SOFTWARE ENGINEERING METHODS AND TECHNIQUES:
Nowadays, you have control of everything at your fingertips. Advancement has gone beyond imagination all because of the software development industry. Limitless is what I would call the world of software development. To create a specialized information system, software development methodology is essential for planning and controlling the procedure. The following are the methods being used for software development:
Waterfall Model:
In software engineering, this method is one of the most traditional methods of explaining development. It clarifies the process through a linear flow and step-by-step sequence so that one can easily understand one procedure at a time and after its completion, the next one gets started. If a certain level is completed and the process has moved on to the next level, reverting and making changes after that is not possible.
Prototype Methodology:
It’s a special development procedure in which a developer first makes a sample or prototype to see whether it is functional or not before handing it over to customers and making essential changes as per demand. The best thing about this method is it tends to resolve multiple issues occurring in the waterfall method.
Agile Methodology:
This method allows recurrent alterations and is used for the articulation of a well-managed project management procedure as an innovative approach. It acts as a theoretical outline for many different software engineering projects. This methodology also minimizes risk by the development of software in short time cycles called iterations lasting from a week to 30 days.
Rapid Application Development:
This methodology provides quick results with rapid application development. Also, it supports other development methodologies. To take full advantage of development software, rapid application development is essential. Participation as an active user gets highlighted as it is designed to increase the functionality of the complete development procedure.
Dynamic System Development Model Methodology:
The above-mentioned method has been derived from the rapid software development method because of its repetitive and incremental approach highlighting the participation of the user. This methodology provides the final product within the provided time frame and allocates the budget properly for software development. Cost controlling and time frame are key points due to which this methodology is high in demand.
Spiral Model:
This methodology eliminates the majority of early risks meant to occur in the development of a project. As the development process starts engineers keep looking to find risks during the process. They also plan for iterations of the spiral. Being consistent, keen, observant, and familiar is what makes this spiral software development methodology successful.
Extreme Programming Methodology:
It is an agile methodology which nowadays is known as XP methodology. The customer is highly involved in the software development in XP methodology. Mainly, it is used to make software in a very unstable atmosphere. It also provides great controllability while modeling and aims for cost-cutting of software. Alterations in output at a future stage of a project can be very costly. Communication is very simple and transparent in the XP method. Sharing knowledge with teams and dependency on each other makes it better.
Feature-Driven Development Methodology:
This method serves teams working on a project with object-oriented technology because of its iterative nature. It has a phase-based method for a repetitive approach. It’s also known as FFD methodology which is very applicable to use against diverse complexities.
Joint Application Development Methodology:
JAD is a system that involves continuous interaction with end users and designers of the software in the development procedure. This was first used to design computer-based software, but it is not only limited to that. I can be applied to any software development process.
Lean Development Methodology:
As the name suggests, this method emphasizes the development of very easy-to-use software which should be easily manageable. This development technique is better than any other form of agile methodology because the procedure is to improve the software in 1/3 of the timeframe with a restricted budget and lesser workflows.
Rational Unified Process Methodology:
This method is object-based and is divided into different stages of modeling, enactment, design, disposition, and testing. It helps a developer by already stating guidelines for every stage separately.
Scrum Development Methodology:
This agile methodology is used as a priority by developers because of its applicability to constantly changing and developing projects. It starts with very short planning and comes to an end conclusively with a series of iterations for the final software. It’s the best method to easily get ongoing projects on track.
MODELING TOOLS FOR SOFTWARE DEVELOPMENT AND ENGINEERING:
Many options are available in the market for what platform you are going to use for programming. Below is the list of tools commonly used in development daily.
1. Terminal:
Instead of going through the whole menu, Terminal makes your job easier to move between files while downloading applications and doing several other things with a single command. It depends on what kind of work you are doing; some developers use it less often and some use it daily.
2. Tmux:
If a developer needs to work at different open terminals for different processes that is where the tmux comes in to make it easy. It helps in dividing windows into different panes to make it easy for the developer to work with the flow.
3. Docker:
It allows a developer to package the program into the containerized filesystem. The container is moveable and can be executed anywhere. In this tool, the software will not be dependent on its environment as you will get libraries, code, system, etc. everything within docker. A good point of docker is it can be easily run on any infrastructure, computer, or cloud. It makes it easy for developers to collaborate due to its common framework. Docker allows you to fix issues and ship software on time.
4. Intellij:
Tools needed to develop a platform are always integrated into an IDE (Integrated Development Environment) i.e., editor, debugger, compiler, etc. Its user-friendliness and auto-completion capabilities help it to stand out. Navigation is much easier to catch errors and rectify them, quick fixes also come in handy.
5. Slack:
When it comes to team communication, that’s where Slack comes in as a great which can be used everywhere i.e., for any platform be it android or iOS. Channel creation is a good feature in it which helps to create projects, topics, groups, etc. with easy switching. Private conversations with members are also possible. The interface is very interactive. You may share data, comment or tag other members with the availability of the log side by side.
6. Chrome:
As we all know it’s a universal platform being used by almost every programmer in the world. It is known for its very clean and simple user interface. A huge library of extensions and add-ons is a plus. For developers, the console is very handy and quick and acts as a charm for front-end developers.
7. Feedly:
It is like a news feed of your interests and is very easy to use due to personalization options. You may set up all your favorite platforms like YouTube etc. and stay updated because of Feedly’s continuous and timely updates.
8. Jira:
Jira helps by coming in for phase-wise developments when agile teams work on software. It helps to generate reports to visualize how much work is completed and how much is left. It’s very customizable with some powerful tools for developers.
9. Git:
It is an open-source platform that requires regular iterations from the developer until and unless it reaches the final stage. It’s very popular because of its conflict management ability by allowing the development of code ranges.
10. GitHub:
It is an online platform that allows a developer to upload his/her code with the option of keeping it public or private. It also allows developers from all over the world to interact, share and help each other having a huge project base.
11. Stack Overflow:
It’s a platform on which a developer can get all his/her questions answered. It has a huge community of developers who can answer the easiest as well as the toughest questions from fellow developers. It’s a good platform to share knowledge and learn from its huge library.
12. Sublime Text:
Multiple selection options with keyboard shortcuts are what make sublime text editor great which allows multiple changes at a time with a nice UI.
13. Jenkins:
It acts as a middleman between your code and program server and continuously updates as it finds any iterations. Plugins developed for Jenkins make it easy for a programmer to code.
14. Confluence:
This tool is used for team collaboration by putting up ideas on the platform with documentation to develop it better. Everyone can contribute to the projects created on the confluence with up-to-date status of work at the same time.
15. Skype:
As we all know, for teamwork or to fill up the communication gap for developers, it’s the best tool available out there. It’s almost used by every programmer to collaborate. To work remotely or with a client in a different country, skype helps a lot. The best part, it is free.
So, these are the essential tools for a developer which I believe help a lot to work daily. The structure of software engineering teams includes the programming teams and software engineering roles and tasks. You should explain how the roles are interlinked.
