Global spending on enterprise software is everywhere US $ 605 billion.. To ensure an efficient production process, the team incorporates several methodologies and approaches into the development life cycle. Two of them are Agile and Waterfall. Agile has gained momentum in recent years, but waterfalls still have their place. While thinking of software as a layered technology, the waterfall approach can be used in parallel with this idea and acts as a parallel and complementary concept. This article briefly describes how the waterfall approach works and how it easily blends with the concept of software as a layered technology.
How does waterfall development work?
Waterfall provides a step-by-step approach to software development. It consists of 6 different phases.
In many respects, waterfalls can be compared to traditional assembly line-based production processes in the automotive industry. The decision maker decides what is needed, the designer models the vehicle and its components, the product is built on the assembly line, tested, released and then maintained by the dealer’s mechanic. In this sense, waterfalls can be used not only in information technology, but also in a variety of development scenarios and in many industries.
In the context of software development, waterfalls may be using the following steps:
- Requirements. The product team and C-level executives determine what the application needs to achieve.
- design. Software designers use code to plan how to achieve their primary goals.
- development. The development team builds the software iteration.
- test. An internal team tests the software to see how well it works. This is sometimes called an alpha test. If execution fails, the process returns to either the design or development phase.
- Deployment. After passing an extensive testing process, the application is open to the public.
- maintenance. The solution is updated when the general public and internal team members discover a problem. The team will release new versions and patches that address feature and security concerns.
Proper requirements and design are required for a successful waterfall process. All stakeholders need to be at the table or have someone else represent their needs. In particular, creating a new iteration can take longer in the life cycle. This is part of the reason developers came up with an agile approach. However, waterfalls work the same in many situations. This also includes within the context of software as a layered technology that includes four key aspects.
- Focus on quality
Here’s how they intersect.
How the concept of waterfall and software as a layered technology can work together
The key to successfully linking the layered aspects of waterfall and software development is to use layered principles to evaluate and design each phase of the waterfall process. In short, it uses the four elements of the software as a layered technology to balance a series of checks and ensure that waterfall developers meet their core goals. Here is an example of what it looks like.
Software as an example of layered technology and waterfall
Suppose your organization wants to develop a mobile customer relationship management system. Especially for remote workers who want to use mobile devices while supporting the sales process. The CIO has decided to use the waterfall framework.
Step 1: Establish how layered technology principles apply
Product managers sit with stakeholders and they work together to specify:
- Quality: The purpose of the app and how to create an effective user experience (UX)
- Process: Databases and other dependencies that enhance the coding languages, tools, frameworks, and apps used to build user interfaces (UIs).
- Methods: Steps used for communication, evaluation of requirements and their fulfillment, application design, testing, and support
- Tools: Technology used to execute processes and methods while maintaining quality
Step 2: Build a waterfall structure using the principles of layered technology
The project manager makes all decisions based on layered principles when deciding which team members to include in the waterfall development and what they will do.
- A team of product managers use layered technology to evaluate the results of each waterfall phase. quality standard.
- The processes and frameworks that drive the design, development, testing, deployment, and maintenance phases are regularly checked against those determined in Step 1, using layered technical principles.
- The methods used in all phases are built on the methods chosen while applying the hierarchical technical principles.
- The tools to be implemented are selected based on the tools identified in the layered technology evaluation process.
Ultimately, the team will use waterfall to create and maintain apps that adhere to the principles of software as layered technology. In this way, you can maintain a logical, sequential approach to making waterfalls effective, while ensuring that your processes and products are software-compliant as a principle of layered technology. Not only do you gain the strengths of both worlds, but the two worlds complement, support and improve each other.
