Modern software development methods

Continuous Improvement methodologies like Six Sigma encouraged strict guidelines for quality assurance. The 90s saw the dawn of open source software. Git was created to help manage these new distributed projects. Asynchronous communication over email and IRC.

Software development today primarily builds off the workflows established in the 90s open source world. Third party repository hosting services like Bitbucket have become central hubs for teams to use distributed asynchronous communication patterns around. Agile management methods are applied on top of these technologies to help coordinate and manage integration and release. In a group of software developers frustrated with the existing cumbersome management system, gathered and published the the agile manifesto.

Methodologies like Waterfall and TQM were born in the slower moving, less forgiving industries of physical goods manufacturing. Software is a much more forgiving and fluid end product than manufacturing.

Agile takes advantage of these properties and provides a complementary management methodology. Adoption of Agile development practices has given rise to new disciplines of software development. DevOps is a modern field of software development which focuses on support and automation for supplementary software development tasks. DevOps teams are primarily tasked to support and improve software developer efficiency.

DevOps teams build tools to automate and maintain mundane software development chores like infrastructure maintenance. Agile has been fantastic at optimising the development process. It has been so successful that Agile ideas and culture are continuing to expand to other areas of business like design and product development.

Extreme programming is a derivative of the Agile process. Extreme programing stresses customer satisfaction as the guiding force for development iteration cycles.

Extreme programing follows a five step iteration cycle. Learn more about extreme programing rules on the official extreme programming site. Lean offers a solid conceptual framework, values and principles, as well as good practices, derived from experience, that support agile organizations.

The waterfall model is a development process that originated in the manufacturing and construction industries. It is a highly structured process that strictly restrains movement from one phase to the next.

The motivation of this restriction comes from the prohibitively expensive phases of execution in physical environments. When applied to software these restrictions can feel draconian and counterproductive.

Learning software development can be a great exercise to open up new avenues for career growth. Being able to identify and discuss technical software development topics can improve your toolset in a software development organization. A basic knowledge of software development is becoming more and more valuable.

Understanding the design and implementation of how software works can help an individual operate more efficiently in personal and work life. Most modern business operations have some level of human-computer interaction. One of the best exercises for getting started is to observe, or participate in, a successful open source project, such as Git.

These projects maybe identified from software you already use and enjoy. They will have guidelines to contributing and have open message forums to follow along with discussion and execution. Additionally, reading this document is already an indication that you are ready to take the first steps and get started! Software development is a technical craft with a steep learning curve and deep history. It can be intimidating for outsiders and newcomers to approach.

The main focus of this model is to resolve the business problem rather than technical details. Thus it is most suitable for developing business systems. Lean Development Methodology focuses on the creation of easily changeable software. This Software Development model is more strategically focused than any other type of agile methodology.

The goal of this methodology is to develop software in one-third of the time, with a limited budget, and a very less amount of required workflow. The above software development methodologies are very important which are mostly used for various software development projects.

Moreover, all these popular software development methodologies work well in certain projects depending upon the nature of the project.

It often happens that one methodology that is suited for a particular project may not be suited for another project. Moreover, none of these software development methodologies are foolproof as each has its pros and cons. So, software developers must have information about all these methodologies before selecting any of these development methods for their software development projects.

For better results, it is advisable to consult a professional software development company. He is an accomplished Business Strategist and Tech Visionary with wide-ranging experience in the technology sector.

Home Insights Software Development. Last Updated on Dec 25, Agile Software Development Methodology Agile Software Development methodology is one of the best software development approaches that is used to design a disciplined software management process which also allows some frequent alteration in the development project. Advantages of Agile Development Methodology Customer satisfaction by rapid, continuous delivery of useful software. Human interaction is emphasized rather than process and development tools.

Customers, developers and testers constantly interact with each other. Agile methodology has an adaptive approach that is able to respond to the changing requirements of the clients. Direct communication and constant feedback from customer representatives leave no space for any guesswork in the system. Disadvantages of Agile Development Methodology In the case of some software deliverables, especially the large ones, it is difficult to assess the effort required at the beginning of the software development life cycle.

Agile focuses on working software rather than documentation, hence it may result in a lack of documentation. The project can easily get taken off track if the customer representative is not clear what final outcome that they want. Only senior programmers are capable of taking the kind of decisions required during the development process. Hence it has no place for newbie programmers unless combined with experienced resources. DevOps Methodology DevOps is a popular term gaining a lot of attention among all the software development methodologies because of the unconditional benefits it offers to its customers.

Advantages of DevOps Faster Process Multiple ongoing processes work simultaneously which makes the process faster and easier for businesses to process on time. By adapting to changes in the market, DevOps enables businesses to grow efficiently and drive definite business results.

Offers Rapid Deliveries Microservices and Continuous delivery are some elements of DevOps that offer business continuity and recent updates rapidly. Looking to add more structure to your software development workflow? Selecting the right software development methodology for your product organization depends largely on your team size, goals, and other factors. Here is an overview of the most widely utilized and recognized software development methodologies to help you decide which is right for your team.

When it comes to software development, Waterfall is the most traditional and sequential choice. First created in , Waterfall was one of the most prominent methodologies for several decades because of its plan-driven approach. Waterfall requires plenty of structure and documentation up front. It is divided into self-contained stages or steps. Should any changes need to be made or mistakes addressed toward the end stages, the Waterfall method generally requires a full restart.

Typically, one stage must be finished before the next can begin, which can help with organization and assignments. And because the full scope of the project is understood in advance, software progress can easily be measured. An iterative and incremental approach to software development, Feature-Driven Development FDD is derived from the Agile methodology and is considered one way to implement it. FDD still focuses on the goal of delivering working software frequently and is an especially client-centric approach, making it a good fit for smaller development teams.

Features are a foundational piece of FDD. Features are client-valued pieces of work that, according to the FDD approach, should be delivered every two weeks.

To produce tangible software often and efficiently, FDD has five steps, the first of which is to develop an overall model. Pros: DevOps is focused on improving time to market, lowering the failure rate of new releases, shortening the lead time between fixes, and minimizing disruption while maximizing reliability. To achieve this, DevOps organizations aim to automate continuous deployment to ensure everything happens smoothly and reliably.

Companies that use DevOps methods benefit by significantly reducing time to market and improving customer satisfaction, product quality, and employee productivity and efficiency.

Many consider the waterfall method to be the most traditional software development method. The waterfall method is a rigid linear model that consists of sequential phases requirements, design, implementation, verification, maintenance focusing on distinct goals. Pros: The linear nature of the waterfall development method makes it easy to understand and manage.

Projects with clear objectives and stable requirements can best use the waterfall method. Less experienced project managers and project teams, as well as teams whose composition changes frequently, may benefit the most from using the waterfall development methodology.

Cons: The waterfall development method is often slow and costly due to its rigid structure and tight controls.
