THE STAGES OF THE SDLC (SOFTWARE DEVELOPMENT LIFECYCLE)

You might think that a custom software application starts with just an idea and ends with deployment. However, to ensure the optimal functioning of your business tool, it is necessary to follow an action plan. This is referred to as the SDLC ( Software Development Life Cycle ) . This process includes several steps that go beyond just development. To better help you understand the phases of the software development cycle, we offer this explanation.

WHAT IS SDLC?

SOFTWARE DEVELOPMENT LIFE CYCLE DEFINITION

The Software Development Life Cycle ( SDLC ) is a process used to structure, plan and control the development of a computer program . It is divided into several phases ranging from needs analysis to software maintenance . There are different development cycles , depending on the method used .

IMPORTANCE OF THE SOFTWARE DEVELOPMENT LIFE CYCLE

Why is SDLC important for your project management? It allows you to delimit your development project . Therefore, you are assured of having software that meets your functional requirements . This allows for a better definition of objectives . We establish a roadmap for development teams . This allows them to visualize tasks and collaborate effectively.

The development lifecycle also ensures the quality of your business solution . We conduct regular checks to ensure the project moves forward smoothly.

THE STAGES OF SDLC

Before you start reading this, we’ll summarize everything for you in an infographic.

Requirements Analysis marks the beginning of the Software Development Life Cycle . It proceeds as follows.

Understanding the Context: We study your business environment. We ask you what your objectives and challenges are in order to visualize what the purpose of the software will be .

Requirements Identification : We gather requirements from end users, stakeholders, and internal teams to clearly define what the software must accomplish.

Requirements Analysis: We evaluate the information gathered to identify necessary features and priorities. This step often includes creating use cases and functional specifications.

Validation of Needs: We confirm that the identified needs are in line with the company’s objectives and user expectations.

Requirements Specification Document: We produce a document detailing all the requirements and specifications, which will serve as a reference throughout the development process .

This SDLC process allows you to identify the problems that are the source of your need.

SOFTWARE DESIGN

It determines the choices necessary for the development of your solution.

Choice of necessary resources: Which professionals will be mobilized (specialist developers, UX designers).

Technology Selection: Selection of Development Tools . Choice of Programming Languages

Software Architecture Planning : A perfect software architecture follows the best practices required by your information system and the technologies used.

Data modeling: Determining how data will be stored, organized, and manipulated. This involves designing database schemas and defining relationships between data.

Test planning: selecting the validation tests that will be used to ensure optimal software quality.

Our specialists help you define a clear and effective roadmap for each stage of your project, whatever your sector of activity.

PROPOSAL OF A SOFTWARE MODEL

This is a visual model of the software . This mockup is static and is intended to show the appearance and user interface of the software, without active features.

This is an important point in terms of user experience because it must be optimal. The interface must be ergonomic and intuitive so that your employees can easily access the different features of the personalized software .

Your end users will then have an overview of the business tool and how to use it. You once again have a role to play: validating this model. And stay here, because we will need you. The development phase of your software is beginning.
