web application development process flow - blog cover

Mapping the right web application development process flow is the key to success for a project of any size. Despite the fact that the development of the web-based app is pretty similar to the regular desktop application, it has some differences that may impact the overall process and make it more complex in some aspects. In this article, we are going to explain each stage of the web application development process, name key specialists who can take part in the project, and map their areas of responsibility.

Web app development services have become a critical part of the modern business landscape. With the rise of tech innovations and the increasing importance of digital technologies, companies need to create web applications that are user-friendly, secure, and capable of delivering a great user experience. However, the process of developing a web application is not straightforward. It involves a structured approach to ensure that the application meets the business’s needs and goals. Let’s focus on every stage of the web application development process to find more details.

web application development process


The first step of custom web application development aims to give an overview of the problem we want to be solved and/or our needs. If the needs aren’t well understood, it will lead to a failure in building a web app that aims to serve the purposes. The following questions have to be answered once this first step is done:

  • What are the underlying needs behind the application to be built?
  • What problems should the app solve?
  • What needs does the application fill? What will be the impact on our business?
  • How will the application be used?
  • What could be the consequences of the delay in building the app for our business?


In the previous step, the goal was to identify the objectives of web app implementation. The objectives can be complex, and the business logic is often quite complex. It is then important at this stage that these complex objectives can be broken down into more manageable tasks and, therefore, easier to implement, validate, and test.

At the end of this step, the following tasks should have been completed:

  • Reformulate the underlying needs and goals
  • Think in terms of the steps needed to complete the project
  • Identify each different feature and module
  • Break down every goal into simple tasks
  • Consolidate the different analyses and approaches in a document so that validation can be carried out.


Experience is a good ally when it comes to making a good estimation. If a similar task has been done before, it becomes easier to give an accurate estimation, and time tracking becomes our reference. From the previous step, we are able to have all the pieces we are going to put together from end to end. For each task, we analyze its complexity and do a classification.

  • Perform a complexity analysis on each task
  • Classify each task
  • List all required development for each task: UI, logic, test.

What is the cost of web application development?

We have already touched on this subject in one of our latest articles. One of the key takeaways from that research is that we have to determine the web application development process flow first to understand the cost. Creating web applications requires a process; creating a great web app requires a strong one.

The estimation gives us an idea of the time needed to complete the whole project. During this step, our goal is to answer the following questions: who is doing what and when? What is the best technical approach?

  • Order each task in order to know which one should/must go before another
  • Analyze dependency between all the tasks
  • Identify every task that can be done in parallel
  • Elaborate a timeline according to available resources or in case it is possible to have all the resources we need, identify the number of resources needed, and then plan the project
  • Make an architectural choice.

Generally, at this stage, the financial and technical side of the web application creation is settled down, and we have an idea of the budget.


This is the most well-known step. Once the product requirements document is established, the development phase can start. The goal of this phase is to create an application that meets the needs identified in the previous steps. As the needs generally evolve and new ideas of implementation may arise during the implementation phase, it is generally advised to use a methodology that allows flexibility and proactivity.

With each iteration in Agile methodology, we make sure that development is achieved towards the goals defined in the product requirements document.

The product requirements documentation should be used to implement all features, and an efficient approach should be chosen in order to make sure the codes are behaving as expected by the specification document. TDD is one approach that aims to make sure that tests are dressed to test and simulate real behavior. Testing helps actors involved in the web application development process understand the code’s purposes and makes the handout process easier. Good code coverage has proven to minimize bugs and is proof of the good design for easy post-production support and maintenance and easy system evolution.


The testing phase is critical in ensuring the web application is reliable, secure, and performs well. Performance testing, security testing, compatibility testing, user acceptance testing, and quality assurance testing are performed in this phase. For example, during the user acceptance test, a test group of users validates the set of features and report bugs, if any. If there are changes to be made, they can be discussed with the project manager, who will advise about the best way to take inputs and feedback into consideration. 


Once every feature in a given release is validated and all the bugs reported fixed, the deployment phase can start. It may be the first launch or deployment of the new release; this is the moment when the web application will run in its real environment.

Some behaviors only appear in a production environment, such as load balancer performance; it is important to allow time for support and maintenance to fix any bugs or performance issues that are discovered after the application goes live.

New ideas for extension may appear once the application is up and running; the post-production phase is the best moment to discuss other needs.
