- It is not possible to estimate the size of the project
- A certain number of selected functions have been planned, but it is not known which will prove useful and which will be removed
- There is no accurate documentation.
- High probability of sudden significant changes in the project during the implementation process.
- Our task is to implement in accordance with the established documentation that will be developed on the basis of the presented concept, idea.
ADVANTAGES
DISADVANTAGES
ADVANTAGES

- There is a list of functionalities and screens that will be implemented in the project
- No modifications will be made to any of the application modules during implementation
- It’s known how big the potential user base will be
