SIT773 SOFTWARE REQUIREMENTS AND ANALYSIS
Waterfall model
Advantages are:
 Easy and simple to use
 Phases are mainly processed and then completed one at a time
 Clearly described stages
 Simplified arranging of tasks (Alshamrani and Bahattab 2015)
 Processes and the results are not well documented
The disadvantages of this particular model are:
 There is no generation of software until late in the life cycle
 Significantly high risk and high uncertainty
 Progress measurement within the stages is not easy
 Cannot accommodate the altering requirements
 The adjustment of the scope during life cycle could lead to the end of project
Parallel development model
The main characteristics of the parallel development are:
 Release preparation
 Tailored or even customer specific software
 Post-release maintenance
 Distribution of the work by various development individuals or teams
 Segregation of the work on various features
 Deployment of various software variants within various environments
Main advantages of the parallel development model are:

 Ability of changing or introducing the requirements during the complete
process
 Less personnel number
 Minimisation of cost
 Increases the speed
Disadvantages of this model are:
 Managerial role is reduced
 Difficulty in software development with the help of just documentation
Iterative life cycle
The advantages are:
 Implemented during early stages (Chi et al. 2019)
 Allows teams with discovering functional or design associated flaws
The disadvantages are:
 Requirement of more resources
 Not suitable for smaller projects
Evolutionary prototyping
The advantages are:
 Useful for the explanatory programming
 Development could be stopped after several iterations
The disadvantages are:
 Inability of setting any time frame
 Difficult to monitor project

Throw-away prototyping
The main advantages are:
 Saves money and time
 Promotes consistency
The disadvantages are:
 Creates confusion due to prototypes
 Excessive time for development
Agile development
The main advantages are:
 Increases customer satisfaction
 Frequent delivery of working software
The main disadvantages are:
 Lack of emphasis on important designing
