Chapter 12.3, Problem 1RQ
Program Plan Intro
Waterfall software development process:
- Waterfall model is the first process model in which each phase is completed before starting the next phase.
- It is the first Software Development Life Cycle (SDLC) approach used for developing the software.
- It includes six different types of phases and they are as follows
- Investigation
- The clear understanding of the problems in a system and solving them is performed in investigation phase.
- This helps in developing the project in less time.
- Analysis
- Gathering the data from the existing system and determining the requirements for new systems is done in analysis phase.
- It defines the user requirements and expectations.
- Design
- The existing program or code is executed according to the required design.
- It mainly depends on user requirements.
- Its aim is to convert the user requirements to a complete system.
- Construction
- Construction phase is used to execute the code according to design.
- It is managed by the group of programmers or developers called development team.
- Integration and Testing
- In integration and testing phase, the individual programs or codes are integrated together and tested as group.
- It is used for finding the errors and solving them.
- Implementation
- It is the last phase of the project development process in which development of the project is implemented and maintained.
- It includes user preparation, site preparation, installation and many such.
Agile software development process:
- It is an iterative system development approach used for developing the system in terms of sprints.
- It includes the time period from two weeks to two months.
- It includes the communication between users, developers, testers and managers.
- It focuses on the quality of the development of project.
