To create high-quality software, you need a process in place that helps you manage your time and resources. That's where the software development life cycle (SDLC) comes in. SDLC is a methodology that helps developers plan, create, test, and deploy high-quality software products at the lowest costs and as quickly as possible. You can use this software quality management process for both small-scale projects and large-scale enterprise applications.There are many different SDLC models out there, but they all feature similar steps: planning, creating, testing, deploying, and monitoring. In the next section, we'll discuss these steps in more detail.
The SDLC methodology involves five phases:
1. Planning: Developers determine the goals and objectives of their projects. They also create a timeline for their work and establish what resources they will need.
2. Creating: Developers start coding the software. This is where they put their plans into action and start working towards their goal while all following the same blueprint.
3. Testing: Developers test their code—running several tests that uncover code quality, integration capabilities, and performance—to ensure the software works as intended. They also perform value stream management platform OpenText™ ValueEdge.
The application life cycle management methodology is important because it helps developers create high-quality software products and provides a foundational framework for all project activities. When following the SDLC methodology, all project stakeholders gain visibility into the project from start to finish. It also helps developers manage their time and resources more efficiently and provides simplified project tracking.
SDLC is a necessary part of any software development project, as it can help your organization build high-performance products. The software development life cycle adds value in the following ways:
If you're still on the fence about implementing an SDLC for your upcoming software development project, here are some benefits that the framework can provide:
SDLC provides one of the highest levels of software project management, control, and documentation. At its core, SDLC ensures all developers and stakeholders have a firm grasp on the project’s “why” and the direction they must follow to arrive at their unified goal.
It's important to note that the software development life cycle is not the same as project management. SDLC is a framework for developing software, while project management is a process for managing all aspects of a project.
Project managers use tools like Gantt charts and task lists to track milestones and deadlines. They also work with developers to ensure that projects are on track and within budget.
While SDLC and project management are two different concepts, they often work together. In fact, many project managers use SDLC as a guide for managing their projects.
There are many ways to implement SDLC into your project. The most common models are:
While there are multiple SDLC models (waterfall, agile, iterative, etc.), many companies have, or are transitioning to, a DevOps model. When security is integrated as part of this process, it is referred to as DevSecOps, Secure DevOps, or sometimes as the Secure Software Development Lifecycle (SSDLC). In the SSDLC, security processes are implemented in all stages of the development life cycle. This is widely accepted as a security best practice to improve resilience to cyberattacks.
If you pay attention to the latest headlines, you’ll see how cyberthreats are wreaking havoc on businesses across the globe. And while software security is becoming a higher priority, for many businesses it’s still an afterthought.
This need for greater software security comes at a time when there is tremendous pressure on developers to build better applications faster than ever and modernize those apps faster, too.. As a result, development teams are turning to more agile processes to further streamline workflows and reduce time to market. This is a big reason why companies are implementing a DevSecOps approach that looks at the entire SDLC and integrates security testing from beginning to end.
DevSecOps enables seamless application security earlier in the software development life cycle, rather than at the end when vulnerability findings that require mitigation are more difficult and costly to implement. Having this DevSecOps mindset means more secure development, security testing, and continuous monitoring and protection in the CI/CD pipeline.
Because the goal of DevSecOps is to make security part of the software development workflow, this means everyone is involved in ensuring that applications are secure, not just the AppSec team. This means implementing secure coding best practices and testing automation, rather than “bolting it on” at the end of the life cycle. This is commonly referred to as “shifting security left” or simply “shift left.”
The idea of shifting security left in the SDLC upends the traditional notion of how, when, and where security controls can be integrated into software development. “Shift left” means finding ways for these formerly siloed groups to work together to develop rapid, but also secure, code releases.
Best practices for shifting security left in the SDLC include:
Leverage both SAST and DAST to get the advantages of both kinds of testing.
Fortify offers a complete toolset of application security solutions to shift security left in your SDLC. By design, Fortify and other OpenText tools bridge the gap between existing and emerging technologies—which means you can innovate faster, with less risk, in the race to digital transformation.
Searching for an SDLC platform than can streamline development? OpenText ValueEdge can help improve the software development life cycle in several ways.
At its core, ValueEdge provides a central repository for all project information. This includes requirements, code changes, and test cases. This single-pane-of-glass approach helps ensure that everyone is on the same page and that all project information is easily accessible.
ValueEdge also leverages test management and traceability to spot key issues during the SDLC process and create better products
In addition, ValueEdge offers reporting and analytics features that can help improve project visibility. These features allow key project stakeholders to see which areas of the project are on track and which areas need improvement.
The software development life cycle is an important process for any software development project. It helps developers create high-quality products, manage their time and resources, and track their progress more accurately.If you want to improve the quality of your software products, using OpenText ValueEdge is the first step.
