Software Development Lifecycle

The Software Development Life Cycle (SDLC) is a highly efficient process that provides structure from the conception of an idea to its realization. All projects are subject to this 7-step cycle, beginning with imagining a product then culminating in development, with a deployment and maintenance of it.

• Requirement analysis
• Planning
• Software design such as architectural design
• Software development
• Testing
• Deployment
• Maintenance

This phase of the Systems Development Life Cycle involves gathering input from each involved party, like customers, sales personnel, industry experts and coders. Asking "What are the prevailing problems?" allows us to comprehend what works well and what needs improving in our existing system with an eye towards bettering it.

At this juncture of the software development lifecycle, it is essential for the team to uncover what resources and costs are needed to bring any analyzed requirements into fruition. Additionally, there should be a comprehensive assessment of potential risks and precautionary measures in place before beginning. In short—determine if the project is achievable with minimal risk while striving towards success!

Wondering how we will accomplish our desired outcomes? This phase of the SDLC begins by transforming the software specifications into a design plan, known as the Design Specification. Every stakeholder then reviews this strategy and offers constructive feedback or ideas. It is vital to have an approach for accumulating and including stakeholder remarks in this document; otherwise, it could result either in excessive costs at best or total failure of the project at worst!

It's time to create what we have envisioned! Let’s make sure each developer adheres to the blueprint that was agreed upon for this stage. It is imperative that guidelines are set in place regarding coding style and practices, such as a nomenclature system for files or variable naming conventions like camelCase. This will guarantee organized and uniform code production which aids comprehension — but also facilitate testing during later phases of development.

We are now at the stage where we must determine if our expectations have been met. Our Quality Assurance engineers develop a test plan to investigate any defects or shortcomings in order to bring the product into compliance with its original specifications. We employ both manual and automated testing, along with comprehensive reporting tools, so that we can demonstrate definitively whether or not the code meets all of its required criteria. In conclusion, it is essential for us to verify that what has been delivered is exactly what was requested from the outset.

"It's time to put our hard work into action."

At this point, it's essential that we deploy the software to a production environment so users can begin utilizing the product. Although several organizations choose to push their products through different deployment environments such as testing or staging before concluding its release, it enables any stakeholders an opportunity for risk-free exploration and gives them peace of mind knowing that final mistakes are being identified prior market launch.

Our plan isn't infallible, and seldom turns out as intended when it meets the test of reality. What's more, as external circumstances transform around us, we need to keep our software up-to-date in order to stay competitive. The DevOps revolution has truly transformed the SDLC, in that developers are now responsible for more aspects of the development process than ever before. The power behind 'shifting left' should also not be underestimated - when both development and Ops teams have access to identical toolsets which monitor performance and identify defects from start-to-finish, it seamlessly creates a shared language across platforms while speeding up handovers substantially.

After Understanding the SDLC, its crucial to understand an agile scrum process, including how to use a ticket system, report bugs, request features, and plan sprints.
