Discover every little thing about the Systems Development Life Cycle

The Systems Development Life Cycle comprises the different phases that are carried out to develop a product, from the requirements gathering to the delivery of the product to the end-user. Within this cycle are included the activities oriented to validate the chosen architecture and the methods used.

Phases of the software life cycle

Software development requires a systematic methodology that allows the management of the project clearly and effectively to achieve the initial objectives. For this reason, the software life cycle is structured in different modules or stages that mark the distinct moments of the project.

The phases are:

Planning 

This first phase contemplates all the activities related to:

    • Evaluation of the scope and magnitude of the project
    • Feasibility stud
    • Analysis of the possible risks to be faced
    • Financial assessment of the project
    • Determination of probable execution times
    • Allocation of resources by defined activity

Analysis

This phase establishes what the software to be designed should do, its limitations, and requirements. It is possible to include the analysis of conflicts with other existing systems and their impact on the organization where it will be implemented.

Design and programming

The architecture of the system and the different possible options to build it are defined. It is a process that requires constant evaluation of potential failures and necessary adjustments.

Once the design has been chosen, programming is the process of building the system. It is also known as the coding phase.

It is essential to choose the most efficient programming language and evaluate its vulnerabilities as it is being developed. Once this stage is completed, it is crucial to document the code generated appropriately.

Testing

There is no infallible system. For this reason, at this stage, it is subjected to the necessary tests to identify possible failures and correct them. It is advisable to use several testing methods and tests for performance, functionality, integrity, and binding.

Implementation

It is the moment in which the software is installed on the client. At this point, the necessary configurations for the final customer, adaptability, and any issues related to the interaction with other systems are evaluated.

Maintenance

Although it is the last phase, it is not the least important. The maintenance to be offered is of three types:

    • Corrective (elimination of defects arising during its service life).
    • Adaptive (adapting the system to new customer needs)
    • Perfective (including new functionalities in addition to the original ones).

Different approaches, different models

The approaches to carry out software development will vary depending on the requirements and the products developed. Its life cycle will adapt. The important thing is that the team always keeps in mind to satisfy the customer’s needs and to offer the right solutions for each problem.

Hypernova Labs is faithful to its Agile (Scrum) and DevOps methodology. Our daily commitment is to fulfill the development process optimally and ensure that our customers feel that their future is in the best hands.
