Many application development methodologies have been developed over the years.
Which methodology works best in the support of E-Business solutions?

A.
Standard

B.
Iterative

C.
Waterfall

D.
Thin-to-fat

Explanation:

Compared with the traditional waterfall process,the iterative process has many advantages.

1. Serious misunderstandings are made evident earlyin the lifecycle, when it’s possible to react
to them.
2. It enables and encourages user feedback, so as to elicit the system’s real requirements.
3. The development team is forced to focus on those issues that are most critical to the project,
and team members are shielded from those issues that distract them from the project’s real risks.
4. Continuous, iterative testing enables an objective assessment of the project’s status.
5. Inconsistencies among requirements, designs, and implementations are detected early.
6. The workload of the team, especially the testing team, is spread out more evenly throughout
the lifecycle.
7. This approach enables the team to leverage lessons learned, and therefore to continuously

improve the process.
8. Stakeholders in the project canbe given concrete evidence ofthe project’s status throughout
the lifecycle.
Note:
Waterfall model of the software development process was derived from other engineering
disciplines. It was initially adopted by software engineers as a method of making the
development process more visible. It is termed the waterfall model because one stage cascades to
the next. Each of the process activities involved are seen as separate. As each stage is completed
it is signed-off and development progresses to the next stage
