What is SDLC? What are the Advantages and Disadvantages?
SDLC, which stands for software development life cycle, is the methodology that enables the processes to be managed correctly in order to develop high quality projects in the software world. In this article, what is SDLC, what are its advantages and disadvantages, what are its processes, what are its models, what is its expansion, how is it used? We will tell you important information where you can find detailed answers to your questions.
SDLC is a process that aims to produce high quality and low cost software in a short time. It provides a stage flow for the organization to test well and quickly produce ready-to-use software. This system, in which the stages follow each other, provides some advantages and disadvantages for software developers. We can list the advantages SDLC offers us during the software development phase as follows:
It provides a high level of management control and documentation.
It enables the software developer to proceed in a planned manner throughout the process.
It ensures that everyone working on the project understands the costs and resources required.
We can list the disadvantages that SDLC may cause in the development process of the software as follows:
It can slow down the project development process.
It provides low flexibility in the final stages of the project.
The testing phase can be very complex for developers.
SDLC Processes
SDLC processes are carried out in 6 stages. We can list these stages as follows:
1. Identify Current Issues
In the first step of the evaluation, identify existing or potential problems by obtaining information from customers, stakeholders and all project workers. After determining the strengths and weaknesses of the system you have created, try to solve the problems.
2. Plan
Planning is always very important in software development. At this stage of SDLC, you need to plan based on the costs and resources required for the project. Besides, you can develop sub-plans to soften the risks.
3. Design
At this stage you should adapt the software specifications to the design plan. Afterwards, you should review this plan together with the stakeholders and the project team and improve its deficiencies. Gathering feedback is very important for the healthy execution of the project.
4. Structure
At this stage of SDLC you need to come up with naming and styles for the files. The configuration process allows you to manage easy-to-understand and test-ready code.
5. Test
As you approach the end, at this stage, you should apply detailed tests to the code directories to find all the mistakes and deficiencies. You can also measure whether the code meets the requirements this way.
6. Distribute the Software
After you have completed all the previous stages of SDLC, you can present the product to the users in this final stage.
What are SDLC Models?
There are different software development lifecycle models designed during the software development phase. Here are some important models of the SDLC lifecycle:
Waterfall Model
Software requirements analysis is a software development model in which the design, implementation, testing, integration and maintenance steps are thought of like a waterfall flowing down.
RAD Model
It is a model similar to the waterfall model. It is a model that aims to develop a faster and better system by using focus groups to collect system requirements.
Spiral Model
In this model, alternatives and constraints are created in order to achieve the determined goals in the stages provided by the loops in the spiral.
V Model
This model includes validation steps combined with the coding scheme.
Incremental Model
In this model, also known as the waterfall cycle, requirements are grouped at the very beginning of the project. More functionality is added with each release until the SDLC process meets all requirements.
What does SDLC stand for?
SDLC is formed by combining the initials of the words Software Development Life Cycle. This system, which means software development life cycle, covers the entire software creation and ongoing software development processes.
How to Use SDLC
SDLC is used by software developers to advance the process from writing code to testing in a project in a healthy way. In order to use this process, which consists of planning, coding, designing, testing, monitoring and distribution stages, the stages are followed in order. At the end of the process, it is aimed to develop products that can be of interest to the user, with software that has readable and complete code sequences.
