, easy to manage, and the end goal is determined early. Each phase explained well, and structured approach.
- Disadvantages of Waterfall Model: Requires complete and accurate requirements at the outset, working software is not available for a long time, changes are difficult and expensive, and risk is not assessed until late in the process.
Phases
- Requirements Analysis: The first step, gathering and documenting system requirements from clients.
- Design: Creating the blueprint for the software, ensuring no problems during later phases.
- Implementation: Installing hardware, software, and programs, implementing the database design, testing, coding, and debugging the process; the longest phase
- Verification: Testing and evaluating the software to ensure that it meets the requirements.
- Maintenance: Taking care of finished software to address problems that arise after launch.
