1) waterfall models
Making the waterfall model of software starts with project
feasibility analysis, requirements analysis and planning process Then proceed
with the design and coding followed code.setelah finished typing test was done
and when the program has passed the test of the installation program is done
and thereafter the maintenance phase .
The workmanship in every late-stage software required
workers who have been certified to guarantee the results of each stage.
waterfall model
of relatively simple model and easy to do, but this model also has some
disadvantages such as:
- The possible need for a frozen system that causes no
kompatitibel with hardware.
-pembekuan needs of the system has resulted in the problem
specification
hardware.
-situation like this is very dangerous if it happens to run
out of funds at the time of the project.
-it can be triggered the requirement.
-need official documents in the end of each stage.
2) Prototyping
prototytping made to overcome the weaknesses of the
waterfall model.In Prototyping design, coding, and testing, each phase is
done very formally or thoroughly. Protyping stages starting with requirements
analysis, design, code, and test phase of the program requirements system.Dengan
freezing prototyping can be overcome.
3) Iterative Development
Iterative Development merupakann combination of the
waterfall model and prototyping, along with the addition capabily to
the system until the full system is implemented a. on the
development process of iteration is known.
4) Rational Unified Process
This process is also known iteration process. there
are several
phase in this process;
- Inception Phase
- Elaboration Phase
- Construction Phase
- Phase Transitions
5) timeboxing Model
in this model there is a time limit for each stage in the
project.
