Software (Systems) Development Life Cycle

The software development life cycle (SDLC) is the structure that contains the processes, activities and tasks related to the development and maintenance of a software product, covering the entire life of the system, from the definition of the requirements until the end of its use.

SDLC - software Development Life Cycle

The SDLC is part of Ungoti’s computational DNA and for this reason we support the entire project life cycle through the following phases:

SDLC - Phases

The Software Development Life Cycle is initiated. The client requests a specific software product or functionality. We capture the specific needs and submit the application for software development.

Software development begins with an initial planning phase including a requirements analysis. We examine the client’s requirements and analyze which are unclear, incomplete, ambiguous or contradictory. It is investigated in depth and practical demonstrations are made, We include key users. The requirements are grouped into user requirements, functional requirements and system requirements. The collection of all the requirements is carried out: studying the current software that the client has (if any), interviewing users and developers, consulting databases or through questionaires.

In the next phase the scope of the project is finalized and documented.

After the collection of requirements, a plan to process the software is devised. An analysis is done to confirm that part of the software covers the requirements of each user. The financial and technological feasibility is investigated. Algorithms are used to determine if the software project is feasible or not.

In this step the project team allocates resources and plans the duration of the project. Product limitations are sought and the impacts of the project on the entire organization as a whole are identified.

In this phase the solution begins to be visualized with the help of the previous phases. A logical and a physical design is made. Metadata, diagrams or pseudocodes are created. The duration of this phase varies from one project to another.

This phase is also called the’programming phase’ or the ‘development phase’. The most convenient programming language is chosen. Executable and error-free programs are developed efficiently. Our approach is to build pieces of functionality. Therefore, delivering concise units of functionality. At the end of this phase a MVP (minimum viable product) is delivered or the software is fully developed and ready to be implemented.

The Software may need to be integrated with libraries, databases or with other programs. This phase of the SDLC integrates the software with external entities.

This phase together with the development phase, goes into a continuous cycle until development and testing are completed. We test, test and then retest as much as needed until the functionality is 100%.

In addition, evaluations are made to avoid errors. These include, the evaluation of modules, programs, products, and finally evaluation with the final client. Finding errors and fixing them on time is the key to producing reliable and efficient software.

In this phase the software is installed. Integration, adaptability and portability are evaluated and any necessary configurations are installed.

This is one the most interesting phases in the Software Development Life Cycle. The training! User adoption is very important and for this reason, we offer initial training for each user. It is important to check the level of use, the user experience and resolve any difficulties that may arise when facing a new system or platform.

Last but not least, maintenance is one of the key elements of success of any project. In this phase, small errors are minimized, the proper functioning of the software, its efficiency and stability are confirmed. The project is already completed and we need to monitor and maintain continuously to ensure that the project continues to execute well.
If necessary, additional training is given, or documentation is provided on how to operate and keep the software in perfect working order. User or technological environments are adapted, maintaining the software, updating the code and configuration.
The software is effective when used properly and that is why maintenance and improvement of software products is crucial to correct defects that arise or to meet the requirements of the software.
