The development of websites and applications is a complex and prevalent field in the software industry. Many companies across various industries aim to establish an online presence, either through a website or social media, to promote and sell their products. To accomplish this, it is important to have a skilled software development team and efficient software delivery methods. Here, we shall look at the two in-depth and check out the differences between the two.
What Is Software Development?
Software development refers to the process of creating, designing, implementing, and maintaining software that serves a specific purpose and addresses user needs. The software itself is a set of instructions or programs that tell a computer what to do, it is not tied to any specific hardware and allows a computer to be programmed. Software development can be divided into three main categories: system software, programming software, and application software. System software focuses on essential functions such as operating systems, hardware management, and other operational-level needs. Programming software provides developers with tools such as text editors, compilers, and debuggers to write code. Application software is designed to assist users in performing specific tasks, examples include office productivity suites, media players, and security programs.
What Is Software Delivery?
Software delivery encompasses the entire journey of bringing a software product to the customer, including its conception, development, and final distribution, which is often in the form of purchasing and installing a license. The term can refer to the initial stages of the process, where a company’s teams work to ready the software for deployment to customers. It may also refer to the customer’s method of accessing the product.
Software delivery models refer to the techniques and strategies used by teams to bring a software product to the market. These approaches can also be referred to as the software delivery lifecycle, pipeline, or process. There are various models that companies have developed and no one-size-fits-all approach. Often, businesses use a combination of software delivery models. In the past, the waterfall model was considered the industry standard for software development, but now the agile methodology is more widely used. The agile approach is often associated with other methods, such as DevOps, CD/CI (Continuous Delivery and Continuous Integration), Kanban, and Scrum.
Software Development vs Software Delivery
This table compares the goals, processes, timelines, iteration, endpoints, and dependence of these two phases:
|Software Development||Software Delivery|
|Goal||Creating website or application||Delivering website or application to the client|
|Process||Writing code, designing interface, and user experience||Delivering software for client feedback and approval|
|Timeline||Pre-delivery process||Post-development process|
|Iteration||Ongoing process||Iterative process|
|Endpoint||No definite endpoint||Endpoint is delivering software to the client|
|Dependence||Client demands and feedback||Completion of the software development process|
3 Types of Software Delivery Models
#1 The Waterfall model
The waterfall approach is a linear, sequential software delivery model where each phase of the process depends on the completion of the previous one. It is named after its continuous “downward” flow, in which the process moves in a linear fashion from conception to deployment, following a set series of steps. This method is considered less flexible as compared to other approaches. It was originally used in industries such as manufacturing and construction, where mistakes made in an early stage could affect the whole project. In software development, this approach can take months or even years to complete and may be seen as inflexible and slow, as requirements and technology change quickly. While in some cases, this linear approach might be necessary, in today’s fast-paced and rapidly changing industry, it is less suitable for software development.
#2 The Agile model
Agile software development and delivery emphasizes lightness, speed, flexibility, and the ability to adapt to changes easily. Agile practices involve discovering requirements and developing solutions through the collaborative effort of self-organizing and cross-functional teams, in close collaboration with the customer(s) or end-user(s). Rather than approaching software development like a construction project, built from the ground up in a step-by-step manner, the Agile model breaks the project down into smaller components that can be developed independently by a team specializing in a specific feature or functionality, then these components are integrated to create the final product.
This approach allows for a software delivery lifecycle that is more flexible, collaborative, efficient, and iterative. Using the agile approach, developers can meet their goals in a matter of weeks, which allows tech companies to release new products and updates much faster and more efficiently. The Agile method is also associated with other related models and methodologies, such as DevOps, CD/CI (Continuous Delivery and Continuous Integration), Kanban, and Scrum, they all strive to create an efficient and fast software delivery process without compromising on the quality.
#3 The DevOps model
DevOps is a software development and delivery model that emphasizes collaboration and communication between development and operations teams. They help to improve the speed, quality, and efficiency of software delivery. The goal of DevOps is to bring development and operations teams together to work on the same goal, to deliver software quickly and reliably, using a set of practices and tools to automate and streamline the software development and delivery process. DevOps aims to promote a culture of continuous delivery, testing, and integration. The model seeks to minimize the gap between development and operations, breaking down the silos that traditionally separate these teams, to increase the speed at which software is delivered and the quality of the final product. It also encourages frequent, small releases, rather than infrequent, large releases.
The difference in roles and responsibilities between software development and software delivery teams
In the world of software development, there are a number of different roles and responsibilities. They must be carefully managed in order to ensure the successful creation, delivery, and implementation of new software applications. Among the most critical of these roles are the software development team and the software delivery team. Each of which plays a crucial role in the overall success of the project.
Role and Responsibilities of the Software Development Team
The software development team is responsible for creating the code. They also desig the user interface, and building the functionality of the software itself. This team is typically made up of skilled software engineers and programmers who work together to create a product that meets the needs of the client or end user. They are often the first group to work on a project and their work are critical to the success of the entire software development process.
Role and Responsibilities of the Software Delivery Team
The software delivery team is responsible for ensuring that the software is properly tested, packaged, and delivered to the client. This team is often made up of quality assurance professionals, deployment specialists. And project managers who work together to ensure that the software meets all of the necessary requirements and is delivered in a timely and efficient manner. Their work is critical to ensuring that the software is ready for use by the end user. Any issues or bugs are identified and resolved before the software is released.
While there is often some overlap between the responsibilities of the software development team and the software delivery team. It is important to understand the differences between the two. By doing so, project managers and other stakeholders can better allocate resources. They can manage timelines, and ensure that all aspects of the software development process are managed effectively. Ultimately, by working together and leveraging the strengths of each team. It is possible to create high-quality software applications that meet the needs of clients and end-users alike.
In conclusion, software development, and software delivery are both crucial aspects of the software industry, with different goals and processes. Software development involves the creation, design, implementation, and maintenance of software. While software delivery focuses on the entire process of bringing a software product to the customer. The software delivery lifecycle can involve various approaches. The agile methodology and DevOps model have gained popularity due to their efficiency and flexibility. Moreover, software development and software delivery teams have different roles and responsibilities. Collaboration between them is essential for the successful creation and delivery of software product. Overall, a well-executed software development and delivery process can help companies establish an online presence. They promote and sell their products, and stay competitive in today’s fast-paced and rapidly changing industry.
