Software Design Process, Common Software Design Models

Let's learn the software design process through the following article.

Software design process is a term commonly used in the IT industry. This is a set of steps for designing and programming software. The design process is always researched and optimized continuously. To deliver quality software at the lowest cost and how to estimate software development time, save software development time. Nowadays, there are many different software design processes. Depending on the purpose and requirements, each company will choose an appropriate method.

5 steps in the software design process

Although there are many different software design processes, in general, the processes must meet the following 5 steps:

Step 1: Identify requirements and solutions

The first step is to work with the customer to understand their needs. From there, make detailed requirements tables as well as solutions to arising problems. These requirements and solutions will then be aggregated into a set of documents.

Step 2: Design the software

In the second step of software design is the design. At this step, the overall model of the software will be given. In addition, database design and features will also be covered.

Step 3: Programming the software

This is the main step in the software design process. At this step, programmers will proceed to write code. Modules and functions will be written in turn. Then they are combined into a finished product.

Step 4: Test

At the testing step, the testers will check the software to detect bugs and bugs. Test cases will also be applied in this step. The output at this step is the error and direction for the programmer to complete the final product.

Step 5: Deploy the product

The final step in the software design process is product implementation. This is the time to work and sign the minutes of software handover to customers or deploy the software for self-developed companies.

Common software design patterns

Nowadays, there are many different software design processes. These procedures will be tailored to each specific product and case. In general, there are mainly 3 main product development models:

Waterfall model

This is the traditional software development process applied by small and medium-sized companies. Waterfall model will help design software step by step. From requirements gathering, system analysis, coding to testing, deployment and operation. The steps will be performed sequentially, so the Waterfall model is suitable for projects with clear and detailed requirements. However, the disadvantage of this model is that it is rigid and difficult to handle when errors arise.

V-shaped pattern

The V-pattern is one of the modern software design processes. The letter V represents two branches, which are development and testing of the model. Each development phase corresponds to a test phase. This makes it easier for the company to detect and correct errors, if any. However, if the requirements of the customer or the company about the product are too high, the software development according to this model will create many inadequacies.

Agile model

The Agile model is now a very commonly used software design process. A complete Agile process breaks down into Sprint phases. Each of these Sprints will serve as a complete design process. However, Sprints only have a short duration of 1 to 4 weeks. After each Sprint, the product will be deployed immediately. The build and deployment steps are iterative to help improve the product continuously throughout the development process.

The software design process will help the company navigate the steps to be taken. Not only that, it also helps developers to cooperate well with each other. Currently, the software design process is constantly being improved to help the company achieve more optimal work efficiency.
