Software Development Write For Us – We could define software development as creating a program incorporating all stages throughout the systems development life cycle. They do this using one or more specific programming languages that provide functionality to address business or personal goals.
As we have mentioned, software development is a planned initiative based on a series of steps and stages that result in creating operational software, including its design, development, testing, and implementation.
For those unfamiliar with the subject, the software is a set of instructions or programs that tell a computer what to do. It is hardware-independent and makes devices programmable.
Types of software development
There are different types of software development that a programmer can work on:
- System software: Also known as operating software. It’s what makes a digital device work, and it’s made of complex code.
- Programming software: These are the tools that programmers use to help clean up the software and make it run smoothly. You can include devices such as debuggers or text editors.
- Application software: Allows the end user to carry out a task they want to perform. Application developers specialize in designing application software for mobile phones.
Software development methodologies
We can summarize the software development life cycle models in 6. Each of these approaches differs in some way from the others, but they all have a common purpose: to help teams deliver high-quality software as quickly and cost-effectively as possible :
agile
In the Agile model, detected errors are perceived as positive. This methodology produces continuous release cycles, each with minor changes from the previous release.
At each stage, the product is tested. This helps teams identify and address minor issues before they become more prominent and engages business stakeholders for input throughout the development process.
waterfall
The waterfall is considered the oldest of the structured SDLC methodologies. It has a straightforward approach: finish one stage and move on to the next. Each one is based on the information from the previous stage and has its own project plan. There is no way back. The downside of this methodology is its rigidity, as delays can throw off the entire project schedule.
spiral
It is one of the most flexible. The project goes through four phases (planning, risk analysis, engineering, and evaluation) over and over again in a figurative spiral until it is complete, allowing for multiple rounds of refinement.
It is often used on large projects and allows development teams to create a highly customized product and incorporate user feedback from the start.
Iterative
This model is based on repetition. It is based on trial and error. Instead of starting with general requirements, project teams implement software requirements and then test, evaluate, and fix additional requirements. A new version of the software is shaped with each phase or iteration.
DevOps
The DevOps methodology grew from applying Agile and Lean practices to operations work.
In this model, development and operations teams work together to accelerate innovation and the implementation of higher-quality software products and functionality. Product updates are small but frequent. Discipline, continuous feedback and process improvement, and automating manual development processes are all hallmarks of the DevOps model.
Read
The Lean process seeks to work only on what is due at that moment. There is no place for multitasking. They also focus on finding opportunities to reduce wasted time and resources during the software development process, from eliminating unnecessary meetings to minimizing documentation.
Steps in the software development process
There are seven main stages of the system development life cycle:
1# Planning
The planning stage is the phase in which developers plan the next project. It helps define the problem and scope of existing systems and determine the goals of new systems.
Developing an advanced scheme will detect problems before they affect development and help secure the needed funding and resources. The project schedule is also established at this stage.
2# Analysis
Second, we have the analysis stage. This stage includes gathering all the necessary details for a new system and determining the first ideas for prototypes.
In this sense, developers must define the requirements of the prototype system, evaluate the alternatives to the existing ones, and investigate and analyze all aspects to determine the needs of end users.
3# Design and prototyping
Third, we have the design stage. At this stage, practitioners will need to describe the details of the general application and more specific ones, such as user interfaces, systems, networks, and databases.
In addition, they will also need to convert the SRS document they created into a more logical structure that can then be implemented in a programming language. Operation, training, and maintenance plans will be drawn up so that developers know what to do at each cycle stage going forward.
4# Development
This is the part where you start writing the code and build the application according to the criteria and requirements specified in the previous stages.
This is where static application security testing or SAST tools come into play.
The planning ahead and description should make the actual development phase relatively easy. Developers will follow the organization’s coding guidelines and use tools such as compilers, debuggers, and interpreters. Programming languages may include essential elements such as C++ or PHP.
5# Tests
As we already know, not everything is software creation. The tests are a fundamental part of ensuring that they will work and meet the proposed objectives. Therefore, at this stage, we must review the software step by step, trying to detect any error or defect we must correct. We must also ensure that it meets the defined quality standards.
Testing can be an extremely short or time-consuming phase depending on the developers’ skill, the software’s complexity, and the end user’s requirements.
6# Implementation and integration
Once we have it more than tested and corrected, we will integrate the different modules or designs into the main source code, taking the opportunity to detect more errors. The information system will be combined and eventually installed. After this stage, the software is ready for the market and can be provided to any end user.
7# Operations and maintenance
But this process doesn’t end when the software hits the market either. At this point, developers should perform maintenance and start practising the activities necessary to handle issues end users report.
In addition, they will be responsible for implementing any changes that the software may need after implementation.
