As a student, I combine the worlds of learning and blogging. With a thirst for knowledge and a will for writing, I share my notes through engaging blogs. These are the long boring lectures of my life I have survived through that I have summarized to you with a pinch of salt.

Computer system failures are a common issue, with computers crashing or malfunctioning unexpectedly. This often leads to mistrust in personal computers. The dependability of a computer system refers to its trustworthiness, indicating the user's confi...
With the increasing integration of computer systems into various aspects of our lives, the repercussions of system and software failures are growing. Failures, such as server software malfunction in e-commerce or errors in embedded control systems in...
User or customer testing is a crucial stage in the testing process where users or customers provide input and feedback on the system being tested. It can involve formal testing of a system commissioned from an external supplier or an informal process...
Release testing is the process of testing a particular release of a system that is intended for use outside of the development team. Normally, the system release is for customers and users. In a complex project, however, the release could be for othe...
Test-driven development (TDD) is a programming methodology where testing and code development are interleaved. It involves incrementally developing code alongside corresponding tests, ensuring that each increment of code passes its respective test be...
In the dynamic world of software development, a weld structure and organiser approach are essential for successful software. software process activities form the backbone of this approach, guiding developers through a systematic journey from concept to implementation. Software development lifecycle (SDLC) includes a series of steps and tasks involving the development of software Given diagram shows the detailed software process activities Now let us understand each of these activities in brief:-
Requirement analysis:- in this step, we understand and document the needs and expectations of end users and stakeholders It includes activities like elicitation and analysis, and documentation of functional and non-functional requirements. The purpose of requirement analysis is to establish a clear understanding of what the software is expected to achieve.
Example- imaging developing a social media app- This phase involves mapping out users' profiles, post creation and interaction functionalities.
Planning:- in this step, we develop a comprehensive plan that outlines the project scope schedule, resources and budget. It involves activities like task estimation, resource allocation, risk assessment and scheduling. Purpose purpose of planning is to set the framework for the entire software development process.
Design:- here we create a blueprint for the software based on specific requirements. Activities like architectural design, high-level design and detailed design. The purpose Is to translate requirements into a structural plan for implementation.
Example- In our social media app example, this stage involves designing the user interface, database structure and system architecture.
Implementation/coding:- the main process of implementation and coding is to convert the resignation to executable code activities like writing code, unit testing and integration of components in this phase. The purpose is to bring software to life and ensure it meets the specified requirements.
Example-In our social media app developers would write code for user registration login logout, post creation and interaction features.
Testing:- this involves the evaluation of the software to identify and fix defects Activities like unit testing, integration testing, system testing, and acceptance testing are carried out in this phase Purpose is to verify that the software functions are intended and made quality standards. This phase involves identifying and fixing bugs, and ensuring the software meets the specified requirements.
Example- In the social media app, the tester would validate that the user can register, create posts and interact seamlessly.
Development:- here we release the software for use by end users. Activities are installation, configuration and distribution of the software. The purpose is to make the software available on operational in the target environment. Development involves making the software available to users.
For example- when the social media app is released to the app store end user can start downloading and using it.
Maintenance and Support:- this involves addressing issues implementing updates and enhancing features post-deployment.Maintenance involves carrying out activities like bug fixing and modification and adapting to changing user needs. The purpose is to ensure the software remains reliable, secure and up to date.
Successful software development requires a well-organised and systematic approach to each of these activities to become good software.
