Waterfall strengths and weaknesses for software development

One of the most famous and widely used approaches to software development is the waterfall model. Access to the waterfall is an old technique that has been in use for a long time, but in the modern times the agile approach is becoming more and more prominent.

The waterfall approach, as seen from the name, refers to a systematic approach, different. Otherwise you can not go. The process works like the effect of a horizontal flow of water that runs in one direction which goes downhill.

In this process, the life cycle of the development process is predetermined. All steps are determined before the project starts. The approach is predictable, where the team knows the order of the individual steps and works accordingly. It starts from the requirement analysis, from the design phase, and continues between the implementation, testing and maintenance stages.

The waterfall approach can be very useful to those who are aware of their requirements. The planned approach works for them because they want fixed processes and budgets. If fixed processes are advantageous, they may sometimes be unpleasant. In cases where the client does not clarify the requirements and findings in the project to change this approach, this approach may prove to be quite problematic

Another point of the approach to waterfalls is that the requirement for the construction and analysis of architectural structure takes time. Wide-ranging research begins as the following sections are entirely dependent on the design strategy. However, the good thing is that everything is thoroughly worked out and all aspects have been studied in advance. Developers in such cases know what they expect from them.

The waterfall approach operates in a systematic order, one step after another, and ends at the end of the testing phase. If there are major problems during the test phase, it will be a long process of modification to make the changes. The process can consume more time and money.

We can not conclude that one approach is better than the other, because each method would have its own strengths and weaknesses. Determining the success of each method depends on how it is used and whether the approach meets the scope of the work to be implemented. While a particular approach may be suitable for a particular project, it may be completely unnecessary under other circumstances. For example, some argue that agile methods are not suitable for offshore development because they require closer links and communication, which is not possible in an offshore project.
