As the name suggests, Agile methodology allows for fast project deliveries with more flexible time constraints, often increasing employee productivity and satisfaction. Unsurprisingly, this methodology’s testing is executed concurrently—from the beginning stage throughout the development process. Now the question is, which testing plays an important role in Agile methodology? Here’s what we think matters the most.
The Agile Manifesto is a document that includes key values and principles. It was written by several developers who believe that any software developer should be able to use them as a guide throughout their project. Originally it was titled “Manifesto for Agile Software Development,” and “Agile Alliance.” It’s a must-read for companies undertaking any software development process today. Aside from knowing its origin and ultimate purpose, what are the 4 core principles of Agile methodology? This article outlines the key points of the manifesto.
The software development industry has to keep pace with challenges and new technologies that emerge every year. This is one of the reasons why several agile methodology frameworks were developed.
Agile methods involve a set of methodologies that serve to accelerate software development processes. With its origins dating back to the mid-1990s, Agile’s concept did not take long to be disseminated among specialists, which resulted in the creation of different models that support project management. In this post, we’ll provide you with a list of the top agile methodology frameworks.
Over the past few years, the software development industry has seen a shift in its dynamics. More companies are now moving towards Agile methodologies to match client requirements. Quick releases and iterative fixes have become the new norm, and the Scrum framework is the flagship framework for this environment. Hence, Scrum Masters have become crucial instruments in this comparatively newer development framework. With that said, it is vital to understand how exactly their roles and responsibilities are defined.
Are you a business owner with no idea which SDLC methodology best suits your needs? This uncertainty is fairly common among startups. There are several SDLC methodologies to choose from, and it can take some time to understand each of them. Although it might be time-consuming and tedious, it’s highly crucial for the success of your company.
SDLC methodologies matter because they indicate the software development process a startup should follow. As someone who’s new to the industry, it’s a risk to choose a methodology. Established companies may have the capacity to do trial-and-error methods, but most startups can’t risk funding something without results. Startups need a method that allows them to quickly produce software, and benefit from returns as they continue to make upgrades. So, how should you start? Understanding the different methodologies will put you in a better position to select the best option for your startup.
For lightweight, small-scale programs, manual development is often sufficient to meet necessary deadlines. However, companies often struggle to release a high-quality, glitchless software that follows all the required guidelines, especially within a brief time frame. In these cases, even properly adhering to several SDLC phases might not be enough. But thankfully, some of them can be automated to save time on manual labor.
Here’s what your team should be automating.
Each phase of the SDLC methodology has its own processes and deliverables that feed into the next phase. The entire methodology is divided into seven system development life cycle stages:
- Requirement collection and analysis
- Feasibility or Requirements Analysis
- Design and Prototyping
- Software Development (Coding)
- Software Testing
- Operations and Maintenance
Stage 1: Requirement Collection and AnalysisThe requirement stage is conducted by a senior team member, with additional input from stakeholders, the sales department, and domain experts within the industry. This information is used to conduct a product feasibility study in the operational, technical, and economical areas. During this stage, the team is given a clear picture of the project’s scope, along with its anticipated issues and opportunities.
Stage 2: Feasibility or Requirements AnalysisOnce the requirement stage is complete, it’s time to define and document software needs. This phase is conducted with the help of the Software Requirement Specification (SRS) document that includes everything that must be developed and designed during the project’s life cycle.
The five main types of feasibility checks are:
- Economic: Can the project be completed within the set budget?
- Legal: Does the project comply with cyber laws and other regulations?
- Operation: Can the team create operations outlined by the stakeholder or client?
- Technical: Can the current computer system support the software?
- Schedule: Can the project be completed within the given time frame?
Stage 3: Design and PrototypingIn this phase, the software specifications need to be turned into a design plan or a prototype. The product architects need to create a plan called Design Document Specification (DDS), which the stakeholders have to review and give feedback on. Based on certain parameters, such as risk assessment, budget and time constraints, design modularity, and robustness, the best product design approach is selected.
Three types of design documents are developed at this stage:
- Low-Level Design (LLD): This is a component-level design process based on HLD that follows a step-by-step refinement process. It goes into the separate modules and features for each program.
- High-Level Design (HLD): This is a general system design that consists of a brief description of each module. This indicates the interface relationship and dependencies between them, an outline about their functionality, database tables and complete architecture diagrams.
- Detailed-Level Design (DLD): This is the most detailed technical document. It describes user stories, state transitions, logical sequences, error processing algorithms, and more.
Stage 4: Software Development StageIt’s now time to turn everything into a working code. This is the earliest phase in which the final product starts to take shape. Developers are most involved during this stage. They work alongside the product owner and software testers to ensure everything runs smoothly.
Stage 5: Software Testing
The software testing phase puts testers to work. The testing team will check for code quality to ensure it meets all the requirements for optimal functionality. If they find any bugs, they relay them to the developers, who then fix the bugs and send back the software for re-testing. The process continues until the software works properly.

Stage 6: Installation/DeploymentOnce testing is over, the final deployment process starts. At this stage, the product owners work with the marketing team to produce marketing material and documentation, such as user manuals, guides, and more.
Stage 7: Operations and MaintenanceDuring this phase, the main focus is to ensure that the software continues to meet all requirements and perform as per the specifications that were outlined in the first phase.
The following three activities occur during the maintenance phase:
- Developers watch software for bugs. If they find one, they create a bug report. A sign that everything is working well during this time is when developers can identify and resolve the issue as quickly as possible.
- Developers upgrade the application to the newest version of the software.
- Developers add new features to the existing software to enhance its functionality.
Which SDLC Stage Is the Most Important?Among all system development life cycle stages, have you ever wondered which is the most important? For Bydrec, every single phase is crucial, so nothing should be left out or rushed. All SDLC stages should be valued equally.
However, many software development experts suggest that the requirement collection and analysis stage is the most important aspect of SDLC. This is when the project team begins to understand what the stakeholders expect from the project. The project team must first understand the stakeholder’s needs because this information is critical to developing a software product that meets their expectations and needs.
Software Development Life Cycle Models
Now that you have a better understanding of how SDLC stages work, here are some SDLC models that you can utilize for your project:
With so many project management methodologies to use, you might be wondering if waterfall project management is still relevant in 2020. Since the 70s, this traditional project management has a long track record of success. So, let’s take a closer look.
While scrum is considered a more rigid project development framework, it has many advantages that make it a great option for any project development. It involves all team members, including the project owner, which promotes cohesion and inclusivity in every step of the process. Since every member of the team has a different responsibility, it also allows for faster completion of the project. The systematic approach and strict timelines for development stages also reduces error because it allows team members to identify and solve any problem as soon as it comes up.
There’s always a risk that project management can always go wrong, especially when you don’t utilize the right methodology. Agile project management with Scrum is one of the best options to choose. It promotes efficient teamwork, and helps with faster completion of the project. The concept of Scrum is also more applicable in other areas, aside from software development. This is why it’s considered a framework rather than a methodology. In this article, you’ll learn more about how the scrum process works.
