As a software developer, I am always interested in learning about different models in software development. Each model has its strengths and weaknesses, and it is important to know the different options available before choosing one for a project. In this blog post, we’ll explore eight popular software development models.
Models in Software Development
The software-development models are the processes or methodologies used to develop a project, depending on its goals and aims. Many Software Development Life Cycle (SDLC) models have been created to meet different objectives. These models describe the phases and the order they are performed.
The model you choose has a significant impact on the testing being done. It will determine the what, where, and when of our testing plans, influence regression testing, and determine which test techniques to use.
There are many models in software development. These are the main ones:
- Waterfall model
- V model
- Incremental Model
- RAD model
- Agile model
- Iterative model
- Spiral model
- Prototype model
Choosing the suitable model for developing your software or app will guide your development, and testing is important.
Companies choose different software development models depending on their product or application. The most popular model is now the Agile Methodology.
The very old model is the Waterfall Model. The Waterfall model’s testing phase occurs only after development is completed. This can result in many bugs being reported at the end of the project, which can be expensive and time-consuming to address.
People are now choosing the ‘Agile model.’ After every sprint, there is a demo-able feature. The customer can then see if the features are fulfilling their needs.
Many companies also use the V_model in their products. V-model is nothing more than ‘Verification and ‘Validation. The V-model maps the life cycles of the tester and the developer. This model allows for testing side-by-side with the development.
Similarly, ‘Incremental model, RAD, and ‘Iterative models’ can be used based on the customer’s requirements and the product’s needs.
Why You Need SDLC Models
Most software development companies have a software development lifecycle (SDLC), which typically includes the following phases of app creation:
- Analysis of requirements.
- Design
- Development and testing.
- Implementation
- Documentation
- Maintenance
These stages of software application development represent the typical process, from initial discovery to launching a full-fledged product with 24/7 customer support. Clients usually want a tailored approach.
There are a bunch of different business models that encompass these stages. They already have their fundamental principles, general flow, and deadlines.
The value of SDLC models lies within process optimization and, as an ending factor, team performance improvement. Each model is unique, and the company should implement it with the same work techniques, vision, mission, tempo, and working methods.
There are many software models to choose from to find the right one for your company. It will also be easy to adapt by your team.
Things to Consider when Selecting a Software Development Model
There are more than 50 different SDLC models available. Each one has the potential to help you achieve your goals or hinder your progress. Software developers know how much time can be lost when mistakes are made. If you choose the wrong software development model, things can get worse.
After all that, it is time to choose which software model you want to use for your project. This will require a lot of thought. When weighing different software models in software engineering, these are the factors you need to think about:
Timeframe: This refers to the time you are assigned to complete the project’s various aspects. How quickly you should produce results, how long you have to finish the project, and whether you can ask for an extension.
Conditions: The terms and conditions of the project.
Project size: The project size, how many people are involved, and its role in the enterprise.
Engineer Skill: How experienced the developers are and how many people they have working on the project.
Project Scope: How will the impact be felt in different industries, how adaptable are the applications, and how scalable?
Objective: This describes the purpose of the project, its features, and potential applications.
Programming language: To determine which programming language will be used for the software project and which parts will be used.
These are the key factors to consider when deciding which type of software development lifecycle model you want.
Software Development Best Practices
Some other useful practices can be used in addition to the stages and models of software development. These can be applied to any part of the development cycle.
Source control
A source control system is a plan to protect your source code. It is a plan that keeps your source code in only one location with secure access and logging.
This could mean a physical space in the office where files and data can be accessed from one place. It could also mean logging in to a cloud-based development platform through an encrypted connection.
In addition, to change management systems, source control tools keep track of who’s working on what and allow you to roll back to previous versions of files. A backup system stores your projects so you won’t lose them if your computer crashes.
Continuous integration(CI)
When developers work on separate components, there’s no guarantee that the individual components will work together. That’s why CI was developed.
Before CI, teams could create their projects. This created significant problems when the developers combined the applications together.
The CI process ensures all development teams use the same programming language and library. This avoids any duplication of code and eliminates any chances of conflicting software.
Management systems
Software development cycle management systems are used to manage and control each stage of the development process. Management Systems provide transparency for each phase and the entire project.
They can also be used to track bugs and manage work. These metrics or KPIs can be used for improving parts of the cycle that aren’t running efficiently.
Conclusion
There are many different models in software development, each with its advantages and disadvantages. The suitable model for a project depends on the specific business goals and needs. However, by understanding the different options available, businesses can make more informed decisions about which model is best for their next software development projects.
