Custom software development lifecycle is quite a challenging process.

In this article, we are going to dive deeper into the process of custom software development and single out the main stages of its life cycle. Keep on reading and you will find out all the necessary steps to get a high-quality product.

Custom Software Development Lifecycle Step By Step

In a nutshell, a custom software development lifecycle (SDLC) resembles building a house. First of all, you need to make strategically important decisions so that you can start writing a code from scratch without any unexpected issues. All of this should be done on a pre-development stage. The following stage is the development itself and the work of a custom development team continues when the software product is launched.

Pre-development Stages

The development process begins long before writing the code. Here are the main steps the custom development project goes through:

Pre-development Stages
Step 1. Consulting

The very first thing you need to do is to get in touch with the development company and define whether it fits your custom development project. Here are the main points to consider:

  • communication methods and tools
  • portfolio
  • technology stack they worked with
  • real reviews and recommendations
  • location
  • pricing models

Step 2. Planning and Requirements

This stage is essential for custom SDLC. Planning lays out all the steps you should make and singles out all the project peculiarities, including:

  • specific business requirements
  • technologies to be used
  • potential risks
  • deadlines and meetings schedule
  • approximate budget
  • features

Step 3. Design

UX Design

A UX designer is responsible for this custom software development stage and makes final decisions on what the final product will look like. Attractive and practical design and brand image play an important role in user experience. That’s why you need to develop a simple, intuitive, and appealing design.

Step 4. Software Architecture

Focus on functionality such as third-party integrations, APIs, the tasks of every module, and how modules are going to work together. For large-scale projects, this stage can take more time but still shouldn't be omitted.


Having made all the decisions and defined all the technical specifics of the custom product, the project moves on to the development stage.

Step 5. Writing the code

Coding is the most time-consuming stage of the whole software development lifecycle. This is the phase you need to pay the most attention to. The more functional your app is and the more modules it includes, the more time for coding is needed. If you plan everything thoroughly in advance, there won’t be any unpredictable situations like hiring more developers, etc. It is necessary to monitor the progress of the project according to the scheduled deadlines and get in touch with the team if something goes wrong.

Step 6. Implementation

On this custom development stage, the product is implemented and integrated within the already existing systems and deployed in the target environment. The more complex systems your product uses (CRM, CMS, ERP, etc.), the more time you should spend on this lifecycle stage.

Step 7. Testing and Launch

After the successful deployment, QA and security engineers test the software for errors, bugs, and safety issues. This stage helps you save time and effort on fixing bugs after the launch. It also enhances the user experience with your custom app or website.

Software Testing

The SDLC is not over when the custom product is launched.

Step 8. Improving

Having presented the custom application or website to the end-users, you shouldn’t relax. It is time to track their experience and enhance your product according to their needs. For custom software development, you can implement analytical tools that are going to do a great deal of monitoring the user activity.

Final Thoughts

To boost your company to a new level and make it stand out among the competitors, you should consider the option of custom software development. This way, you create more personalized solutions for your demands and aims. The SDLC includes many processes, each of them being significant for delivering a high-quality result.
