INTRODUCTION

The Software Development Life Cycle as a collection of rules and practices helps to connect tech, non-tech team members and project stakeholders to transform your exceptional idea into a unique software product or solution.

5 stages of software development

Software product development is a highly organized process with precise procedures and strictly defined steps known as Software Development Life Cycle (SDLC). Whenever you need a sophisticated system, software suite, or end-user web or mobile app; your project delivery largely depends on a set of processes practiced by the development team.

This process is normally called the Software Development Life Cycle (SDLC) and typically involves distinct stages which we will discuss in this article.

WHAT IS SOFTWARE DEVELOPMENT LIFE CYCLE?

The Software Development Life Cycle refers to the phases of work involved in producing software applications. Each phase corresponds to a role or responsibility that contributors make to the project. Contributors must understand, manage, and optimize to deliver their services with speed and performance.

These 5 stages of work include:

  1. Requirements gathering
  2. Design
  3. Coding
  4. Testing
  5. Implementation and maintenance

Each phase will produce deliverables required to execute the upcoming steps in this software life cycle. The requirements are eventually translated into perfected designs. The code is delivered in accordance with plans which are termed as the development phase. All these stages are executed with the help of a team of software development professionals who are crucial for each step. No stage is accomplished without another.

REQUIREMENTS GATHERING

Before the team of software developers can conjure the general idea for any software project it is essential for the team to gather the requirements. At this point the prime focus of the stakeholders and project managers is to define what the end product will be.

requirements gathering

The requirements of the software are determined at this stage. Discussions are held between the various stake holders, managers, and users to find out what the particular software will be used for. Who will use it and how will they be using it? Information regarding what kind of input is required and what output is expected is collected during this stage. Once the information is collected, it is analyzed to see if the requirements can be incorporated into the software that is to be developed. After which, a Scope of Work document is developed to be used as a guide for the next stage.

This system development life cycle stage helps meet the client’s requirements by collecting the information in a single document to create a plan to develop the solution.

During this crucial software development stage, we spend time learning your business processes, pain points, challenges, technical ecosystem and goals. Once that information is gathered, we define goals and present you with a Scope of Work.

DESIGN

Once you validate your need for custom software, set your goals and outcomes, and agreed upon the scope of work with your development team, it’s time to get into the design.

software design

Developers will first outline the details for the overall application, alongside specific aspects, such as:

  • User interfaces
  • System interfaces
  • Network and network requirements
  • Databases

CODING/DEVELOPMENMT

After receiving the design guidelines for the software to be created, the tasks in the design stage are divided equally into various units and modules. This is the stage where actual coding begins. 

The development stage is the part where developers actually write code and build the application according to the earlier design documents and outlined specifications. Furthermore, it is the longest stage as it’s the backbone of the whole process and there are a number of vital things to pay attention to.

In the development and coding stage, remember:

  • With the wireframes of the software laid out the coders are free to dive into the nitty-gritty. This is the bulk of the project where the heart of the software is built! In other words: this is where the ideas laid out in the first 3 steps become reality as a team of programmers bring them to life.
  • Coding tasks are allocated as delegated by the scope of work created during steps 1 & 2 in a process called “task allocation”. This subdivision of labor ensures all programmers know what areas of code they are responsible for which will maximize efficiency.

Developers will obey specific predefined coding guidelines during this process. They will also use programming tools such as compilers, interpreters, debuggers to build and execute the code.

TESTING

After the development of the code it is tested to see if it meets all the requirements that were determined in the first stage. Various testing such as system testing, unit testing, acceptance testing, and integration testing are carried out. During the testing stage, developers will analyze their code with a fine-tooth comb; noting any bugs or defects that need to be tracked, fixed, and later re-tested.

Quality assurance teams test the software against the requirements to make sure that the software is solving the needs addressed and outlined during the planning phase.

It is important to remember: 

  • After programmers have dotted their i’s and crossed their t’s the software is sent to the quality control department of the team to test the product thoroughly for errors. In successful tests, a certain number of glitches are bound to be uncovered. They are fixed before any user ever experiences the would-be error message.
  • Once every test can be passed without error the software is sent to be implemented.

Towards the end of the project, user acceptance testing should be performed to make sure the system has met the goals that were expected. If something unexpected were to occur the team can go back and redesign and rework their coding and perform additional analysis.

IMPLEMENTATION AND MAINTENANCE

After testing, this is the stage when the actual installation of the crafted solution takes place. It’s done step-by-step according to the implementation plan. The newly built and tested application is moved to production including data and components transfer while during the next releases only the specific changes will be deployed.

 It is important to remember:

  • The software is opened up a beta phase which involves real use by the clients and companies which will be adapting it upon launch. 
  • If any error is experienced, it is reported to the quality assurance team members who work with the programmers to patch a repair. After a prearranged amount of time during which the software can be operated error free, it is ready to officially launch to all users.

When the software passes through all the stages without any complications, a maintenance cycle is to be performed in which it is updated and modified from time to time to adapt to changes. Many models of system development life cycle came from the idea of saving effort, money and time.

CONCLUSION

SDLC can be a great tool that can help us with the highest level of documentation and management control. Failure to consider customer’s requirements, users or stakeholders can lead to project failure. The goal of software development is to locate predictable and repeatable methodologies which helps improve overall productivity as well as quality.
