SDLC Best Practices: Streamlining Your Development Process

In many cases, developers are the only ones responsible for figuring out requirements, writing code, and checking the validity of a finished product. Waterfall phases run sequentially, and every stage depends directly on the outcome of the previous phase (i.e., each step “waterfalls” into the next one). In a true waterfall model, the team never goes back a step after finishing a phase, so the model’s success rests on the team’s ability to avoid mistakes.

This is a key moment to improve scenarios based on real-world situations. Even though this process is automated (as a general rule), you and your teams should stay watchful since deployment is a complex process. Often, several systems and devices must be integrated and in some cases, more time and effort can be necessary to complete this stage successfully. The Software Development Life Cycle is a core part of the software development process.


The team should also create a project budget and timeline to ensure that the project is completed on time and within budget. The team should also create a quality assurance plan to ensure that the software meets the user requirements and is bug-free. Furthermore, the team should create a communication plan to ensure that all stakeholders are kept informed of the progress of the project. The team should also create a risk management plan to identify and mitigate any potential risks during the project. Finally, the team should create a user feedback system to ensure that any issues are identified and addressed quickly.

  • Big bang model is focusing on all types of resources in software development and coding, with no or very little planning.
  • This approach can cause serious delays and limit iterative work, often making implementing unscheduled features and changes much harder.
  • To help mitigate the amount of maintenance that needs to be done, teams may choose to first release the product to a smaller population of customers.
  • Compared to all other phases of the system development life cycle, the development phase is considered the most robust.
  • SDLC provides a number of advantages to development teams that implement it correctly.
  • The lifecycle defines a methodology for improving software quality and the overall development process.

The team often goes back a step or two in the SDLC to perform fixes or make improvements. In the greater context of management information systems or MIS, SDLC helps managers to design, develop, test, and deploy information systems to meet target goals. SDLC provides a number of advantages to development teams that implement it correctly. Projects pass through four main phases again and again in a metaphorically spiral motion. Developers must now move into a maintenance mode and begin practicing any activities required to handle issues reported by end-users. During the testing stage, developers will go over their software with a fine-tooth comb, noting any bugs or defects that need to be tracked, fixed, and later retested.

A Brief Overview of Software Development Lifecycle Tools

Both end-users and system analysts should see a refined project with all necessary changes implemented at this time. It also helps point out how those needs can be met, who will be responsible for certain parts of the project, and the timeline that should be expected. Given the method’s complexity, there are various methodologies out there to help you manage and control the entire process.

During this phase, the team will monitor the software and make any necessary changes to ensure that it continues to meet the user requirements. The team will also create a maintenance plan to ensure that any changes or updates to the software are properly implemented. The team should also create a post-implementation review to evaluate the success of the project and identify areas of improvement.

The Agile model

A version control system or VCS can greatly facilitate the work of developers trying to analyze changes and contributions to the overall code. This SDLC tool is a key element in managing software customizations that meet the needs of the project. Git allows developers to have multiple local branches that can be entirely independent of each other.

The design phase is where the real work starts, and company resources start to fund the project. It is also the phase where the team figures out what the finished product will look like once development is completed, omitting potentially risky design choices along the way. By the end of this phase, the team will know what features it will have, and how its inner workings will be built.

Product Maintenance and Enhancement

Once the requirement analysis phase is completed the next sdlc step is to define and document software needs. This process conducted with the help of ‘Software Requirement Specification’ document also known as ‘SRS’ document. It includes everything which should be designed and developed during the project life cycle. The systems development life cycle originally consisted of five stages instead of seven. The iterative model, being similar to the Agile approach, is a response to the waterfall model’s limitations. The whole product in the iterative model can be modified more seamlessly.

The first iteration implements a small set of the software requirements, and each subsequent version adds more requirements. Waterfall represents the oldest, simplest, and most structured methodology. Each phase depends on the outcome of the previous phase, and all phases run sequentially. This model provides discipline and gives a tangible output at the end of each phase. However, this model doesn’t work well when flexibility is a requirement.

The Different Phases of the System Development Life Cycle

By properly managing the analysis phase, the team will be able to create a successful software solution. The scope and objectives of the project are determined during the planning phase. It is the foundation stage that establishes the scope and objectives of the project. During this phase, the project team will define the project scope, set deadlines, and identify the resources needed to complete the project. The team will also create a project plan outlining the various tasks that need to be completed and the sequence in which they need to be completed.

Agile is often chosen by startups and smaller organizations when the project requires more flexibility. The two best-known methodologies within the SDLC are Waterfall and Agile. Ideally, Project Managers and Development staff collaborate with Operations and Security teams to ensure all perspectives are represented. At the end of the iteration, the work product is displayed to the client and important stakeholders. Once a business need is approved, the approaches for accomplishing the concept are reviewed for feasibility and appropriateness.

Software Development

In other words, a life cycle model maps the various activities performed on a software product from its inception to retirement. Different life cycle models may plan the necessary development activities to phases in different ways. During any life cycle stage, phases of the sdlc more than one activity may also be carried out. The SDLC life cycle process is repeated, with each release adding more functionality until all requirements are met. In this method, every cycle act as the maintenance phase for the previous software release.
