These days, you could find software for every single task, no matter, either be it sharing or storing data or data recovery or data mining or something else like that. Each and every software development process follows various life cycle phases. We have been developing various softwares for various tasks. If you would like to know about the life cycle phases what we follow for developing a software, then you have to read this article. Since, that is what we are going to discuss in this content. It is needless to mention that, life cycle contains various phases and all those phases are well connected and depend on each other.
The life cycle of our software development explains the phases of the software cycle. Added to that, it explains the order in which the phases will be performed. Every single phase provides some outcomes that are required by the next phase. All such demands of each phase will be defined as a design. Coding for each design will be produced. Coding will be different according to the design module. We and our development team follow six phases for designing a software which are as follows,
- Requirement gathering and analysis
- Implementation or coding
I know that, just the name of the phases is not you require. So, let us now discuss the six phases one by one in detail.
Requirement Gathering and Analysis
We solely perform this phase to collect the requirements of our business or a project. Our stake holders and project managers rely on this phase. It is more than important gathering the requirements and wants of the system. Only then, we can get an idea regarding where to start and what to include. The sure demands of our business will be outlined in this phase which are as follows,
- How will they use the system?
- Who is going to use the system?
- What data should be input by the system?
- What data should be output by the system?
The answers to the above-mentioned questions will be gathered during this phase. Besides just grouping the demands of our business, whether or not all such requirements can be implemented on the system will as well be discussed in this phase. Since, we will never incorporate the requirements that are impossible to implement or that does not makes any sense to our business.
At the end of this phase, a document that explains all the requirements of our business will be created and that acts as a point of statement or instructions for the next phase.
As per the requirement conditions of the first phase, we create the system and software design in this design phase. The design and structure of the system will help us understands the hardware and system requirements of the software model. Further, it helps in defining the overall architecture of the system or software model. Our professional designers will create the design model of the software and this design will serve as the guidelines for the upcoming phase of the software model.
In this design phase, our testers will come up with the test plan or approach. And they will say how to test the model and what to test in the model.
Implementation or Coding
This is the crucial phase of the software development and this is where the development begins. Once after creating the system design specifications and model, the work is separated into modules. And then, we will begin the coding for the design. This phase solely focuses our developer as the coding will have to be written for the design that was created in the design phase of the software model. This would be the lengthy phase of the development cycle as the coding has to be completed and it will take some time. Our developers will create accurate coding according to the design model of the software. And then, we will proceed to the next phase.
In this phase, the developed codes will be tested and examined whether or not it meets the requirements grouped and collected in the requirement phase. Testing is another important phase of the software development life cycle. And different types of testing will be performed in this phase which includes functional testing, non-functional testing, unit testing, system testing, integration testing and acceptance testing. The reason for executing testing is that, it determines whether or not the coding is done properly and exactly meets the requirements of the system. It is needless to mention, we do the coding perfectly and as per the requirements of the model. But to be on the safer side, we check these things ahead moving on to the next phase.
Once after the testing is done triumphantly, the product will be delivered to our customer or client for their operation. Later than the product or software is distributed to our end customer, they will foremost execute the beta testing. This beta testing will be executed to check whether the product needs any further alterations or it contains any errors or bugs. If so anything like that we mentioned is encountered during beta testing, they can report to us. And then, our development team will further work on the software to fix the errors or incorporate the required changes. After those things are done, final delivery will begin. That is, the customized product will be again delivered to our customer.
It is needless to mention that, a software may create some inconveniences every now and then. We fix or resolve those inconveniences soon at the earliest without keeping our customers or clients waiting for a long time. We provide best possible and reliable services to our customers in regards to the maintenance of the software.
These are the six phases of the software development life cycle that we follow for developing each and every software. I hope that, now you would have got some idea regarding the designing phases of our software development.
