Software Development Models: 8 Popular SDLC Methodologies
To conduct a software development project, it is impossible not to mention the appropriate software development models for that project and that software product. Since models of the software development life cycle (SDLC) reveals the best routes to take when tackling the challenging task of creating software. The selected model has a significant impact on the project’s quality, timeliness, expense, and capacity to satisfy the objectives.
There are 8 significant software development models that most development teams still evaluate and apply among the many diverse software development models to fit varied aims. Let’s have a look at this post!
1. Agile Software Development Methodology
The word “Agile” has become the industry standard for referring to development processes.
It’s a catch-all word for any approach that follows a development algorithm, values feedback, and prioritizes results above procedure. Compared to the models that we have seen so far, Agile places a lower priority on the collecting of criteria and the recording of processes.
In contrast to more conventional approaches to project organization, the majority of modern software development approaches use an agile approach that places a premium on showing signs of improvement, teamwork, and productivity. It may adjust to unique circumstances and develop in response to fresh input.
Most of the world’s big companies operating in custom software development such as: Groove Technology, Apple, Meta, SCNSoft,… all handle these model applications to develop their projects.
Why and when to utilize it
- Experimental endeavors where prompt comments are essential
- Tasks when criteria cannot be specified in sufficient depth
- Massive, iteratively-developed projects
- Software development circumstances
2. Scrum
Scrum is the most widely used Agile framework, and it relies on time-bound iterations (known as sprints) to complete distinct aspects of a project. The plan is to divide the product into manageable chunks that can be finished in a short amount of time. The team keeps tabs on the progress and future plans while looking for problems and answers.
At the conclusion of a sprint, everyone gets together to present what they’ve accomplished (which usually consists of a working version of the final product). In the same gathering, team members may assess the current state of the process and brainstorm ideas on how to enhance it in the next sprint.
3. Kanban
Instead of using sprints, Kanban relies on a display board called a Kanban Board to organize work. The team spells out their goals, their responsibilities in achieving those goals, and their current status on each assignment in this document. Since the team has clearer visibility into the project’s trajectory, they are better able to identify problems and set priorities.
4. Extreme Programming (XP)
Extreme Programming, often known as XP, is another kind of Agile paradigm that promotes the use of rapid releases within brief iterations of the development process. This may seem severe, and that’s because it is. The very idea of going above and beyond the norms of conventional software engineering is what gives XP its moniker.
5. Waterfall Model
Since it has been around for a while, Waterfall is one of the most well-known SDLC models. In the waterfall model, each step is shown as a discrete operation that must be finished before the next may begin. To put it another way, you can’t go on to the next step until the current one is finished.
None of the processes in this paradigm cross over into one another. The Waterfall methodology is very organized. This implies that the team must complete a predetermined set of tasks and produce a certain set of paperwork at each stage before moving to the next one.
Why and when to utilize it
- Procedural complexity is low, and the scope is limited.
- Initiatives with rigid specifications
- Jobs that must stick to strict timetables and set budgets
- Extremely constrained endeavors
Taking such a method of development ensures a very predictable timetable and budget, but it can’t be adapted to meet any unexpected needs that may arise throughout the process.
It’s also quite expensive to remedy any problems discovered by engineers during testing since by that point the solution is almost complete.
6. Spiral Model
The software development process followed by this methodology is risk-based.
That implies the risks associated with a project are the primary factor in shaping the Spiral model. This paradigm draws from a variety of other methodologies, including incremental development, waterfall, and component is added, to accomplish its goals.
Using the Spiral approach, you’ll do four main things: prepare for risks, analyze those risks, build prototypes, and assess the results. Accordingly, the work begins out with a risk assessment that sets the tone for the team’s approach. The team reviews the first cycle of the project when it is finished in order to make changes for the following iteration.
Why and when to utilize it
- Misguided projects that don’t have defined needs
- Unique endeavors with extensive needs
- Extensive endeavors
- Investigations into potential new products
7. The V Model
The V-shape formed by the early decline and ability to bounce back serves as the inspiration for the model’s moniker. One way that the waterfall model may be expanded upon is via the V Model, which focuses on validation and testing. Although this improves the product as a whole, it extends development time and raises costs.
As the V diagram shows, the evolution of these two clauses is similar. The approach is called the Verification and Validation model because for every step in the authentication process, there is an identical step in the validation phase. In addition, the V-model is inflexible since requirements are collected up front and cannot be modified during implementation.
Why and when to utilize it
- Those initiatives that are both sophisticated and high-stakes need to have the highest levels of reliability and performance
8. Lean Software Development Approach
There is a direct line between lean production and operational software development.
Lean development, at its heart, is predicated on the tenet that wasteful processes should be purged. Employee productivity may be maximized if time spent on menial duties is cut down.
Using the five tenets of lean management, groups may streamline their efforts to eliminate inefficiency and enhance efficiency. Lean is both a collection of practices and a way of thinking that may improve how we do our jobs. Agile and alternative approaches to developing software may benefit from the lean tenets and concepts. The principles of lean development may be easily applied to the task of expanding agile techniques across big or expanding enterprises.
Why and when to utilize it
- To develop an item that communicates with an external API
- Participants in the lean process are encouraged to show of hands
