Question

Why is the waterfall model of software engineering the most commonly used method for development of trusted systems?

Answer 1

Advantages of the waterfall model:

1. Uses clear structure

When compared with alternative methodologies, the body of water focuses most on a transparent, outlined set of steps. Its structure is simple each project goes through these steps:
1.Requirement gathering and documentation
2.System design
3.Implementation
4.Testing
5.Delivery/deployment
6.Maintenance
Teams should complete a complete step before moving onto consequent one, thus if there are roadblocks to completion, they’re delivered to lightweight at once. Half-finished comes ar less probably to induce ignored, departure groups with an additional complete, polished project within the finish.

In addition to being clear, the progression of a body of water is intuitive. in contrast to Six letters of the alphabet or start, the body of water doesn't need certifications or specific coaching for project managers or workers. If you visually define the method at the start of exploitation Lucidchart and justify the methodology, team members can jump into the body of the water system while not a steep learning curve speed their progress.

2. Determines the top goal early
One of the shaping steps of a body of water is committing to associate degree final result, goal, or deliverable at the start, and groups ought to avoid deviating from that commitment. for little comes wherever goals ar clear, this step makes your team tuned in to the goal from the start, with less potential for obtaining lost within the details because the project moves forward.

Unlike start, that divides comes up into individual sprints, body of water keeps the main target on the top goal in the slightest degree times. If your team contains a concrete goal with a transparent finish date, the body of water can eliminate the danger of obtaining stalled as you're employed toward that goal.

3. Transfers data well
Waterfall’s approach is very organized, thus it ought to come back as no surprise that the methodology emphasizes a clean transfer of knowledge at every step. once applied during a computer code setting, each new step involves a brand new cluster of individuals, and although which may not be the case at your company, you continue to ought to aim to document data throughout a project’s lifecycle. whether or not you’re passing comes off at every step or expertise sudden personnel changes, body of water prioritizes accessible data thus new additions to the team will arise to hurry quickly if required.



The disadvantages of the waterfall model:
Waterfall could be a revered methodology, but lately, it’s featured criticism for being an associate degree out-of-date model. The methodology’s limitations become additional apparent reckoning on the dimensions, type, and goals of the project it’s guiding. instead of adapting your organization to Waterfall’s tips later, contemplate these limitations to assess whether or not the body of water is appropriate for your team.

1. Makes changes tough
Waterfall is predicated entirely on following a group of steps that keep groups continuously moving forward. The methodology, in its ancient type, leaves nearly no space for sudden changes or revisions. If your team has loyally followed the steps of a body of water nearly to the top of the project then again faces random roadblock that necessitates an amendment in scope or goals, pivoting won’t be straightforward. You’ll have placed a substantial quantity of labor into a project underneath terribly specific, rigid assumptions. A fulminant amendment to the parameters of the project may render a lot of the work you’ve dispensed up to its purpose useless, which might throw off the complete timeline.

If your team’s comes ar unpredictable or involve frequent amendment, contemplate adapting body of water to permit additional space for reflection and revision as you go, instead of simply at the top, to stop wasted time and energy. If you opt to travel this route, tailor a Lucidchart example to your team’s version of the body of water to stay everybody tuned in to a way to use the adjusted method.

2. Excludes the consumer and/or end-user
As an interior method, the body of water methodology focuses little or no on the end-user or consumer attached to a project. Its main purpose has continuously been to assist internal groups move additional expeditiously through the phases of a project, which might work well for the computer code world. However, if you're employed in associate degree business aside from computer code, shoppers usually wish to be concerned throughout a project, adding opinions and instructive what they require because the project moves forward.

If your comes have clear, unchanging goals from the start and you aren’t accountable for change end-users or shoppers through the event method, the body of water can most likely work well for your team. In alternative cases, contemplate associate degree agile methodology to raised anticipate amendment and keep stakeholders au courant through the lifetime of the project. By involving stakeholders, you lower the danger currently requests for amendment throwing off your project deadlines.

3. Delays testing till when completion
Saving the testing section until half of a project is risky, however, the body of water insists that groups wait till step four out of six to check their product. Outside of the computer code business, the testing section may mean showing a brand new web site style to a consumer, A/B testing content, or taking any range of steps to realize empirical knowledge on the viability of the project. At this time, the project has probably taken significant time to finish, thus giant revisions may cause vital delays.

These are the pros and cons of the waterfall model it is easy to build the project based on the waterfall model that's why software engineering most used common method is waterfall model, based on the waterfall model they are developed different types of models. But the waterfall model is the standard method to develop any project.
