Test Planning: Test Planning in STLC is a phase where a senior QA Manager plans the test strategy. Here the resources, test environment, test schedule, and test limitations are determined.
Test Case Development: In the Test Case Development phase, the testing team noted the details of the test cases. The testing team also prepared the test data in this phase.
Test Environment Setup: Test Environment Setup is a phase where the hardware and software criteria are decided in which a software product or application is to be tested. It is an important aspect of STLC.
Test Execution: In the test execution phase, the testing team starts executing test cases based on test case development and test environment setup.
Once the testing phase is completed, the software application or product is deployed in a production environment or UAT (User Acceptance Testing), depending upon the customer’s requirements. Sometimes the deployment happens in stages as per the business strategy of a software development company.
Every software company has its own process for software deployment. But overall, software deployment can be determined in three phases: preparation, testing, and deployment.
Preparation: In the preparation stage, software developers gather all the code, functions, libraries, files, and resources needed for the software application to function. Together these items are packaged as a single software release.
Deployment: Once the software is fully tested, it is pushed to a live environment. Software developers may run a set of scripts to update relevant databases before the software goes live. The final step is to check for errors and bugs on the live server.
After the deployment of software into the production environment, maintenance and updates of the product are done. If issues come up and needs fixing or enhancements, they are taken care of by the software developers.
Adaptive Maintenance: Adaptive Maintenance in an application or software is done when a customer wants it to run on a new platform or operating system with new hardware or software.
Software Update is a way for a software developer to make changes and fine-tune the software to make it the best it can be. Software Updates have frequent small improvements instead of any major changes. Software Updates sometimes run automatically as a background process and sometimes come in a downloadable form. Software Update is necessary for a product or application to be running successfully.
Software development companies and software developers follow SDLC models in their software development process to manage a project efficiently. SDLC Models are also known as Software Development Methodologies.
Depending upon the project requirements, software developers choose a specific SDLC Model and stick to it through the entire Software Development Life Cycle. Each software development methodology (SDLC Model) has its strengths and weaknesses, and each SDLC Model exists for a specific reason.
Each SDLC Model or Software Development Methodology follows a series of unique steps, and all of them ensure software development success. Here is an overview of the most commonly used SDLC Models (Software Development Methodologies) in software development.
The Waterfall Model is one of the oldest and universally accepted SDLC models. It is also known as Linear Sequential Life Cycle Model. It is one of the simplest and easiest models to use.
In the waterfall model, each phase must be completed before moving to the next one. Overlapping of phases is not possible in the waterfall model. It was the earliest SDLC approach used for software development.
In the waterfall model, the outcome of one phase acts as an input to the next phase. The sequence of phases in the waterfall model is:
Agile Methodology is a software development practice that promotes continuous iteration of development and testing in the software development life cycle. In agile methodology, the entire software development project is divided into small incremental builds. Each iteration lasts from one to three weeks depending on the development project.
DevOps is a software development methodology that combines the approach of Software Development (Dev) and IT operations (Ops) participating in an SDLC. DevOps is a software development methodology and a set of practices that support an organization’s culture.
Software Development Company In BangladeshDevOps enhances the collaboration between the different departments of a software development organization. It also collaborates with SDLC phases such as development, operations, and quality assurance. The ultimate goal of DevOps is to decrease the duration of SDLC while delivering the features, updates, and fixes frequently.
RAD or Rapid Application Development is an SDLC model that focuses on high-quality software development with low investment costs. The RAD model allows software developers to adjust according to the project’s requirements quickly. The ability to adjust in a constantly changing market results in low investment costs.
Scrum Methodology or generally known as Scrum, divides the software development project into smaller modules. Each module then works with an independent strategy. Like Agile Methodology, Scrum Methodology is also a popular software development methodology. Software development with Scrum Model is done rapidly as it allows a series of iterations in a single go.
Spiral Model is an SDLC model that provides support for risk handling. Spiral Model helps to group and adopt one or more process models. The spiral starts with the smaller aspect of software development and then moves to the larger aspects of the project. Risks at each step are first handled, and then only the next iteration is taken.
Lean Methodology or Lean Model focuses on optimizing time and resources and creating easily changeable software. The goal of Lean Methodology is to build software in less time and at lesser costs. An MVP (Minimum Viable Product) is released in the market and based on the user feedback, other functionalities are added.
Kanban Methodology is a lean software development methodology that focuses on work in progress and just-in-time delivery. This SDLC model allows software development companies to start with their existing workflow and drive evolutionary changes.
In the software development process, the kanban methodology aims to manage the flow of features so that the number of features entering the process remains the same as those being completed.

An Incremental Model is basically a series of waterfall cycles. The requirements are divided into the group at the start of SDLC. For each group, the SDLC model is followed. The software development life cycle is repeated until all the requirements are met.
In the incremental model, each SDLC acts as the maintenance phase for previous software releases. Any modifications and changes in software allow development cycles to overlap.
The prototype model is a software development model in which a prototype is built, tested, and reworked until the requirements are met. It is created by keeping the end product or software in mind.
The prototype model is best suited when the requirements are still not precise. It is basically a trial-and-error method that takes place between software developers and clients.
In simple words, Software Outsourcing or Software Development Outsourcing describes a situation where an organization chooses to hire a software development team to carry out software development tasks. Software Outsourcing is the practice of handing over the control of specific business projects and responsibilities to a third-party vendor that is qualified and capable of handling them.
According to research, the IT sector is the most outsourced field of all. By the end of 2022, IT outsourcing is expected to reach USD 261.9 billion. Software outsourcing is indeed playing a vital role in the growth of the IT sector. And, such robust statistics clearly define that the software development market is on the rise for at least the next few decades. Another study revealed that Software Application Development is the most outsourced IT functions worldwide.
There are multiple ways for an organization to outsource its software development project to software development companies across the globe. These software development companies can be on-shore, off-shore, or near-shore.
The advantage of onshore software development is that there are no time zone and language barriers. It makes communication easier and outsourcing more effective. However, the outsourcing cost can be one of the disadvantages.
This is the most used outsourcing type of all. The main advantage of this is cost-effectiveness due to low labor costs. Besides, the availability of the latest tools like Zoom, Google Meet, and Slack helps in effective remote management of software development.
